From: Felix Kuehling Date: Thu, 15 Mar 2018 21:27:40 +0000 (-0400) Subject: drm/amdgpu: Move KFD-specific fields into struct amdgpu_vm X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5b21d3e5fd2110df5a57a508188308351e698a5a;p=openwrt%2Fstaging%2Fblogic.git drm/amdgpu: Move KFD-specific fields into struct amdgpu_vm Remove struct amdkfd_vm and move the fields into struct amdgpu_vm. This will allow turning a VM created by a DRM render node into a KFD VM. v2: Removed vm_context field Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Oded Gabbay --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h index ad7292fc454c..6ba3dd689875 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h @@ -93,27 +93,6 @@ struct amdkfd_process_info { struct amdgpu_amdkfd_fence *eviction_fence; }; -/* struct amdkfd_vm - - * For Memory Eviction KGD requires a mechanism to keep track of all KFD BOs - * belonging to a KFD process.
