[Qemu-devel] [PATCH 0/4] usb attached scsi

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series adds UAS (usb attached scsi) emulation to qemu.  UAS
is a protocol which uses usb3 streams and this is intended to be the
playground when adding full usb3 support to the xhci emulation.  It
turned out to also be a heavy stress test for the ehci emulation, so
this patch series includes a bunch of ehci bugfixes too.

Patch #4 is not ready for merge yet, I still have to think about a
better way to fix the issue described in the commit log.

Reviews & comments are welcome.

cheers,
  Gerd
