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.

2023-04-28drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()Hans de Goede
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on. And now testing on a Nextbook Ares 8A shows that panel_on_delay must always be honored otherwise the panel will not turn on. Instead of only always using regular msleep() for panel_on_delay do as Windows does and always use regular msleep() everywhere were intel_dsi_msleep() is used and drop the intel_dsi_msleep() helper. Changes in v2: - Replace all intel_dsi_msleep() calls instead of just the intel_dsi_msleep(panel_on_delay) call Cc: stable@vger.kernel.org Fixes: 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230425194441.68086-1-hdegoede@redhat.com

2023-02-17drm/i915: s/PIPECONF/TRANSCONF/Ville Syrjälä
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.

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.

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.

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>

Instead of sleeping panel_pwr_cycle_delay ms when turning the panel off, record the time it is turned off and if necessary wait any (remaining) time when the panel is turned on again. Also sleep the remaining time on shutdown, because on reboot the GOP will immediately turn on the panel again.

2021-04-12drm/i915/display/vlv_dsi: Do not skip panel_pwr_cycle_delay when disabling ↵Hans de Goede
the panel After the recently added commit fe0f1e3bfdfe ("drm/i915: Shut down displays gracefully on reboot"), the DSI panel on a Cherry Trail based Predia Basic tablet would no longer properly light up after reboot. I've managed to reproduce this without rebooting by doing: chvt 3; echo 1 > /sys/class/graphics/fb0/blank;\ echo 0 > /sys/class/graphics/fb0/blank Which rapidly turns the panel off and back on again. The vlv_dsi.c code uses an intel_dsi_msleep() helper for the various delays used for panel on/off, since starting with MIPI-sequences version >= 3 the delays are already included inside the MIPI-sequences. The problems exposed by the "Shut down displays gracefully on reboot" change, show that using this helper for the panel_pwr_cycle_delay is not the right thing to do. This has not been noticed until now because normally the panel never is cycled off and directly on again in quick succession. Change the msleep for the panel_pwr_cycle_delay to a normal msleep() call to avoid the panel staying black after a quick off + on cycle.

2021-04-07drm/i915/display: Eliminate IS_GEN9_{BC,LP}Matt Roper
Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the display code, we should also kill off our use of the IS_GEN9_* macros too. We'll do the conversion manually this time instead of using Coccinelle since the most logical substitution can depend heavily on the code context, and sometimes we can keep the code simpler if we make additional adjustments such as swapping the order of if/else arms. v2: - Restore a lost negation in intel_pll_is_valid().
