From f00a75c094c340c4e7435665816c3273c870e849 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 5 Oct 2009 15:17:45 +0100 Subject: ARM: Pass VMA to copy_user_highpage() implementations Our copy_user_highpage() implementations may require cache maintainence. Ensure that implementations have all necessary details to perform this maintainence.

Resolve this by flushing the user mapping before copying the page on processors with a writeback VIVT cache. Note: this does have a performance impact, and so needs further consideration before being merged - can we optimize out some of the cache flushes if, eg, we know that the page isn't yet mapped?

Now that the return from alloc_percpu is compatible with the address of per-cpu vars, it makes sense to hand around the address of per-cpu variables. To make this sane, we remove the per_cpu__ prefix we used created to stop people accidentally using these vars directly. Now we have sparse, we can use that (next patch). tj: * Updated to convert stuff which were missed by or added after the original patch. * Kill per_cpu_var() macro.

This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

Unlike MIPS, SH follows the convention that all structures in the page table (pgd_t, pmd_t, pgprot_t, etc) must be the same size. Therefore, 64-bit PTEs require 64-bit PGD entries, etc. Using 2-levels of page tables and 64-bit PTEs it is only possible to map 1GB of virtual address space. In order to map all 4GB of virtual address space we need to adopt a 3-level page table layout. This actually works out better for CONFIG_SUPERH32 because we only waste 2 PGD entries on the P1 and P2 areas (which are untranslated) instead of 256.

The memcpy() part of this is slightly subtle: while alternative instruction patching does itself use memcpy(), with the replacement block being less than 64-bytes in size the main loop of the original function doesn't get used for copying memcpy_c() over memcpy(), and hence we can safely write over its beginning. Also note that the CFI annotations are fine for both variants of each of the functions.

The problem was that pmd_offset() was returning an index of non-zero when it should have been returning 0.

Reclaim vectors 0x20-0x2f by reallocating the IRQ_MOVE_CLEANUP_VECTOR to vector 0x1f. This is in the range of vector numbers that is officially reserved for the CPU (for exceptions), however, the use of the APIC to generate any vector 0x10 or above is documented, and the CPU internally can receive any vector number (the legacy BIOS uses INT 0x08-0x0f for interrupts, as messed up as that is.) Since IRQ_MOVE_CLEANUP_VECTOR has to be alone in the lowest-numbered priority level (block of 16), this effectively enables us to reclaim an otherwise-unusable APIC priority level and put it to use. Since this is a transient kernel-only allocation we can change it at any time, and if/when there is an exception at vector 0x1f this assignment needs to be changed as part of OS enabling that new feature.

This is the next big chunk of hw_breakpoint support. This decouples the SH-4A support from the core and moves it out in to its own stub, following many of the conventions established with the perf events layering. In addition to extending SH-4A support to encapsulate the remainder of the UBC channels, clock framework support for handling the UBC interface clock is added as well, allowing for dynamic clock gating. This also fixes up a regression introduced by the SIGTRAP handling that broke the ksym_tracer, to the extent that the current support works well with all of the ksym_tracer/ptrace/kgdb. The kprobes singlestep code will follow in turn. With this in place, the remaining UBC variants (SH-2A and SH-4) can now be trivially plugged in.

As SH has a very sparse IRQ map by default, all new CPUs and boards benefit from using sparseirq by default. Despite this, there are still a few stragglers (mostly due to using a fixed IRQ range for their FPGA IRQ mappings), and these still need to be converted over one by one. As these are now in the minority, and we do not want to encourage this sort of brain-damage in newer board ports, we force sparseirq on.

This follows the x86 xstate changes and implements a task_xstate slab cache that is dynamically sized to match one of hard FP/soft FP/FPU-less. This also tidies up and consolidates some of the SH-2A/SH-4 FPU fragmentation. Now fpu state restorers are commonly defined, with the init_fpu()/fpu_init() mess reworked to follow the x86 convention. The fpu_init() register initialization has been replaced by xstate setup followed by writing out to hardware via the standard restore path. As init_fpu() now performs a slab allocation a secondary lighterweight restorer is also introduced for the context switch. In the future the DSP state will be rolled in here, too. More work remains for math emulation and the SH-5 FPU, which presently uses its own special (UP-only) interfaces.

