amdgpu: fix multi-process hang issue

2018-08-22T21:05:20Z

SWDEV-146499: hang during multi vulkan process testing cause: the second frame's PREAMBLE_IB have clear-state and LOAD actions, those actions ruin the pipeline that is still doing process in the previous frame's work-load IB. fix: need insert pipeline sync if have context switch for SRIOV (because only SRIOV will report PREEMPTION flag to UMD) Signed-off-by: Monk Liu Signed-off-by: Emily Deng Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: remove fence context from the job

drm/amdgpu: fix user fence write race condition

2018-07-05T21:39:57Z

The buffer object backing the user fence is reserved using the non-user fence, i.e., as soon as the non-user fence is signaled, the user fence buffer object can be moved or even destroyed. Therefore, emit the user fence first. Both fences have the same cache invalidation behavior, so this should have no user-visible effect.

drm/amdgpu: enable vcn jpeg ib test

drm/amdgpu: optionally do a writeback but don't invalidate TC for IB fences

2018-05-15T18:43:32Z

There is a new IB flag that enables this new behavior. Full invalidation is unnecessary for RELEASE_MEM and doesn't make sense when draw calls from two adjacent gfx IBs run in parallel. This will be the new default for Mesa. v2: bump the version Signed-off-by: Marek Olšák Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: cleanup SA inti and fini(v2)

2018-02-28T19:18:07Z

should use bo_create_kernel instead of split to two function that create and pin the SA bo issue: before this patch, there are DMAR read error in host side when running SRIOV test, the DMAR address dropped in the range of SA bo. fix: after this cleanups of SA init and fini, above DMAR eror gone. v2: keep sa_bo's fini instead of suspend, to keep reporting error Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: adjust timeout for ib_ring_tests(v2)

2018-02-28T19:18:07Z

issue: sometime GFX/MM ib test hit timeout under SRIOV env, root cause is that engine doesn't come back soon enough so the current IB test considered as timed out. fix: for SRIOV GFX IB test wait time need to be expanded a lot during SRIOV runtimei mode since it couldn't really begin before GFX engine come back. for SRIOV MM IB test it always need more time since MM scheduling is not go together with GFX engine, it is controled by h/w MM scheduler so no matter runtime or exclusive mode MM IB test always need more time. v2: use ring type instead of idx to judge Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: cond_exec only for schedule with a job

2018-02-28T19:18:04Z

issue: under SR-IOV sometimes the iB test will fail on gfx ring fix: with cond_exec inserted in RB the gfx engine would skip part packets if RLCV issue PREEMPT on gfx engine if gfx engine is prior to COND_EXEC packet, this is okay for regular command from UMD, but for the ib test since the whole dma format doesn't support PREEMPT so must remove the COND_EXEC from it.
