+Get the detailed info related with the IPMI device
+--------------------------------------------------
+
+Some users need more detailed information about a device, like where
+the address came from or the raw base device for the IPMI interface.
+You can use the IPMI smi_watcher to catch the IPMI interfaces as they
+come or go, and to grab the information, you can use the function
+ipmi_get_smi_info(), which returns the following structure:
+
+struct ipmi_smi_info {
+ enum ipmi_addr_src addr_src;
+ struct device *dev;
+ union {
+ struct {
+ void *acpi_handle;
+ } acpi_info;
+ } addr_info;
+};
+
+Currently special info for only for SI_ACPI address sources is
+returned. Others may be added as necessary.
+
+Note that the dev pointer is included in the above structure, and
+assuming ipmi_smi_get_info returns success, you must call put_device
+on the dev pointer.

+Hierarchical Cgroups
+====================
+- Currently none of the IO control policy supports hierarhical groups. But
+ cgroup interface does allow creation of hierarhical cgroups and internally
+ IO policies treat them as flat hierarchy.
+
+ So this patch will allow creation of cgroup hierarhcy but at the backend

+
+ Down the line we can implement hierarchical accounting/control support
+ and also introduce a new cgroup file "use_hierarchy" which will control
+ whether cgroup hierarchy is viewed as flat or hierarchical by the policy..
+ This is how memory controller also has implemented the things.

+Device-mapper RAID (dm-raid) is a bridge from DM to MD. It
+provides a way to use device-mapper interfaces to access the MD RAID
+drivers.
+
+As with all device-mapper targets, the nominal public interfaces are the
+constructor (CTR) tables and the status outputs (both STATUSTYPE_INFO
+and STATUSTYPE_TABLE). The CTR table looks like the following:
+
+1: <s> <l> raid \
+2: <raid_type> <#raid_params> <raid_params> \
+3: <#raid_devs> <meta_dev1> <dev1> .. <meta_devN> <devN>
+
+Line 1 contains the standard first three arguments to any device-mapper
+target - the start, length, and target type fields. The target type in
+this case is "raid".
+
+Line 2 contains the arguments that define the particular raid
+type/personality/level, the required arguments for that raid type, and
+any optional arguments. Possible raid types include: raid4, raid5_la,
+raid5_ls, raid5_rs, raid6_zr, raid6_nr, and raid6_nc. (raid1 is
+planned for the future.) The list of required and optional parameters
+is the same for all the current raid types. The required parameters are
+positional, while the optional parameters are given as key/value pairs.
+The possible parameters are as follows:
+ <chunk_size> Chunk size in sectors.
+ [[no]sync] Force/Prevent RAID initialization
+ [rebuild <idx>] Rebuild the drive indicated by the index
+ [daemon_sleep <ms>] Time between bitmap daemon work to clear bits
+ [min_recovery_rate <kB/sec/disk>] Throttle RAID initialization
+ [max_recovery_rate <kB/sec/disk>] Throttle RAID initialization
+ [max_write_behind <sectors>] See '-write-behind=' (man mdadm)
+ [stripe_cache <sectors>] Stripe cache size for higher RAIDs
+
+Line 3 contains the list of devices that compose the array in
+metadata/data device pairs. If the metadata is stored separately, a '-'
+is given for the metadata device position. If a drive has failed or is
+missing at creation time, a '-' can be given for both the metadata and
+data drives for a given position.
+
+NB. Currently all metadata devices must be specified as '-'.
+
+Examples:
+# RAID4 - 4 data drives, 1 parity
+# No metadata devices specified to hold superblock/bitmap info
+# Chunk size of 1MiB
+# (Lines separated for easy reading)
+0 1960893648 raid \
+ raid4 1 2048 \
+ 5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81
+
+# RAID4 - 4 data drives, 1 parity (no metadata devices)
+# Chunk size of 1MiB, force RAID initialization,
+# min recovery rate at 20 kiB/sec/disk
+0 1960893648 raid \
+ raid4 4 2048 min_recovery_rate 20 sync\
+ 5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81
+
+Performing a 'dmsetup table' should display the CTR table used to
+construct the mapping (with possible reordering of optional
+parameters).
+
+Performing a 'dmsetup status' will yield information on the state and
+health of the array. The output is as follows:
+1: <s> <l> raid \
+2: <raid_type> <#devices> <1 health char for each dev> <resync_ratio>
+
+Line 1 is standard DM output. Line 2 is best shown by example:
+ 0 1960893648 raid raid4 5 AAAAA 2/490221568
+Here we can see the RAID type is raid4, there are 5 devices - all of
+which are 'A'live, and the array is 2/490221568 complete with recovery.

+Description
+-----------
+
+The DS620 is a (one instance) digital thermometer and thermostat. It has both
+high and low temperature limits which can be user defined (i.e. programmed
+into non-volatile on-chip registers). Temperature range is -55 degree Celsius
+to +125. Between 0 and 70 degree Celsius, accuracy is 0.5 Kelvin. The value
+returned via sysfs displays post decimal positions.
+
+The thermostat function works as follows: When configured via platform_data
+(struct ds620_platform_data) .pomode == 0 (default), the thermostat output pin
+PO is always low. If .pomode == 1, the thermostat is in PO_LOW mode. I.e., the
+output pin PO becomes active when the temperature falls below temp1_min and
+stays active until the temperature goes above temp1_max.
+
+Likewise, with .pomode == 2, the thermostat is in PO_HIGH mode. I.e., the PO
+output pin becomes active when the temperature goes above temp1_max and stays
+active until the temperature falls below temp1_min.
+
+The PO output pin of the DS620 operates active-low.

+
+Description
+-----------
+
+The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of
+only 3 x 3 mm footprint and 1.1 mm height. The difference between the two
+devices is the higher level of precision of the SHT25 (1.8% relative humidity,
+0.2 degree Celsius) compared with the SHT21 (2.0% relative humidity,
+0.3 degree Celsius).
+
+The devices communicate with the I2C protocol. All sensors are set to the same
+I2C address 0x40, so an entry with I2C_BOARD_INFO("sht21", 0x40) can be used
+in the board setup code.
+

+
+temp1_input - temperature input
+humidity1_input - humidity input
+
+Notes
+-----
+
+The driver uses the default resolution settings of 12 bit for humidity and 14
+bit for temperature, which results in typical measurement times of 22 ms for
+humidity and 66 ms for temperature. To keep self heating below 0.1 degree
+Celsius, the device should not be active for more than 10% of the time,
+e.g. maximum two measurements per second at the given resolution.
+
+Different resolutions, the on-chip heater, using the CRC checksum and reading
+the serial number are not supported yet.

+Kernel driver gpio-i2cmux
+
+Author: Peter Korsgaard <peter.korsgaard@barco.com>
+
+Description
+-----------
+
+gpio-i2cmux is an i2c mux driver providing access to I2C bus segments
+from a master I2C bus and a hardware MUX controlled through GPIO pins.
+
+E.G.:
+
+ ---------- ---------- Bus segment 1 - - - - -
+ | | SCL/SDA | |-------------- | |
+ | |------------| |
+ | | | | Bus segment 2 | |
+ | Linux | GPIO 1..N | MUX |--------------- Devices
+ | |------------| | | |
+ | | | | Bus segment M
+ | | | |---------------| |
+ ---------- ---------- - - - - -
+
+SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M
+according to the settings of the GPIO pins 1..N.
+
+Usage
+-----
+
+gpio-i2cmux uses the platform bus, so you need to provide a struct
+platform_device with the platform_data pointing to a struct
+gpio_i2cmux_platform_data with the I2C adapter number of the master
+bus, the number of bus segments to create and the GPIO pins used
+to control it. See include/linux/gpio-i2cmux.h for details.
+
+E.G. something like this for a MUX providing 4 bus segments
+controlled through 3 GPIO pins:
+
+#include <linux/gpio-i2cmux.h>
+#include <linux/platform_device.h>
+
+static const unsigned myboard_gpiomux_gpios[] = {

+ 0, 1, 2, 3
+};
+
+static struct gpio_i2cmux_platform_data myboard_i2cmux_data = {
+ .parent = 1,
+ .base_nr = 2, /* optional */
+ .values = myboard_gpiomux_values,

+ .gpios = myboard_gpiomux_gpios,
+ .n_gpios = ARRAY_SIZE(myboard_gpiomux_gpios),
+ .idle = 4, /* optional */
+};
+

+ .name = "gpio-i2cmux",
+ .id = 0,
+ .dev = {
+ .platform_data = &myboard_i2cmux_data,

+ Trusted and Encrypted Keys
+
+Trusted and Encrypted Keys are two new key types added to the existing kernel
+key ring service. Both of these new types are variable length symmetic keys,
+and in both cases all keys are created in the kernel, and user space sees,
+stores, and loads only encrypted blobs. Trusted Keys require the availability
+of a Trusted Platform Module (TPM) chip for greater security, while Encrypted
+Keys can be used on any system. All user level blobs, are displayed and loaded
+in hex ascii for convenience, and are integrity verified.
+
+Trusted Keys use a TPM both to generate and to seal the keys. Keys are sealed
+under a 2048 bit RSA key in the TPM, and optionally sealed to specified PCR
+(integrity measurement) values, and only unsealed by the TPM, if PCRs and blob
+integrity verifications match. A loaded Trusted Key can be updated with new
+(future) PCR values, so keys are easily migrated to new pcr values, such as
+when the kernel and initramfs are updated. The same key can have many saved
+blobs under different PCR values, so multiple boots are easily supported.
+
+By default, trusted keys are sealed under the SRK, which has the default
+authorization value (20 zeros). This can be set at takeownership time with the
+trouser's utility: "tpm_takeownership -u -z".
+
+Usage:
+ keyctl add trusted name "new keylen [options]" ring
+ keyctl add trusted name "load hex_blob [pcrlock=pcrnum]" ring
+ keyctl update key "update [options]"
+ keyctl print keyid
+
+ options:
+ keyhandle= ascii hex value of sealing key default 0x40000000 (SRK)
+ keyauth= ascii hex auth for sealing key default 0x00...i
+ (40 ascii zeros)
+ blobauth= ascii hex auth for sealed data default 0x00...
+ (40 ascii zeros)
+ blobauth= ascii hex auth for sealed data default 0x00...
+ (40 ascii zeros)
+ pcrinfo= ascii hex of PCR_INFO or PCR_INFO_LONG (no default)
+ pcrlock= pcr number to be extended to "lock" blob
+ migratable= 0|1 indicating permission to reseal to new PCR values,
+ default 1 (resealing allowed)
+
+"keyctl print" returns an ascii hex copy of the sealed key, which is in standard
+TPM_STORED_DATA format. The key length for new keys are always in bytes.
+Trusted Keys can be 32 - 128 bytes (256 - 1024 bits), the upper limit is to fit
+within the 2048 bit SRK (RSA) keylength, with all necessary structure/padding.
+
+Encrypted keys do not depend on a TPM, and are faster, as they use AES for
+encryption/decryption. New keys are created from kernel generated random
+numbers, and are encrypted/decrypted using a specified 'master' key. The
+'master' key can either be a trusted-key or user-key type. The main
+disadvantage of encrypted keys is that if they are not rooted in a trusted key,
+they are only as secure as the user key encrypting them. The master user key
+should therefore be loaded in as secure a way as possible, preferably early in
+boot.
+
+Usage:
+ keyctl add encrypted name "new key-type:master-key-name keylen" ring
+ keyctl add encrypted name "load hex_blob" ring
+ keyctl update keyid "update key-type:master-key-name"
+
+where 'key-type' is either 'trusted' or 'user'.
+
+Examples of trusted and encrypted key usage:
+
+Create and save a trusted key named "kmk" of length 32 bytes:
+
+ $ keyctl add trusted kmk "new 32" @u

+The initial consumer of trusted keys is EVM, which at boot time needs a high
+quality symmetric key for HMAC protection of file metadata. The use of a
+trusted key provides strong guarantees that the EVM key has not been
+compromised by a user level problem, and when sealed to specific boot PCR
+values, protects against boot and offline attacks. Other uses for trusted and
+encrypted keys, such as for disk and file encryption are anticipated.

