Author: Erik Faye-Lund <[email protected]> Date: Wed Nov 1 15:11:32 2023 +0100 panfrost: bypass format-table for null-textures We directly look up in the format arrays here to save indirections. But do you know what's even faster than a single indirection? Assigning a compile-time constant! So let's use the newly available pack-helper to pack directly what we want here.
