drm/amdgpu: revise RLCG access path

2020-03-16T20:17:55Z

what changed: 1)provide new implementation interface for the rlcg access path 2)put SQ_CMD/SQ_IND_INDEX to GFX9 RLCG path to let debugfs's reg_op function can access reg that need RLCG path help now even debugfs's reg_op can used to dump wave. tested-by: Monk Liu tested-by: Zhou pengju Signed-off-by: Zhou pengju Signed-off-by: Monk Liu Reviewed-by: Emily Deng Signed-off-by: Alex Deucher

drm/amd/amdgpu: Fix GPR read from debugfs (v2)

2020-03-13T15:52:34Z

The offset into the array was specified in bytes but should be in terms of 32-bit words. Also prevent large reads that would also cause a buffer overread. v2: Read from correct offset from internal storage buffer.

drm/amdgpu: no need to clean debugfs at amdgpu

2020-02-28T21:59:22Z

drm_minor_unregister will invoke drm_debugfs_cleanup to clean all the child node under primary minor node. We don't need to invoke amdgpu_debugfs_fini and amdgpu_debugfs_regs_cleanup to clean agian. Otherwise, it will raise the NULL pointer like below.
