Now that vfio ioeventfd support is in v4.17-rc kernels, let's push
forward with this series. I've posted the linux-headers update
separate as it was rather an ordeal with conflicting defines, non-
upstream defines, and inveted types that don't exist. Dependencies
to build this series:
https://lists.gnu.org/archive/html/qemu-devel/2018-05/msg00097.html
Which depends on MST's:
https://lists.gnu.org/archive/html/qemu-devel/2018-04/msg02510.html
The first two patches are unchanged and I've kept previous reviews.
The change to the latter two patches is the addition of trace events
and options for disabling both vfio and KVM ioeventfds. These are
both experimental options which are useful for debugging and
evaluating any performance differences, not intended for support.
Please review. Thanks,
Alex