+ fault guest must reset the reason to 0 before it does
+ something that can generate normal page fault. If during page
+ fault APF reason is 0 it means that this is regular page

+

+ will be sent.

+ If APF is disabled while there are outstanding APFs, they will
+ not be delivered.
+
+ Currently type 2 APF will be always delivered on the same vcpu as

+Kernel driver for the NXP Semiconductors PN544 Near Field
+Communication chip
+
+Author: Jari Vanhala
+Contact: Matti Aaltonen (matti.j.aaltonen at nokia.com)
+
+General
+-------
+
+The PN544 is an integrated transmission module for contactless
+communication. The driver goes under drives/nfc/ and is compiled as a
+module named "pn544". It registers a misc device and creates a device
+file named "/dev/pn544".
+
+Host Interfaces: I2C, SPI and HSU, this driver supports currently only I2C.
+
+The Interface
+-------------
+
+The driver offers a sysfs interface for a hardware test and an IOCTL
+interface for selecting between two operating modes. There are read,
+write and poll functions for transferring messages. The two operating
+modes are the normal (HCI) mode and the firmware update mode.
+
+PN544 is controlled by sending messages from the userspace to the
+chip. The main function of the driver is just to pass those messages
+without caring about the message content.
+
+
+Protocols
+---------
+
+In the normal (HCI) mode and in the firmware update mode read and
+write functions behave a bit differently because the message formats
+or the protocols are different.
+
+In the normal (HCI) mode the protocol used is derived from the ETSI
+HCI specification. The firmware is updated using a specific protocol,
+which is different from HCI.
+
+HCI messages consist of an eight bit header and the message body. The
+header contains the message length. Maximum size for an HCI message is
+33. In HCI mode sent messages are tested for a correct
+checksum. Firmware update messages have the length in the second (MSB)
+and third (LSB) bytes of the message. The maximum FW message length is
+1024 bytes.
+
+For the ETSI HCI specification see
+http://www.etsi.org/WebSite/Technologies/ProtocolSpecification.aspx
+
+The Hardware Test
+-----------------
+
+The idea of the test is that it can performed by reading from the
+corresponding sysfs file. The test is implemented in the board file
+and it should test that PN544 can be put into the firmware update
+mode. If the test is not implemented the sysfs file does not get
+created.
+
+Example:
+> cat /sys/module/pn544/drivers/i2c\:pn544/3-002b/nfc_test
+1
+
+Normal Operation
+----------------
+
+PN544 is powered up when the device file is opened, otherwise it's
+turned off. Only one instance can use the device at a time.
+
+Userspace applications control PN544 with HCI messages. The hardware
+sends an interrupt when data is available for reading. Data is
+physically read when the read function is called by a userspace
+application. Poll() checks the read interrupt state. Configuration and
+self testing are also done from the userspace using read and write.
+
+Example platform data:
+
+static int rx71_pn544_nfc_request_resources(struct i2c_client *client)
+{
+ /* Get and setup the HW resources for the device */
+}
+
+static void rx71_pn544_nfc_free_resources(void)
+{
+ /* Release the HW resources */
+}
+
+static void rx71_pn544_nfc_enable(int fw)
+{
+ /* Turn the device on */
+}
+
+static int rx71_pn544_nfc_test(void)
+{
+ /*
+ * Put the device into the FW update mode
+ * and then back to the normal mode.
+ * Check the behavior and return one on success,
+ * zero on failure.
+ */
+}
+
+static void rx71_pn544_nfc_disable(void)
+{
+ /* turn the power off */
+}
+
+static struct pn544_nfc_platform_data rx71_nfc_data = {
+ .request_resources = rx71_pn544_nfc_request_resources,
+ .free_resources = rx71_pn544_nfc_free_resources,
+ .enable = rx71_pn544_nfc_enable,
+ .test = rx71_pn544_nfc_test,

+----------

+Sometimes one needs to be able not only to catch PPS signals but to produce

+cables to deliver signals using parallel ports, for example.

+Please note that parallel port interrupt occurs only on high->low transition,
+so it is used for PPS assert edge. PPS clear edge can be determined only
+using polling in the interrupt handler which actually can be done way more
+precisely because interrupt handling delays can be quite big and random. So
+current parport PPS generator implementation (pps_gen_parport module) is
+geared towards using the clear edge for time synchronization.
+
+Clear edge polling is done with disabled interrupts so it's better to select
+delay between assert and clear edge as small as possible to reduce system
+latencies. But if it is too small slave won't be able to capture clear edge
+transition. The default of 30us should be good enough in most situations.

+>>>>>>>>>> The TCM v4 fabric module script generator <<<<<<<<<<
+
+Greetings all,
+
+This document is intended to be a mini-HOWTO for using the tcm_mod_builder.py
+script to generate a brand new functional TCM v4 fabric .ko module of your very own,
+that once built can be immediately be loaded to start access the new TCM/ConfigFS
+fabric skeleton, by simply using:
+
+ modprobe $TCM_NEW_MOD
+ mkdir -p /sys/kernel/config/target/$TCM_NEW_MOD
+
+This script will create a new drivers/target/$TCM_NEW_MOD/, and will do the following
+
+ *) Generate new API callers for drivers/target/target_core_fabric_configs.c logic
+ ->make_nodeacl(), ->drop_nodeacl(), ->make_tpg(), ->drop_tpg()
+ ->make_wwn(), ->drop_wwn(). These are created into $TCM_NEW_MOD/$TCM_NEW_MOD_configfs.c
+ *) Generate basic infrastructure for loading/unloading LKMs and TCM/ConfigFS fabric module
+ using a skeleton struct target_core_fabric_ops API template.
+ *) Based on user defined T10 Proto_Ident for the new fabric module being built,
+ the TransportID / Initiator and Target WWPN related handlers for
+ SPC-3 persistent reservation are automatically generated in $TCM_NEW_MOD/$TCM_NEW_MOD_fabric.c
+ using drivers/target/target_core_fabric_lib.c logic.
+ *) NOP API calls for all other Data I/O path and fabric dependent attribute logic
+ in $TCM_NEW_MOD/$TCM_NEW_MOD_fabric.c
+
+tcm_mod_builder.py depends upon the mandatory '-p $PROTO_IDENT' and '-m
+$FABRIC_MOD_name' parameters, and actually running the script looks like:
+
+target:/mnt/sdb/lio-core-2.6.git/Documentation/target# python tcm_mod_builder.py -p iSCSI -m tcm_nab5000

+Would you like to add tcm_nab5000to drivers/target/Kbuild..? [yes,no]: yes
+Would you like to add tcm_nab5000to drivers/target/Kconfig..? [yes,no]: yes
+
+At the end of tcm_mod_builder.py. the script will ask to add the following
+line to drivers/target/Kbuild:
+
+ obj-$(CONFIG_TCM_NAB5000) += tcm_nab5000/
+
+and the same for drivers/target/Kconfig:
+
+ source "drivers/target/tcm_nab5000/Kconfig"
+
+*) Run 'make menuconfig' and select the new CONFIG_TCM_NAB5000 item:
+
+ <M> TCM_NAB5000 fabric module
+
+*) Build using 'make modules', once completed you will have:

+The framework includes a simple notification mechanism, in the form of a
+netlink event. Netlink socket initialization is done during the _init_

+event will be one of:{THERMAL_AUX0, THERMAL_AUX1, THERMAL_CRITICAL,
+THERMAL_DEV_FAULT}. Notification can be sent when the current temperature
+crosses any of the configured thresholds.

