[PATCH v3 0/8] Aspect ratio support in DRM layer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 3 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.

This patch series, adds a DRM client option for aspect ratio, and loads aspect
ratio flags, only when the client sets this cap. 
Also, to test this patch series there is a userspace implementation by
Ankit Nautiyal 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.

Ankit Nautiyal (3):
  drm: Add DRM client cap for aspect-ratio
  drm: Handle aspect ratio info in atomic and legacy modeset paths
  drm: Expose modes with aspect ratio, only if requested

Sharma, Shashank (2):
  drm: Add aspect ratio parsing in DRM layer
  drm: Add and handle new aspect ratios in DRM layer

Ville Syrjälä (3):
  drm/modes: Introduce drm_mode_match()
  drm/edid: Use drm_mode_match_no_clocks_no_stereo() for consistentcy
  drm/edid: Fix cea mode aspect ratio handling
