[PATCH] drm/i915/glk: Improve rounding caused by pre-CSC gamma tables

[PATCH] drm/i915/glk: Improve rounding caused by pre-CSC gamma tables

[Ander Conselvan de Oliveira]

The 33rd entry in the pre-CSC gamma table in Geminilake can represent a
value of 1.0 as 17 bits fixed point with one integer bit. However, the
table was generated such that the value of 1.0 would be 0.ffff with
all the intervals scaled accordingly. For instance, 0.5 mapped to
0.7fff instead of 0.8000.

For a reason that is not clear to the author, the rounding seems to be
different when a cursor plane is used, leading to some seemingly random
failures of the kms_cursor_crc igt tests. The differences weren't
perceptible at 8bpc with images captured by a Chamelium device, but did
cause CRC mismatches.

[PATCH i-g-t] kms_cursor_crc: Add a subtest with a 256x256 gradient cursor

[Ander Conselvan de Oliveira]

Some of the kms_cursor_crc subtests where failing on Geminilake. The
root cause was an error on programming the pre-CSC gamma tables, which
led to small rounding errors that, although not sufficient to change the
image as captured at 8bpc with the Chamelium, were enough to generate a
different CRC. It is not clear why the rounding is different when the
cursor is enabled, but this was caught by chance, since the cursor would
only be exercised with limited color combinations.

To improve coverage, add a test that uses a gradient covering all
possible 8bit values for a channel.

Just realized this needs an igt_require(max_cursor_[wh] >= 256).

Actually all the gamma tables except the legacy 8bpc gamma have
this 1.0 thing. And yet we program them all to <1.0. But I guess
in most cases that doesn't cause any issues. But I think this is
definitely something someone should look at.

One problem is that the uapi we got in the end uses 0.16 representation
instead of the 8.24 that I thought we were going with. So the conversion
isn't going to as nice as it could be I suppose.

But yeah, this patch seems trouble free since we don't yet expose
the pre-csc gamma to userspace.
