2022-06-20drm/i915/display: Re-add check for low voltage sku for max dp source rateJason A. Donenfeld
This reverts commit 73867c8709b5 ("drm/i915/display: Remove check for low voltage sku for max dp source rate"), which, on an i7-11850H iGPU with a Thinkpad X1 Extreme Gen 4, attached to a LG LP160UQ1-SPB1 embedded panel, causes wild flickering glitching technicolor pyrotechnics on resumption from suspend. The display shows strobing colors in an utter disaster explosion of pantone, as though bombs were dropped on the leprechauns at the base of the rainbow. Rebooting the machine fixes the issue, presumably because the display is initialized by firmware rather than by i915. Otherwise, the GPU appears to work fine. Bisection traced it back to this commit, which makes sense given the issues. Note: This re-opens, and puts back to the drawing board, https://gitlab.freedesktop.org/drm/intel/-/issues/5272 which was fixed by the regressing commit.

2022-06-16drm/i915/bios: Don't parse the DPS panel type when the VBT does not have itVille Syrjälä
Older VBTs don't have all the stuff we've defined for the LVDS options block (40). In particular we're currently parsing the DPS panel type bits even though they may not exist, which could mean we end up flagging the machine as supporting static DRRS when the VBT declared no such thing. We don't actually have a clear idea which VBT versions have which bits so we rely on the block size instead. Here's a quick list from my VBT stash: mgm version 108 -> 4 bytes alv version 120 -> 4 bytes cst version 134 -> 14 bytes pnv version 144 -> 14 bytes cl version 142 -> 16 bytes ctg version 155 -> 24 bytes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220615151445.8531-2-ville.syrjala@linux.intel.com Acked-by: Jani Nikula <jani.nikula@intel.com>

2022-06-01drm/i915: Treat DMRRS as static DRRSVille Syrjälä
Some machines declare DRRS type = seamless, DRRS = no, DMRRS = yes. I *think* DMRRS stands for "dynamcic media refresh rate", and I suspect the way it's meant to work is that it lets the driver switch refresh rates to match the frame rate for media playback. Obviously for us all that kind of policy stuff is entirely up to userspace, so the only thing we may do is make the extra refresh rate(s) available. So let's treat this case as just static DRRS for now. In the future We might want to differentiate the "seamless w/ downclocking" vs. "seamless w/o downclocking" cases so that we could do seamless refresh rate changes for systems that only claim to support DMRRS.

Fix various typos around "aggressiveness". Note that the VBT spec also sometimes missspells it as "agressiveness" so I guess that's where some of the typos came from.

2022-06-01drm/i915: Accept more fixed modes with VRR panelsVille Syrjälä
It seem that when dealing with VRR capable eDP panels we need to accept fixed modes with variable vblank length (which is what VRR varies dynamically). Typically the preferred mode seems to be a non-VRR more (lowish dotclock/refresh rate + short vblank). We also have examples where it looks like even the hblank length is a bit different between the preferred mode vs. VRR mode(s). So let's just accept anything that has matching hdisp+vdisp+flags. v2: Document that is_alt_drrs_mode() is a subset of is_alt_vrr_mode() (Jani) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/125 Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220531191844.11313-4-ville.syrjala@linux.intel.com

2022-05-31drm/i915: Check hw.enable and hw.active in intel_pipe_config_compare()Ville Syrjälä
Don't see a real reson not to check hw.active and hw.enable in intel_pipe_config_compare(). We do have some checks for them at a higher level, but I think better check them also in intel_pipe_config_compare() in case something else doesn't do a thorough enough job. Also shuffle the mst_master_transcoder check next to the cpu_transcoder check for a bit of consistency.
