[igt-dev] [PATCH] tests/intel/kms_flip_scaled_crc: Add support for FP16 compressed formats

[Sharma, Swati2]

Hi Melanie,

It seems tests are skipping on MTLP
https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_10024/shards-all.html?testfilter=4tilemtlrcccs

Test requirement not met in function setup_fb, file 
../../../usr/src/igt-gpu-tools/tests/intel/kms_flip_scaled_crc.c:622:
Test requirement: igt_display_has_format_mod(&data->display, format, 
modifier)
Dynamic subtest pipe-A-default-mode: SKIP (0.378s)

Can you check once?
