0.15.0

Targets

  • New targets added: LatticeMico32 and UniCore32.

ARM

  • Many bugs in Neon and other ARMv6 and ARMv7 instructions have been fixed
  • Floating point instructions now generally handle NaNs and floating point status flags correctly
  • Dummy implementations of cp15 performance counters and cp14 debug registers mean we can boot more recent Linux kernels that probe for these features
  • SA-1110/SA-1100 support has been added
  • New machine models: ARM Versatile Express (machine "vexpress-a9"), Sharp Zaurus SL-5500 (machine "collie")

MIPS

  • Add me

SH4

  • Add me

PPC

  • Add me

s390x

  • Add me

SPARC

  • Sparc32: Improvements to OpenBIOS make Solaris 8 boot possible.
  • Minor Sparc32 and Sparc64 fixes.

Hosts

ARM

  • Support QEMU's host C code being compiled in Thumb mode (as some gccs do by default)

MIPS

  • Add me

IA64

  • Add me

KVM

Common

  • Countless fixes ported over from qemu-kvm, core is now shared with that tree, i.e. has the same quality
  • Pimped up threading model, now fully synchronized with qemu-kvm tree
  • Removed dependency on external kernel headers, all supported KVM features are now built into the binary

x86

  • Paravirtual kvmclock fixes
  • Stable guest TSC across migration
  • Support for SMEP CPU feature
  • Support for VIA CPU features
  • Reworked & fixed MCE support

PPC

  • ...

s390x

  • ...

Devices

IDE / AHCI

  • Add me

SCSI

  • Add me

USB

  • Add me

virtio

  • Add me

virtio-serial

  • Various fixes for hot-unplug of ports
  • Disallow generic ports at id 0: port number 0 is reserved for console ports for backward compatibility; '-device virtserialport,nr=0' is now not allowed.
  • Allow re-use of a chardev after a port using it gets unplugged
  • Add trace events

PCI/PCI Express

  • Add me

Sound

  • Add me

Video

  • Add me

RTC

  • MC146818 (for PCs): Follow host clock resets to the past immediately (instead of freezing the clock)

Block Layer

  • Added missing -drive options to the man page

Block Drivers

qcow2

  • Add me

qed

  • Support for growing images with qemu-img resize (commit)
  • Periodically flush and clear need check bit to reduce chance of leaving image files dirty on power failure (commit)
  • Fix consistency check on 32-bit hosts (commit)

CDROM Emulation

  • Many fixes to comply with ATAPI specification
  • GET_EVENT_STATUS_NOTIFICATION: Implement 'media' subcommand that helps report tray open/close, media present/absent states to guests. Newer Linux guests (kernels 2.6.38+) rely on this command to revalidate discs.
  • Major code refactoring and cleanup

Networking

User space (slirp)

  • Fixed DHCP support in restrict (host-only) mode
  • Ping packet forwarding to external hosts via unprivileged ICMP sockets of Linux 3.0

Spice

  • Add me

QMP / Monitor

  • Support for two new QMP commands: inject-nmi (commit) and snapshot-blkdev-sync (commit)
  • Fixed some issues with the JSON parser (several commits, first one here)
  • Added the guest agent (commit)

Tracing

  • Make simpletrace.py a Python module for trace analysis scripts (blog), (commit)
  • Make 'simple' backend thread-safe (commit)
  • Add tracetool --probe-prefix optional argument to prefix DTrace probe names (commit)

Linux-user

  • Added support for ppoll, sched_{g,s}etaffinity, epoll, pselect6, prlimit64 syscalls
  • Add s390x and unicore32 linux-user targets
  • Numerous bugfixes

New build dependencies (mandatory and optional)

  • glib-2.0 (mandatory)

Other stuff
