[igt-dev] [PATCH i-g-t] [i-g-t] tests/kms_plane_scaling: Change minimum fb height for YUV 420 planar

[igt-dev] [PATCH i-g-t] [i-g-t] tests/kms_plane_scaling: Change minimum fb height for YUV 420 planar

[Vidya Srinivas]

When the plane scaling is used with YUV 420 planar formats,
the height should be a minimum of 16 scanlines as per BSpec.
Minimum of 8 scanlines is for non-YUV 420 planar formats.
Patch changes the minimum fb height being used in the test
in case of YUV 420 planar (currently done for NV12, as
that is the only planar format supported)

v2: Addressed review comments from Maarten

This doesn't really say anything meaningful. In the future, please state
the actual changes.

IMO it's easier to read when you have an if-else instead of overwriting
the previous values in some cases.

No way that CI can test this currently. so pushed. :)

Hey, no apologies necessary. Maarten already did the important part of
reviewing the functionality, this was just me opinioning on style.

Re: [igt-dev] [PATCH i-g-t] [i-g-t] tests/kms_plane_scaling: Change minimum fb height for YUV 420 planar

[Srinivas, Vidya]

Hi Maarten,

Apologies :(

From the CI results, I checked that when 17x17 buffer is requested, KMD makes it 16  and
again the check fails (which we added in skl_update_scaler in range check) and due to this we see igt exits
from pixel format test of kms_plane_scaling.

Also for underruns:
Until I give a multiplier of 4 (which will be > 16), it would take 16 only and hence the fifo underruns.

From BSpec: Display WA 1106:
Display corruption/color shift observed when using NV12 with 270 rotation or 90 rotation + horizontal flip.
WA: NV12 with 270 rotation or 90 rotation + horizontal flip requires the programmed plane height to be a multiple of 4.

We need to set width = height = 20 in i-g-t. I will send a FIXME patch. Can you please help merge?

Sorry, trybot did not catch it then as it considered the older i-g-t and showed scaler out of range for 9x9
And I assumed everything is right/expected.

Regards
Vidya

Allow igt_create_fb_with_bo_size to fail, but not kms_addfb, then handle its failure in kms_frontbuffer_tracking

and then do something like this:


for (height = 1; height < 1024; height *= 2) {

if (igt_create_fb_with_bo_size(height + 1, height + 1) > 0)

        break;

}

igt_assert(height < 1024);

width = ++height;

This should work regardless of format..

Hi Maarten. We can. But since min for non-YUV was 8, we thought
the purpose of the test was to create the minimal possible buffer.
So we dint change that. What do you suggest? Please let us know.

Hi Maarten. We should. We will be doing that also and refloat the series tomorrow.

Could we set height to 17 for all?

[igt-dev] [PATCH i-g-t] [i-g-t] tests/kms_plane_scaling: Change minimum fb height for YUV 420 planar

[Vidya Srinivas]

When the plane scaling is used with YUV 420 planar formats,
the height should be a minimum of 16 scanlines as per BSpec
Minimum of 8 scanlines is for non-YUV 420 planar formats.
Patch changes the minimum fb height being used in the test
in case of YUV 420 planar (for now NV12 as only that is supported).
