* | slab allocators: Remove SLAB_DEBUG_INITIAL flagChristoph Lameter2007-05-07
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

* | [POWERPC] spufs: make spu page faults not block schedulingArnd Bergmann2007-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, we have always entered the spu page fault handler with a mutex for the spu context held. This has multiple bad side-effects: - it becomes impossible to suspend the context during page faults - if an spu program attempts to access its own mmio areas through DMA, we get an immediate livelock when the nopage function tries to acquire the same mutex This patch makes the page fault logic operate on a struct spu_context instead of a struct spu, and moves it from spu_base.c to a new file fault.c inside of spufs. We now also need to copy the dar and dsisr contents of the last fault into the saved context to have it accessible in case we schedule out the context before activating the page fault handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For quite a while now spu state is protected by a simple mutex instead of the old rw_semaphore, and this means we can simplify the locking around spu_setup_isolated a lot. Instead of doing an spu_release before entering spu_setup_isolated and then calling the complicated spu_acquire_exclusive we can now simply enter the function locked an in guaranteed runnable state, so that the only bit of spu_acquire_exclusive that's left is the call to spu_unmap_mappings. Similarly there's no more need to unlock and reacquire the state_mutex when spu_setup_isolated is done, but we can always return with the lock held and only drop it in spu_run_init in the failure case.

| * [POWERPC] Fix spu SLB invalidationsBenjamin Herrenschmidt2007-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* [POWERPC] spu sched: static timeslicing for SCHED_RR contextsChristoph Hellwig2007-02-13
| | | | | | | | | | | | | | | | | | | | | | | For SCHED_RR tasks we can do some really trivial timeslicing. Basically we fire up a time for every scheduler tick that searches for a higher or same priority thread that is on the runqueue and if there is one context switches to it. Because we can't lock spus from timer context we actually run this from a delayed runqueue instead of a timer. A nice optimization would be to skip the actual priority bitmap search when there are less contexts than physical spus available. To implement this I need a so far unpublished patch from Andre, and it will be added after we have that patch in. Note that right now we only do the time slicing for SCHED_RR tasks. The code would work for SCHED_OTHER tasks aswell, but their prio value is defered from the one the PPU thread has at time of spu_run, and using this for spu scheduling decisions would make the code very unfair. SCHED_OTHER support will be enabled once we the spu scheduler knows how to calculcate cpu_context.prio (very soon) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
