drm/amdgpu: Add early fini callback

2021-05-20T03:48:50Z

Use it to call disply code dependent on device->drv_data before it's set to NULL on device unplug v5: Move HW finilization into this callback to prevent MMIO accesses post cpi remove. v7: Split kfd suspend from device exit to expdite HW related stuff to amdgpu_pci_remove v8: Squash previous KFD commit into this commit to avoid compile break.

drm/amdkfd: heavy-weight flush TLB after unmap

2021-05-20T02:37:50Z

Need do a heavy-weight TLB flush to make sure we have no more dirty data in the cache for the unmapped pages. Define enum TLB_FLUSH_TYPE, add flush_type parameter to amdgpu_amdkfd_flush_gpu_tlb_pasid.

drm/amdgpu: use amdgpu_bo_user bo for metadata and tiling flag

2021-04-09T20:45:31Z

Tiling flag and metadata are only needed for BOs created by amdgpu_gem_object_create(), so we can remove those from the base class. v2: * squash tiling_flags and metadata relared patches into one * use BUG_ON for non ttm_bo_type_device type when accessing tiling_flags and metadata._ v3: *include to_amdgpu_bo_user Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Use free system memory size for kfd memory accounting

2021-03-24T02:57:49Z

With the current kfd memory accounting scheme, kfd applications can use up to 15/16 of total system memory. For system which has small total system memory size it leaves small system memory for OS. For example, if the system has totally 16GB of system memory, this scheme leave OS and non-kfd applications only 1GB of system memory. In many cases, this leads to OOM killer. This patch changed the KFD system memory accounting scheme. 15/16 of free system memory when kfd driver load. This deduct the system memory that OS already use.
