The test for using movi32 was sub-optimal for TCG_TYPE_I32, comparing a signed 32-bit quantity against an unsigned 32-bit quantity. When possible, use addi+oris for 32-bit unsigned constants.

After attaching the source, we have to remove the reference we hold to it, because we do not hold anymore a pointer to the source. If we do not do this, removing the source will not finalize it and will not drop the "real" I/O watch source. This showed up when backporting the new flow control patches to older versions of QEMU that still used select. The whole select then failed with EBADF (poll instead will reporting POLLNVAL on a single pollfd) and QEMU froze.

In handling float64_muladd, if we end up doing a subtraction of the product and c, and the 128 bit result of this subtraction happens to have its most significant bit in bit 63, we weren't handling this correctly when attempting to normalize to put the most significant bit into bit 126. We would end up doing a right shift by a negative number (undefined behaviour in C) so at best we would return an incorrect result to the guest. MSB in bit 63 has to be handled as a special case separately from MSB in 0..62 and MSB in 63..126. (MSB in 127 is not possible.)

The existing bdrv_co_flush_to_disk implementation uses rbd_flush(), which is sychronous and causes the main qemu thread to block until it is complete. This results in unresponsiveness and extra latency for the guest. Fix this by using an asynchronous version of flush. This was added to librbd with a special #define to indicate its presence, since it will be backported to stable versions. Thus, there is no need to check the version of librbd. Implement this as bdrv_aio_flush, since it matches other aio functions in the rbd block driver, and leave out bdrv_co_flush_to_disk when the asynchronous version is available.

qemu-system-x86_64 -drive file=ssh://hostname/some/image QEMU will ssh into 'hostname' and open '/some/image' which is made available as a standard block device. You can specify a username (ssh://user@host/...) and/or a port number (ssh://host:port/...). You can also use an alternate syntax using properties (file.user, file.host, file.port, file.path). Current limitations: - Authentication must be done without passwords or passphrases, using ssh-agent. Other authentication methods are not supported. - Uses a single connection, instead of concurrent AIO with multiple SSH connections. This is implemented using libssh2 on the client side. The server just requires a regular ssh daemon with sftp-server support. Most ssh daemons on Unix/Linux systems will work out of the box. Signed-off-by: NRichard W.M.

What is the highest addressable sector on an empty CD-ROM? Nothing is addressable so produce an error. This patch prevents a divide-by-zero in ide_set_sector() since s->sectors and s->heads would be 0. Not to mention that a sector=-1 argument would be nonsense. Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024 /dev/cdrom. The LBA bit will be set to 1 though, so the only easy way to go down the ide_set_sector() CHS code path which divides by zero is to comment out the s->select & 0x40 case for testing.
