Subject: [PATCH 00/18] shadow page table support V3
Date: Fri, 12 Aug 2016 14:38:49 +0800 [thread overview]
Message-ID: <1470983947-32579-1-git-send-email-David1.Zhou@amd.com> (raw)
Since we cannot ensure VRAM is consistent after a GPU reset, page
table shadowing is necessary. Shadowed page tables are, in a sense, a
method to recover the consistent state of the page tables before the
reset occurred.
We need to allocate GTT bo as the shadow of VRAM bo when creating page table,
and make them the same. After gpu reset, we will need to use SDMA to copy GTT bo
content to VRAM bo, then page table will be recoveried.
V2:
Shadow bo uses a shadow entity running on normal run queue, after gpu reset,
we need to wait for all shadow jobs finished first, then recovery page table from shadow.
V3:
Addressed Christian comments for shadow bo part.
Chunming Zhou (18):
drm/amdgpu: add shadow bo support V2
drm/amdgpu: validate shadow as well when validating bo
drm/amdgpu: allocate shadow for pd/pt bo V2
drm/amdgpu: add shadow flag V2
drm/amdgpu: sync bo and shadow
drm/amdgpu: implement vm recovery function from shadow
drm/amdgpu: add shadow_entity for shadow page table updates
drm/amdgpu: update pd shadow bo
drm/amdgpu: update pt shadow
drm/amd: add last fence in sched entity
drm/amdgpu: link all vm clients
drm/amdgpu: add vm_list_lock

drm/amdgpu: add shadow fence owner
drm/amd: block entity
drm/amdgpu: recover page tables after gpu reset
drm/amdgpu: add need backup function
drm/amdgpu: add backup condition for vm
