[PATCH v4 0/4] Picture aspect ratio support in DRM layer

[PATCH v4 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 comments from Jim Bride, got r-b for all patches
V4: Added r-b from Jose for the series, and ack-by from Tomi on patch 3

[PATCH v4 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 v4 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).

Hmm. So now we have the mode aspect ratio infromation duplicated
in two different places. Not sure that won't lead to some confusion.
Although we do want the user to be able to override via the property I
suppose, so we'd have to change that (+ the inforframe code) to
look at the mode flags instead if we would eliminate
'picture_aspect_ratio'.

And that brings me to the other point. At least i915 will simply
override the mode's aspect ration with the property. So this looks like
a big no-op for now on i915. It's looking like we might need a new
propetty value to differentiate between "auto" and "none" for real.

In drm layer, this is the only place. Actually till now, DRM layer dint 
have the support for aspect ratio at all. This was causing
HDMI compliance tests like 7-27 fail, which expect a particular unique 
VIC in AVI infoframe on modeset.

I have given some details about this in cover-letter.

I had a small discussion on this with Daniel, and we discussed that it 
doesnt make sense to override just the aspect ratio if the monitor 
doesn't even support that aspect ratio.
And currently the was how this property is implemented is, we just 
override the aspect ratio without any validity check.

Now as we have all the supported aspect ratio added properly in the mode 
info itself, we need not to have this property at all, So Daniel 
suggested me to remove that property too.

Yes, This is a bug in I915. When I published the first version of this 
series, I had one patch, which was overriding the value only when the 
property is set.
This should be the right case. And then Daniel suggested to remove the 
property all together (and it makes sense as we have proper aspect 
ratios in mode information
itself) So I kept that patch separate, to be merged separately.

Now we have the exact aspect ratio given by monitor EDID, so IMHO it 
would be better if we can just have real aspect.

Yeah, removing the property entirely seems like an OKish solution since
userspace can just stuff that information into the mode flags instead.
The only slight concern is that someone's setup might depend on the
property, and now we're removing it.

Well, "real" isn't quite the right term. It's still a user specified
thing, which means the user can ask for somehting the display didn't
even advertise. Which is fine as such, however since the AVI infoframe
lacks the capability to transmit these new aspect ratios we have a bit
of problem on our hands if the user asks for something we can't even
tell the display to do. I guess we would just need to return an error
to the user in that case.

Thanks, will send the patch for it soon, adding you in the mail chain.

The current implementation which we have in andoroid, is hardware 
composer shows the whole mode in the list like:
- 1920x1080@60 16:9    /* From CEA block of EDID */
- 1920x1080@60 0:0        /* From detailed descriptor block of EDID */
- 1280x720@60 4:3          /* From CEA block of EDID */
-etc
These mode is the connector->probed_modes which we populated while 
parsing the EDID.
Now, when user selects the mode, its a complete set of resolution + 
refresh rate + aspect ratio, so user can only pick what
we are showing to it. In this case, there is no option which we cant 
support.

Do you think that there would be some other model of use case, where we 
can mix something among these?

Shashank


When user picks mode, its picks

You can't assume the user just picks the mode off the list. They can
stuff whatever random garbage into the mode if they wish.

Hmm. How's this gonna work? The AVI infoframe doesn't have these.

[PATCH v4 4/4] drm: Add and handle new aspect ratios in DRM layer

[Shashank Sharma]

HDMI 2.0/CEA-861-F introduces two new aspect ratios:
- 64:27
- 256:135

This patch:
-  Adds new DRM flags for to represent these new aspect ratios.
-  Adds new cases to handle these aspect ratios while converting
from user->kernel mode or vise versa.

Applied to drm-misc, thanks. I guess you'll follow up with i915 patches to
remove the picture aspect ratio for overrides eventually?

Thanks, Daniel

Thanks Daniel, and yes, its in my to-do list to remove the pic aspect 
ratio property, to override, as suggested by you in our last communication.
I was waiting for this series to be merged, so that I can give reference 
of this.

Will add you for the review of the patch,
