vga optimization (Glauber Costa)
Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.
In this patch, we map the linear frame buffer as RAM,
make sure it has dirty region tracking enabled, and then
just let the region to be written.

e1000 VLAN offload emulation (Alex Williamson)
We're currently ignoring the e1000 VLAN tagging, stripping and filtering
features in the e1000 emulation. This patch adds backing for the
relevant registers and provides a software implementation of the
acceleration, such that a guest can make use of VLANs.
This is mostly (only?) useful for a guest on a bridge (not user mode
networking). The only caveat beyond that is that you need to make sure
the host NIC isn't doing it's own tagging, stripping, or filtering.
This generally means the host NIC on the bridge should not be part of a
VLAN.

Fix media detection on emulated CDROM (Gary Grebus)
This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen
when running a variety of Linux guests: the desktop GUI shows a CDROM
device as present, but is unable to automount the media and display its
contents.
The patch adds the PLAY_AUDIO capability bit to the data returned by
MODE_SENSE commands. That convinces the guest kernel to determine what
kind of media is present.
Arguably Linux could be smarter about this, but it's my guess there are
few (if any) hardware CDROM drives that don't set the bit, and there are
a large number of Linux distros that exhibit this problem.

gdbstub: manage CPUs as threads (Jan Kiszka)
This patch enhances QEMU's built-in debugger for SMP guest debugging.
Using the thread support of the gdb remote protocol, each VCPU is mapped
on a pseudo thread and exposed to the gdb frontend. This way you can
easy switch the focus of gdb between the VCPUs and observe their states.
On breakpoint hit, the focus is automatically adjusted just as for
normal multi-threaded application under gdb control.
Furthermore, the patch propagates breakpoint and watchpoint insertions
or removals to all CPUs, not just the current one as it was the case so
far. Without this, SMP guest debugging was practically unfeasible.

than entered meaning that there is currently no way to enter x509

Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier).
After going through the debug log and scratching my head for quite some
time. I found the following:
The problem was with this block move:
lsi_scsi: SCRIPTS dsp=
0fae8e50 opcode
01000028 arg
00f63c40
lsi_scsi: DMA addr=0x00f63c40 len=36
The number of bytes to be transferred (len) should be 40 which corresponds
to the block transfer of length 0x28 (from opcode
01000028). Instead we
have a length of 36 (0x24). The code responsible for this is (in
'lsi_do_dma'):
if (count > s->current_dma_len)
count = s->current_dma_len;
Basically we're overwriting the length 40 with the value 36 which I
think we just left over in that variable from an earlier transfer. In my
patch below I initialize s->current_dma_len to s->dbc before we begin
the DMA transfer during Data In phase.
The attached patch gets Openserver 5.0.5 past the hardware detection
(and it lists the hard drive to boot, woohoo). It appears to stop a
little while later (doesn't seem SCSI related), but it's been so long since
I've booted Openserver I'm not sure what's supposted to happen after the HW
detection using the boot/root disks.
Props go to Craig Ringer for the initial post and the code that he posted
some of which is in this patch.

Fix -linux-user build by reverting r5701
Unfortunately, -linux-user doesn't use osdep as it replaces some of those

remain in place so instead of introducing a qemu_getpagesize() let's just
use getpagesize() in the non-Windows implementation of qemu_vmalloc.

sockets: switch over tcp/telnet/unix serial line to new helper functions (Gerd Hoffman)
This switches the tcp, telnet and unix socket support for character
devices (serial/parallel, ...) to the new socket helpers. Thereby they
gain IPv6 support and also get ability to search for a free tcp port.
Syntax is the same as for vnc, using a to= option, like this:
-serial tcp:localhost:5000,to=5099,server
This will check the 5000 -> 5099 port range (inclusive) for a free tcp
port. Likewise you can get auto-allocated unix sockets by specifying an
empty path:
-serial unix:,server
qemu will create a randomly named socket in $TMPDIR then.
tcp also got new "ipv4" and "ipv6" options to make qemu try only the
specified internet protocol version.
You can use the "info chardev" command added by the first patch in this
series to figure the tcp port / unix socket actually allocated.

It adds support IPv6 support and for automatically allocating an unused

the upper limit for the display number to try. Scanning is started at
the display number given in the display specification, i.e. this command
line:
-vnc localhost:7,to=11

There are also new "ipv4" and "ipv6" options to make qemu try only
