[PATCH 19/35] kvm: x86: Prepare kvm_get_mp_state for in-kernel irqchip

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

This code path will not yet be taken as we still lack in-kernel irqchip
support. But qemu-kvm can already make use of it and drop its own
mp_state access services.