+= Transparent Hugepage Support =
+
+== Objective ==
+
+Performance critical computing applications dealing with large memory
+working sets are already running on top of libhugetlbfs and in turn
+hugetlbfs. Transparent Hugepage Support is an alternative means of
+using huge pages for the backing of virtual memory with huge pages
+that supports the automatic promotion and demotion of page sizes and
+without the shortcomings of hugetlbfs.
+
+Currently it only works for anonymous memory mappings but in the
+future it can expand over the pagecache layer starting with tmpfs.
+
+The reason applications are running faster is because of two
+factors. The first factor is almost completely irrelevant and it's not
+of significant interest because it'll also have the downside of
+requiring larger clear-page copy-page in page faults which is a
+potentially negative effect. The first factor consists in taking a
+single page fault for each 2M virtual region touched by userland (so
+reducing the enter/exit kernel frequency by a 512 times factor). This
+only matters the first time the memory is accessed for the lifetime of
+a memory mapping. The second long lasting and much more important
+factor will affect all subsequent accesses to the memory for the whole
+runtime of the application. The second factor consist of two
+components: 1) the TLB miss will run faster (especially with
+virtualization using nested pagetables but almost always also on bare
+metal without virtualization) and 2) a single TLB entry will be
+mapping a much larger amount of virtual memory in turn reducing the
+number of TLB misses. With virtualization and nested pagetables the
+TLB can be mapped of larger size only if both KVM and the Linux guest
+are using hugepages but a significant speedup already happens if only
+one of the two is using hugepages just because of the fact the TLB
+miss is going to run faster.
+
+== Design ==
+
+- "graceful fallback": mm components which don't have transparent
+ hugepage knowledge fall back to breaking a transparent hugepage and
+ working on the regular pages and their respective regular pmd/pte
+ mappings
+
+- if a hugepage allocation fails because of memory fragmentation,
+ regular pages should be gracefully allocated instead and mixed in
+ the same vma without any failure or significant delay and without
+ userland noticing
+
+- if some task quits and more hugepages become available (either
+ immediately in the buddy or through the VM), guest physical memory
+ backed by regular pages should be relocated on hugepages
+ automatically (with khugepaged)
+
+- it doesn't require memory reservation and in turn it uses hugepages
+ whenever possible (the only possible reservation here is kernelcore=
+ to avoid unmovable pages to fragment all the memory but such a tweak
+ is not specific to transparent hugepage support and it's a generic
+ feature that applies to all dynamic high order allocations in the
+ kernel)
+
+- this initial support only offers the feature in the anonymous memory
+ regions but it'd be ideal to move it to tmpfs and the pagecache
+ later
+
+Transparent Hugepage Support maximizes the usefulness of free memory
+if compared to the reservation approach of hugetlbfs by allowing all
+unused memory to be used as cache or other movable (or even unmovable
+entities). It doesn't require reservation to prevent hugepage
+allocation failures to be noticeable from userland. It allows paging
+and all other advanced VM features to be available on the
+hugepages. It requires no modifications for applications to take
+advantage of it.
+
+Applications however can be further optimized to take advantage of
+this feature, like for example they've been optimized before to avoid
+a flood of mmap system calls for every malloc(4k). Optimizing userland
+is by far not mandatory and khugepaged already can take care of long
+lived page allocations even for hugepage unaware applications that
+deals with large amounts of memory.
+
+In certain cases when hugepages are enabled system wide, application
+may end up allocating more memory resources. An application may mmap a
+large region but only touch 1 byte of it, in that case a 2M page might
+be allocated instead of a 4k page for no good. This is why it's
+possible to disable hugepages system-wide and to only have them inside
+MADV_HUGEPAGE madvise regions.
+
+Embedded systems should enable hugepages only inside madvise regions
+to eliminate any risk of wasting any precious byte of memory and to
+only run faster.
+
+Applications that gets a lot of benefit from hugepages and that don't
+risk to lose memory by using hugepages, should use
+madvise(MADV_HUGEPAGE) on their critical mmapped regions.
+
+== sysfs ==
+
+Transparent Hugepage Support can be entirely disabled (mostly for
+debugging purposes) or only enabled inside MADV_HUGEPAGE regions (to
+avoid the risk of consuming more memory resources) or enabled system
+wide. This can be achieved with one of:
+
+echo always >/sys/kernel/mm/transparent_hugepage/enabled
+echo madvise >/sys/kernel/mm/transparent_hugepage/enabled
+echo never >/sys/kernel/mm/transparent_hugepage/enabled
+
+It's also possible to limit defrag efforts in the VM to generate
+hugepages in case they're not immediately free to madvise regions or
+to never try to defrag memory and simply fallback to regular pages
+unless hugepages are immediately available. Clearly if we spend CPU
+time to defrag memory, we would expect to gain even more by the fact
+we use hugepages later instead of regular pages. This isn't always
+guaranteed, but it may be more likely in case the allocation is for a
+MADV_HUGEPAGE region.
+
+echo always >/sys/kernel/mm/transparent_hugepage/defrag
+echo madvise >/sys/kernel/mm/transparent_hugepage/defrag
+echo never >/sys/kernel/mm/transparent_hugepage/defrag
+
+khugepaged will be automatically started when
+transparent_hugepage/enabled is set to "always" or "madvise, and it'll
+be automatically shutdown if it's set to "never".
+
+khugepaged runs usually at low frequency so while one may not want to
+invoke defrag algorithms synchronously during the page faults, it
+should be worth invoking defrag at least in khugepaged. However it's
+also possible to disable defrag in khugepaged:
+
+echo yes >/sys/kernel/mm/transparent_hugepage/khugepaged/defrag
+echo no >/sys/kernel/mm/transparent_hugepage/khugepaged/defrag
+
+You can also control how many pages khugepaged should scan at each
+pass:
+
+/sys/kernel/mm/transparent_hugepage/khugepaged/pages_to_scan
+
+and how many milliseconds to wait in khugepaged between each pass (you
+can set this to 0 to run khugepaged at 100% utilization of one core):
+
+/sys/kernel/mm/transparent_hugepage/khugepaged/scan_sleep_millisecs
+
+and how many milliseconds to wait in khugepaged if there's an hugepage
+allocation failure to throttle the next allocation attempt.
+
+/sys/kernel/mm/transparent_hugepage/khugepaged/alloc_sleep_millisecs
+
+The khugepaged progress can be seen in the number of pages collapsed:
+
+/sys/kernel/mm/transparent_hugepage/khugepaged/pages_collapsed
+
+for each pass:
+
+/sys/kernel/mm/transparent_hugepage/khugepaged/full_scans
+
+== Boot parameter ==
+
+You can change the sysfs boot time defaults of Transparent Hugepage
+Support by passing the parameter "transparent_hugepage=always" or
+"transparent_hugepage=madvise" or "transparent_hugepage=never"
+(without "") to the kernel command line.
+
+== Need of application restart ==
+
+The transparent_hugepage/enabled values only affect future
+behavior. So to make them effective you need to restart any
+application that could have been using hugepages. This also applies to
+the regions registered in khugepaged.
+
+== get_user_pages and follow_page ==
+
+get_user_pages and follow_page if run on a hugepage, will return the
+head or tail pages as usual (exactly as they would do on
+hugetlbfs). Most gup users will only care about the actual physical
+address of the page and its temporary pinning to release after the I/O
+is complete, so they won't ever notice the fact the page is huge. But
+if any driver is going to mangle over the page structure of the tail
+page (like for checking page->mapping or other bits that are relevant
+for the head page and not the tail page), it should be updated to jump
+to check head page instead (while serializing properly against
+split_huge_page() to avoid the head and tail pages to disappear from
+under it, see the futex code to see an example of that, hugetlbfs also
+needed special handling in futex code for similar reasons).
+
+NOTE: these aren't new constraints to the GUP API, and they match the
+same constrains that applies to hugetlbfs too, so any driver capable
+of handling GUP on hugetlbfs will also work fine on transparent
+hugepage backed mappings.
+
+In case you can't handle compound pages if they're returned by
+follow_page, the FOLL_SPLIT bit can be specified as parameter to
+follow_page, so that it will split the hugepages before returning
+them. Migration for example passes FOLL_SPLIT as parameter to
+follow_page because it's not hugepage aware and in fact it can't work
+at all on hugetlbfs (but it instead works fine on transparent
+hugepages thanks to FOLL_SPLIT). migration simply can't deal with
+hugepages being returned (as it's not only checking the pfn of the
+page and pinning it during the copy but it pretends to migrate the
+memory in regular page sizes and with regular pte/pmd mappings).
+
+== Optimizing the applications ==
+
+To be guaranteed that the kernel will map a 2M page immediately in any
+memory region, the mmap region has to be hugepage naturally
+aligned. posix_memalign() can provide that guarantee.
+
+== Hugetlbfs ==
+
+You can use hugetlbfs on a kernel that has transparent hugepage
+support enabled just fine as always. No difference can be noted in
+hugetlbfs other than there will be less overall fragmentation. All
+usual features belonging to hugetlbfs are preserved and
+unaffected. libhugetlbfs will also work fine as usual.
+
+== Graceful fallback ==
+
+Code walking pagetables but unware about huge pmds can simply call
+split_huge_page_pmd(mm, pmd) where the pmd is the one returned by
+pmd_offset. It's trivial to make the code transparent hugepage aware
+by just grepping for "pmd_offset" and adding split_huge_page_pmd where
+missing after pmd_offset returns the pmd. Thanks to the graceful
+fallback design, with a one liner change, you can avoid to write
+hundred if not thousand of lines of complex code to make your code
+hugepage aware.
+
+If you're not walking pagetables but you run into a physical hugepage
+but you can't handle it natively in your code, you can split it by
+calling split_huge_page(page). This is what the Linux VM does before
+it tries to swapout the hugepage for example.
+

+change:

+
+== Locking in hugepage aware code ==
+
+We want as much code as possible hugepage aware, as calling
+split_huge_page() or split_huge_page_pmd() has a cost.
+
+To make pagetable walks huge pmd aware, all you need to do is to call
+pmd_trans_huge() on the pmd returned by pmd_offset. You must hold the
+mmap_sem in read (or write) mode to be sure an huge pmd cannot be
+created from under you by khugepaged (khugepaged collapse_huge_page
+takes the mmap_sem in write mode in addition to the anon_vma lock). If
+pmd_trans_huge returns false, you just fallback in the old code
+paths. If instead pmd_trans_huge returns true, you have to take the
+mm->page_table_lock and re-run pmd_trans_huge. Taking the
+page_table_lock will prevent the huge pmd to be converted into a
+regular pmd from under you (split_huge_page can run in parallel to the
+pagetable walk). If the second pmd_trans_huge returns false, you
+should just drop the page_table_lock and fallback to the old code as
+before. Otherwise you should run pmd_trans_splitting on the pmd. In
+case pmd_trans_splitting returns true, it means split_huge_page is
+already in the middle of splitting the page. So if pmd_trans_splitting
+returns true it's enough to drop the page_table_lock and call
+wait_split_huge_page and then fallback the old code paths. You are
+guaranteed by the time wait_split_huge_page returns, the pmd isn't
+huge anymore. If pmd_trans_splitting returns false, you can proceed to
+process the huge pmd and the hugepage natively. Once finished you can
+drop the page_table_lock.
+
+== compound_lock, get_user_pages and put_page ==
+
+split_huge_page internally has to distribute the refcounts in the head
+page to the tail pages before clearing all PG_head/tail bits from the
+page structures. It can do that easily for refcounts taken by huge pmd
+mappings. But the GUI API as created by hugetlbfs (that returns head
+and tail pages if running get_user_pages on an address backed by any
+hugepage), requires the refcount to be accounted on the tail pages and
+not only in the head pages, if we want to be able to run
+split_huge_page while there are gup pins established on any tail
+page. Failure to be able to run split_huge_page if there's any gup pin
+on any tail page, would mean having to split all hugepages upfront in
+get_user_pages which is unacceptable as too many gup users are
+performance critical and they must work natively on hugepages like
+they work natively on hugetlbfs already (hugetlbfs is simpler because
+hugetlbfs pages cannot be splitted so there wouldn't be requirement of
+accounting the pins on the tail pages for hugetlbfs). If we wouldn't
+account the gup refcounts on the tail pages during gup, we won't know
+anymore which tail page is pinned by gup and which is not while we run
+split_huge_page. But we still have to add the gup pin to the head page
+too, to know when we can free the compound page in case it's never
+splitted during its lifetime. That requires changing not just
+get_page, but put_page as well so that when put_page runs on a tail
+page (and only on a tail page) it will find its respective head page,
+and then it will decrease the head page refcount in addition to the
+tail page refcount. To obtain a head page reliably and to decrease its
+refcount without race conditions, put_page has to serialize against
+__split_huge_page_refcount using a special per-page lock called
+compound_lock.

