Sahan Fernando	fd6a536c60	Kernel: Implement basic VirGL device ... This commit flips VirtIOGPU back to using a Mutex for its operation lock (instead of a spinlock). This is necessary for avoiding a few system hangs when queuing actions on the driver from multiple processes, which becomes much more of an issue when using VirGL from multiple userspace process. This does result in a few code paths where we inevitably have to grab a mutex from inside a spinlock, the only way to fix both issues is to move to issuing asynchronous virtio gpu commands.	2022-03-09 14:58:48 +03:30
