| | * [POWERPC] cell: fix spurious false return from spu_trap_data_{map,seg}Andre Detsch2008-02-203-17/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, the __spufs_trap_data_map and __spu_trap_data_seq functions exit if spu->flags has the SPU_CONTEXT_SWITCH_ACTIVE set. This was resulting in suprious returns from these functions, as they may be legitimately called when we have this bit set. We only use it in these two sanity checks, so this change removes the flag completely. This fixes hangs in the page-fault path of SPE apps.

| | * [POWERPC] spufs: fix scheduler starvation by idle contextsJeremy Kerr2008-02-192-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.25 has a regression where we can starve the scheduler by creating (N_SPES+1) contexts, then running them one at a time. The final context will never be run, as the other contexts are loaded on the SPEs, none of which are repoted as free (ie, spu->alloc_state != SPU_FREE), so spu_get_idle() doesn't give us a spu to run on. Because all of the contexts are stopped, none are descheduled by the scheduler tick, as spusched_tick returns if spu_stopped(ctx). This change replaces the spu_stopped() check with checking for SCHED_IDLE in ctx->policy. We set a context's policy to SCHED_IDLE when we're not in spu_run(). We also favour SCHED_IDLE contexts when looking for contexts to unbind, but leave their timeslice intact for later resumption. This patch fixes the following test in the spufs-testsuite: tests/20-scheduler/02-yield-starvation Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

This does not allow for the case where #size-cells and/or #address-cells = 2 on a 32-bit system, as it will end up reading 32 bits instead of the expected 64.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Noted by various people (Sam, Jeff, Roland..) Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the tree as a empty file, and would cause git to correctly complain about a tracked file being removed after a "make distclean" (which removes empty files as garbage). And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around containing just a single newline.

There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

This patch fixes the bug.

This fixes the WARN_ON() reported by Laurent Riffard who was also very helpful in diagnosing the issue.
