Hello,
On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 2.9.0 release. This release contains 2300+ commits from 199
authors.
You can grab the tarball from our download page here:
http://www.qemu.org/download/#source
The full list of changes are available at:
http://wiki.qemu.org/ChangeLog/2.9
Highlights include:
* I/O-polling support for virtio-blk (and virtio-scsi experimentally), which
can improve I/O-heavy workloads by as much as 10-20%
* Core support for MTTCG (multi-threaded TCG emulation), now enabled by
default for Alpha and ARM on x86 machines
* Hardware-acceleration support for x86 guests on Windows via HAXM
* Hotplug and HMAC algorithm support for virtio-crypto devices
* vhost support for virtio-pci devices behind a guest IOMMU
* Many stability fixes for XHCI emulation
* Significant security improvements and I/O throttling support for
virtfs/virtio-9p
* Texinfo documentation for all QMP commands and events
* Postcopy migration can now by used for guests using hugetlbfs-backed memory
* ARM: support for MTTCG (see above)
* ARM: support for hardware RNG, BCM2835 SD card controller, and GPIO
controller when emulating Raspberry Pi board.
* MIPS: support for MIPS Boston board on MIPS64EL
* Nios2: Initial support for Nios-II R1 boards, emulating 10M50 development
kit with Nios2 GHRD loaded in the FPGA
* OpenRISC: Lots of fixes and new instructions
* PowerPC: support for many new POWER9 instructions via TCG emulation, new
"40p" machine type, and pseries support for H_SIGNAL_SYS_RESET hypercall
* s390: support for multiple buses for zPCI, virtio-crypto, and booting via
network.
* SPARC: rewritten support for Niagara
* Tricore: support for many additional instructions
* x86: support for 5-level paging under TCG emulation, caching mode support
for emulation guest IOMMU, and SMI feature negotiation for q35 machines.
* Xtensa: support for -icount
* and lots more...
Thank you to everyone involved!
