Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION
the ioctl doesn't actually work yet (except in the Linuxolator), so if
building on FreeBSD assume the sound drivers are new enough if the ioctl
returns the errno it does currently on FreeBSD.

The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder. Sparc
is not such a system. Indeed, the remainder must be computed as
quot = a / b
rem = a - (quot * b)
Split out a tcg_out_div32 function that properly initializes Y
with the extension of the input to 64-bits. Discard the code
that used the 64-bit DIVX on sparc9/sparcv8plus without extending
the inputs to 64-bits. Implement remainders in terms of division
followed by multiplication.

Hi all,
calling vnc_update_client in vnc_refresh might have the unlikely side
effect of setting vd->timer = NULL, if the last vnc client disconnected.
In this case we have to return from vnc_refresh without updating the
timer, otherwise we cause a segfault.

This patch changes the way rom loading via fw_cfg is handled.
Instead of having pc_init1() call a function which passed all
roms to the firmware config we simply pass a pointer to fw_cfg
to the rom loader.
Advantage: loading roms via firmware works also for devices which
are initialized after pc_init1(), i.e. everyting added via -device.

If a PXE client only wants to find out the size of a file, it will
open the file and then abort the transfer by sending a TFTP ERROR packet.
The ERROR packet should cause qemu to terminate the session. If not,
the sessions will soon run out and cause timeouts in the client.
Also, if a TFTP session already exists with same IP/UDP port, it
should be terminated when a new RRQ is received, instead of creating a
duplicate (which will never be used).
A patch for gPXE to send the ERROR packet is also being submitted to
gPXE. Together they resolve slowness/hanging when booting pxegrub from
qemu's internal TFTP server. The patch from Milan Plzik to return
after sending OACK is also required for a complete fix.

sometimes clear all status registers on bus master disable, which loses

machine without indirect buffer support, which is required for 0.10
compatibility, or without hardware checksum support, which is required for 0.11

get_features callback has been modified: it sets non-optional bits, and clears
