2011-01-31raw-win32: Fix bdrv_flush return valueKevin Wolf
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-01-31qed: Images with backing file do not require QED_F_NEED_CHECKStefan Hajnoczi
The consistency check on open is necessary in order to fix inconsistent table offsets left as a result of a crash mid-operation. Images with a backing file actually flush before updating table offsets and are therefore guaranteed to be consistent. Do not mark these images dirty.

2011-01-31qcow2: Add bdrv_discard supportKevin Wolf
This adds a bdrv_discard function to qcow2 that frees the discarded clusters. It does not yet pass the discard on to the underlying file system driver, but the space can be reused by future writes to the image.

2011-01-31virtio-pci: Disable virtio-ioeventfd when !CONFIG_IOTHREADStefan Hajnoczi
It is not possible to use virtio-ioeventfd when building without an I/O thread. We rely on a signal to kick us out of vcpu execution. Timers and AIO use SIGALRM and SIGUSR2 respectively. Unfortunately eventfd does not support O_ASYNC (SIGIO) so eventfd cannot be used in a signal driven manner. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Acked-by: Michael S.

2011-01-31block: add block_resize monitor commandChristoph Hellwig
Add a monitor command that allows resizing of block devices while qemu is running. It uses the existing bdrv_truncate method already used by qemu-img to do it's work. Compared to qemu-img the size parsing is very simplicistic, but I think having a properly numering object is more useful for non-humand monitor users than having the units and relative resize parsing. For SCSI devices the new size can be updated in Linux guests by doing the following shell command: echo > /sys/class/scsi_device/0:0:0:0/device/rescan For ATA devices I don't know of a way to update the block device size in Linux system, and for virtio-blk the next two patches will provide an automatic update of the size when this command is issued on the host.

2011-01-29mc146818rtc: update registers after a format changeAurelien Jarno
For some unknown reason, the MIPS kernel briefly changes the RTC to binary mode during boot, switch back to BCD mode and read the time. As the registers are updated only every second, they may still be in the old format when they are read. This patch forces a register update immediately after a format change (BCD/binary or 12/24H). This avoid long fsck during boot due to time wrap. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-29escc: fix interrupt flagsAurelien Jarno
Recent PowerPC kernel end up in kernel panic during boot in -nographic mode. In this mode the second serial port is used as the udbg console, and thus a few characters are sent on this port. This activates the tx interrupt flag, and later choke the Linux kernel, as it was not expecting such a flag to be set. The problem here comes from the fact that contrary to most devices the interrupt flags are only set if the interrupt is enabled. Quoting the datasheet: "If the corresponding IE bit is not set, the IP for that source of interrupt will never be set." This patch fixes that by enabling the interrupt flag only when the corresponding interrupt is enabled. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-25pulseaudio: process 1/4 buffer max at onceGerd Hoffmann
Limit the size of data pieces processed by the pulseaudio worker threads. Never ever process more than 1/4 of the buffer at once. Background: The buffer area currently processed by the pulseaudio thread is blocked, i.e. the main thread (or iothread) can't fill in more data there. The buffer processing time is roughly real-time due to the pa_simple_write() call blocking when the output queue to the pulse server is full. Thus processing big chunks at once means blocking a large part of the buffer for a long time. This brings high latency and can lead to dropouts. When processing the buffer in smaller chunks the rpos handling becomes a problem though. The thread reads hw->rpos without knowing whenever qpa_run_out has already seen the last (small) chunk processed and updated rpos accordingly. There is no point in reading hw->rpos though, pa->rpos can be used instead. We just need to take care to initialize pa->rpos before kicking the thread.
