[Intel-gfx] [PATCH i-g-t] [RFC] tests/kms_color: Fix pipe degamma subtests

[Vidya Srinivas]

We need to collect CRC with no degamma transformation
and after drawing gradient with degamma LUT.
This patch makes subtest pipe degamma code
similar to pipe gamma is written.

[Intel-gfx] [PATCH i-g-t] tests/kms_color: Remove gamma code from degamma tests

[Vidya Srinivas]

CRC should be collected without degamma transformation
and after drawing gradient with degamma LUT.
This patch removes things which are not related to degamma
and makes it similar to pipe gamma test.

[Intel-gfx] [PATCH] tests/kms_color: Disable gamma in degamma tests

[Vidya Srinivas]

This patch disables gamma in degamma subtest which is missing.
It compares CRC between (linear degamma + solid colors) and (max
degamma + gradient colors).

v2 - Addressed review comments from Bhanuprakash Modem

Please fix the comment s/"no degamma"/"linear degamma"/.
Also, we need to port this patch on "kms_color_chamelium".

These changes are not relevant to the degamma, but still we need these changes.
It would be good if we mention this in commit message.

[Srinivas, Vidya]

Thank you very much Bhanu for the review comments. I have addressed the review comments and resubmitted the patch.
Have also ported the changed to chamelium. Kindly have a check.

Regards
Vidya

[Intel-gfx] [PATCH i-g-t] tests/kms_color: Disable gamma in degamma tests

[Vidya Srinivas]

This patch disables gamma in degamma subtest which is missing.
It compares CRC between (linear degamma + solid colors) and (max
degamma + gradient colors). Patch also cleans up degamma before
exiting degamma test and cleans up gamma before exiting gamma
test.

v2 - Addressed review comments from Bhanuprakash Modem
Changed full degamma for reference CRC to linear degamma
Added clean up of degamma end of degamma test.

v3 - Addressed review comments from Bhanuprakash Modem
Ported changes to kms_color_chamelium

This can be disable_gamma(), right?

Also, please create separate patches for kms_color & kms_color_chamelium
under the same series.

[Intel-gfx] [PATCH i-g-t 1/2] tests/kms_color: Disable gamma in degamma tests

[Vidya Srinivas]

This patch disables gamma in degamma subtest which is missing.
It compares CRC between (linear degamma + solid colors) and (max
degamma + gradient colors). Patch also cleans up degamma before
exiting degamma test and cleans up gamma before exiting gamma
test.

v2 - Addressed review comments from Bhanuprakash Modem
Changed full degamma for reference CRC to linear degamma
Added clean up of degamma end of degamma test.

v3 - Addressed review comments from Bhanuprakash Modem
Fixed comments

[Intel-gfx] [PATCH i-g-t 0/2] Disable gamma in degamma subtests

[Vidya Srinivas]

This patch series disables gamma in degamma subtest which is missing.
It compares CRC between (linear degamma + solid colors) and (max
degamma + gradient colors). Patch also cleans up degamma before
exiting degamma test and cleans up gamma before exiting gamma
test. Changes are done for both kms_color and kms_color_chamelium.

v2 - Addressed review comments from Bhanuprakash Modem
Changed full degamma for reference CRC to linear degamma
Added clean up of degamma end of degamma test.

v3 - Addressed review comments from Bhanuprakash Modem
Fixed comments
