This workaround is specific for a particular panel on Google chromebook project. When user space daemon enter idle state. It request adjust brightness to 0, turn backlight_enable signal off and keep eDP main link active. On general LCD, this behavior might not be a problem. But on this panel, its tcon would expect source to execute full eDP power off sequence after drop backlight_enable signal. Without eDP power off sequence. Even source try to turn backlight_enable signal on and restore proper brightness level. This panel is not able to light on again. This WA ignored the request from user space daemon to disable backlight_enable signal and keep it on always. When user space request kernel to turn eDP display off, kernel driver still can control backlight_enable signal properly. It would not impact standard eDP power off sequence. v2: 1. modify the quirk name and debug messages. 2. unregister backlight.power callback for specific device. v3: 1. modify debug output messages. 2. use DMI_EXACT_MATCH instead of DMI_MATCH.

Add a single point of truth for figuring out the primary/secondary crtc for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple places. Also fix the pipe validity checks to properly take non-contiguous pipes into account. The current checks may theoretically overflow i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

Disconnect TypeC PHYs during system suspend and shutdown, even with the corresponding TypeC sink still plugged to its connector, since leaving the PHY connected causes havoc at least during system resume in the presence of an Nvidia card. Note that this will only make a difference in the TypeC DP alternate mode, since in Thunderbolt alternate mode the PHY is never owned by the display engine and there is no notion of PHY ownership in legacy mode (the display engine being the only possible owner in that mode and the TypeC subsystem not having anything to do with the port in that case).

It's becoming pretty cumbersome to track the features enabled going back to GEN7. Gather the XE_LPD display features together in XE_LPD_FEATURES macro so they are sufficient to describe the display features. In ADL-P's device_info we set has_psr_hw_tracking to 0 as it would otherwise be enabled since it is inheriting from GEN12_FEATURES. Signed-off-by:

Currently as the workaround is applied the screen flickers. As a result we do not achieve seamless boot experience. Avoiding the issue in the common use-case might be hard, although we can resolve it for dual GPU setups - when the "other" GPU is primary and/or outputs are connected to it. With this I was able to get seamless experience on my Intel/Nvidia box, running systemd-boot and sddm/Xorg. Note that the i915 driver is within initrd while the Nvidia one is not. Without this patch, the splash presented by systemd-boot (UEFI BGRT) is torn down as the code-path kicks in, leaving the monitor blank until the login manager starts. Same issue were reported with plymouth/grub, although personally I wasn't able to get them to behave on my setup. Suggested-by:

We currently treat same slice mask as a same DBuf state and skip updating the Dbuf slices, if we detect that. This is wrong as if we have a multi to single pipe change or vice versa, that would be treated as a same Dbuf state and thus no changes required, so we don't get Mbus updated, causing issues. Solution: check also mbus_join, in addition to slices mask. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

This introduces the following function that can exit and activate a psr source when intel_psr is already enabled. - intel_psr_pause(): Pause current PSR.

Commit 78b772e1 ("drm/i915/display: Fill PSR state during hardware configuration read out") is not allowing fastsets to happen when PSR states changes but PSR is a feature that can be enabled and disabled during fastsets. So here moving the PSR pipe conf checks to a block that is only executed when checking if HW state matches with requested state, not during the phase where it checks if fastset is possible or not. There still a state mismatch not allowing fastsets between states turning off or on PSR because of crtc_state->infoframes.enable BIT(DP_SDP_VSC) but at least for now it will allow a fastset between PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not work with PSR2, but the remaning issue will be fixed in a future patch.
