Practically speaking, "report" causes a lot of issues when encountering a host
ENOSPC error.  Switch to "enospc" as the default werror semantics.  All host
errors other than ENOSPC will be reported to the guest.  ENOSPC will cause the
VM to stop.  Asynchronous notifications are needed to inform management tools
that some action should be taken but stopping the VM is at least better than
undefined behavior in the guest.

When the CPU is in little endian mode, it should load values from RAM
in byte swapped manner. This check is in all the ld and st functions,
but misspelled in gen_qemu_ld32s.

Resent with fixed formatting.

This patch adds two new command line options:
 -chroot <dir>
 -runas <user>

This is useful for running qemu as an unprivileged user in a chroot
jail.  To avoid having to populate the jail, chrooting happens right
before the start of guest execution.

After doing a video to video copy, cirrus_do_copy() in cirrus_vga.c does a
conditional call to cirrus_invalidate_region() with an "if (!notify)" test.
However at this point the blt has already been done so it seems like this call
should be made unconditionally.  The patch below fixes some display update

Avoid repeated creation/initalization/destruction of attr and calls to

Broadcast was used so that the I/O threads would wakeup, reset their
ts values and all but one go to sleep, in other words an optimization
to prevent threads from exiting in presence of continuing I/O
activity. Spurious wakeups make the looping around cond_timedwait with
ever reinitialized ts potentially unsafe and as such ts in no longer
reinitilized inside the loop, hence switch to signal is warranted and
this benefits of this particlaur optimization are lost.

(It's worth noting that timed variants of pthread calls use realtime
clock by default, and therefore can hang "forever" should the host
time be changed. Unfortunatelly not all host systems QEMU runs on
support CLOCK_MONOTONIC and/or pthread_condattr_setclock with this
value)

KVM uses cpu_physical_memory_rw() to access the I/O devices. When a
read or write with a length of 8-byte is requested, it is split into 2
4-byte accesses.

This has been broken in revision 5849. After this revision, only the
first 4 bytes are actually read/write to the device, as the target
address is changed, so on the next iteration of the loop the next 4
bytes are actually read/written elsewhere (in the RAM for the graphic
card).

This patch fixes screen corruption (and most probably data corruption)
with FreeBSD/amd64. Bug #2556746 in KVM bugzilla.

cirrus_do_copy() in hw/cirrus_vga.c seems to make some incorrect assumptions
about video memory layout.  It tries to convert addresses to coordinates
assuming that one row of data is (width * depth) bytes long.  The correct way
seems to be to use the pitch fields in the CirrusVGAState structure instead.

Without this patch, I get lots of screen corruption when I try to drag a window
under X as it's passing the wrong coordinates to the display surface for the
copy.  With this patch I can drag a window with no screen corruption.
