IMHO that mesa change is not valid. It is settings its affinity to run on all threads which is definitely *NOT* something we want to be allowed. Management applications want to control which CPUs QEMU runs on, and as such Mesa should honour the CPU placement that the QEMU process has.

This is a great example of why QEMU wants to use seccomp to block affinity changes to prevent something silently trying to use more CPUs than are assigned to this QEMU.
