We have a capability enquire system that allows user space to ask kvm whether a feature is available. The point behind this system is that we can have different kernel configurations with different capabilities and user space can adjust accordingly. Because features can always be non existent, we can drop any #ifdefs on CAP defines that could be used generically, like the irq routing bits. These can be easily reused for non-IOAPIC systems as well. Signed-off-by: Alexander Graf <agraf@suse.de> --- include/uapi/linux/kvm.h | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-)
