Hello
I am new to GPU and GPU virtualization and found that xen support
intel GPU virtualization using XenGT.
I want to know,
1) What are the critical GPU command pass from xen to Dom0?
2) How the Dom0 mediator or xen validate the GPU command which is
passed from domU GPU driver?
3) If one of the domU guest send bad(malicious) command to GPU which
led GPU to bad state. Can Dom0 mediator or xen prevents this kind of
scenario?
As far as I know, there is know mediation to check for the commands. Xen
does audit the target address space, but not GPU commands.
