Understood.
Knowing if a qxl
driver is in use is an important piece of information.
Libqblock was placed in new directory ./libqblock, libtool will build
dynamic library there, source files of block layer remains in ./block.
So block related source code will generate 3 sets of binary, first is old
ones used in qemu, second and third are non PIC and PIC ones in ./libqblock.

Outside the safety of the global mutex we need to poll on file
descriptors. I found epoll(2) is a convenient way to do that, although
other options could replace this module in the future (such as an

The IOQueue has a pool of iocb structs and a function to add new
read/write requests. Multiple requests can be added before calling the
submit function to actually tell the host kernel to begin I/O. This
allows callers to batch requests and submit them in one go.
The actual I/O is performed

Add presave/postload hooks to the ARM GIC common base class.
These will be used by the KVM in-kernel GIC subclass to sync
state between kernel and userspace when migrating.

When using an in-kernel GIC with KVM, we need to tell the kernel where
the GIC's memory mapped registers live. Do this by registering a
MemoryListener which tracks where the board model maps the A15's
private peripherals, so we can finish the GIC initialisation
when the GIC is actually mapped.
This commit adds the ARM KVM headers. This is not to go to QEMU
upstream -- the correct path there is that the KVM code will be
committed to a mainline upstream kernel, and then upstream QEMU
can do a bulk header update from the upstream kernel, which will
allow us to drop this temporary commit.

Add support for saving and restoring VFP register state from the
kernel. This includes a check that the KVM-created CPU has full
VFP support (as the TCG Cortex-A15 model always does), since for
the moment ARM QEMU doesn't have any way to tweak optional features
on created CPUs.
