drm/amdgpu: revert "add new bo flag that indicates BOs don't need fallback (v2)"

2018-05-15T18:43:19+00:00

This reverts commit 6f51d28bfe8e1a676de5cd877639245bed3cc818. Makes fallback handling to complicated. This is just a feature for the GEM interface and shouldn't leak into the core BO create function. Signed-off-by: Christian König Acked-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amdgpu: add new bo flag that indicates BOs don't need fallback (v2)

2018-04-11T18:08:01+00:00

user cases: 1. KFD wraps amdgpu_bo_create, they have no fallback case which is different with amdgpu_gem_object_create. since upstream branch has no amdgpu_amdkfd_gpuvm.c, which need KFD guys add this flag to __alloc_memory_of_gpu: + flags |= AMDGPU_GEM_CREATE_NO_FALLBACK; 2. UMD can specify this flag for their allocation as well if they like. v2: squash in merge conflict fix (Chunming) Signed-off-by: Chunming Zhou Acked-by: Felix Kuehling Cc: felix.kuehling@amd.com Signed-off-by: Alex Deucher
