[Qemu-devel] [PATCH 00/12] ehci: tracing, multiqueue, bugfixes.

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series brings a number of improvements for the EHCI host
adapter.

First it makes EHCI use the tracing infrastructure.  Conversion is done
in a bunch of steps to ease review and to improve bisectability in case
regressions show up.  Not all debug messages are converted (yet).

Second EHCI can keep track of multiple queues now and supports multiple
async requests being in flight at the same time.

And as usual a few bug fixes are included too.

please review,
  Gerd
