2008-02-04kbuild: Fix instrumentation removal breakage on avr32Haavard Skinnemoen
AVR32 still includes Kconfig.instrumentation, so it won't build after this... Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-02-03Add HAVE_KPROBESMathieu Desnoyers
Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config KPROBES_SUPPORT def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... - Use HAVE_KPROBES - Use a select - Yet another update : Moving to HAVE_* now. - Update ARM for kprobes support.

2008-01-25[AVR32] extint: Set initial irq type to low levelHaavard Skinnemoen
David Brownell pointed out a mismatch in the avr32 extint code: > I noticed a small glitch that's not fixed by this patch: the > initial type is falling edge, but IRQ_TYPE_NONE is mapped to > IRQ_TYPE_LEVEL_LOW. Potentially surprising. Fix it by setting the initial type (and handler) to low level, matching the meaning of IRQ_TYPE_NONE. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2008-01-25[AVR32] Add support for AT32AP7001 and AT32AP7002Haavard Skinnemoen
These are derivatives of the AT32AP7000 chip, which means that most of the code stays the same. Rename a few files, functions, definitions and config symbols to reflect that they apply to all AP700x chips, and exclude some platform devices from chips where they aren't present. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2008-01-25[AVR32] Provide more CPU information in /proc/cpuinfo and dmesgHaavard Skinnemoen
Add the following fields to /proc/cpuinfo: * chip type and revision (from the JTAG chip id) * cpu MHz (from clk_get_rate()) * features (from the CONFIG0 register) Also rename "cpu family" to "cpu arch" and "cpu type" to "cpu core" to remove some ambiguity. Show chip type and revision at bootup, and clarify that the other kinds of IDs that we're already printing are for the cpu core and architecture. Rename "AP7000" to "AP7" since that's the name of the core. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2008-01-25[AVR32] Enable debugging only when neededHaavard Skinnemoen
Keep track of processes being debugged (including the kernel itself) and turn the OCD system on and off as appropriate. Since enabling debugging turns off some optimizations in the CPU core, this fixes the issue that enabling KProbes support or simply running a program under gdbserver will reduce system performance significantly until the next reboot. The CPU performance will still be reduced for all processes while a process is being debugged, but this is a lot better than reducing the performance forever.

2008-01-25[AVR32] Remove redundant try_to_freeze() call from do_signal()Haavard Skinnemoen
get_signal_to_deliver() will call try_to_freeze(), so there's no point in do_signal() doing it as well. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2008-01-25[AVR32] Drop GFP_COMP for DMA memory allocationsHaavard Skinnemoen
dma_alloc_coherent wants to split pages after allocation in order to reduce the memory footprint. This does not work well with GFP_COMP pages, so drop this flag before allocation. This patch was forward-ported from BSP 2.0 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2008-01-24Driver core: change sysdev classes to use dynamic kobject namesKay Sievers

2007-12-07[AVR32] Fix wrong pt_regs in critical exception handlerHaavard Skinnemoen
It's not like it really matters at this point since the system is dying anyway, but handle_critical pushes too few registers on the stack so the register dump, which makes the register dump look a bit strange. This patch fixes it. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-12-07[AVR32] Fix copy_to_user_page() breakageHaavard Skinnemoen
The current implementation of copy_to_user_page() gives "vaddr" to the cache instruction when trying to sync the icache with the dcache. If vaddr does not exist in the TLB, the CPU will silently abort the operation, which may result in the caches staying out of sync. To fix this, pass the "dst" parameter to flush_icache_range() instead -- we know this is valid because we just wrote to it. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-12-07[AVR32] Follow the rules when dealing with the OCD systemHaavard Skinnemoen
The current debug trap handling code does a number of things that are illegal according to the AVR32 Architecture manual. Most importantly, it may try to schedule from Debug Mode, thus clearing the D bit, which can lead to "undefined behaviour". It seems like this works in most cases, but several people have observed somewhat unstable behaviour when debugging programs, including soft lockups. So there's definitely something which is not right with the existing code. The new code will never schedule from Debug mode, it will always exit Debug mode with a "retd" instruction, and if something not running in Debug mode needs to do something debug-related (like doing a single step), it will enter debug mode through a "breakpoint" instruction. The monitor code will then return directly to user space, bypassing its own saved registers if necessary (since we don't actually care about the trapped context, only the one that came before.) This adds three instructions to the common exception handling code, including one branch. It does not touch super-hot paths like the TLB miss handler.

2007-12-07[AVR32] Clean up OCD register usageHaavard Skinnemoen
Generate a new set of OCD register definitions in asm/ocd.h and rename __mfdr() and __mtdr() to ocd_read() and ocd_write() respectively. The bitfield definitions are a lot more complete now, and they are entirely based on bit numbers, not masks. This is because OCD registers are frequently accessed from assembly code, where bit numbers are a lot more useful (can be fed directly to sbr, bfins, etc.) Bitfields that consist of more than one bit have two definitions: _START, which indicates the number of the first bit, and _SIZE, which indicates the number of bits. These directly correspond to the parameters taken by the bfextu, bfexts and bfins instructions. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-11-15[AVR32] Export intc_get_pending symbolHaavard Skinnemoen

Separate out most of the at32_add_device_ide() code and use it to implement at32_add_device_cf() as well. This changes the API in the following ways: * The board code must initialize data->cs to the chipselect ID to use before calling any of these functions. * The board code must use GPIO_PIN_NONE to indicate unused CF pins.

2007-10-19pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn
is_init() is an ambiguous name for the pid==1 check. Split it into is_global_init() and is_container_init(). A cgroup init has it's tsk->pid == 1. A global init also has it's tsk->pid == 1 and it's active pid namespace is the init_pid_ns. But rather than check the active pid namespace, compare the task structure with 'init_pid_ns.child_reaper', which is initialized during boot to the /sbin/init process and never changes. Changelog: 2.6.22-rc4-mm2-pidns1: - Use 'init_pid_ns.child_reaper' to determine if a given task is the global init (/sbin/init) process. This would improve performance and remove dependence on the task_pid(). 2.6.21-mm2-pidns2: - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc, ppc,avr32}/traps.c for the _exception() call to is_global_init(). This way, we kill only the cgroup if the cgroup's init has a bug rather than force a kernel panic.

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync.

2007-10-16During VM oom condition, kill all threads in process groupWill Schmidt
We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or be otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread.
