Hi I found a way to reliably reproduce PFIFO CACHE_ERRORS, but I don't see why. How to reproduce them: 1) Run a couple of glxinfo loops - 3 is usually enough. while [ true ]; do nvgl glxinfo >/dev/null 2>/dev/null; done 2) Run glxgears. 3) If you can't see it now, resize glxgears window or add more glxinfos. Note: you need at least 2 CP...

1ba6113a90a0 removed a lot of the kernel GPU channel, but method 0x128 was important as otherwise the GPU spams us with `CACHE_ERROR` messages.