+
+Description
+-----------
+
+Support is provided through the sysfs w1_slave file. Each opening and
+read sequence of w1_slave file initiates the read of counters and ram
+available in DS2423 pages 12 - 15.
+
+Result of each page is provided as an ASCII output where each counter
+value and associated ram buffer is outpputed to own line.
+
+Each lines will contain the values of 42 bytes read from the counter and
+memory page along the crc=YES or NO for indicating whether the read operation
+was successfull and CRC matched.
+If the operation was successfull, there is also in the end of each line
+a counter value expressed as an integer after c=
+
+Meaning of 42 bytes represented is following:
+ - 1 byte from ram page
+ - 4 bytes for the counter value
+ - 4 zero bytes
+ - 2 bytes for crc16 which was calculated from the data read since the previous crc bytes
+ - 31 remaining bytes from the ram page
+ - crc=YES/NO indicating whether read was ok and crc matched
+ - c=<int> current counter value

+XZ data compression in Linux
+============================
+
+Introduction
+
+ XZ is a general purpose data compression format with high compression
+ ratio and relatively fast decompression. The primary compression
+ algorithm (filter) is LZMA2. Additional filters can be used to improve
+ compression ratio even further. E.g. Branch/Call/Jump (BCJ) filters
+ improve compression ratio of executable data.
+
+ The XZ decompressor in Linux is called XZ Embedded. It supports
+ the LZMA2 filter and optionally also BCJ filters. CRC32 is supported
+ for integrity checking. The home page of XZ Embedded is at
+ <http://tukaani.org/xz/embedded.html>, where you can find the
+ latest version and also information about using the code outside
+ the Linux kernel.
+
+ For userspace, XZ Utils provide a zlib-like compression library
+ and a gzip-like command line tool. XZ Utils can be downloaded from
+ <http://tukaani.org/xz/>.
+
+XZ related components in the kernel
+
+ The xz_dec module provides XZ decompressor with single-call (buffer
+ to buffer) and multi-call (stateful) APIs. The usage of the xz_dec
+ module is documented in include/linux/xz.h.
+
+ The xz_dec_test module is for testing xz_dec. xz_dec_test is not
+ useful unless you are hacking the XZ decompressor. xz_dec_test
+ allocates a char device major dynamically to which one can write
+ .xz files from userspace. The decompressed output is thrown away.
+ Keep an eye on dmesg to see diagnostics printed by xz_dec_test.
+ See the xz_dec_test source code for the details.
+
+ For decompressing the kernel image, initramfs, and initrd, there
+ is a wrapper function in lib/decompress_unxz.c. Its API is the
+ same as in other decompress_*.c files, which is defined in
+ include/linux/decompress/generic.h.
+
+ scripts/xz_wrap.sh is a wrapper for the xz command line tool found
+ from XZ Utils. The wrapper sets compression options to values suitable
+ for compressing the kernel image.
+
+ For kernel makefiles, two commands are provided for use with
+ $(call if_needed). The kernel image should be compressed with
+ $(call if_needed,xzkern) which will use a BCJ filter and a big LZMA2
+ dictionary. It will also append a four-byte trailer containing the
+ uncompressed size of the file, which is needed by the boot code.
+ Other things should be compressed with $(call if_needed,xzmisc)
+ which will use no BCJ filter and 1 MiB LZMA2 dictionary.
+
+Notes on compression options
+
+ Since the XZ Embedded supports only streams with no integrity check or
+ CRC32, make sure that you don't use some other integrity check type
+ when encoding files that are supposed to be decoded by the kernel. With
+ liblzma, you need to use either LZMA_CHECK_NONE or LZMA_CHECK_CRC32
+ when encoding. With the xz command line tool, use --check=none or
+ --check=crc32.
+
+ Using CRC32 is strongly recommended unless there is some other layer
+ which will verify the integrity of the uncompressed data anyway.
+ Double checking the integrity would probably be waste of CPU cycles.
+ Note that the headers will always have a CRC32 which will be validated
+ by the decoder; you can only change the integrity check type (or
+ disable it) for the actual uncompressed data.
+
+ In userspace, LZMA2 is typically used with dictionary sizes of several
+ megabytes. The decoder needs to have the dictionary in RAM, thus big
+ dictionaries cannot be used for files that are intended to be decoded
+ by the kernel. 1 MiB is probably the maximum reasonable dictionary
+ size for in-kernel use (maybe more is OK for initramfs). The presets
+ in XZ Utils may not be optimal when creating files for the kernel,
+ so don't hesitate to use custom settings. Example:
+
+ xz --check=crc32 --lzma2=dict=512KiB inputfile
+
+ An exception to above dictionary size limitation is when the decoder
+ is used in single-call mode. Decompressing the kernel itself is an
+ example of this situation. In single-call mode, the memory usage
+ doesn't depend on the dictionary size, and it is perfectly fine to
+ use a big dictionary: for maximum compression, the dictionary should
+ be at least as big as the uncompressed data itself.
+
+Future plans
+
+ Creating a limited XZ encoder may be considered if people think it is
+ useful. LZMA2 is slower to compress than e.g. Deflate or LZO even at
+ the fastest settings, so it isn't clear if LZMA2 encoder is wanted
+ into the kernel.
+
+ Support for limited random-access reading is planned for the
+ decompression code. I don't know if it could have any use in the
+ kernel, but I know that it would be useful in some embedded projects
+ outside the Linux kernel.
+
+Conformance to the .xz file format specification
+
+ There are a couple of corner cases where things have been simplified
+ at expense of detecting errors as early as possible. These should not
+ matter in practice all, since they don't cause security issues. But
+ it is good to know this if testing the code e.g. with the test files
+ from XZ Utils.
+
+Reporting bugs
+
+ Before reporting a bug, please check that it's not fixed already
+ at upstream. See <http://tukaani.org/xz/embedded.html> to get the
+ latest code.
+
+ Report bugs to <lasse.collin@tukaani.org> or visit #tukaani on
+ Freenode and talk to Larhzu. I don't actively read LKML or other
+ kernel-related mailing lists, so if there's something I should know,
+ you should email to me personally or use IRC.
+
+ Don't bother Igor Pavlov with questions about the XZ implementation
+ in the kernel or about XZ Utils. While these two implementations
+ include essential code that is directly based on Igor Pavlov's code,
+ these implementations aren't maintained nor supported by him.

+ * end of every LLI entry. Observed behaviour shows the DMAC listening
+ * to both the BREQ and SREQ signals (contrary to documented),
+ * transferring data if either is active. The LBREQ and LSREQ signals

+ * after the final transfer signalled by LBREQ or LSREQ. The DMAC
+ * will then move to the next LLI entry.
+ *
+ * Only the former works sanely with scatter lists, so we only implement

- * Set the next domain for the specified object. This
- * may not actually perform the necessary flushing/invaliding though,
- * as that may want to be batched with other set_domain operations
- *
- * This is (we hope) the only really tricky part of gem. The goal
- * is fairly simple -- track which caches hold bits of the object
- * and make sure they remain coherent. A few concrete examples may
- * help to explain how it works. For shorthand, we use the notation
- * (read_domains, write_domain), e.g. (CPU, CPU) to indicate the
- * a pair of read and write domain masks.
- *
- * Case 1: the batch buffer
- *
- * 1. Allocated
- * 2. Written by CPU
- * 3. Mapped to GTT
- * 4. Read by GPU
- * 5. Unmapped from GTT
- * 6. Freed
- *
- * Let's take these a step at a time
- *
- * 1. Allocated
- * Pages allocated from the kernel may still have
- * cache contents, so we set them to (CPU, CPU) always.
- * 2. Written by CPU (using pwrite)
- * The pwrite function calls set_domain (CPU, CPU) and
- * this function does nothing (as nothing changes)
- * 3. Mapped by GTT
- * This function asserts that the object is not
- * currently in any GPU-based read or write domains
- * 4. Read by GPU
- * i915_gem_execbuffer calls set_domain (COMMAND, 0).
- * As write_domain is zero, this function adds in the
- * current read domains (CPU+COMMAND, 0).
- * flush_domains is set to CPU.
- * invalidate_domains is set to COMMAND
- * clflush is run to get data out of the CPU caches
- * then i915_dev_set_domain calls i915_gem_flush to
- * emit an MI_FLUSH and drm_agp_chipset_flush
- * 5. Unmapped from GTT
- * i915_gem_object_unbind calls set_domain (CPU, CPU)
- * flush_domains and invalidate_domains end up both zero
- * so no flushing/invalidating happens
- * 6. Freed
- * yay, done
- *
- * Case 2: The shared render buffer
- *
- * 1. Allocated
- * 2. Mapped to GTT
- * 3. Read/written by GPU
- * 4. set_domain to (CPU,CPU)
- * 5. Read/written by CPU
- * 6. Read/written by GPU
- *
- * 1. Allocated
- * Same as last example, (CPU, CPU)
- * 2. Mapped to GTT
- * Nothing changes (assertions find that it is not in the GPU)
- * 3. Read/written by GPU
- * execbuffer calls set_domain (RENDER, RENDER)
- * flush_domains gets CPU
- * invalidate_domains gets GPU
- * clflush (obj)
- * MI_FLUSH and drm_agp_chipset_flush
- * 4. set_domain (CPU, CPU)
- * flush_domains gets GPU
- * invalidate_domains gets CPU
- * wait_rendering (obj) to make sure all drawing is complete.
- * This will include an MI_FLUSH to get the data from GPU
- * to memory
- * clflush (obj) to invalidate the CPU cache
- * Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
- * 5. Read/written by CPU
- * cache lines are loaded and dirtied
- * 6. Read written by GPU
- * Same as last GPU access
- *
- * Case 3: The constant buffer
- *
- * 1. Allocated
- * 2. Written by CPU
- * 3. Read by GPU
- * 4. Updated (written) by CPU again
- * 5. Read by GPU
- *
- * 1. Allocated
- * (CPU, CPU)
- * 2. Written by CPU
- * (CPU, CPU)
- * 3. Read by GPU

