Hi!
We're currently having issues while trying to make the KVM in-kernel
lapic to work. There seems to be a KVM_SET_LAPIC ioctl() for this but
it's not documented in Documentation/kvm/api.txt. Are there other
ioctls we should know about? We're using KVM_CREATE_IRQCHIP obviously.
Plenty, yes.
KVM_IRQ_LINE - raise or lower an irq line.
KVM_GET_IRQCHIP/KVM_SET_IRQCHIP - save/restore PIC/IOAPIC states.
KVM_CREATE_PIT2/KVM_GET_PIT2/KVM_SET_PIT2 - PIT support (optional)
KVM_IRQ_LINE_STATUS - like KVM_IRQ_LINE, but provide information about
whether the interrupt was coalesced or not. Useful for compensating for
time drift.
KVM_SET_GSI_ROUTING - manipulate the routes between irq lines and the
IOAPIC and PIC; also maintain virtual routes for message signalled
interrupts (MSI)
KVM_IRQFD - raise an edge-triggered interrupt via an eventfd; useful for
talking to a guest from outside its host process
KVM_GET_LAPIC/KVM_SET_LAPIC - save/restore local APIC register state
I'll post documentation patches. To get started, KVM_SET_LAPIC is
simple - it simply accepts a 1K buffer that maps 1:1 to local APIC
registers as documented in the Intel SDM, volume 3.
