2025-04-22drm/i915/display: drop lots of unnecessary #include i915_drv.hJani Nikula
With the PCH macros switched to use struct intel_display, we have a number of files that no longer need struct drm_i915_private or anything else from i915_drv.h anymore. Remove the #include, and add the missing includes that were previously implicit. v2: Drop even more of the includes Reviewed-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Link: https://lore.kernel.org/r/5dc9e6a98461c344febac4c645875d8688eba906.1744880985.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2025-04-22drm/i915/display: pass struct intel_display to PCH macrosJani Nikula
Now that INTEL_PCH_TYPE() and HAS_PCH_*() macros are under display, and accept a struct intel_display pointer, use that instead of struct drm_i915_private pointer in display code. This is done naively by running: $ sed -i 's/\(INTEL_PCH_TYPE\|HAS_PCH_[A-Z0-9_-]*\)([^)]*)/\1(display)/g' \ $(find drivers/gpu/drm/i915/display -name "*.c") and fixing the fallout, i.e. removing unused local i915 variables and adding display variables where needed. v2: Rebase Reviewed-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Link: https://lore.kernel.org/r/999f4d7b8ed11739b1c5ec8d6408fc39d5e3776b.1744880985.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>

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.

2023-09-28drm/i915/fdi: Improve FDI BW sharing between pipe B and CImre Deak
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().

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.

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.

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.

2023-01-26drm/i915/edid: convert DP, HDMI and LVDS to drm_edidJani Nikula
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. (The big behavioural change conflating EDID reading with parsing and property update was done in commit 5186421cbfe2 ("drm: Introduce epoch counter to drm_connector")) v6: Rebase on drm_edid_connector_add_modes() v5: Fix potential uninitialized var use (kernel test robot <lkp@intel.com>) v4: Call drm_edid_connector_update() after reading HDMI/DP EDID v3: Don't leak vga switcheroo EDID in LVDS init (Ville) v2: Don't leak opregion fallback EDID (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/eabb4de932841b38b34cc2818ea9fbf7c10224fd.1674643465.git.jani.nikula@intel.com
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.
