Subject: [PATCH v2 0/5] Add aspect ratio parsing
Date: Thu, 17 Dec 2015 19:12:55 +0530 [thread overview]
Message-ID: <1450359780-9022-1-git-send-email-shashank.sharma@intel.com> (raw)
Currently DRM framework doesn't parse aspect ratio of a videomode
while converting it from a umode->kmode or viceversa. This causes
modeset of CEA modes with incorrect aspect ratio.
While running HDMI complaince, tests (like 7-27) expect the DUT
to apply the mode as per the VIC, but as driver does not consider
the aspect ratio part while searching a mode from modedb, we end
up setting mode with a wrong VIC, causing the test to fail.
What this patch set does:
Patch 1-2
- Adds aspect ratio flags in the DRM layer, in form of flags.
- Adds parsing of aspect ratio, during conversion of a umode->kmode
and viceversa.
- Adds aspect ratio check while finding a mode, during modeset.
Patch 3-5
- Adds some new aspect ratio defined in CEA-861-F specs to
support HDMI 2.0 displays, in DRM and I915 layer.
V2: needed a rebase
Shashank Sharma (5):
drm: add picture aspect ratio flags
drm: Add aspect ratio parsing in DRM layer
video: Add new aspect ratios for HDMI 2.0
drm: Add flags for new aspect ratios
drm/i915: Add support for new aspect ratios