+ * Set the next domain for the specified object. This

+ *
+ * This is (we hope) the only really tricky part of gem. The goal
+ * is fairly simple -- track which caches hold bits of the object
+ * and make sure they remain coherent. A few concrete examples may
+ * help to explain how it works. For shorthand, we use the notation

+ * 3. Mapped to GTT
+ * 4. Read by GPU
+ * 5. Unmapped from GTT
+ * 6. Freed
+ *
+ * Let's take these a step at a time
+ *
+ * 1. Allocated
+ * Pages allocated from the kernel may still have
+ * cache contents, so we set them to (CPU, CPU) always.
+ * 2. Written by CPU (using pwrite)
+ * The pwrite function calls set_domain (CPU, CPU) and
+ * this function does nothing (as nothing changes)
+ * 3. Mapped by GTT
+ * This function asserts that the object is not
+ * currently in any GPU-based read or write domains
+ * 4. Read by GPU
+ * i915_gem_execbuffer calls set_domain (COMMAND, 0).
+ * As write_domain is zero, this function adds in the
+ * current read domains (CPU+COMMAND, 0).
+ * flush_domains is set to CPU.
+ * invalidate_domains is set to COMMAND
+ * clflush is run to get data out of the CPU caches
+ * then i915_dev_set_domain calls i915_gem_flush to
+ * emit an MI_FLUSH and drm_agp_chipset_flush
+ * 5. Unmapped from GTT
+ * i915_gem_object_unbind calls set_domain (CPU, CPU)
+ * flush_domains and invalidate_domains end up both zero
+ * so no flushing/invalidating happens
+ * 6. Freed
+ * yay, done
+ *
+ * Case 2: The shared render buffer
+ *
+ * 1. Allocated
+ * 2. Mapped to GTT
+ * 3. Read/written by GPU
+ * 4. set_domain to (CPU,CPU)
+ * 5. Read/written by CPU
+ * 6. Read/written by GPU
+ *
+ * 1. Allocated
+ * Same as last example, (CPU, CPU)
+ * 2. Mapped to GTT
+ * Nothing changes (assertions find that it is not in the GPU)
+ * 3. Read/written by GPU
+ * execbuffer calls set_domain (RENDER, RENDER)
+ * flush_domains gets CPU
+ * invalidate_domains gets GPU
+ * clflush (obj)
+ * MI_FLUSH and drm_agp_chipset_flush
+ * 4. set_domain (CPU, CPU)
+ * flush_domains gets GPU
+ * invalidate_domains gets CPU
+ * wait_rendering (obj) to make sure all drawing is complete.
+ * This will include an MI_FLUSH to get the data from GPU
+ * to memory

+ bit[3]=0: Enable HW AUX mode detection logic
+ =1: Disable HW AUX mode dettion logic
+ulSB_MMIO_Base_Addr: Physical Base address to SB MMIO space. Driver needs to initialize it for SMU usage.
+
+usRequestedPWMFreqInHz: When it's set to 0x0 by SBIOS: the LCD BackLight is not controlled by GPU(SW).
+ Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;
+
+ When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+ 1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+ VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+ Changing BL using VBIOS function is functional in both driver and non-driver present environment;
+ and enabling VariBri under the driver environment from PP table is optional.
+
+ 2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+ that BL control from GPU is expected.
+ VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+ Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+ it's per platform
+ and enabling VariBri under the driver environment from PP table is optional.

- *
- * - Some hardware uses illegal values as "wildcard" match

- * Linux uses only oneshot alarms.
- *
- * When we see that here, we deal with it by using values from

- * RTC driver prevents "periodic alarm" modes.
- *
- * But this can be racey, because some fields of the RTC timestamp
- * may have wrapped in the interval since we read the RTC alarm,
- * which would lead to us inserting inconsistent values in place
- * of the -1 fields.
- *
- * Reading the alarm and timestamp in the reverse sequence
- * would have the same race condition, and not solve the issue.
- *
- * So, we must first read the RTC timestamp,
- * then read the RTC alarm value,
- * and then read a second RTC timestamp.
- *
- * If any fields of the second timestamp have changed
- * when compared with the first timestamp, then we know
- * our timestamp may be inconsistent with that used by
- * the low-level rtc_read_alarm_internal() function.
- *
- * So, when the two timestamps disagree, we just loop and do
- * the process again to get a fully consistent set of values.
- *
- * This could all instead be done in the lower level driver,

-BATMAN-ADV
-----------
-
-Batman advanced is a new approach to wireless networking which
-does no longer operate on the IP basis. Unlike the batman daemon,
-which exchanges information using UDP packets and sets routing
-tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
-and routes (or better: bridges) Ethernet Frames. It emulates a
-virtual network switch of all nodes participating. Therefore all
-nodes appear to be link local, thus all higher operating proto-
-cols won't be affected by any changes within the network. You can
-run almost any protocol above batman advanced, prominent examples
-are: IPv4, IPv6, DHCP, IPX.
-
-Batman advanced was implemented as a Linux kernel driver to re-
-duce the overhead to a minimum. It does not depend on any (other)
-network driver, and can be used on wifi as well as ethernet lan,
-vpn, etc ... (anything with ethernet-style layer 2).
-
-CONFIGURATION
--------------
-
-Load the batman-adv module into your kernel:
-
-# insmod batman-adv.ko
-
-The module is now waiting for activation. You must add some in-
-terfaces on which batman can operate. After loading the module
-batman advanced will scan your systems interfaces to search for
-compatible interfaces. Once found, it will create subfolders in
-the /sys directories of each supported interface, e.g.
-
-# ls /sys/class/net/eth0/batman_adv/
-# iface_status mesh_iface
-
-If an interface does not have the "batman_adv" subfolder it prob-
-ably is not supported. Not supported interfaces are: loopback,
-non-ethernet and batman's own interfaces.
-
-Note: After the module was loaded it will continuously watch for
-new interfaces to verify the compatibility. There is no need to
-reload the module if you plug your USB wifi adapter into your ma-
-chine after batman advanced was initially loaded.
-
-To activate a given interface simply write "bat0" into its
-"mesh_iface" file inside the batman_adv subfolder:
-
-# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
-
-Repeat this step for all interfaces you wish to add. Now batman
-starts using/broadcasting on this/these interface(s).
-
-By reading the "iface_status" file you can check its status:
-
-# cat /sys/class/net/eth0/batman_adv/iface_status
-# active
-
-To deactivate an interface you have to write "none" into its
-"mesh_iface" file:
-
-# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
-
-
-All mesh wide settings can be found in batman's own interface
-folder:
-
-# ls /sys/class/net/bat0/mesh/
-# aggregated_ogms bonding orig_interval vis_mode
-
-
-There is a special folder for debugging informations:
-
-# ls /sys/kernel/debug/batman_adv/bat0/
-# originators socket transtable_global transtable_local
-# vis_data
-
-
-Some of the files contain all sort of status information regard-
-ing the mesh network. For example, you can view the table of
-originators (mesh participants) with:
-
-# cat /sys/kernel/debug/batman_adv/bat0/originators
-
-Other files allow to change batman's behaviour to better fit your
-requirements. For instance, you can check the current originator
-interval (value in milliseconds which determines how often batman
-sends its broadcast packets):
-
-# cat /sys/class/net/bat0/mesh/orig_interval
-# 1000
-
-and also change its value:
-
-# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
-
-In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh more respon-
-sive to topology changes, but will also increase the overhead.
-
-
-USAGE
------
-
-To make use of your newly created mesh, batman advanced provides
-a new interface "bat0" which you should use from this point on.
-All interfaces added to batman advanced are not relevant any
-longer because batman handles them for you. Basically, one "hands
-over" the data by using the batman interface and batman will make
-sure it reaches its destination.
-
-The "bat0" interface can be used like any other regular inter-
-face. It needs an IP address which can be either statically con-
-figured or dynamically (by using DHCP or similar services):
-
-# NodeA: ifconfig bat0 192.168.0.1
-# NodeB: ifconfig bat0 192.168.0.2
-# NodeB: ping 192.168.0.1
-
-Note: In order to avoid problems remove all IP addresses previ-
-ously assigned to interfaces now used by batman advanced, e.g.
-
-# ifconfig eth0 0.0.0.0
-
-
-VISUALIZATION
--------------
-
-If you want topology visualization, at least one mesh node must
-be configured as VIS-server:
-
-# echo "server" > /sys/class/net/bat0/mesh/vis_mode
-
-Each node is either configured as "server" or as "client" (de-
-fault: "client"). Clients send their topology data to the server
-next to them, and server synchronize with other servers. If there
-is no server configured (default) within the mesh, no topology
-information will be transmitted. With these "synchronizing
-servers", there can be 1 or more vis servers sharing the same (or
-at least very similar) data.
-
-When configured as server, you can get a topology snapshot of
-your mesh:
-
-# cat /sys/kernel/debug/batman_adv/bat0/vis_data
-
-This raw output is intended to be easily parsable and convertable
-with other tools. Have a look at the batctl README if you want a
-vis output in dot or json format for instance and how those out-
-puts could then be visualised in an image.
-
-The raw format consists of comma separated values per entry where
-each entry is giving information about a certain source inter-
-face. Each entry can/has to have the following values:
--> "mac" - mac address of an originator's source interface
- (each line begins with it)
--> "TQ mac value" - src mac's link quality towards mac address
- of a neighbor originator's interface which
- is being used for routing
--> "HNA mac" - HNA announced by source mac
--> "PRIMARY" - this is a primary interface
--> "SEC mac" - secondary mac address of source
- (requires preceding PRIMARY)
-
-The TQ value has a range from 4 to 255 with 255 being the best.
-The HNA entries are showing which hosts are connected to the mesh
-via bat0 or being bridged into the mesh network. The PRIMARY/SEC
-values are only applied on primary interfaces
-
-
-LOGGING/DEBUGGING
------------------
-
-All error messages, warnings and information messages are sent to
-the kernel log. Depending on your operating system distribution
-this can be read in one of a number of ways. Try using the com-
-mands: dmesg, logread, or looking in the files /var/log/kern.log
-or /var/log/syslog. All batman-adv messages are prefixed with
-"batman-adv:" So to see just these messages try
-
-# dmesg | grep batman-adv
-
-When investigating problems with your mesh network it is some-
-times necessary to see more detail debug messages. This must be
-enabled when compiling the batman-adv module. When building bat-
-man-adv as part of kernel, use "make menuconfig" and enable the
-option "B.A.T.M.A.N. debugging".
-
-Those additional debug messages can be accessed using a special
-file in debugfs
-
-# cat /sys/kernel/debug/batman_adv/bat0/log
-
-The additional debug output is by default disabled. It can be en-
-abled during run time. Following log_levels are defined:
-
-0 - All debug output disabled
-1 - Enable messages related to routing / flooding / broadcasting
-2 - Enable route or hna added / changed / deleted
-3 - Enable all messages
-
-The debug output can be changed at runtime using the file
-/sys/class/net/bat0/mesh/log_level. e.g.
-
-# echo 2 > /sys/class/net/bat0/mesh/log_level
-
-will enable debug messages for when routes or HNAs change.
-
-
-BATCTL
-------
-
-As batman advanced operates on layer 2 all hosts participating in
-the virtual switch are completely transparent for all protocols
-above layer 2. Therefore the common diagnosis tools do not work
-as expected. To overcome these problems batctl was created. At
-the moment the batctl contains ping, traceroute, tcpdump and
-interfaces to the kernel module settings.
-
-For more information, please see the manpage (man batctl).
-
-batctl is available on http://www.open-mesh.org/

