Hello All,
I am Prasad Joshi, studying in a UK University. As a part of project in the
University, I have decided to add GPGPU support in the KVM using virtio. There
are two parts of supporting GPU in VM
1. GPU as a Graphics Device
2. GPU as a Parallel Programming Device (GPGPU)
For this
frontend driver suffice?
Thanks and Regards,

Hi All,
I was just going over TODO list on KVM page. In MMU related TODO I saw
only page eviction algorithm currently implemented is FIFO.
Is it really the case? If yes I would like to work on it. Can someone
let me know the place where the FIFO code is implemented?
Thanks and Regards,
Prasad
