2023-05-05drm/i915/display: Add new member to configure PCON color conversionAnkit Nautiyal
The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch adds new member to crtc_state to represent the final output_format to the sink. In case of a DFP this can be different than the output_format, as per the format conversion done via the PCON. This will help to store only the format conversion capabilities of the DP device in intel_dp->dfp, and use crtc_state to compute and store the configuration for color/format conversion for a given mode. v2: modified the new member to crtc_state to represent the final output_format that eaches the sink, after possible conversion by PCON kind of devices. (Ville) v3: Addressed comments from Ville: -Added comments to clarify difference between sink_format and output_format. -Corrected the order of setting sink_format and output_format. -Added readout for sink_format in get_pipe_config hooks. v4: Set sink_format for intel_sdvo too. (Ville) v5: Rebased. v6: Fixed condition to go for YCbCr420 format for dp and hdmi. (Ville) v7: Fix the condition to set sink_format for HDMI. Set hdmi output_format simply as sink_format.

2023-01-26drm/i915/panel: move panel fixed EDID to struct intel_panelJani Nikula
It's a bit confusing to have two cached EDIDs in struct intel_connector with slightly different purposes. Make the distinction a bit clearer by moving the EDID cached for eDP and LVDS panels at connector init time to struct intel_panel, and name it fixed_edid. That's what it is, a fixed EDID for the panels.

2022-12-09drm/i915: Do panel VBT init early if the VBT declares an explicit panel typeVille Syrjälä
Lots of ADL machines out there with bogus VBTs that declare two eDP child devices. In order for those to work we need to figure out which power sequencer to use before we try the EDID read. So let's do the panel VBT init early if we can, falling back to the post-EDID init otherwise. The post-EDID init panel_type=0xff approach of assuming the power sequencer should already be enabled doesn't really work with multiple eDP panels, and currently we just end up using the same power sequencer for both eDP ports, which at least confuses the wakeref tracking, and potentially also causes us to toggle the VDD for the panel when we should not.

2022-11-11drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula
Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place. Also some places actually needed i915_irq.h too.

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).

But the check was just a micro optimization so removing it doesn't actually mattter for correctness. TODO: Lot's of cleanup to be done in the future.

The slight difference in behaviour is that the SDVO code currently bails if it can't find the preferred mode, whereas intel_panel_edid_fixed_mode() will fall back to just returning the first mode from the probed_modes list.

Abstract away the details on where we store the fixed/downclock modes, and also how we select them. Will be useful for static DRRS (aka. allowing the user to select the refresh rate for the panel). We pass in the user requested mode to intel_panel_fixed_mode() so that in the future it may try to match the refresh rate. And intel_panel_downclock_mode() gets passed the adjusted_mode we actually chose to use so that it may find a suitable lower resresh rate variant. v2: Hook it up for all encoders s/fixed_mode/adjusted_mode/ in intel_panel_downclock_mode() (Jani) Elaborate on the choice or arguments for the functions (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220311172428.14685-7-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

2021-09-30drm/i915: Introduce intel_panel_compute_config()Ville Syrjälä
Let's introduce a compute_config() helper for fixed mode panels. For now all it does is the fixed_mode->adjusted_mode copy. Note that with sDVO we have to ask the external encoder chip to spit out our actual display timings for us, so the fixed_mode to adjusted_mode copy done by intel_panel_compute_config() is redundant, but we still want to use it to do other checks for us later. We'll be fine so long as we only call it before intel_sdvo_get_preferred_input_mode() overwrites adjusted_mode with the timings from the encoder. v2: Use intel_panel_compute_config() with sDVO Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210927185207.13620-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
2021-09-30drm/i915: Use intel_panel_mode_valid() for DSI/LVDS/(s)DVOVille Syrjälä
All fixed mode panels should behave the same way when it comes to mode filtering. Reuse the intel_panel_mode_valid() for all of them. This changes the behaviour to match what we do for eDP, ie. reject anything that doesn't exactly match the fixed mode dimensions. Users can still manually provide different sized modes which will be handled by the panel fitter just as before. The difference is that we can no longer report funny modes in the connector's mode list.
