Hi, Yes ANV will need something like this as well. If the GPU samples from both an ASTC5x5 texture and one with an aux buffer without a texture cache invalidate between such accesses, then the GPU hangs, which in turn makes the system unresponsive for a few seconds until the kernel resets the GPU; then an ioctl will fail in i965 which means things are very bad usually and (for me atleast on my system with how I build mesa) the application crashes.

Presumably anv needs something like this too? What happens if you have a single draw which samples from both an ASTC5x5 texture and one with an aux buffer?
