Paolo Bonzini	b4a42f8138	hw: move qdev-monitor.o to toplevel directory ... qdev-monitor.c is the only "core qdev" file that is not used in user-mode emulation, and it does not define anything that is used by hardware models. Remove it from the hw/ directory and remove hw/qdev-monitor.h from hw/qdev.h too; this requires some files to have some new explicitly includes.

Stefan Hajnoczi	88807f89d9	dataplane: add virtqueue vring code ... The virtio-blk-data-plane cannot access memory using the usual QEMU functions since it executes outside the global mutex and the memory APIs are this time are not thread-safe. This patch introduces a virtqueue module based on the kernel's vhost vring code. The trick is that we map guest memory ahead of time and access it cheaply outside the global mutex. Once the hardware emulation code can execute outside the global mutex it will be possible to drop this code. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	2013-01-02 15:55:47 +01:00
