Subject: [Qemu-devel] [PATCH 0/3] dataplane: misaligned buffers support for Windows guests
Date: Thu, 10 Jan 2013 17:48:18 +0100 [thread overview]
Message-ID: <1357836501-15555-1-git-send-email-stefanha@redhat.com> (raw)
Windows guests do not work with x-data-plane=on because misaligned request
support is missing in hw/dataplane/virtio-blk.c. This series adds a bounce
buffer when the request is misaligned. Windows guests now work with
x-data-plane=on.
Stefan Hajnoczi (3):
block: make qiov_is_aligned() public
dataplane: extract virtio-blk read/write processing into do_rdwr_cmd() dataplane: handle misaligned virtio-blk requests
