[RFC v2 0/4] chip/vgic adaptations for forwarded irq

Eric Auger
2015-02-11T08:23:11Z

This series proposes some fixes that appeared to be necessary
to integrate IRQ forwarding in KVM/VFIO.

- deactivation of the forwarded IRQ in irq_disabled case
- a specific handling of forwarded IRQ into the VGIC state machine.
- deactivation of physical IRQ and unforwarding on vgic destruction
- rb_tree lock in vgic.c

Integrated pieces can be found at
ssh://git.linaro.org/people/eric.auger/linux.git
on branch irqfd_integ_v9

v1 -> v2:
- change title of the series (formerly "vgic additions for forwarded irq")
- "[RFC 4/4] KVM: arm: vgic: handle irqfd forwarded IRQ injection
before vgic readiness" now handled in ARM irqfd series
- add chip.c patch file

Eric Auger (4):
chip.c: complete the forwarded IRQ in case the handler is not reached
KVM: arm: vgic: fix state machine for forwarded IRQ
KVM: arm: vgic: add forwarded irq rbtree lock
KVM: arm: vgic: cleanup forwarded IRQs on destroy
