Guest driver sets repeat rate and delay time by KBD_CMD_SET_RATE,
but ps2 backend doesn't process it and no auto-repeat implementation.
This patch adds support of auto-repeat feature.
Guest ps2 driver sets autorepeat to fastest possible in reset,
period: 250ms, delay: 33ms

Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
third release candidate for the QEMU 1.5 release. This release is meant
for testing purposes and should not be used in a production environment.
http://wiki.qemu.org/download/qemu-1.5.0-rc2.tar.bz2
You can help improve
Indicate ASPM L0s and L1 support in Link Capabilities and make the ASPM
bits in Link Control writable. These Link Control bits don't do anything
in qemu, but having them writable means the BIOS or OS can write them as
on real hardware.

Most threads will use mutexes and other sleeping synchronization primitives
(condition variables, semaphores, events) periodically. For these threads,
the synchronization primitives are natural places to report a quiescent

- lots of documentation
There is plenty of docume
This includes a (mangled) copy of the urcu-qsbr code from liburcu.
The main changes are: 1) removing dependencies on many other header files

futexes in synchroni

From: Dietmar Maurer
backup_start() creates a block job that copies a point-in-time snapshot
of a block device to a target block device.
We call backup_do_cow() for each write during backup. That function
reads the original data from the block device before it gets
overwritten. The data is then

Start a point-in-time copy of a block device to a new destination. The
status of ongoing drive-backup operations can be checked with
query-block-jobs where the BlockJobInfo.type field has the value 'backup'.
The operation can be stopped before it has completed using the
block-job-ca
Note: These patches apply to my block-next tree. You can also grab the code
from git here:

This series adds a new QMP command, drive-backup, which takes a point-in-time
snapshot of a block device. The snapshot is copied out to a target block

The QMP 'transaction' command keeps a list of in-flight transactions.
The transaction state structure is called BlkTransactionStates even
though it only deals with a single transaction. The only plural thing

The bdrv_add_before_write_cb() function installs a callback that is
invoked before a write request is processed. This will be used to
implement copy-on-write point-in-time snapshots where we need to copy
out old data before overwriting it.

This patch adds a transactional version of the drive-backup QMP command.
It allows atomic snapshots of multiple drives along with automatic
cleanup if there is a failure to start one of the backup jobs.
Note that QMP events are emitted for block job completion/cancellation
and the block job will b
