* Basic PWM driver for AVR32 and AT91David Brownell2008-02-081-0/+54
| | | | | | | | | | | | | | | PWM device setup, and a simple PWM driver exposing a programming interface giving access to each channel's full capabilities. Note that this doesn't support starting several channels in synch.

* libfs: allow error return from simple attributesChristoph Hellwig2008-02-081-7/+11
| | | | | | | | | | | | | | | | | Sometimes simple attributes might need to return an error, e.g. for acquiring a mutex interruptibly. In fact we have that situation in spufs already which is the original user of the simple attributes. This patch merged the temporarily forked attributes in spufs back into the main ones and allows to return errors.

* Introduce flags for reserve_bootmem()Bernhard Walle2008-02-071-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

* gpiolib: avr32 at32ap platform supportDavid Brownell2008-02-053-81/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach AVR32 to use the "GPIO Library" when exposing its GPIOs, so that signals on external chips (like GPIO expanders) can easily be used. This mostly reorganizes some existing logic, with two minor changes in behavior: - The PSR registers are used instead of the previous "gpio_mask" values, matching AT91 behavior and removing some duplication between that role and that of "pinmux_mask". - NR_IRQs grew to acommodate a bank of external GPIOs. Eventually this number should probably become a board-specific config option. There's a debugfs dump of status for the built-in GPIOs, showing which pins have deglitching, pullups, or open drain drive enabled, as well as the ID string used when requesting each IRQ.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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>
* [AVR32] Follow the rules when dealing with the OCD systemHaavard Skinnemoen2007-12-074-227/+323
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [AVR32] Clean up OCD register usageHaavard Skinnemoen2007-12-075-33/+35

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>

* typo fixesMatt LaPlante2007-10-201-1/+1
| | | | | | | | | | | | Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

* pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn2007-10-192-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
