We are currently having FIFO underruns happening for kms_dsc test case, problem is that, we check if curreny cdclk is >= pixel rate only if there is a single VDSC engine enabled(i.e dsc_split=false) however if we happen to have 2 VDSC engines enabled, we just kinda rely that this would be automatically enough. However pixel rate can be even >= than VDSC clock(cdclk) * 2, so in that case even with 2 VDSC engines enabled, we still need to tweak it up. So lets compare pixel rate with cdclk * VDSC engine count and check if it still requires bumping up. Previously we had to bump up CDCLK many times for similar reasons. v2: - Use new intel_dsc_get_num_vdsc_instances to determine number of VDSC engines, instead of slice count(Ankit Nautiyal) v3: - s/u8/int/ (Jani Nikula) v4: - Remove slice count mentions(Ankit Nautiyal) - Use DIV_ROUND_UP in order to make sure that resulting CDCLK would be always >= than required, after division(Ankit Nautiyal) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230704131758.14024-3-stanislav.lisovskiy@intel.com

Try to deal with duplicate child devices for the same DDI port by attempting to initialize them in VBT defined order The first on to succeed for a specific DDI port will be the one we use. We'll also get rid of i915->display.vbt.ports[] here as any conflicts will now be handled at encoder registration time rather than during VBT parsing. Note that intel_bios_encoder_data_lookup() still remaims for pre-DDI DP/HDMI ports as those don't (at least yet) use VBT driven initialization.

Stop with the VBT AUX CH sanitation, and instead just check that the appropriate AUX CH is still available when initializing a DP/TC port. The reason being that we want to start initializing ports in VBT order to deal with VBTs that declare child devices with seemingly conflicting ports. As the encoder initialization can fail for other reasons (at least for eDP+AUX) we can't know upfront which way the conflicts should be resolved. Note that the old way of sanitizing gave priority to the last port declared in the VBT, but now we sort of do the opposite by favoring the first encoder to successfully initialize. The reason for the old "last port wins" preference was eg. Asrock B250M-HDV where port A (eDP) and port E (DP->VGA) have an AUX CH conflict and we need to prefer port E. However with the new way port A (eDP) will be probed first, but will fail to probe due to HPD and thus port E will still win in the end. v2: Pimp the commit message (Jani) 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/20230630155846.29931-5-ville.syrjala@linux.intel.com

Stop with the VBT DDC pin sanitation, and instead just check that the appropriate DDC pin is still available when initializing a HDMI connector. The reason being that we want to start initializing ports in VBT order to deal with VBTs that declare child devices with seemingly conflicting ports. As the encoder initialization can fail for other reasons (at least for eDP+AUX) we can't know upfront which way the conflicts should be resolved. Note that the old way of sanitizing gave priority to the last port declared in the VBT, but now we sort of do the opposite by favoring the first encoder to successfully initialize. So far we're not aware of HDMI/DDC use cases where this would matter but for AUX CH (will be subject to a similar change) there are known cases where it matters. Also note that the old code fell back to the platform default DDC pin if the VBT pin was populated but invalid. That doesn't seem like such a great idea because the VBT might have later declared another port using that platform default pin, and so we might just be creating more DDC pin conflicts here. So lets not second guess the VBT and simply reject the entire HDMI encoder if the VBT DDC pin is invalid. v2: Pimp the commit message (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230630155846.29931-4-ville.syrjala@linux.intel.comReviewed-by: Jani Nikula <jani.nikula@intel.com>

Currently we just clamp that value to the highest supported one, however that means, we are not able to fit this into our available bandwidth range, so we might see glitches or FIFO underruns. While choosing less compressed bpp than min bpp required to handle the mode is harmless and might even save some bandwidth, choosing higher compressed bpp than min bpp required to handle the required mode config, can cause issues. So in that case lets just conclude that even with DSC, we are not able to comply with bandwidth requirements and fail. v2: - s/clamp_t/min_t/ (Luca Coelho) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Reviewed-by: Luca Coelho <luciano.coelho@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230629122534.8815-1-stanislav.lisovskiy@intel.com

DC states are disabled / re-enabled around each modeset, which may lead to a needless off->on->off toggling of the DC_off power well. This has some overhead as toggling DC states involves running a DMC firmware handler and also running a periodic firmware handler while DC states are enabled. The limit of when DC states have a benefit is at 30 FPS (using DC3co) and below 30 FPS (using DC5/6), where the firmware can actually disable clocks / power off power wells. Accordingly delay powering off the DC_off powerwell (which re-enables DC states) by 17 ms at the end of a modeset to avoid the above overhead at or above 60 FPS.

Instead of listing every platform's possible DDI outputs in intel_setup_outputs() just loop over the new port_mask to achieve the same thing. HSW/BDW were left as is since they still look at the straps as well. DSI is still a mess. For now just check for the relevant platforms explicitly.

The SDVO code already warns when the port in question doesn't actually support SDVO. Let's make that also bail the encoder registration like the generic assert_port_valid() we added. And add a similar thing for g4x HDMI, mainly because on g4x itsefl port D only supports DP but not SDVO/HDMI. For the other platforms the generic port_mask check should actually be sufficient, but since we're here might as well list the ports.

Sprinkle some asserts to catch any mishaps in the port_mask vs. output init. For DDI/DP/HDMI/SDVO I decided that we want to bail out for an invalid port since those are the encoder types where we might want consider driving the whole thing from the VBT child device list, and bogus VBTs could be a real issue (if for no other reason than the i915.vbt_firmware). For DVO and HSW/BDW CRT port I just threw the assert in there for good measure.

Sprinkle in some BUILD_BUG_ON()s to make sure some of the bitmasks used in the device info have enough bits. Do we have a better place for this sort of stuff? v2: Relocate to the new place 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/20230616140820.11726-4-ville.syrjala@linux.intel.com

Declare the available DVO/SDVO/HDMI/DP/DDI ports in the device info. The other outputs (LVDS/TV/DSI/VGA) are left out since for most of them we don't consider them as "ports". DSI we should probably perhaps include somehow in the device info. Just not sure how. Or we just introduce a HAS_DSI() and call it a day? TODO: figure out what to do about the subplatform stuff. Would it be better to declare those directly with a different device info or not? Also not sure the icl port-f stuff matters even. Bspec claims there are icl SKUs with far less ports than that and we don't seem to check for those either? v2: Fix TC5 vs. TC6 mixup on TGL (Jani) Drop DDI C for now on TGL, and add a FIXME (Jani) Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230616140820.11726-3-ville.syrjala@linux.intel.com
