From 494a43bb188c10b9b21375bbfe2691e41e3cb145 Mon Sep 17 00:00:00 2001 From: Alan Olsen Date: Mon, 26 Apr 2010 10:50:19 -0700 Subject: Moorestown "Post Beta" nand driver. Contains the fixes for nand corruption with the watchdog driver. New features compares to MRST NAND driver Post Alpah2 2.0: 1. Enable CDMA feature of NAND controller How to use this driver: The same with before. That is, to enable this driver, you can set CONFIG_MRST_NAND=y CONFIG_MRST_NAND_HW=y Signed-off-by: Gao Yunpeng Signed-off-by: Alan Olsen --- drivers/block/Kconfig | 2 + drivers/block/Makefile | 2 + drivers/block/spectra/Kconfig | 27 + drivers/block/spectra/Makefile | 7 + drivers/block/spectra/README | 29 + drivers/block/spectra/ffsdefs.h | 58 + drivers/block/spectra/ffsport.c | 847 ++++++ drivers/block/spectra/ffsport.h | 84 + drivers/block/spectra/flash.c | 4731 +++++++++++++++++++++++++++++++ drivers/block/spectra/flash.h | 198 ++ drivers/block/spectra/lld.c | 258 ++ drivers/block/spectra/lld.h | 111 + drivers/block/spectra/lld_cdma.c | 910 ++++++ drivers/block/spectra/lld_cdma.h | 123 + drivers/block/spectra/lld_emu.c | 780 +++++ drivers/block/spectra/lld_emu.h | 51 + drivers/block/spectra/lld_nand.c | 2601 +++++++++++++++++ drivers/block/spectra/lld_nand.h | 131 + drivers/block/spectra/nand_regs.h | 619 ++++ drivers/block/spectra/spectraswconfig.h | 81 + 20 files changed, 11650 insertions(+) create mode 100644 drivers/block/spectra/Kconfig create mode 100644 drivers/block/spectra/Makefile create mode 100644 drivers/block/spectra/README create mode 100644 drivers/block/spectra/ffsdefs.h create mode 100644 drivers/block/spectra/ffsport.c create mode 100644 drivers/block/spectra/ffsport.h create mode 100644 drivers/block/spectra/flash.c create mode 100644 drivers/block/spectra/flash.h create mode 100644 drivers/block/spectra/lld.c create mode 100644 drivers/block/spectra/lld.h create mode 100644 drivers/block/spectra/lld_cdma.c create mode 100644 drivers/block/spectra/lld_cdma.h create mode 100644 drivers/block/spectra/lld_emu.c create mode 100644 drivers/block/spectra/lld_emu.h create mode 100644 drivers/block/spectra/lld_nand.c create mode 100644 drivers/block/spectra/lld_nand.h create mode 100644 drivers/block/spectra/nand_regs.h create mode 100644 drivers/block/spectra/spectraswconfig.h diff --git a/drivers/block/Kconfig b/drivers/block/Kconfig index 77bfce52e9c..d62b95d2ab0 100644 --- a/drivers/block/Kconfig +++ b/drivers/block/Kconfig @@ -488,4 +488,6 @@ config BLK_DEV_HD If unsure, say N. +source "drivers/block/spectra/Kconfig" + endif # BLK_DEV diff --git a/drivers/block/Makefile b/drivers/block/Makefile index aff5ac925c3..568ba651cb5 100644 --- a/drivers/block/Makefile +++ b/drivers/block/Makefile @@ -38,4 +38,6 @@ obj-$(CONFIG_BLK_DEV_HD) += hd.o obj-$(CONFIG_XEN_BLKDEV_FRONTEND) += xen-blkfront.o obj-$(CONFIG_BLK_DEV_DRBD) += drbd/ +obj-$(CONFIG_MRST_NAND) += spectra/ + swim_mod-objs := swim.o swim_asm.o diff --git a/drivers/block/spectra/Kconfig b/drivers/block/spectra/Kconfig new file mode 100644 index 00000000000..fbece109f6c --- /dev/null +++ b/drivers/block/spectra/Kconfig @@ -0,0 +1,27 @@ + +menuconfig MRST_NAND + tristate "Moorestown NAND Flash controller" + depends on BLOCK + default n + ---help--- + Enable the driver for the NAND Flash controller in Intel Moorestown + Platform + +choice + prompt "Compile for" + depends on MRST_NAND + default MRST_NAND_HW + +config MRST_NAND_HW + bool "Actual hardware mode" + help + Driver communicates with the actual hardware's register interface. + in DMA mode. + +config MRST_NAND_EMU + bool "RAM emulator testing" + help + Driver emulates Flash on a RAM buffer and / or disk file.

