Author: Louis-Francis Ratté-Boulianne <[email protected]> Date: Thu Sep 21 11:19:23 2023 -0400 panfrost: Add env variable for max AFBC packing ratio Add `PAN_MAX_AFBC_PACKING_RATIO` variable. If the ratio (size of the packed resource) / (size of the sparse resource) * 100 is above that value, we don't care about packing it.
