amdkfd: Add amdkfd skeleton driver This patch adds the amdkfd skeleton driver. The driver does nothing except define a /dev/kfd device. It returns -ENODEV on all amdkfd IOCTLs. v3: Move bool field to the end of structure, removed the pmc ioctls and added a meaningful error message for ioctl error. v5: Create a new folder drm/amd and move amdkfd from drm/radeon/ to drm/amd/ Remove scheduler_class from kfd_priv.h as it was never used Add skeleton implementation of the Get Version IOCTL v6: Update module version to the correct number and remove the "default m" from the Kconfig file Signed-off-by: Oded Gabbay <oded.gabbay@amd.com> 2014-07-17 02:08:55 +08:00			`#`

drm/amdgpu: Merge amdkfd into amdgpu Since KFD is only supported by single GPU driver, it makes sense to merge amdgpu and amdkfd into one module. This patch is the initial step: merge Kconfig and Makefile. v2: also remove kfd from drm Kconfig Signed-off-by: Amber Lin <Amber.Lin@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 2018-08-23 04:48:50 +08:00			`bool "HSA kernel driver for AMD GPU devices"`
