This adds some tiny overhead to vcpu entry. You could remove it by
using the vcpu->requests mechanism to clear the flag, since
vcpu->requests is already checked on every entry.
So IIUC, let's have request bit for indicating PLE,
pause_interception() /handle_pause()
{
make_request(PLE_REQUEST)
vcpu_on_spin()
}
check_eligibility()
{
!test_request(PLE_REQUEST) || ( test_request(PLE_REQUEST)&&
dy_eligible())
.
.
}
vcpu_run()
{
check_request(PLE_REQUEST)
I know check_request will clear PLE_REQUEST, but you just need a
clear_request here, right?
Yes. tried to use check_request for clearing. But I ended up in
different implementation. (latest thread)
