[igt-dev] [PATCH i-g-t v2 06/13] lib: Fork gen9_media.h

Wed Oct 4 03:10:16 UTC 2023


Fork gen9_media.h from gen8_media.h with the gen9 definitions that were
in that header and with a new struct gen9_surface_state. Although the
surface state is the same as for gen8, the meaning of at least mocs is
different. As a follow up the mocs definition will change for gen9 and
above.
