[Qemu-devel] [PATCH v5 0/4] irqfds for s390x

[Cornelia Huck]

Hi,

here's the next version of my patchset implementing irqfds for s390x.
This has been reworked to make use of flic methods; in order to make
this work, the flic had to be split into a kvm part (which basically
offers the same functionality as the 'old' flic) and a non-kvm part
(which basically does nothing).

Changes from v4:
- capability helpers are already upstream
- use flic methods for I/O adapter registration and mapping
- move direct interaction with the routing code from virtio-ccw to
  the flic

Also available on

https://github.com/cohuck/qemu.git s390x-irqfd

Please review.

  s390x: split flic into kvm and non-kvm parts
  s390x: Add I/O adapter registration.
  s390x/virtio-ccw: reference-counted indicators
  s390x/virtio-ccw: Wire up irq routing and irqfds.