- the local topologies from all nodes. This file allows

-KNOWN BUILD PROBLEMS
+KNOWN RUNTIME ISSUES
--------------------
-(1) Recent gcc versions may generate the message:
+(1) Intentionally, this driver will not stream material which is unambiguously
+identified by the hardware as copy-protected. Normal video output will be
+present for about a minute but will then freeze when this situation arises.
- warning: the frame size of .... bytes is larger than 1024 bytes
+(2) The controls for luminance, contrast, saturation, hue and volume may not
+always work properly.
-This warning can be suppressed by specifying in the Makefile:
+(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
- EXTRA_CFLAGS += -Wframe-larger-than=8192
-but it would be preferable to remove the cause of the warning.
+INPUT NUMBERING
+---------------
+For the EasyCAP with S-VIDEO input cable the driver regards a request for
+inputs numbered 0 or 1 as referring to CVBS and a request for input
+numbered 5 as referring to S-VIDEO.
-KNOWN RUNTIME ISSUES
---------------------
+For the EasyCAP with four CVBS inputs the driver expects to be asked for
+any one of inputs numbered 1,2,3,4. If input 0 is asked for, it is
+interpreted as input 1.
-(1) Randomly (maybe 5 to 10% of occasions) the driver fails to produce any
-output at start-up. Closing mplayer (or whatever the user program is) and
-restarting it restores normal performance without any other remedial action
-being necessary. The reason for this is not known.
-(2) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected. The video output will freeze
-within about a minute when this situation arises.
+MODULE PARAMETERS
+-----------------
-(3) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
+Three module parameters are defined:
-(4) Reduced-resolution S-Video seems to suffer from moire artefacts. No
-attempt has yet been made to rememdy this.

+ of data and storagebits is the space (after padding) that it
+ occupies in the buffer. shift if specified, is the shift that
+ needs to be applied prior to masking out unused bits. Some
+ devices put their data in the middle of the transferred elements
+ with additional information on both sides. Note that some
+ devices will have additional information in the unused bits
+ so to get a clean value, the bits value must be used to mask
+ the buffer output value appropriately. The storagebits value
+ also specifies the data alignment. So s48/64>>2 will be a
+ signed 48 bit integer stored in a 64 bit location aligned to
+ a a64 bit boundary. To obtain the clean value, shift right 2
+ and apply a mask to zero the top 16 bits of the result.
For other storage combinations this attribute will be extended
appropriately.

-The binding between hdpvr and lirc_zilog is currently disabled,
+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events.
+The 'tx_only' lirc_zilog module parameter will allow ir-kbd-i2c
+and lirc_zilog to coexist in the kernel, if the user requires such a set-up.
+However the IR unit will not work well without coordination between the
+two modules. A shared mutex, for transceiver access locking, needs to be
+supplied by bridge drivers, in struct IR_i2_init_data, to both ir-kbd-i2c
+and lirc_zilog, before they will coexist usefully. This should be fixed
+before moving out of staging.
+
+2. References and locking need careful examination. For cx18 and ivtv PCI
+cards, which are not easily "hot unplugged", the imperfect state of reference
+counting and locking is acceptable if not correct. For USB connected units
+like HD PVR, PVR USB2, HVR-1900, and HVR1950, the likelyhood of an Ooops on
+unplug is probably great. Proper reference counting and locking needs to be
+implemented before this module is moved out of staging.
+
+3. The binding between hdpvr and lirc_zilog is currently disabled,
due to an OOPS reported a few years ago when both the hdpvr and cx18
drivers were loaded in his system. More details can be seen at:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg09163.html
More tests need to be done, in order to fix the reported issue.
-There's a conflict between ir-kbd-i2c: Both provide support for RX events.
-Such conflict needs to be fixed, before moving it out of staging.
+4. In addition to providing a shared mutex for transceiver access
+locking, bridge drivers, if able, should provide a chip reset() callback
+to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
+to perform Z8 chip resets via GPIO manipulations. This will allow lirc_zilog
+to bring the chip back to normal when it hangs, in the same places the
+original lirc_pvr150 driver code does. This is not strictly needed, so it
+is not required to move lirc_zilog out of staging.
+
+5. Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
+and installed on Hauppauge products. When working on either module, developers
+must consider at least the following bridge drivers which mention an IR Rx unit
+at address 0x71 (indicative of a Z8):
-The way I2C probe works, it will try to register the driver twice, one
-for RX and another for TX. The logic needs to be fixed to avoid such
-issue.

- * Values for the BitRate Register (SCBRR)
- *
- * The values are actually divisors for a frequency which can
- * be internal to the SH3 (14.7456MHz) or derived from an external
- * clock source. This driver assumes the internal clock is used;
- * to support using an external clock source, config options or
- * possibly command-line options would need to be added.
- *
- * Also, to support speeds below 2400 (why?) the lower 2 bits of
- * the SCSMR register would also need to be set to non-zero values.
- *
- * -- Greg Banks 27Feb2000
- *
- * Answer: The SCBRR register is only eight bits, and the value in
- * it gets larger with lower baud rates. At around 2400 (depending on
- * the peripherial module clock) you run out of bits. However the
- * lower two bits of SCSMR allow the module clock to be divided down,
- * scaling the value which is needed in SCBRR.

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

+ * which is not used in the kernel. Unsupported
+ * check types return XZ_OPTIONS_ERROR if
+ * XZ_DEC_ANY_CHECK was not defined at build time.
+ * @XZ_MEM_ERROR: Allocating memory failed. This return code is
+ * possible only if the decoder was initialized
+ * with XZ_DYNALLOC. The amount of memory that was
+ * tried to be allocated was no more than the
+ * dict_max argument given to xz_dec_init().
+ * @XZ_MEMLIMIT_ERROR: A bigger LZMA2 dictionary would be needed than

+ * ignores the dict_max argument.
+ * @XZ_FORMAT_ERROR: File format was not recognized (wrong magic
+ * bytes).
+ * @XZ_OPTIONS_ERROR: This implementation doesn't support the requested
+ * compression options. In the decoder this means
+ * that the header CRC32 matches, but the header
+ * itself specifies something that we don't support.
+ * @XZ_DATA_ERROR: Compressed data is corrupt.
+ * @XZ_BUF_ERROR: Cannot make any progress. Details are slightly
+ * different between multi-call and single-call
+ * mode; more information below.
+ *
+ * In multi-call mode, XZ_BUF_ERROR is returned when two consecutive calls
+ * to XZ code cannot consume any input and cannot produce any new output.
+ * This happens when there is no new input available, or the output buffer
+ * is full while at least one output byte is still pending. Assuming your
+ * code is not buggy, you can get this error only when decoding a compressed
+ * stream that is truncated or otherwise corrupt.
+ *
+ * In single-call mode, XZ_BUF_ERROR is returned only when the output buffer
+ * is too small or the compressed input is corrupt in a way that makes the
+ * decoder produce more output than the caller expected. When it is
+ * (relatively) clear that the compressed input is truncated, XZ_DATA_ERROR

+ * @mode: Operation mode
+ * @dict_max: Maximum size of the LZMA2 dictionary (history buffer) for
+ * multi-call decoding. This is ignored in single-call mode
+ * (mode == XZ_SINGLE). LZMA2 dictionary is always 2^n bytes
+ * or 2^n + 2^(n-1) bytes (the latter sizes are less common
+ * in practice), so other values for dict_max don't make sense.
+ * In the kernel, dictionary sizes of 64 KiB, 128 KiB, 256 KiB,
+ * 512 KiB, and 1 MiB are probably the only reasonable values,
+ * except for kernel and initramfs images where a bigger
+ * dictionary can be fine and useful.
+ *
+ * Single-call mode (XZ_SINGLE): xz_dec_run() decodes the whole stream at
+ * once. The caller must provide enough output space or the decoding will
+ * fail. The output space is used as the dictionary buffer, which is why
+ * there is no need to allocate the dictionary as part of the decoder's
+ * internal state.
+ *
+ * Because the output buffer is used as the workspace, streams encoded using
+ * a big dictionary are not a problem in single-call mode. It is enough that
+ * the output buffer is big enough to hold the actual uncompressed data; it
+ * can be smaller than the dictionary size stored in the stream headers.
+ *
+ * Multi-call mode with preallocated dictionary (XZ_PREALLOC): dict_max bytes
+ * of memory is preallocated for the LZMA2 dictionary. This way there is no
+ * risk that xz_dec_run() could run out of memory, since xz_dec_run() will
+ * never allocate any memory. Instead, if the preallocated dictionary is too
+ * small for decoding the given input stream, xz_dec_run() will return
+ * XZ_MEMLIMIT_ERROR. Thus, it is important to know what kind of data will be
+ * decoded to avoid allocating excessive amount of memory for the dictionary.
+ *
+ * Multi-call mode with dynamically allocated dictionary (XZ_DYNALLOC):
+ * dict_max specifies the maximum allowed dictionary size that xz_dec_run()
+ * may allocate once it has parsed the dictionary size from the stream
+ * headers. This way excessive allocations can be avoided while still
+ * limiting the maximum memory usage to a sane value to prevent running the
+ * system out of memory when decompressing streams from untrusted sources.
+ *
+ * On success, xz_dec_init() returns a pointer to struct xz_dec, which is
+ * ready to be used with xz_dec_run(). If memory allocation fails,
+ * xz_dec_init() returns NULL.

