Looks accurate to me, in fact, with hugetlbfs it seems like it's doing
exactly what it should do. The non-hugetlbfs case isn't efficient, but
it isn't wrong either.

Since printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited.

Hi,
as mentioned before I have successfully passed a graphics card from a
Linux host to VM using qemu-kvm.
Shortly after starting the VM and before Windows7 initializes the
graphics card, info pci looks like this:
Bus 0, device 4, function 0:
VGA controller: PCI device 1002:6719
36 matches