So instead of using "(%%eax)" to specify the memory address that is the semaphore, we use "(%1)" or similar. And instead of forcing the operation to always be 32-bit, we use "%z0", taking the size from the actual semaphore data structure itself. This doesn't actually matter on x86-32, but if we want to use the same inline asm for x86-64, we'll need to have the compiler generate the proper 64-bit names for the registers (%rax instead of %eax), and if we want to use a 64-bit counter too (in order to avoid the 15-bit limit on the write counter that limits concurrent users to 32767 threads), we'll need to be able to generate instructions with "q" accesses rather than "l". Since this header currently isn't enabled on x86-64, none of that matters, but we do want to use the xadd version of the semaphores rather than have to take spinlocks to do a rwsem. The mm->mmap_sem can be heavily contended when you have lots of threads all taking page faults, and the fallback rwsem code that uses a spinlock performs abysmally badly in that case.

This introduces some much overdue chainsawing of the fixed PMB support. fixed PMB was introduced initially to work around the fact that dynamic PMB mode was relatively broken, though they were never intended to converge. The main areas where there are differences are whether the system is booted in 29-bit mode or 32-bit mode, and whether legacy mappings are to be preserved. Any system booting in true 32-bit mode will not care about legacy mappings, so these are roughly decoupled. Regardless of the entry point, PMB and 32BIT are directly related as far as the kernel is concerned, so we also switch back to having one select the other. With legacy mappings iterated through and applied in the initialization path it's now possible to finally merge the two implementations and permit dynamic remapping overtop of remaining entries regardless of whether boot mappings are crafted by hand or inherited from the boot loader.

The vast majority of the in-tree offenders are gone, with the only remaining culprits being unable to support 32-bit mode. Hopefully this will prevent anyone from ever using these again.

All SH-X2 and SH-X3 parts support an extended TLB mode, which has been left as experimental since support was originally merged. Now that it's had some time to stabilize and get some exposure to various platforms, we can drop it as an option and default enable it across the board. This is also good future proofing for newer parts that will drop support for the legacy TLB mode completely. This will also force 3-level page tables for all newer parts, which is necessary both for the varying page sizes and larger memories.

Based on the server workload, OSPM can request what frequency it expects from a logical CPU, and the BIOS will achieve that frequency transparently. This patch introduces driver support for PCC. OSPM uses the PCC driver to communicate with the BIOS via the PCC interface. There is a Documentation file that provides a link to the PCC Specification, and also provides a summary of the PCC interface. Currently, certain HP ProLiant platforms implement the PCC interface. However, any platform whose BIOS implements the PCC Specification, can utilize this driver. V2 --> V1 changes (based on Dominik's suggestions): - Removed the dependency on CPU_FREQ_TABLE - "cpufreq_stats" will no longer PANIC. Actually, it will not load anymore because it is not applicable. - Removed the sanity check for target frequency in the ->target routine. NOTE: A patch to sanitize the target frequency requested by "ondemand" is needed to ensure that the target freq < policy->min. Can this driver be queued up for the 2.6.33 tree?

We have "long", we have "__s32", and we have "int". To make it work on x86-64, the types suddenly matter a lot more. It can be either a 32-bit or 64-bit signed type, and both work (with the caveat that a 32-bit counter will only have 15 bits of effective write counters, so it's limited to 32767 users). But whatever type you choose, it needs to be used consistently. This makes a new 'rwsem_counter_t', that is a 32-bit signed type. For a 64-bit type, you'd need to also update the BIAS values.

