[PATCH v5 0/5] KVM: irqfd consumer based on IRQ bypass manager

From: Eric Auger
Date: Mon Aug 10 2015 - 09:32:01 EST

This series transforms irqfd into an IRQ bypass consumer and
introduce the infrastructure shared by Intel posted-interrupts
and ARM forwarded IRQ series.

The bypass manager gets compiled for x86 and arm/arm64 when
KVM is used. A new kvm_irqfd.h header is created to externalize
some irqfd declarations going to be used by architecture specific
code. A new CONFIG_HAVE_KVM_IRQ_BYPASS option is introduced
to enable architecture specific IRQ manager hooks.

the series depends on the IRQ bypass manager:

Best Regards



v4 -> v5:
- remove kvm_arch static inline stubs
- add pr_info on registration failure

v3 -> v4:
- fix compilation for arm/arm64
- rearrange signoffs/history on some patch files

v2 -> v3 (Feng Wu):
- rebase on IRQ bypass manager [PATCH v2] virt: IRQ bypass manager:
- Correct some minor errors and typo
- Add something needed for posted-interrupts

v1 -> v2:
- isolate the bypass manager and irqfd consumer in this series
- take into account Paolo's comments and use container_of strategy and
remove additional fields introduced in v1.
- create kvm_irqfd.h
- add unregistration in irqfd_shutdown

v1: originally part of [RFC 00/17] ARM IRQ forward control based on IRQ
bypass manager (https://lkml.org/lkml/2015/7/2/268)

Eric Auger (4):
KVM: arm/arm64: select IRQ_BYPASS_MANAGER
KVM: create kvm_irqfd.h
KVM: introduce kvm_arch functions for IRQ bypass
KVM: eventfd: add irq bypass consumer management
