The port 'id' or number is internal state between the guest kernel and
our bus implementation. This is invocation-dependent and isn't part of
the guest-host ABI.
To correcly enumerate and map ports between the host and the guest, the
'name' property is used.
Example:
-device virtserialport,name=org.qemu.port.0
This invocation will get us a char device in the guest at:
/dev/virtio-ports/org.qemu.port.0
which can be a symlink to
/dev/vport0p3
This 'name' property is exposed by the guest kernel in a sysfs
attribute:
/sys/kernel/virtio-ports/vport0p3/name
A simple udev script can pick up this name and create the symlink
mentioned above.

Via control channel messages, the guest can tell us whether a port got
opened or closed. Similarly, we can also indicate to the guest of host
port open/close events.

This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.
The virtio console is now a very simple qdev device that sits on the
virtio-serial-bus and communicates between the bus and qemu's chardevs.
This commit also includes a few changes to the virtio backing code for
pci and s390 to spawn the virtio-serial bus.
As a result of the qdev conversion, we get rid of a lot of legacy code.
The old-style way of instantiating a virtio console using
-virtioconsole ...
is maintained, but the new, preferred way is to use
-device virtio-serial -device virtconsole,chardev=...
With this commit, multiple devices as well as multiple ports with a
single device can be supported.
For multiple ports support, each port gets an IO vq pair. Since the
guest needs to know in advance how many vqs a particular device will
need, we have to set this number as a property of the virtio-serial
device and also as a config option.
In addition, we also spawn a pair of control IO vqs. This is an internal
channel meant for guest-host communication for things like port
open/close, sending port properties over to the guest, etc.
This commit is a part of a series of other commits to get the full
implementation of multiport support. Future commits will add other
support as well as ride on the savevm version that we bump up here.

VIRTIO_PCI_QUEUE_MAX is redefined in hw/virtio.c. Let's just keep it in
hw/virtio.h.
Also, bump up the value of the maximum allowed virtqueues to 64. This is
in preparation to allow multiple ports per virtio-console device.

gone (and so is BDRV_O_ACCESS). Default value for bdrv_flags (0/zero) is READ-ONLY. Need to explicitly request READ-WRITE.
Instead of using the field 'readonly' of the BlockDriverState struct for passing the request,

This patch adds a new property named 'ver' to scsi-disk which allows to
specify the version which the virtual disk/cdrom should report to the
guest. By default this is the qemu version (i.e. 0.12). usage:
-drive if=none,id=disk,file=...
-device lsi
-device scsi-disk,drive=disk,bus=scsi.0,unit=0,ver=42
You can also switch the version for all scsi drives using:
-global scsi-disk.ver=42

When using a control/QMP monitor in tandem with a regular monitor, asynchronous
messages can get lost depending on the order of the QEMU program arguments.
QEMU events issued by monitor_protocol_event() always go to cur_mon. If the
user monitor was specified on the command line first (or it has ,default), the
message will be directed to the user monitor (not the QMP monitor).
Additionally, only one QMP session is currently able to receive async messages.
To avoid this confusion, scan through the list of monitors and emit the message
on each QMP monitor.

Since commit 747bbdf7 QEMU_WARN_UNUSED_RESULT is never defined as it is
conditional on a define from config-host.h which is included only later.
Include that file earlier to get the warnings back.
Reactivating it unfortunately leads to some warnings about unused qdev_init
results. These calls are changed to qdev_init_nofail to avoid build failures.

When a disconnection happens the client's socket on QEMU
side may become invalid, this way it won't be possible
to query it to get client information, which is going to
be needed by the future QMP VNC_DISCONNECTED event.
To always have this information available we query the
socket at connection time and cache the client info in
struct VncState.
Two function are introduced to perform this job.
vnc_client_cache_addr() is called right when the connection
is made, however the authentication information is not
available at that moment so vnc_client_cache_auth() is
called from protocol_client_init() to get auth info.

Handling of transmit commands is rather complex,
so about 80 lines of code were moved from function
action_command to the new function tx_command.
The two new values "tx" and "cb_address" in the
eepro100 status structure made this possible without
passing too many parameters.
In addition, the moved code was cleaned a little bit:
old comments marked with //~ were removed, C++ style
comments were replaced by C style comments, C++ like
variable declarations after code were reordered.
Simplified mode is still broken. Nor did I fix
endianess issues. Both problems will be fixed in
additional patches (which need this one).

consequently 5 gentoo users have hit the breakage and were kind enough
to report, so thank you:

But above all thanks to Toralf Foerster who actually provied enough

According to pages 9-31 - 9-34 of "SuperSPARC & MultiCache Controller
User's Manual":
1. "A lower priority fault may not overwrite the
MFSR status of a higher priority fault."
2. The MFAR is overwritten according to the policy defined for the MFSR
3. The overwrite bit is asserted if the fault status register (MFSR)
has been written more than once by faults of the same class
4. SuperSPARC will never place instruction fault addresses in the MFAR.
Implementation of points 1-3 allows booting Solaris 2.6 and 2.5.1.

The existing P_REXB internal opcode flag unconditionally emits
the REX prefix. Technically it's not needed if the register in
question is %al, %bl, %cl, %dl.
Eliding the prefix requires splitting the P_REXB flag into two,
in order to indicate whether the byte register in question is
in the REG or the R/M field. Within TCG, the byte register is
in the REG field only for stores.