Change the prototype of the 'open' method in 'struct comedi_device' to allow this, and change the drivers that use it. Propagate any error to the 'open' file operation. The corresponding 'close' method won't be called when the 'open' method fails, so drivers failing the 'open' need to clean up any mess they created. The dt9812 and serial2002 drivers can now return an error on 'open'. The jr3_pci driver also uses the 'open' method but doesn't fail it.

But really the main problem is that if the pointers were null that would cause problems on the ealier lines. The dereferences would cause an oops and the _release() functions use ->priv to determine which IRQ to free. I looked into it and quite a few of the detach functions assume link->priv is non-null. It seems like we can remove these checks.

This was recently updated to allow and strip off a " * " prefix at the start of each line (well actually, it uses the perl substitution 's/^ ?\* ?//'). The skel.c file contains an instructional comment block about how to format this driver comment block, but the updated 'dump_doc' script mistakenly treats this as a valid driver comment block.

Use of the easycap module as a client of +the videodev module has received very little testing as of June 2010. + + +KNOWN BUILD PROBLEMS +-------------------- + +(1) Recent gcc versions may generate the message: + + warning: the frame size of .... bytes is larger than 1024 bytes + +This warning can be suppressed by specifying in the Makefile: + + EXTRA_CFLAGS += -Wframe-larger-than=8192 + +but it would be preferable to remove the cause of the warning. + + +KNOWN RUNTIME ISSUES +-------------------- + +(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. + +(3) The controls for luminance, contrast, saturation, hue and volume may not +always work properly. + +(4) Reduced-resolution S-Video seems to suffer from moire artefacts. No +attempt has yet been made to rememdy this. + + +SUPPORTED TV STANDARDS AND RESOLUTIONS +-------------------------------------- + +The following TV standards are natively supported by the hardware and are +usable as (for example) the "norm=" parameter in the mplayer command: + + PAL_BGHIN, NTSC_N_443, + PAL_Nc, NTSC_N, + SECAM, NTSC_M, NTSC_M_JP, + PAL_60, NTSC_443, + PAL_M. + +The available picture sizes are: + + at 25 frames per second: 720x576, 704x576, 640x480, 360x288, 320x240; + at 30 frames per second: 720x480, 640x480, 360x240, 320x240; + + +WHAT'S TESTED AND WHAT'S NOT +---------------------------- + +This driver is known to work with mplayer, mencoder, tvtime and sufficiently +recent versions of vlc. An interface to ffmpeg is implemented, but serious +audio-video synchronization problems remain. + +The driver is designed to support all the TV standards accepted by the +hardware, but as yet it has actually been tested on only a few of these. + +I have been unable to test and calibrate the S-video input myself because I +do not possess any equipment with S-video output. + +This driver does not understand the V4L1 IOCTL commands, so programs such +as camorama are not compatible. There are reports that the driver does +work with sufficiently recent (V4L2) versions of zoneminder, but I have not +attempted to confirm this myself. + + +UDEV RULES +---------- + +In order that the special files /dev/easycap0 and /dev/easysnd1 are created +with conveniently relaxed permissions when the EasyCAP is plugged in, a file +is preferably to be provided in directory /etc/udev/rules.d with content: + +ACTION!="add|change", GOTO="easycap_rules_end" +ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \ + MODE="0666", OWNER="root", GROUP="root" +LABEL="easycap_rules_end" + + +ACKNOWLEGEMENTS AND REFERENCES +------------------------------ +This driver makes use of information contained in the Syntek Semicon DC-1125 +Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/ +by Nicolas Vivien. Particularly useful has been a patch to the latter driver +provided by Ivor Hewitt in January 2009.

The older way involved creating of a new kobj and pid sysfs file under it, and sending signal using that pid. Now we communicate via rfkill to user-space UIM. Background: UIM is the user-space daemon which upon notification from ldisc driver, opens the tty, sets default baud and then installs (tiocsetd) the ldisc.

