drm/edid: parse CEA blocks embedded in DisplayID

2019-07-26T07:11:03+00:00

commit e28ad544f462231d3fd081a7316339359efbb481 upstream. DisplayID blocks allow embedding of CEA blocks. The payloads are identical to traditional top level CEA extension blocks, but the header is slightly different. This change allows the CEA parser to find a CEA block inside a DisplayID block. Additionally, it adds support for parsing the embedded CTA header. No further changes are necessary due to payload parity. This change fixes audio support for the Valve Index HMD.

drm: add fallback override/firmware EDID modes workaround

2019-06-12T10:26:25+00:00

We've moved the override and firmware EDID (simply "override EDID" from now on) handling to the low level drm_do_get_edid() function in order to transparently use the override throughout the stack. The idea is that you get the override EDID via the ->get_modes() hook. Unfortunately, there are scenarios where the DDC probe in drm_get_edid() called via ->get_modes() fails, although the preceding ->detect() succeeds. In the case reported by Paul Wise, the ->detect() hook, intel_crt_detect(), relies on hotplug detect, bypassing the DDC. In the case reported by Ilpo Järvinen, there is no ->detect() hook, which is interpreted as connected. The subsequent DDC probe reached via ->get_modes() fails, and we don't even look at the override EDID, resulting in no modes being added. Because drm_get_edid() is used via ->detect() all over the place, we can't trivially remove the DDC probe, as it leads to override EDID effectively meaning connector forcing. The goal is that connector forcing and override EDID remain orthogonal. Generally, the underlying problem here is the conflation of ->detect() and ->get_modes() via drm_get_edid(). The former should just detect, and the latter should just get the modes, typically via reading the EDID. As long as drm_get_edid() is used in ->detect(), it needs to retain the DDC probe. Or such users need to have a separate DDC probe step first. The EDID caching between ->detect() and ->get_modes() done by some drivers is a further complication that prevents us from making drm_do_get_edid() adapt to the two cases. Work around the regression by falling back to a separate attempt at getting the override EDID at drm_helper_probe_single_connector_modes() level. With a working DDC and override EDID, it'll never be called; the override EDID will come via ->get_modes(). There will still be a failing DDC probe attempt in the cases that require the fallback. v2: - Call drm_connector_update_edid_property (Paul) - Update commit message about EDID caching (Daniel) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107583 Reported-by: Paul Wise Cc: Paul Wise References: http://mid.mail-archive.com/alpine.DEB.2.20.1905262211270.24390@whs-18.cs.helsinki.fi Reported-by: Ilpo Järvinen Cc: Ilpo Järvinen Suggested-by: Daniel Vetter References: 15f080f08d48 ("drm/edid: respect connector force for drm_get_edid ddc probe") Fixes: 53fd40a90f3c ("drm: handle override and firmware EDID at drm_do_get_edid() level") Cc: # v4.15+ 56a2b7f2a39a drm/edid: abstract override/firmware EDID retrieval Cc: # v4.15+ Cc: Daniel Vetter Cc: Ville Syrjälä Cc: Harish Chegondi Tested-by: Paul Wise Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20190610093054.28445-1-jani.nikula@intel.com

drm/edid: Remove defunct EDID_QUIRK_FIRST_DETAILED_PREFERRED

2019-03-27T11:55:13+00:00

Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything. Its counterpart in f86EdidModes.c is properly hooked up but somehow that functionality was lost when it was copied into the kernel. The concensus seems to be that this quirk is a bit misguided anyway so let's nuke the leftovers.

This is separate from user exposed enum values. This is as per Ville's suggestion. v5: Appended BT709 and SMPTE 170M with YCC information as per Ville's review comment to be clear and not to be confused with RGB. v6: Added bit wise macro for various fields of colorimetry for easier understanding and review as per Ville's comments.
