* gpu: nvgpu: support suspend/resume with user disabled railgatingDeepak Nibade2016-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We take an extra power refcount when we disable railgating through railgate_enable sysfs And that breaks suspend/resume since we check for power refcount first in gk20a_pm_suspend() Fix this with following : - set a flag user_railgate_disabled when User disables railgating through sysfs railgate_enable - in gk20a_pm_suspend(), drop one power refcount if flag is set - in gk20a_pm_resume(), take one refcount again if flag is set Fix __gk20a_do_idle() to consider this extra refcount as well. Add new variable target_ref_cnt and use it instead of assuming target refcount of 1 In case User has disabled rail gating, set this target refcount as 2 Also, export gk20a_idle_nosuspend() which drop power refcount without triggering suspend Bug 200233570 Change-Id: Ic0e35c73eb74ffefea1cd90d1b152650d9d2043d Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1236047 (cherry picked from commit 6e002d57da4b5c58ed79889728bb678d3aa1f1b1) Reviewed-on: http://git-master/r/1235219 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: allow skipping pramin barriersKonsta Holtta2016-10-17
| | | | | | | | | | | | | | | | | | | | | A wmb() next to each gk20a_mem_wr32() via PRAMIN may be overly careful, so support not inserting these barriers for performance, in cases where they are not necessary, where the caller would do an explicit barrier after a bunch of reads. Also, move those optional wmb()s to be done at the end of the whole internally batched write for gk20a_mem_{wr_n,memset} from the per-batch subloops that may run multiple times.

| | | | | | | | | | | | | | | | | | | | | | The lowest page table level may hold very few entries for mappings of large pages, but a new page is allocated for each list of entries at the lowest level, wasting memory and performance. Compact these so that the new "allocation" of ptes is appended at the end of the previous allocation, if there is space. 4 KB page is still the smallest size requested from the allocator; any possible overhead in the allocator (e.g., internally allocating big pages only) is not taken into account.

* 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.