Now, we iterate over all the segments in an incoming bio which allows us to handle all kinds of I/O requests. ramzswap devices can still handle PAGE_SIZE aligned and multiple of PAGE_SIZE sized I/O requests only. To ensure that we get always get such requests only, we set following request_queue attributes to PAGE_SIZE: - physical_block_size - logical_block_size - io_min - io_opt Note: physical and logical block sizes were already set equal to PAGE_SIZE and that seems to be sufficient to get PAGE_SIZE aligned I/O. Since we are no longer limited to handling swap requests only, the next few patches rename ramzswap to zram. So, the devices will then be called /dev/zram{0, 1, 2, ...} Usage/Examples: 1) Use as /tmp storage - mkfs.ext4 /dev/zram0 - mount /dev/zram0 /tmp 2) Use as swap: - mkswap /dev/zram0 - swapon /dev/zram0 -p 10 # give highest priority to zram0 Performance: - I/O benchamark done with 'dd' command. Details can be found here: http://code.google.com/p/compcache/wiki/zramperf Summary: - Maximum read speed (approx): - ram disk: 1200 MB/sec - zram disk: 600 MB/sec - Maximum write speed (approx): - ram disk: 500 MB/sec - zram disk: 160 MB/sec Issues: - Double caching: We can potentially waste memory by having two copies of a page -- one in page cache (uncompress) and second in the device memory (compressed). However, during reclaim, clean page cache pages are quickly freed, so this does not seem to be a big problem. - Stale data: Not all filesystems support issuing 'discard' requests to underlying block devices. So, if such filesystems are used over zram devices, we can accumulate lot of stale data in memory. Even for filesystems to do support discard (example, ext4), we need to see how effective it is. - Scalability: There is only one (per-device) de/compression buffer stats. This can lead to significant contention, especially when used for generic (non-swap) purposes.

Some Notes: - This patch moves the driver wholesale from wext to cfg80211. Wext support is still provided through the cfg80211 provided wext compatability layer. - Currently only infrastructure mode is implemented. Ad hoc mode is not yet implemented, but can be added. - It does not support connecting to a specified bssid, instead roaming is handled by the card itself. This matches the behaviour of the existing driver. - It has been tested using NetworkManager (via wpa_supplicant) configured to use the wext compatability layer, and then again with the native nl80211 layer.

As we have some files which aren't essential and are lists or tables aggregated from data from different places inside batman-adv, we must place them in a filesystem without such a restriction.

This should avoid problems with the sequence number sliding window algorithm which we had seen in the past for broadcast floods or malicious packet injections. We can not assure 100% security with this patch, but it is quite an improvement over the old 16 bit sequence numbers: * expected window size can be increased (4096 -> 65536) * 64k packets in the right order would now be needed to cause a loop, which seems practically impossible. Furthermore, a TTL field has been added to the broadcast packet type, just to make sure. These changes required to increase the compatibility level once again.

As we are able to route the payload traffic as we want, we may use multiple interfaces on multihomed hosts to transfer data to achieve higher bandwidth. This can be considered as "light Multi Path Routing" for single hop connections. To detect which interfaces of a peer node belong to the same host, a new flag PRIMARIES_FIRST_HOP is introduced. This flag is set on the first hop of OGMs of the primary (first) interface, which is broadcasted on all interfaces. When receiving such an OGM, we can learn which interfaces belong to the same host (by assigning them to the primary originator). Bonding works by sending packets in a round-robin fashion to the available interfaces of a neighbor host, if multiple interfaces are available. The neighbor interfaces should be almost equally good to reach. To avoid interferences (i.e. sending on the same channel), only neighbor interfaces with different mac addresses and different outgoing interfaces are considered as candidates. Bonding is deactivated by default, and can be activated by echo 1 > /sys/class/net/bat0/mesh/bonding for each individual node.

By default, we now try to avoid forwarding packets on the receiving interface, instead choosing alternative interfaces. This feature works only on nodes which have multiple interfaces connected to the mesh. This approach should reduce problems of the half-duplex nature of WiFi Hardware and thus increase performance.

This patch introduces comparable functionality for batman-adv ICMP messages. The patch adds a second batman ICMP packet format (icmp_packet_rr) such that up to 17 MAC addresses can be recorded (sufficient for up to 8 hops per direction). When no RR is wanted, the old icmp_packet without the RR overhead can be sent.
