[PATCH v3 0/4]: Picture aspect ratio support in DRM layer

[PATCH v3 0/4]: Picture aspect ratio support in DRM layer

[Shashank Sharma]

This patch series adds 4 patches.
- The first two patches add aspect ratio support in DRM layes
- Next two patches add new aspect ratios defined in CEA-861-F
  supported for HDMI 2.0 4k modes.

Adding aspect ratio support in DRM layer:
- The CEA videmodes contain aspect ratio information, which we
  parse when we read the modes from EDID. But while transforming
  user_mode to kernel_mode or viceversa, DRM layer lose this
  information.
- HDMI compliance testing for CEA modes, expects the AVI info frames
  to contain exact VIC no for the 'video mode under test'. Now CEA
  modes have different VIC for same modes but different aspect ratio
  for example:
        VIC 2 = 720x480@60 4:3
        VIC 3 = 720x480@60 16:9
  In this way, lack of aspect ratio information, can cause wrong VIC
  no in AVI IF, causing HDMI complaince test to fail.
- This patch set adds code, which embeds the aspect ratio information
  also in DRM video mode flags, and uses it while comparing two modes.

Adding new aspect ratios for HDMI 2.0
- CEA-861-F defines two new aspect ratios, to be used for 4k HDMI 2.0
  modes.
        - 64:27
        - 256:135
Last two patches in the series, adds code to handle these new
aspect ratios.

V3: Fixed review comments from Jim Bride, got r-b for all patches

I am using the previous version of these patches, the
functionality remains the same so you can add my reviewed-by for
the whole series if you want. Are you still planning in sending
the patches for the new VIC's introduced in CEA-861-F?

Thanks Joes. I will add a V4 with your r-b.

Yes, the very next step is the patch with new VICs.

[PATCH v3 1/4] drm: add picture aspect ratio flags

[Shashank Sharma]

This patch adds drm flag bits for aspect ratio information

Currently drm flag bits don't have field for mode's picture
aspect ratio. This field will help the driver to pick mode with
right aspect ratio, and help in setting right VIC field in avi
infoframes.

[PATCH v3 2/4] drm: Add aspect ratio parsing in DRM layer

[Shashank Sharma]

Current DRM layer functions don't parse aspect ratio information
while converting a user mode->kernel mode or vice versa. This
causes modeset to pick mode with wrong aspect ratio, eventually
causing failures in HDMI compliance test cases, due to wrong VIC.

This patch adds aspect ratio information in DRM's mode conversion
and mode comparision functions, to make sure kernel picks mode
with right aspect ratio (as per the VIC).

[PATCH v3 0/4] Picture aspect ratio support in DRM layer

[Shashank Sharma]

This patch series adds 4 patches.
- The first two patches add aspect ratio support in DRM layes
- Next two patches add new aspect ratios defined in CEA-861-F
  supported for HDMI 2.0 4k modes.

Adding aspect ratio support in DRM layer:
- The CEA videmodes contain aspect ratio information, which we
  parse when we read the modes from EDID. But while transforming
  user_mode to kernel_mode or viceversa, DRM layer lose this
  information.
- HDMI compliance testing for CEA modes, expects the AVI info frames
  to contain exact VIC no for the 'video mode under test'. Now CEA
  modes have different VIC for same modes but different aspect ratio
  for example:
        VIC 2 = 720x480@60 4:3
        VIC 3 = 720x480@60 16:9
  In this way, lack of aspect ratio information, can cause wrong VIC
  no in AVI IF, causing HDMI complaince test to fail.
- This patch set adds code, which embeds the aspect ratio information
  also in DRM video mode flags, and uses it while comparing two modes.

Adding new aspect ratios for HDMI 2.0
- CEA-861-F defines two new aspect ratios, to be used for 4k HDMI 2.0
  modes.
        - 64:27
        - 256:135
Last two patches in the series, adds code to handle these new
aspect ratios.

V2: Fixed review comments from Sean, Emil, Daniel

V3: Fixed review comment from Jim Bride, got r-b for all patches

[Sharma, Shashank]

Please ignore this series, I mixed up one patch from LSPCON in here. 
Will send the right series in few minutes.
