| Thread-topic: | cpu ops |
In current approach, we have cpu ops like eoi/set_tpr/get_tpr,/set_itm
/set_kr0/set_kr2.../set_kr7 etc.
I think there is another simple alternative is to simply export
setreg/getreg
for cpu ops.
The benefit of this could be:
1: Simple in pv_ops I/F
2: hypervisor neutral. Today we only virtualize around 15 AR/CR
read/write,
But future it may extends since different Hypervisor may do in
different way.
Do u like to see this one happen?
thanks, eddie
