drm/amdgpu: switch gtt_mgr to counting used pages

2021-06-23T18:59:39+00:00

Change mgr->available into mgr->used (invert the value).

Makes more sense to do it this way since we don't need the spinlock any
more to double check the handling.

v3 (chk): separated from the TEMPOARAY FLAG change.

drm/amdgpu: introduce a stolen reserved buffer to protect specific buffer region (v2)

2021-06-04T20:03:12+00:00

Some ASICs such as Yellow Carp needs to reserve a region of video memory
to avoid access from driver. So this patch is to introduce a stolen
reserved buffer to protect specific buffer region.

v2: free this buffer in amdgpu_ttm_fini.

drm/amdgpu: Implement mmap as GEM object function

2021-05-26T18:56:23+00:00

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.

This change resolves several inconsistencies between regular mmap and
prime-based mmap. The vm_ops field in vma is now set for all mmap'ed
areas. Previously it way only set for regular mmap calls, prime-based
mmap used TTM's default vm_ops. The function amdgpu_verify_access() is
no longer being called and therefore removed by this patch.

As a side effect, amdgpu_ttm_vm_ops and amdgpu_ttm_fault() are now
implemented in amdgpu's GEM code.

v4:
	* rebased
v3:
	* rename mmap function to amdgpu_gem_object_mmap() (Christian)
	* remove unnecessary checks from mmap (Christian)
v2:
	* rename amdgpu_ttm_vm_ops and amdgpu_ttm_fault() to
	  amdgpu_gem_vm_ops and amdgpu_gem_fault() (Christian)
	* the check for kfd_bo has meanwhile been removed

drm/amdgpu: Add new placement for preemptible SG BOs

2021-05-21T21:59:59+00:00

SG BOs such as dmabuf imports and userptr BOs do not consume system
resources directly. Instead they point to resources owned elsewhere.
They typically get evicted by DMABuf move notifiers of MMU notifiers.
If those notifiers don't need to wait for hardware fences (i.e. the SG
BOs are used in a preemptible context), then we don't need to limit
them to the GTT size and we don't need TTM to evict them.

Create a new placement for such preemptible SG BOs that does not impose
artificial size limits and TTM evictions.

drm/amdgpu: Use iterator methods exposed by amdgpu_res_cursor.h in building SG_TABLE's for a VRAM BO

2021-04-15T20:32:44+00:00

Extend current implementation of SG_TABLE construction method to
allow exportation of sub-buffers of a VRAM BO. This capability will
enable logical partitioning of a VRAM BO into multiple non-overlapping
sub-buffers. One example of this use case is to partition a VRAM BO
into two sub-buffers, one for SRC and another for DST.

drm/amdgpu: revert "reserve backup pages for bad page retirment"

2021-03-24T03:40:06+00:00

As noted during the review this approach doesn't make sense at all.

We should not apply any limitation on the VRAM applications can use inside the kernel.

If an application or end user wants to reserve a certain amount of VRAM for bad pages handling we should do this in the upper layer.

This reverts commit f89b881c81d9a6481fc17b46b351ca38f5dd6f3a.
