A few fixes for 4.14. Nothing too major.

drm/amdgpu: revert "fix deadlock of reservation between cs and gpu reset v2"

2017-09-13T02:16:31Z

This reverts commit 10e709cb296c98424c03408d23e3addeddcd4088. The patch doesn't work at all: 1. The CS can still be blocked because of amdgpu_ctx_add_fence(). 2. The order of submission isn't correct any more. 3. We could end up using freed up memory because we now drop the ctx reference to early. This needs to be fixed cleanly by doing the context handling after the BO handling, but this is a larger task just avoid the obvious crashes for now.

drm/syncobj: Rename fence_get to find_fence

2017-08-28T20:17:37Z

The function has far more in common with drm_syncobj_find than with any in the get/put functions. Signed-off-by: Jason Ekstrand Acked-by: Christian König (v1) Signed-off-by: Dave Airlie

drm/amdgpu: check memory allocation failure

2017-08-24T18:27:43Z

Check memory allocation failure and return -ENOMEM in such a case. 'num_post_dep_syncobjs' still has to be set to 0 before the test in order to have it initialized if 'amdgpu_cs_parser_fini()' is called to free resources. The calling graph would be, in such a case! failure in amdgpu_cs_process_syncobj_out_dep() ---> error code returned by amdgpu_cs_dependencies() --> amdgpu_cs_parser_fini() is called Reviewed-by: Christian König Signed-off-by: Christophe JAILLET Signed-off-by: Alex Deucher

drm/amdgpu: rename VM invalidated to moved

drm/amdgpu: move vram usage tracking into the vram manager v2

Looks like a better place for this. v2: use atomic64_t members instead Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: only move VM BOs in the LRU during validation v2

2017-08-17T19:45:57Z

This should save us a bunch of command submission overhead. v2: move the LRU move to the right place to avoid the move for the root BO and handle the shadow BOs as well. This turned out to be a bug fix because the move needs to happen before the kmap. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Acked-by: Chunming Zhou Signed-off-by: Alex Deucher
