2020-09-15drm/i915/pll: Centralize PLL_ENABLE register lookupAnusha Srivatsa1-17/+18
We currenty check for platform at multiple parts in the driver to grab the correct PLL.

2020-09-15drm/amdgpu/dc: Require primary plane to be enabled whenever the CRTC isMichel Dänzer1-22/+10
Don't check drm_crtc_state::active for this either, per its documentation in include/drm/drm_crtc.h: * Hence drivers must not consult @active in their various * &drm_mode_config_funcs.atomic_check callback to reject an atomic * commit. atomic_remove_fb disables the CRTC as needed for disabling the primary plane. This prevents at least the following problems if the primary plane gets disabled (e.g. due to destroying the FB assigned to the primary plane, as happens e.g. with mutter in Wayland mode): * The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID (which enables the cursor plane). * If the cursor plane was enabled, changing the legacy DPMS property value from off to on returned EINVAL. v2: * Minor changes to code comment and commit log, per review feedback.

why: some functions may need be dependent on stutter period in the future how: Extract from stutter calculations and place into perf_params structure Signed-off-by: Martin Leung <[email protected]> Acked-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2020-09-15drm/amd/display: Add trigger connector unplugEryk Brol1-2/+29
[why] We need a virtual tool that would emulate a physical connector unplug to usermode, while connector is still physically plugged in. [how] Added a new option to debugfs entry "trigger_hotplug". It emulates hotplug irq handling scenario by clearing DC and DM connector states. It can be triggered with the following command: echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug Signed-off-by: Eryk Brol <[email protected]> Signed-off-by: Mikita Lipski <[email protected]> Acked-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2020-09-15drm/amd/display: Add DSC force disable to dsc_clock_en debugfs entryEryk Brol4-13/+29
[why] For debug purposes we want not to enable DSC on certain connectors even if algorithm deesires to do so, instead it should enable DSC on other capable connectors or fail the atomic check. [how] Adding the third option to connector's debugfs entry dsc_clock_en. Accepted inputs: 0x0 - connector is using default DSC enablement policy 0x1 - force enable DSC on the connector, if it supports DSC 0x2 - force disable DSC on the connector, if DSC is supported Ex. # echo 0x2 > /sys/kernel/debug/dri/0/DP-1/dsc_clock_en Signed-off-by: Eryk Brol <[email protected]> Signed-off-by: Mikita Lipski <[email protected]> Acked-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
