If this loop iterated over the modifiers directly we wouldn't need that. The rest of the code only cares about the modifiers.I chose to loop over tiling constants as they are in a simple arithmetic order. anyhow I will just change that.Just put the two local_format stuff in an array and iterate over it.Also as mentioned above can I just add a check to skip Y-tiling tests for older platforms? igt_skip_on(intel_gen(intel_get_drm_devid(drm_fd)) < 9 && tiling == I915_TILING_Y);You can't do this here because the same subtest tests X tiling.
Okay! what if I just skip the loop for Y tiling with some message?
Will it be possible in just one subtest. I thought we will have to duplicate all the subtests for Y-tile case? Plz suggestPerhaps we could make Y tiling be a separate subtest? I'm not a huge fan of single tests that do tons of stuff.
Thanks, Praveen