So this really does need that whole "make rwsem_count_t be 64-bit and fix the BIAS values to match" extension on top of it, but that is conceptually a totally independent issue. NOT TESTED! The original patch that this all was based on were tested by KAMEZAWA Hiroyuki, but maybe I screwed up something when I created the cleaned-up series, so caveat emptor.. Also note that it _may_ be a good idea to mark some more registers clobbered on x86-64 in the inline asms instead of saving/restoring them. They are inline functions, but they are only used in places where there are not a lot of live registers _anyway_, so doing for example the clobbers of %r8-%r11 in the asm wouldn't make the fast-path code any worse, and would make the slow-path code smaller. (Not that the slow-path really matters to that degree. Saving a few unnecessary registers is the _least_ of our problems when we hit the slow path. The instruction/cycle counting really only matters in the fast path). Signed-off-by: Linus Torvalds LKML-Reference: Signed-off-by: H.

Tsirkin" Date: Thu, 14 Jan 2010 06:17:27 +0000 Subject: vhost_net: a kernel-level virtio server What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration, bug work-arounds in userspace) - write logging is supported (good for migration) - support memory table and not just an offset (needed for kvm) common virtio related code has been put in a separate file vhost.c and can be made into a separate module if/when more backends appear. I used Rusty's lguest.c as the source for developing this part : this supplied me with witty comments I wouldn't be able to write myself. What it is not: vhost net is not a bus, and not a generic new system call. No assumptions are made on how guest performs hypercalls. Userspace hypervisors are supported as well as kvm. How it works: Basically, we connect virtio frontend (configured by userspace) to a backend. The backend could be a network device, or a tap device. Backend is also configured by userspace, including vlan/mac etc. Status: This works for me, and I haven't see any crashes. Compared to userspace, people reported improved latency (as I save up to 4 system calls per packet), as well as better bandwidth and CPU utilization. Features that I plan to look at in the future: - mergeable buffers - zero copy - scalability tuning: figure out the best threading model to use Note on RCU usage (this is also documented in vhost.h, near private_pointer which is the value protected by this variant of RCU): what is happening is that the rcu_dereference() is being used in a workqueue item. The role of rcu_read_lock() is taken on by the start of execution of the workqueue item, of rcu_read_unlock() by the end of execution of the workqueue item, and of synchronize_rcu() by flush_workqueue()/flush_work(). In the future we might need to apply some gcc attribute or sparse annotation to the function passed to INIT_WORK(). Paul's ack below is for this RCU usage.

More and more boards are going to start shipping that boot with the MMU in 32BIT mode by default. Previously we relied on the bootloader to setup PMB mappings for use by the kernel but we also need to cater for boards whose bootloaders don't set them up. If CONFIG_PMB_LEGACY is not enabled we have full control over our PMB mappings and can compress our address space. Usually, the distance between the the cached and uncached mappings of RAM is always 512MB, however we can compress the distance to be the amount of RAM on the board. pmb_init() now becomes much simpler. It no longer has to calculate any mappings, it just has to synchronise the software PMB table with the hardware. Tested on SDK7786 and SH7785LCR.

Also we don't need to reserve the entire privilege level (all 16 vectors in the priority bucket that IRQ_MOVE_CLEANUP_VECTOR falls into), as the x86 architecture (section 10.9.3 in SDM Vol3a) specifies that with in the priority level, the higher the vector number the higher the priority. And hence we don't need to reserve the complete priority level 0x20-0x2f for the IRQ migration cleanup logic. So change the IRQ_MOVE_CLEANUP_VECTOR to 0x20 and allow 0x21-0x2f to be used for device interrupts. 0x30-0x3f will be used for ISA interrupts (these also can be migrated in the context of IOAPIC and hence need to be at a higher priority level than IRQ_MOVE_CLEANUP_VECTOR).

Change rwsem_count_t to a signed long, so that it is 64 bits on x86-64. This required the following changes to the assembly code: a) %z0 doesn't work on all versions of gcc! At least gcc 4.4.2 as shipped with Fedora 12 emits "ll" not "q" for 64 bits, even for integer operands. Newer gccs apparently do this correctly, but avoid this problem by using the _ASM_ macros instead of %z. b) 64 bits immediates are only allowed in "movq $imm,%reg" constructs... no others. Change some of the constraints to "e", and fix the one case where we would have had to use an invalid immediate -- in that case, we only care about the upper half anyway, so just access the upper half.

