drm/i915: Skip some timing checks on BXT/GLK DSI transcoders Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

drm/i915/fdi: Improve FDI BW sharing between pipe B and C At the moment modesetting pipe C on IVB will fail if pipe B uses 4 FDI lanes. Make the BW sharing more dynamic by trying to reduce pipe B's link bpp in this case, until pipe B uses only up to 2 FDI lanes. For this instead of the encoder compute config retry loop - which reduced link bpp only for the encoder's pipe - reduce the maximum link bpp for pipe B/C as required after all CRTC states are computed and recompute the CRTC states with the new bpp limit. Atm, all FDI encoder's compute config function returns an error if a BW constrain prevents increasing the pipe bpp value. The corresponding crtc_state->bw_constrained check can be replaced with checking crtc_state->max_link_bpp_x16, add TODO comments for this. SDVO is an exception where this case is only handled in the outer config retry loop, failing the modeset with a WARN, add a FIXME comment to handle this in the encoder code similarly to other encoders. v2: - Don't assume that a CRTC is already in the atomic state, while reducing its link bpp. - Add DocBook description to intel_fdi_atomic_check_link(). v3: - Enable BW management for FDI links in a separate patch. (Ville) v4: (Ville) - Fail the SDVO encoder config computation if it doesn't support the link bpp limit. - Add TODO: comments about checking link_bpp_x16 instead of bw_constrained. v5: - Replace link bpp limit check with a FIXME: comment in intel_sdvo_compute_config().

drm/i915/display: Add new member to configure PCON color conversion 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.

drm/i915: s/PIPECONF/TRANSCONF/ Rename PIPECONF to TRANSCONF to make it clear what it actually applies to. While the usual convention is to pick the earliers name I think in this case it's more clear to use the later name. Especially as even the register offset is in the wrong range (0x70000 vs. 0x60000) and thus makes it look like this is per-pipe. There is one place in gvt that's doing something with TRANSCONF while iterating with for_each_pipe(). So that might not be doing the right thing for TRANSCODER_EDP, dunno. Not knowing what it does I left it as is to avoid breakage.

drm/i915/edid: convert DP, HDMI and LVDS to drm_edid Convert all the connectors that use cached connector edid and detect_edid to drm_edid. Since drm_get_edid() calls drm_connector_update_edid_property() while drm_edid_read*() do not, we need to call drm_edid_connector_update() separately, in part due to the EDID caching behaviour in HDMI and DP. Especially DP depends on the details parsed from EDID.

drm/i915: Do panel VBT init early if the VBT declares an explicit panel type 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.

drm/i915: stop including i915_irq.h from i915_trace.h 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.

drm/i915: Simplify intel_panel_add_edid_alt_fixed_modes() Since commit a5810f551d0a ("drm/i915: Allow more varied alternate fixed modes for panels") intel_panel_add_edid_alt_fixed_modes() no longer considers vrr vs. drrs separately.

drm/i915: Accept more fixed modes with VRR panels 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

drm/i915/bios: Split VBT data into per-panel vs. global parts Move the panel specific VBT parsing to happen during the output probing stage. Needs to be done because the VBT parsing will need to look at the EDID to determine the correct panel_type on some machines. We split the parsed VBT data (i915->vbt) along the same boundary. For the moment we just hoist all the panel specific stuff into connector->panel.vbt since that seems like the most convenient place for eg. the backlight code. Note that we simply drop the drrs type check from intel_drrs_frontbuffer_update() since that operates on the whole device rather than a specific connector/encoder. 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. Eg. most of the DSI stuff could probably be eliminated entirely and just parsed on demand during DSI init. v2: Note the intel_drrs_frontbuffer_update() change Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220510104242.6099-13-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

drm/i915/display: rename display version macros While converting the rest of the driver to use GRAPHICS_VER() and MEDIA_VER(), following what was done for display, some discussions went back on what we did for display: 1) Why is the == comparison special that deserves a separate macro instead of just getting the version and comparing directly like is done for >, >=, <=? 2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for brevity. If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators.

drm/i915/params: switch to device specific parameters Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20200618150402.14022-1-jani.nikula@intel.com

drm/i915: Pass atomic state to encoder hooks We're going to want access to the atomic state for iterating the slave crtcs when enabling the port sync master crtc. Pass the atomic state all the way down. The alternative would be yet another encoder hook which we'll have to call after all the normal modeset stuff is done. Not really a fan of yet another hook just for this. Note that during readout state sanitation we are now going to pass NULL as the atomic state since we don't have one. We need to change that and then we can also s/crtc_state/crtc/ and s/conn_state/conn/ for the encoder hooks as well.

drm/i915: Wrappers for display register waits To reduce the number of explicit dev_priv->uncore calls in the display code ahead of the introduction of dev_priv->de_uncore, this patch introduces a wrapper for one of the main usages of it, the register waits. When we transition to the new uncore, we can just update the wrapper to point to the appropriate structure. Since the vast majority of waits are on a set or clear of a bit or mask, add set & clear flavours of the wrapper to simplify the code.
