Author: Lucas Stach <[email protected]> Date: Mon Nov 7 14:22:21 2022 +0100 etnaviv: fix late Z with MSAA active On RA_WRITE_DEPTH GPUs the RA stage needs to be told that MSAA is active when the PE Z/S stage is needed. Not sure what it does exactly, but this fixes broken late Z on those GPUs when performing MSAA rendering.