+/*
+ * Important notes about in-place decompression
+ *
+ * At least on x86, the kernel is decompressed in place: the compressed data
+ * is placed to the end of the output buffer, and the decompressor overwrites
+ * most of the compressed data. There must be enough safety margin to
+ * guarantee that the write position is always behind the read position.
+ *
+ * The safety margin for XZ with LZMA2 or BCJ+LZMA2 is calculated below.
+ * Note that the margin with XZ is bigger than with Deflate (gzip)!
+ *
+ * The worst case for in-place decompression is that the beginning of
+ * the file is compressed extremely well, and the rest of the file is
+ * uncompressible. Thus, we must look for worst-case expansion when the
+ * compressor is encoding uncompressible data.
+ *
+ * The structure of the .xz file in case of a compresed kernel is as follows.
+ * Sizes (as bytes) of the fields are in parenthesis.
+ *
+ * Stream Header (12)
+ * Block Header:
+ * Block Header (8-12)
+ * Compressed Data (N)
+ * Block Padding (0-3)
+ * CRC32 (4)
+ * Index (8-20)
+ * Stream Footer (12)
+ *
+ * Normally there is exactly one Block, but let's assume that there are
+ * 2-4 Blocks just in case. Because Stream Header and also Block Header
+ * of the first Block don't make the decompressor produce any uncompressed
+ * data, we can ignore them from our calculations. Block Headers of possible
+ * additional Blocks have to be taken into account still. With these
+ * assumptions, it is safe to assume that the total header overhead is
+ * less than 128 bytes.
+ *
+ * Compressed Data contains LZMA2 or BCJ+LZMA2 encoded data. Since BCJ
+ * doesn't change the size of the data, it is enough to calculate the
+ * safety margin for LZMA2.
+ *
+ * LZMA2 stores the data in chunks. Each chunk has a header whose size is
+ * a maximum of 6 bytes, but to get round 2^n numbers, let's assume that
+ * the maximum chunk header size is 8 bytes. After the chunk header, there
+ * may be up to 64 KiB of actual payload in the chunk. Often the payload is
+ * quite a bit smaller though; to be safe, let's assume that an average
+ * chunk has only 32 KiB of payload.
+ *
+ * The maximum uncompressed size of the payload is 2 MiB. The minimum
+ * uncompressed size of the payload is in practice never less than the
+ * payload size itself. The LZMA2 format would allow uncompressed size
+ * to be less than the payload size, but no sane compressor creates such
+ * files. LZMA2 supports storing uncompressible data in uncompressed form,
+ * so there's never a need to create payloads whose uncompressed size is
+ * smaller than the compressed size.
+ *
+ * The assumption, that the uncompressed size of the payload is never
+ * smaller than the payload itself, is valid only when talking about
+ * the payload as a whole. It is possible that the payload has parts where
+ * the decompressor consumes more input than it produces output. Calculating
+ * the worst case for this would be tricky. Instead of trying to do that,
+ * let's simply make sure that the decompressor never overwrites any bytes
+ * of the payload which it is currently reading.
+ *
+ * Now we have enough information to calculate the safety margin. We need
+ * - 128 bytes for the .xz file format headers;
+ * - 8 bytes per every 32 KiB of uncompressed size (one LZMA2 chunk header
+ * per chunk, each chunk having average payload size of 32 KiB); and
+ * - 64 KiB (biggest possible LZMA2 chunk payload size) to make sure that
+ * the decompressor never overwrites anything from the LZMA2 chunk
+ * payload it is currently reading.
+ *
+ * We get the following formula:
+ *
+ * safety_margin = 128 + uncompressed_size * 8 / 32768 + 65536
+ * = 128 + (uncompressed_size >> 12) + 65536
+ *
+ * For comparision, according to arch/x86/boot/compressed/misc.c, the
+ * equivalent formula for Deflate is this:
+ *
+ * safety_margin = 18 + (uncompressed_size >> 12) + 32768
+ *
+ * Thus, when updating Deflate-only in-place kernel decompressor to
+ * support XZ, the fixed overhead has to be increased from 18+32768 bytes
+ * to 128+65536 bytes.

+.TH TURBOSTAT 8
+.SH NAME
+turbostat \- Report processor frequency and idle statistics
+.SH SYNOPSIS
+.ft B
+.B turbostat
+.RB [ "\-v" ]
+.RB [ "\-M MSR#" ]
+.RB command
+.br
+.B turbostat
+.RB [ "\-v" ]
+.RB [ "\-M MSR#" ]
+.RB [ "\-i interval_sec" ]
+.SH DESCRIPTION
+\fBturbostat \fP reports processor topology, frequency
+and idle power state statistics on modern X86 processors.
+Either \fBcommand\fP is forked and statistics are printed
+upon its completion, or statistics are printed periodically.
+
+\fBturbostat \fP
+requires that the processor
+supports an "invariant" TSC, plus the APERF and MPERF MSRs.
+\fBturbostat \fP will report idle cpu power state residency
+on processors that additionally support C-state residency counters.
+
+.SS Options
+The \fB-v\fP option increases verbosity.
+.PP
+The \fB-M MSR#\fP option dumps the specified MSR,
+in addition to the usual frequency and idle statistics.
+.PP
+The \fB-i interval_sec\fP option prints statistics every \fiinterval_sec\fP seconds.
+The default is 5 seconds.
+.PP
+The \fBcommand\fP parameter forks \fBcommand\fP and upon its exit,
+displays the statistics gathered since it was forked.
+.PP
+.SH FIELD DESCRIPTIONS
+.nf
+\fBpkg\fP processor package number.
+\fBcore\fP processor core number.
+\fBCPU\fP Linux CPU (logical processor) number.
+\fB%c0\fP percent of the interval that the CPU retired instructions.
+\fBGHz\fP average clock rate while the CPU was in c0 state.
+\fBTSC\fP average GHz that the TSC ran during the entire interval.
+\fB%c1, %c3, %c6\fP show the percentage residency in hardware core idle states.
+\fB%pc3, %pc6\fP percentage residency in hardware package idle states.
+.fi
+.PP
+.SH EXAMPLE
+Without any parameters, turbostat prints out counters ever 5 seconds.
+(override interval with "-i sec" option, or specify a command
+for turbostat to fork).
+
+The first row of statistics reflect the average for the entire system.
+Subsequent rows show per-CPU statistics.

+.SH VERBOSE EXAMPLE
+The "-v" option adds verbosity to the output:
+
+.nf
+GenuineIntel 11 CPUID levels; family:model:stepping 0x6:2c:2 (6:44:2)
+12 * 133 = 1600 MHz max efficiency
+25 * 133 = 3333 MHz TSC frequency
+26 * 133 = 3467 MHz max turbo 4 active cores
+26 * 133 = 3467 MHz max turbo 3 active cores
+27 * 133 = 3600 MHz max turbo 2 active cores
+27 * 133 = 3600 MHz max turbo 1 active cores
+
+.fi
+The \fBmax efficiency\fP frequency, a.k.a. Low Frequency Mode, is the frequency
+available at the minimum package voltage. The \fBTSC frequency\fP is the nominal
+maximum frequency of the processor if turbo-mode were not available. This frequency
+should be sustainable on all CPUs indefinitely, given nominal power and cooling.
+The remaining rows show what maximum turbo frequency is possible
+depending on the number of idle cores. Note that this information is
+not available on all processors.
+.SH FORK EXAMPLE
+If turbostat is invoked with a command, it will fork that command
+and output the statistics gathered when the command exits.
+eg. Here a cycle soaker is run on 1 CPU (see %c0) for a few seconds
+until ^C while the other CPUs are mostly idle:

+Above the cycle soaker drives cpu9 up 3.6 Ghz turbo limit
+while the other processors are generally in various states of idle.
+
+Note that cpu3 is an HT sibling sharing core9
+with cpu9, and thus it is unable to get to an idle state
+deeper than c1 while cpu9 is busy.
+
+Note that turbostat reports average GHz of 3.61, while
+the arithmetic average of the GHz column above is 3.24.
+This is a weighted average, where the weight is %c0. ie. it is the total number of
+un-halted cycles elapsed per time divided by the number of CPUs.
+.SH NOTES
+
+.B "turbostat "
+must be run as root.
+
+.B "turbostat "
+reads hardware counters, but doesn't write them.
+So it will not interfere with the OS or other programs, including
+multiple invocations of itself.
+
+\fBturbostat \fP
+may work poorly on Linux-2.6.20 through 2.6.29,
+as \fBacpi-cpufreq \fPperiodically cleared the APERF and MPERF
+in those kernels.
+
+The APERF, MPERF MSRs are defined to count non-halted cycles.
+Although it is not guaranteed by the architecture, turbostat assumes
+that they count at TSC rate, which is true on all processors tested to date.

+.SH DESCRIPTION
+\fBx86_energy_perf_policy\fP
+allows software to convey
+its policy for the relative importance of performance
+versus energy savings to the processor.
+
+The processor uses this information in model-specific ways
+when it must select trade-offs between performance and
+energy efficiency.
+
+This policy hint does not supersede Processor Performance states
+(P-states) or CPU Idle power states (C-states), but allows
+software to have influence where it would otherwise be unable
+to express a preference.
+
+For example, this setting may tell the hardware how
+aggressively or conservatively to control frequency
+in the "turbo range" above the explicitly OS-controlled
+P-state frequency range. It may also tell the hardware
+how aggressively is should enter the OS requested C-states.
+
+Support for this feature is indicated by CPUID.06H.ECX.bit3
+per the Intel Architectures Software Developer's Manual.
+
+.SS Options
+\fB-c\fP limits operation to a single CPU.
+The default is to operate on all CPUs.
+Note that MSR_IA32_ENERGY_PERF_BIAS is defined per
+logical processor, but that the initial implementations
+of the MSR were shared among all processors in each package.
+.PP
+\fB-v\fP increases verbosity. By default
+x86_energy_perf_policy is silent.
+.PP
+\fB-r\fP is for "read-only" mode - the unchanged state
+is read and displayed.
+.PP
+.I performance
+Set a policy where performance is paramount.
+The processor will be unwilling to sacrifice any performance
+for the sake of energy saving. This is the hardware default.
+.PP
+.I normal
+Set a policy with a normal balance between performance and energy efficiency.
+The processor will tolerate minor performance compromise
+for potentially significant energy savings.
+This reasonable default for most desktops and servers.
+.PP
+.I powersave
+Set a policy where the processor can accept
+a measurable performance hit to maximize energy efficiency.
+.PP
+.I n
+Set MSR_IA32_ENERGY_PERF_BIAS to the specified number.
+The range of valid numbers is 0-15, where 0 is maximum
+performance and 15 is maximum energy efficiency.