Presently 'flags' gets passed around a lot between the various ioremap helpers and implementations, which is only 32-bits. In the X2TLB case we use 64-bit pgprots which presently results in the upper 32bits being chopped off (which handily include our read/write/exec permissions). As such, we convert everything internally to using pgprot_t directly and simply convert over with pgprot_val() where needed. With this in place, transparent fixmap utilization for early ioremap works as expected.

If these IRQ's are handled by legacy pic controller, then the kernel handles them only on cpu 0. So there is no need to block this vector space on all cpu's. Similarly if these IRQ's are handled by IO-APIC, then the IRQ affinity will determine on which cpu's we need allocate the vector resource for that particular IRQ. This can be done dynamically and here also there is no need to block 16 vectors for IRQ0..IRQ15 on all cpu's. Fix this by initially assigning IRQ0..IRQ15 to IRQ0_VECTOR..IRQ15_VECTOR's only on cpu 0. If the legacy controllers like pic handles these irq's, then this configuration will be fixed. If more modern controllers like IO-APIC handle these IRQ's, then we start with this configuration and as IRQ's migrate, vectors (/and cpu's) associated with these IRQ's change dynamically. This will freeup the block of 16 vectors on other cpu's which don't handle IRQ0..IRQ15, which can now be used for other IRQ's that the particular cpu handle.

The total number of pages to unmap factored in the mapping offset and aligned up to the next page boundary, which doesn't match the ioremap_fixed() behaviour. When ioremap_fixed() pegs a slot, the address in the mapping data already contains the offset displacement, and the size is recorded verbatim given that we're only interested in total number of pages required. As such, we need to calculate the total number from the original size in the unmap path as well. At the same time, there was also an off-by-1 problem in the fixmap index calculation which has also been corrected. Previously subsequent remaps of an identical fixmap index would trigger the pte_ERROR() in set_pte_phys(): arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506). arch/sh/mm/init.c:77: bad pte 8053ffb0(0000781003fff506).

The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.

Hence we need to use absolute addresses to access the control registers. Some of the clock domains have modules falling in the address space of PRM partition.

Introduce a new CK_* flag, CK_3XXX, that marks all clocks that are common to OMAP3 family chips. CK_343X now refers to clocks that are available only on OMAP34{1,2,3,4}0 (WTBU) and OMAP35{03,15,25,30} (any version). At some point, the RATE_IN_* flags should be updated also. While here, add some documentation describing the chip families covered by these clock flags. This patch is partially based on patches from Ranjith Lohithakshan and Vishwanath Sripathy .

For the subsequent wakeup and sleep dependency usecounting patch to work, these can no longer be shared. This patch splits the shared structures apart.

In the current situation, if several functions add dependencies on the same clockdomains, when the first dependency removal function is called, the dependency will be incorrectly removed from the hardware. Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which provide a fast and usecounting-consistent way to clear all hardware clockdomain dependencies, since accesses to these registers can be quite slow. pm{2,3}4xx.c has been updated to use these new functions. The original version of this patch did not touch these files, which previously wrote directly to the wkdep registers, and thus confused the usecounting code. This problem was found by Kevin Hilman . N.B.: This patch introduces one significant functional difference over the previous pm34xx.c code: sleepdeps are now cleared during clockdomain initialization, whereas previously they were left untouched. This has been tested by Kevin and confirmed to work. The original version of this patch also did not take into consideration that some clockdomains do not have sleep or wakeup dependency sources, which caused NULL pointer dereferences. This problem was debugged and fixed by Kevin Hilman .

