Felix Kuehling fa5239f2af drm/amdgpu: workaround failed COW checks for Thunk VMAs ... 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. Fixes: f91142c621 ("drm/ttm: nuke VM_MIXEDMAP on BO mappings v3") Suggested-by: Daniel Vetter <daniel.vetter@intel.com> Tested-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210715190537.585456-1-Felix.Kuehling@amd.com Signed-off-by: Christian König <christian.koenig@amd.com>		2021-07-16 09:22:57 +02:00
