From: Ankit Nautiyal <ankit.k.nautiyal@xxxxxxxxx> This patch series is a re-attempt to enable aspect ratio support in DRM layer. Currently the aspect ratio information gets lost in translation during a user->kernel mode or vice versa. The old patch series (https://pw-emeril.freedesktop.org/series/10850/) had 4 patches, out of which 2 patches were reverted due to lack of drm client protection while loading the aspect information. This patch series also includes 5 patches from Ville Syrjälä's series for 'Info-frame cleanup and fixes': https://patchwork.freedesktop.org/series/33730/ which fixes the mode matching mechanism via flags, and also ensures that no bogus aspect-ratios are sent in the AVI infoframes. This patch series, adds a DRM client option for aspect ratio, and loads aspect ratio flags, only when the client sets this cap. To test this patch, the testdiplay IGT test is modified to have an option to do a modeset with only aspect ratio modes. Also, there is a userspace implementation in Wayland/weston layer: https://patchwork.freedesktop.org/patch/188125/ (Which is already ACK'ed by wayland community.) This, helps us in passing HDMI compliance test cases like 7-27, where the test equipment applies a CEA mode, and expects the exact VIC in the AVI infoframes.