Here the worst-case measured latencies for the activate and deactivate hooks are stored. In addition, add an option to auto-adjust the latency values used for device activate/deactivate. By setting a new 'OMAP_DEVICE_LATENCY_AUTO_ADJUST' flag in the omap_device_pm_latency struct, the omap_device layer automatically adjusts the activate/deactivate latencies to the worst-case measured values. Anytime a new worst-case value is found, it is printed to the console. Here is an example log during boot using UART2 s an example. After boot, the OPP is manually changed to the 125MHz OPP: [...] Freeing init memory: 128K omap_device: serial8250.2: new worst case deactivate latency 0: 30517 omap_device: serial8250.2: new worst case activate latency 0: 30517 omap_device: serial8250.2: new worst case activate latency 0: 218139648 omap_device: serial8250.2: new worst case deactivate latency 0: 61035 omap_device: serial8250.2: new worst case activate latency 0: 278076171 omap_device: serial8250.2: new worst case activate latency 0: 298614501 omap_device: serial8250.2: new worst case activate latency 0: 327331542 / # echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed omap_device: serial8250.2: new worst case deactivate latency 0: 91552 Motivation: this can be used as a technique to automatically determine the worst case latency values. The current method of printing a warning on every violation is too noisy to actually interact the console in order to set low OPP to discover latencies. Another motivation for this patch is that the activate/deactivate latenices can vary depending on the idlemode of the device. While working on the UARTs, I noticed that when using no-idle, the activate latencies were as high as several hundred msecs as shown above. When the UARTs are in smart-idle, the max latency is well under 100 usecs.

This is intended to make the clock code easier to understand, since all of the functions needed to manage DPLLs are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for DPLLs alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be moved to the plat-omap/ directory to be shared. Thanks to Alexander Shishkin for his comments to improve the patch description.

This is intended to make the clock code easier to understand, since all of the functions needed to manage clksel clocks are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for clksel clocks alon. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be moved to the plat-omap/ directory to be shared. Thanks to Alexander Shishkin for his comments to improve the patch description.

This is intended to make the clock code easier to understand, since all of the functions needed to manage the OMAP2 DPLL+CORE clock are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for the DPLL+CORE clock alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type. Thanks to Alexander Shishkin for his comments to improve the patch description.

This is intended to make the clock code easier to understand, since all of the functions needed to manage the virt_prcm_set clock are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for the virt_prcm_set clock alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type. Thanks to Alexander Shishkin for his comments. Thanks also to Kevin Hilman for finding and fixing a bug with the CONFIG_CPU_FREQ portion of this patch.

Presently trapped I/O is only registered if it's not explicitly disabled for the platforms that select it openly. From the fault path this runs through an address lookup before figuring out that nothing matches and falls back through the error path, but we can forego the lookup completely by testing if it's been explicitly disabled. This provides a measurable speedup for things like qemu that rely on runtime disabling.

The VBR value needs to be initialized in order for any of the bios trapping to work, and as we don't do that until slightly later in the boot process, this has no real chance of working. The only reason for using this in the past was due to the fact that early serial initialization wasn't possible, but now that early sh-sci is supported by everyone, there's no longer any reason to support the sh_bios hacks in the first place. Given that, we just kill off the references completely.

There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely Acked-by: David S.

This is intended to make the clock code easier to understand, since all of the functions needed to manage APLLs are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for APLL clocks alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type.

This is intended to make the clock code easier to understand, since all of the functions needed to manage the OMAP3 DPLL3 M2 divider are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for the DPLL3 M2 clock alone. This should reduce unnecessary console noise when debugging DVFS. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap34xx/ directory, rather than shared with other chip types that don't use this clock type. This patch also lays the groundwork to skip compilation of this code on OMAP3 chips that don't support DVFS (e.g., AM35xx) via the Makefile, rather than via #ifdefs.

The algorithm takes into account the list of counter constraints for each event. It assigns events to counters from the most constrained, i.e., works on only one counter, to the least constrained, i.e., works on any counter. Intel Fixed counter events and the BTS special event are also handled via this algorithm which is designed to be fairly generic. The patch also updates the validation of an event to use the scheduling algorithm. This will cause early failure in perf_event_open(). The 2nd version of this patch follows the model used by PPC, by running the scheduling algorithm and the actual assignment separately. Actual assignment takes place in hw_perf_enable() whereas scheduling is implemented in hw_perf_group_sched_in() and x86_pmu_enable().

