drm/amdgpu: workaround failed COW checks for Thunk VMAs

2021-07-16T07:22:57Z

KFD Thunk maps invisible VRAM BOs with PROT_NONE, MAP_PRIVATE. is_cow_mapping returns true for these mappings, which causes mmap to fail in ttm_bo_mmap_obj. As a workaround, clear VM_MAYWRITE for PROT_NONE-COW mappings. This should prevent the mapping from ever becoming writable and makes is_cow_mapping(vm_flags) false.

drm/amdgpu: remove amdgpu_vm_pt

2021-06-15T21:25:42Z

Page table entries are now in embedded in VM BO, so we do not need struct amdgpu_vm_pt. This patch replaces struct amdgpu_vm_pt with struct amdgpu_vm_bo_base. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

dma-buf: rename and cleanup dma_resv_get_excl v3

2021-06-06T09:17:58Z

When the comment needs to state explicitly that this doesn't get a reference to the object then the function is named rather badly. Rename the function and use rcu_dereference_check(), this way it can be used from both rcu as well as lock protected critical sections. v2: improve kerneldoc as suggested by Daniel v3: use dma_resv_excl_fence as function name Signed-off-by: Christian König Acked-by: Daniel Vetter Reviewed-by: Jason Ekstrand Link: https://patchwork.freedesktop.org/patch/msgid/20210602111714.212426-4-christian.koenig@amd.com

drm/amdgpu: Implement mmap as GEM object function

2021-05-26T18:56:23Z

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 Signed-off-by: Thomas Zimmermann Reviewed-by: Christian König Link: https://patchwork.freedesktop.org/patch/msgid/20210525151055.8174-3-tzimmermann@suse.de
