Hi,
I am currently doing some benchmarks using virtio-net-device using
virtio-mmio (non PCI) with qemu_system_arm with KVM. Purpose is to
compare with device passthrough performance.
I heard about the availability of a multi-queue option that greatly
improves the performance but I currently fail

in practice KVM_CAP_IRQFD_RESAMPLE seems to be always enabled
as soon as kernel has HAVE_KVM_IRQFD so the resamplefd check
may be unnecessary.

This patch removes all DPRINTF and replace them by trace points.
A few DPRINTF used in error cases were transformed into error_report.

- __func__ is removed since trace point name does the same job
- HWADDR_PRIx were replaced by PRIx64
Besides those changes
This patch serie replaces direct settings of kvm_irqfds_allowed
by actual checks of the KVM_CAP_IRQFD extension. Also A new
kvm_resamplefds_enabled() enables to check KVM_CAP_IRQFD_RESAMPLE.
in the second patch file the vfio device is the first user of
kvm_resamplefds_enabled().
