* avr32: Fix bug in early resource allocation codeHaavard Skinnemoen2008-03-27
| | | | | | | | | | | | add_reserved_region() tries to keep the resource list sorted, so when looking for a place to insert the new resource, it may break out before the last entry. When this happens, the list is broken in two because the sibling field of the new entry doesn't point to the next resource. Fix it by updating the new resource's sibling field appropriately.

* avr32: Fix OCD refcounting bugHaavard Skinnemoen2008-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | Iff the parent has TIF_DEBUG set, _and_ clone_flags includes CLONE_PTRACE we should set the TIF_DEBUG flag for the child and increment the ocd refcount. Otherwise, the TIF_DEBUG flag must be unset. Currently, the child inherits TIF_DEBUG from the parent before copy_thread is called, so TIF_DEBUG may be already be set before we determine whether the child is supposed to inherit debugging capabilities from the parent or not. This means that ocd_enable() won't increment the refcount, because TIF_DEBUG is already set, and that TIF_DEBUG will be set for processes that aren't being debugged. This leads to a refcounting asymmetry, which may show up as ------------[ cut here ]------------ Badness at arch/avr32/kernel/ocd.c:73 PC is at ocd_disable+0x34/0x60 LR is at put_lock_stats+0xa/0x20 as reported by David Brownell.

* avr32: Call tick_nohz_{stop,restart}_sched_tick() in idle loopHaavard Skinnemoen2008-02-15
| | | | | | | | | | | | This fixes a hang on boot with nohz enabled. nohz is not actually supported in mainline yet, but patches that add support for it are currently under review. When nohz is compiled out, the functions are no-ops, so this patch results in no functional change, but it arguably makes the code more correct.

* Introduce flags for reserve_bootmem()Bernhard Walle2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | 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 Brownell2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [AVR32] Follow the rules when dealing with the OCD systemHaavard Skinnemoen2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Skinnemoen2007-12-07

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>