+# Config file for ktest.pl
+#
+# Note, all paths must be absolute
+#
+
+# Options set in the beginning of the file are considered to be
+# default options. These options can be overriden by test specific
+# options, with the following exceptions:
+#
+# LOG_FILE
+# CLEAR_LOG
+# POWEROFF_ON_SUCCESS
+# REBOOT_ON_SUCCESS
+#
+# Test specific options are set after the label:
+#
+# TEST_START
+#
+# The options after a TEST_START label are specific to that test.
+# Each TEST_START label will set up a new test. If you want to
+# perform a test more than once, you can add the ITERATE label
+# to it followed by the number of times you want that test
+# to iterate. If the ITERATE is left off, the test will only
+# be performed once.
+#
+# TEST_START ITERATE 10
+#
+# You can skip a test by adding SKIP (before or after the ITERATE
+# and number)
+#
+# TEST_START SKIP
+#
+# TEST_START SKIP ITERATE 10
+#
+# TEST_START ITERATE 10 SKIP
+#
+# The SKIP label causes the options and the test itself to be ignored.
+# This is useful to set up several different tests in one config file, and
+# only enabling the ones you want to use for a current test run.
+#
+# You can add default options anywhere in the file as well
+# with the DEFAULTS tag. This allows you to have default options
+# after the test options to keep the test options at the top
+# of the file. You can even place the DEFAULTS tag between
+# test cases (but not in the middle of a single test case)
+#
+# TEST_START
+# MIN_CONFIG = /home/test/config-test1
+#
+# DEFAULTS
+# MIN_CONFIG = /home/test/config-default
+#
+# TEST_START ITERATE 10
+#
+# The above will run the first test with MIN_CONFIG set to
+# /home/test/config-test-1. Then 10 tests will be executed
+# with MIN_CONFIG with /home/test/config-default.
+#
+# You can also disable defaults with the SKIP option
+#
+# DEFAULTS SKIP
+# MIN_CONFIG = /home/test/config-use-sometimes
+#
+# DEFAULTS
+# MIN_CONFIG = /home/test/config-most-times
+#
+# The above will ignore the first MIN_CONFIG. If you want to
+# use the first MIN_CONFIG, remove the SKIP from the first
+# DEFAULTS tag and add it to the second. Be careful, options
+# may only be declared once per test or default. If you have
+# the same option name under the same test or as default
+# ktest will fail to execute, and no tests will run.

+# The test types may be:
+# build - only build the kernel, do nothing else
+# boot - build and boot the kernel
+# test - build, boot and if TEST is set, run the test script
+# (If TEST is not set, it defaults back to boot)

+# useconfig:/path/to/config - use the given config and run
+# oldconfig on it.
+# This option is ignored if TEST_TYPE is patchcheck or bisect
+#BUILD_TYPE = randconfig

+# If you need an initrd, you can add a script or code here to install
+# it. The environment variable KERNEL_VERSION will be set to the
+# kernel version that is used. Remember to add the initrd line
+# to your grub menu.lst file.
+#
+# Here's a couple of examples to use:
+#POST_INSTALL = ssh user@target /sbin/mkinitrd --allow-missing -f /boot/initramfs-test.img $KERNEL_VERSION

+# Way to reboot the box to the test kernel.
+# Only valid options so far are "grub" and "script"
+# (default grub)
+# If you specify grub, it will assume grub version 1
+# and will search in /boot/grub/menu.lst for the title $GRUB_MENU
+# and select that target to reboot to the kernel. If this is not
+# your setup, then specify "script" and have a command or script

+# $ exit
+# $ cd linux.git
+# $ rm .config
+# $ make LSMOD=mymods localyesconfig

+# # lsmod | cut -d' ' -f1 | xargs rmmod
+#
+# repeat the above several times
+#
+# # lsmod > mymods
+# # reboot
+#
+# May need to reboot to get your network back to copy the mymods
+# to the host, and then remove the previous .config and run the
+# localyesconfig again. The CONFIG_MIN generated like this will
+# not guarantee network activity to the box so the TEST_TYPE of
+# test may fail.
+#
+# You might also want to set:

+# They are ignored in the DEFAULTS sections.
+#
+# All of these are optional and undefined by default, although
+# some of these options are required for TEST_TYPE of patchcheck
+# and bisect.
+#
+#
+# CHECKOUT = branch
+#
+# If the BUILD_DIR is a git repository, then you can set this option
+# to checkout the given branch before running the TEST. If you
+# specify this for the first run, that branch will be used for
+# all preceding tests until a new CHECKOUT is set.
+#
+#
+#
+# For TEST_TYPE = patchcheck
+#
+# This expects the BUILD_DIR to be a git repository, and
+# will checkout the PATCHCHECK_START commit.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# The MIN_CONFIG will be used for all builds of the patchcheck. The build type
+# used for patchcheck is oldconfig.
+#
+# PATCHCHECK_START is required and is the first patch to
+# test (the SHA1 of the commit). You may also specify anything
+# that git checkout allows (branch name, tage, HEAD~3).
+#
+# PATCHCHECK_END is the last patch to check (default HEAD)
+#
+# PATCHCHECK_TYPE is required and is the type of test to run:
+# build, boot, test.
+#
+# Note, the build test will look for warnings, if a warning occurred
+# in a file that a commit touches, the build will fail.
+#
+# If BUILD_NOCLEAN is set, then make mrproper will not be run on
+# any of the builds, just like all other TEST_TYPE tests. But
+# what makes patchcheck different from the other tests, is if
+# BUILD_NOCLEAN is not set, only the first and last patch run
+# make mrproper. This helps speed up the test.
+#
+# Example:
+# TEST_START
+# TEST_TYPE = patchcheck
+# CHECKOUT = mybranch
+# PATCHCHECK_TYPE = boot
+# PATCHCHECK_START = 747e94ae3d1b4c9bf5380e569f614eb9040b79e7
+# PATCHCHECK_END = HEAD~2
+#
+#
+#
+# For TEST_TYPE = bisect
+#
+# You can specify a git bisect if the BUILD_DIR is a git repository.
+# The MIN_CONFIG will be used for all builds of the bisect. The build type
+# used for bisecting is oldconfig.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# BISECT_TYPE is the type of test to perform:
+# build - bad fails to build
+# boot - bad builds but fails to boot
+# test - bad boots but fails a test
+#
+# BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
+# BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
+#
+# The above three options are required for a bisect operation.
+#
+# BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
+#
+# If an operation failed in the bisect that was not expected to
+# fail. Then the test ends. The state of the BUILD_DIR will be
+# left off at where the failure occurred. You can examine the
+# reason for the failure, and perhaps even find a git commit
+# that would work to continue with. You can run:
+#
+# git bisect log > /path/to/replay/file
+#
+# The adding:
+#
+# BISECT_REPLAY= /path/to/replay/file
+#
+# And running the test again. The test will perform the initial
+# git bisect start, git bisect good, and git bisect bad, and
+# then it will run git bisect replay on this file, before
+# continuing with the bisect.
+#
+# BISECT_START = commit (optional, default undefined)
+#
+# As with BISECT_REPLAY, if the test failed on a commit that
+# just happen to have a bad commit in the middle of the bisect,
+# and you need to skip it. If BISECT_START is defined, it
+# will checkout that commit after doing the initial git bisect start,
+# git bisect good, git bisect bad, and running the git bisect replay
+# if the BISECT_REPLAY is set.
+#
+# BISECT_REVERSE = 1 (optional, default 0)
+#
+# In those strange instances where it was broken forever
+# and you are trying to find where it started to work!
+# Set BISECT_GOOD to the commit that was last known to fail
+# Set BISECT_BAD to the commit that is known to start working.
+# With BISECT_REVERSE = 1, The test will consider failures as
+# good, and success as bad.
+#
+# BISECT_CHECK = 1 (optional, default 0)
+#
+# Just to be sure the good is good and bad is bad, setting
+# BISECT_CHECK to 1 will start the bisect by first checking
+# out BISECT_BAD and makes sure it fails, then it will check
+# out BISECT_GOOD and makes sure it succeeds before starting
+# the bisect (it works for BISECT_REVERSE too).
+#
+# You can limit the test to just check BISECT_GOOD or
+# BISECT_BAD with BISECT_CHECK = good or
+# BISECT_CHECK = bad, respectively.
+#
+# Example:
+# TEST_START
+# TEST_TYPE = bisect
+# BISECT_GOOD = v2.6.36
+# BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
+# BISECT_TYPE = build
+# MIN_CONFIG = /home/test/config-bisect
+#
+#
+#
+# For TEST_TYPE = config_bisect
+#
+# In those cases that you have two different configs. One of them
+# work, the other does not, and you do not know what config causes
+# the problem.
+# The TEST_TYPE config_bisect will bisect the bad config looking for
+# what config causes the failure.
+#
+# The way it works is this:
+#
+# First it finds a config to work with. Since a different version, or
+# MIN_CONFIG may cause different dependecies, it must run through this
+# preparation.
+#
+# Overwrites any config set in the bad config with a config set in
+# either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs
+# are minimal and do not disable configs you want to test:
+# (ie. # CONFIG_FOO is not set).
+#
+# An oldconfig is run on the bad config and any new config that
+# appears will be added to the configs to test.
+#
+# Finally, it generates a config with the above result and runs it
+# again through make oldconfig to produce a config that should be
+# satisfied by kconfig.
+#
+# Then it starts the bisect.
+#
+# The configs to test are cut in half. If all the configs in this
+# half depend on a config in the other half, then the other half
+# is tested instead. If no configs are enabled by either half, then
+# this means a circular dependency exists and the test fails.
+#
+# A config is created with the test half, and the bisect test is run.
+#
+# If the bisect succeeds, then all configs in the generated config
+# are removed from the configs to test and added to the configs that
+# will be enabled for all builds (they will be enabled, but not be part
+# of the configs to examine).
+#
+# If the bisect fails, then all test configs that were not enabled by
+# the config file are removed from the test. These configs will not
+# be enabled in future tests. Since current config failed, we consider
+# this to be a subset of the config that we started with.
+#
+# When we are down to one config, it is considered the bad config.
+#
+# Note, the config chosen may not be the true bad config. Due to
+# dependencies and selections of the kbuild system, mulitple
+# configs may be needed to cause a failure. If you disable the
+# config that was found and restart the test, if the test fails
+# again, it is recommended to rerun the config_bisect with a new
+# bad config without the found config enabled.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# CONFIG_BISECT_TYPE is the type of test to perform:
+# build - bad fails to build
+# boot - bad builds but fails to boot
+# test - bad boots but fails a test
+#
+# CONFIG_BISECT is the config that failed to boot
+#
+# Example:
