drm: move amd_gpu_scheduler into common location 2017-12-07T16:51:56+00:00 Lucas Stach l.stach@pengutronix.de 2017-12-06T16:49:39+00:00 1b1f42d8fde4fef1ed7873bf5aa91755f8c3de35 This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.
