[Mesa-dev] [PATCH 19/19] etnaviv: GC7000: Split off current texture code
Wladimir J. van der Laan
laanwj at gmail.com
Mon Oct 30 16:17:05 UTC 2017
Prepare for two texture handling paths, the descriptor-based
path will be added in a future commit. These are structured
so that the texture implementation handles its own state
emission.
