[Qemu-devel] [PATCH 02/21] specs/qcow2: do not use wording 'bitmap header'

A bitmap directory entry is sometimes called a 'bitmap header'. This patch leaves only one name - 'bitmap directory entry'. The name 'bitmap header' creates misunderstandings with 'qcow2 header' and 'qcow2 bitmap header extension' (which is extension of qcow2 header) Signed-off-by: Vladimir

[Qemu-devel] [RFC 0/3] aio: experimental virtio-blk polling mode

Recent performance investigation work done by Karl Rister shows that the guest->host notification takes around 20 us. This is more than the "overhead" of QEMU itself (e.g. block layer). One way to avoid the costly exit is to use polling instead of notification. The main drawback of polling is

[Qemu-devel] [RFC 1/3] aio-posix: add aio_set_poll_handler()

Poll handlers are executed for a certain amount of time before the event loop polls file descriptors. This can be used to keep the event loop thread scheduled and may therefore recognize events faster than blocking poll(2) calls. This is an experimental feature to reduce I/O latency in high IOPS
