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: Enable HDR infoframe support

2019-05-22T19:46:35+00:00

Enable Dynamic Range and Mastering Infoframe for HDR content, which is defined in CEA 861.3 spec. The metadata will be computed based on blending policy in userspace compositors and passed as a connector property blob to driver. The same will be sent as infoframe to panel which support HDR. Added the const version of infoframe for DRM metadata for HDR. v2: Rebase and added Ville's POC changes. v3: No Change v4: Addressed Shashank's review comments and merged the patch making drm infoframe function arguments as constant. v5: Rebase v6: Fixed checkpatch warnings with --strict option. Addressed Shashank's review comments and added his RB. v7: Addressed Brian Starkey's review comments. Merged 2 patches into one. v8: Addressed Jonas Karlman review comments. v9: Addressed Jonas Karlman review comments. v10: Addressed Ville's review comments. v11: Added BUILD_BUG_ON and sizeof instead of magic numbers as per Ville's comments.

drm: Add colorspace info to AVI Infoframe

2019-02-19T17:51:12+00:00

This adds colorspace information to HDMI AVI infoframe. A helper function is added to program the same. v2: Moved this to drm core instead of i915 driver. v3: Exported the helper function. v4: Added separate HDMI specific macro as per CTA spec. 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. Moved the same out of header file to avoid any namespace issues. v7: Undef some macros to avoid any namespace collision as suggested by Ville. Added Ville's RB.