Instead define them as n. They can then be used as val << n. The changes are generated by updating the script which autogenerates the files modifed in the patch.

In the logical flat mode, once the AP's are online (and before irqbalance comes into picture), kernel intends to handle these IRQ's on any cpu (as the logical flat mode allows to specify multiple cpu's for the irq destination and the chipset based routing can deliver to the interrupt to any one of the specified cpu's). This was broken with our recent change, which was ending up using only cpu 0 as the destination, even when the kernel was specifying to use all online cpu's for the logical flat mode case. Fix this by updating vector allocation domain (cfg->domain) for legacy irqs, when the IO-APIC handles them.

For example, this behavior was observed on a P4 based system with SiS chipset which was reported by Li Zefan. We have been handling this kind of behavior by making sure that in logical flat mode, we assign the same vector to irq mappings on all the 8 possible logical cpu's. But we have been doing this initial assignment (__setup_vector_irq()) a little late (before which interrupts were already enabled for a short duration). Move the __setup_vector_irq() before the first irq enable point in the cpu online path to avoid the issue of not handling some interrupts that wrongly hit the cpu which is still coming online.

This adds some helper glue for scanning the bus and determining if all of the devices are 66MHz capable or not before flipping on 66MHz mode. This isn't quite to spec, but it's fairly consistent with what other embedded controllers end up having to do. Scanning code cribbed from the MIPS txx9 PCI code.

The SH7780 PCI controller supports 3 different ranges of PCI memory in addition to its PCI I/O window. In the case of 29-bit mode, only 2 memory windows are supported, while in 32-bit mode all 3 are visible. This attempts to make the resource handling completely dynamic and to permit platforms to map in as many apertures as they can handle.

Previously, the "cpu-release-addr" property contained a value referencing the boot page translation address range of 0xfffffxxx, which then indirectly accessed RAM. The "cpu-release-addr" is currently ioremapped and the secondary cores kicked. However, due to the recent change in "cpu-release-addr", it sometimes points to a memory location in low memory that cannot be ioremapped. For example on a P2020-based board with 512MB of RAM the following error occurs on bootup: <...> mpic: requesting IPIs ... __ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0 Unable to handle kernel paging request for data at address 0x00000014 Faulting instruction address: 0xc05df9b0 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 P2020 RDB Modules linked in: <... eventual kernel panic> Adding logic to conditionally ioremap or access memory directly resolves the issue.

A second patch follows that dynamically updates this for SMT. The second field just indicates that our OS is Linux, and not another OS.

However, that value isn't quite right for a system that supports multiple threads per core, thus permitting the firmware to assign more cores to a Linux partition than it can really cope with. This patch improves it by using the device-tree to determine the number of threads supported by the processors in order to adjust the value passed to firmware.

This patch provides checking routines for x86 smp alternatives and dynamic ftrace. Since both functions modify fixed pieces of kernel text, they should reserve and protect those from other dynamic text modifier, like kprobes. This will also be extended when introducing other subsystems which modify fixed pieces of kernel text. Dynamic text modifiers should avoid those.

The new part supports 1080p video and has the ARM running at 495MHz. More SoC information: http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html Spectrum Digital, Inc has a new EVM for this part. It is _mostly_ same as the older DM6467 EVM except for a 33MHz crystal input and THS8200 video encoder for 1080p support. The meat of this patch is dedicated to initializing the crystal frequency from EVM board file. Additional notes: I did consider some alternative ways to make the crystal input board specific including - (1) having board code initialize the crystal frequency using the first member of soc_info->cpu_clks array (2) introducing a new ref_clk_rate member in soc_info structure. But, the current way seems to be the simplest and least intruding considering that both the clock array and SoC info structure are actually private to the SoC file. Also the fact that davinci_common_init() initializes both the soc_info and clocks in one go.
