* gpu: nvgpu: Cancel timeout handler before job cleanupTerje Bergstrom2016-09-30

* gpu: nvgpu: fix allocation and map size mismatch while mappingDeepak Nibade2016-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to allocate larger size than user requested e.g. If we allocate at 64k granularity, and user asks for 32k buffer, we end up allocating 64k chunk. User still asks to map the buffer with size 32k and hence we reserve mapping addresses only for 32k But due to bug in mapping in update_gmmu_ptes_locked() we end up creating mappings considering size of 64k and corrupt some mappings Fix this by considering min(chunk->length, map_size) while mapping address range for a chunk Also, map_size will be zero once we map all requested address range. So bail out from the loop if map_size is zero Bug 1805064 Change-Id: I125d3ce261684dce7e679f9cb39198664f8937c4 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1217755 (cherry picked from commit 3ee1c6bc0718fb8dd9a28a37eff43a2872bdd5c0) Reviewed-on: http://git-master/r/1221775 GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

| | | | | | | | | | | | | | | | | | Fix the rmb() location of the rmb() in the buddy and bitmap allocators. The previous fix was not quite right. The rmb() needs to be after the init value is read so that any subsequent reads occur after the init value is read. If this is not done then subsequent reads could be loaded before the value of init is checked and possibly be invalid.

* gpu: nvgpu: test free user vidmem atomicallyKonsta Holtta2016-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | An empty list of soon-to-be-freed userspace vidmem buffers is not enough to safely assume that an allocation may succeed or not if tried again, because removal from the list and actually marking the memory freed is not atomic. Fix this by using an atomic counter for the number of pending frees (so that it's still safe to first remove from the job list and then perform the free), and making allocation attempts combined with a test of pending frees atomic. This still does not guarantee that there is memory available (as the actual amount of pending memory in bytes plus the current free amount isn't computed), but removes the race that produces false negatives in case a single program expects repeated frees and allocs to succeed.
