amdgpu_dm: no need to check return value of debugfs_create functions

2019-06-13T18:59:49Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

drm/amd/display: Add connector debugfs for "output_bpc"

2019-06-11T17:40:14Z

[Why] This will be useful for verifying whether we enter the correct output color depth from IGT. [How] Locks the connector and associated CRTC if available and outputs the current and maximum output bpc values. Example: cat /sys/kernel/debug/dri/0/DP-1/output_bpc Current: 8 Maximum: 10 v2: Drop unneeded connector status check Signed-off-by: Nicholas Kazlauskas Reviewed-by: David Francis Signed-off-by: Alex Deucher

drm/amd/display: Add debugfs entry for amdgpu_dm_visual_confirm

2019-04-10T18:53:27Z

[Why] DC provides a few visual confirmation debug options that can be dynamically changed at runtime to help debug surface programming issues but we don't have any way to access it from userspace. [How] Add the amdgpu_dm_visual_confirm debugfs entry. It accepts a string containing the DC visual confirm enum value using the debugfs attribute helpers. The debugfs_create_file_unsafe can be used instead of debugfs_create_file as per the documentation. v2: Use debugfs helpers for getting and setting the value (Christian) Cc: Leo Li Cc: Harry Wentland Signed-off-by: Nicholas Kazlauskas Reviewed-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: Add debugfs dpcd interface

2019-03-21T04:39:49Z

[Why] We need arbitrary read/write over DP AUX DPCD for debugging [How] Three debugfs entries Set the target address by writing to "aux_dpcd_address" (The first four bytes written are used) Set the transaction size in bytes by writing to "aux_dpcd_size" (The first four bytes written are used) Start a transaction by reading/writing "aux_dpcd_data" Do note: there is no concerrency protection at all Accessing these entries in quick succession can lead to strange behaviour Signed-off-by: David Francis Reviewed-by: Harry Wentland Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: Expose connector VRR range via debugfs

[Why] It's useful to know the min and max vrr range for IGT testing. [How] Expose the min and max vfreq for the connector via a debugfs file on the connector, "vrr_range".
