drm/amd/display: Add DC Debug mask to disable features for bringup

2020-05-21T16:37:19Z

[Why] At bringup we want to be able to disable various power features. [How] These features are already exposed as dc_debug_options and exercised on other OSes. Create a new dc_debug_mask module parameter and expose relevant bits, in particular * DC_DISABLE_PIPE_SPLIT * DC_DISABLE_STUTTER * DC_DISABLE_DSC * DC_DISABLE_CLOCK_GATING Signed-off-by: Harry Wentland Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amdgpu: Add DC feature mask to disable fractional pwm

2019-10-25T20:50:10Z

[Why] Some LED panel drivers might not like fractional PWM. In such cases, backlight flickering may be observed. [How] Add a DC feature mask to disable fractional PWM, and associate it with the preexisting dc_config flag. The flag is only plumbed through the dmcu firmware, so plumb it through the driver path as well. To disable, add the following to the linux cmdline: amdgpu.dcfeaturemask=0x4 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204957 Signed-off-by: Leo Li Reviewed-by: Anthony Koo Tested-by: Lukáš Krejčí Signed-off-by: Alex Deucher

drm/amdgpu/display: add dc feature mask for psr enablement

2019-10-25T20:50:10Z

[Why] Adding psr mask to dc features allows selectively disable/enable psr. Current psr implementation may not work with non-pageflipping application. Until resolved it should be disabled by default. [How] Add dcfeaturemask for psr enablement. Disable by default. To enable set amdgpu.dcfeaturemask=0x8 in grub kernel command line.
