/qemu, CPU emulator using dynamic translation
2.0.0, Package name:
qemu-2.0.0, Maintainer: pkgsrc-users
QEMU is a FAST! processor emulator using dynamic translation to achieve
good emulation speed, QEMU has two operating modes:
* Full system emulation. In this mode, QEMU emulates a full system
(for example a PC), including a processor and various peripherals.
It can be used to launch different Operating Systems without rebooting
the PC or to debug system code.
* User mode emulation (Linux host only). In this mode, QEMU can launch
Linux processes compiled for one CPU on another CPU. It can be used
to launch the Wine Windows API emulator or to ease cross-compilation

All onboard buses now have distinct names, so that all of them can be reached \
with "-device bus=...". As a result of this, some buses that used to \
have duplicates got renamed:
i2c-bus.0 to i2c-bus.1 for machines n800, n810;
virtio-mmio-bus.0 to virtio-mmio-bus.3 for vexpress-a15, vexpress-a9;
virtio-mmio-bus.0 to virtio-mmio-bus.31 for virt;
usb-bus.0 to usb-bus.1 for xilinx-zynq-a9, fulong2e;
ide.0 to ide.1 for isapc, mips, g3beige, mac99, prep;
This change requires care when doing migration from 1.x to 2.x QEMU; you need to \
specify bus=NEW explicitly on the destination for devices on the renamed bus.
Another bus rename is pci to pci.0 for pseries. This does not require as much \
care on migration; if you were specifying "bus=pci" explicitly, QEMU \
will not start unless you change that to "bus=pci.0".
qemu-system-arm no longer defaults to the obsolete "integratorcp" if \
no machine is specified on the command line (this was a recurring source of \
confusion). Users with existing integratorcp images will need to add "-M \
integratorcp" to the command line if it is not already present.
Future incompatible changes
Three options are using different names on the command line and in configuration \
file. In particular:
The "acpi" configuration file section matches command-line option \
The "boot-opts" configuration file section matches command-line option \
The "smp-opts" configuration file section matches command-line option \
Starting with QEMU 2.1, -readconfig will standardize on the name fo the command \
Support for "-M virt", a board type that only uses virtio devices
Support for "-cpu host" when running under KVM
Support for new 32-bit mode ARMv8 instructions in TCG
Support for all 64-bit mode ARMV8 user-accessible instructions except for the \
optional CRC and crypto extensions
Support for AArch64 disassembling (requires a C++ compiler to be installed on \
Initial support for KVM on AArch64 systems (some features such as migration are \
not yet implemented)
Support for the Canon PowerShot A1100 DIGIC board using "-M canon-a1100"
Support for the allwinner-a10-based board "-M cubieboard"
Support for flow control in the Cadence UART
"integratorcp" is no longer the default machine (see the 'incompatible \
changes' section above)
Support for Altivec 2.07 and VSX instructions when running under TCG
Support for ISA 2.06 "load/store quadword instructions", "divide \
extended instructions" and "floating-point test instructions" \
when running under TCG
PReP is not anymore (incorrectly) included in qemu-system-ppcemb
Improved support for "-nodefaults" on the pSeries machine. Display \
devices created with "-device VGA" will be handled correctly in the \
Support for boot order in pSeries emulation
Support for adapter interrupts in virtio-cc2
Support for Sun CG3 framebuffer with the Sun4m machine. The CG3 framebuffer can \
be requested with "-vga cg3".
Support for the CASA compare-and-swap instruction in TCG.
On the Q35 machine, the HPET interrupt can now be attached to GSIs 16-23, like \
on real hardware.
The Q35 machine now supports CPU hotplug.
Two flash chips can be specified using the "-drive if=pflash" or \
"-pflash" options twice.
Memory layout has changed slightly; to improve performance, the PIIX4 machine \
("-M pc") now has 3GB of low memory instead of 3.5GB if the guest has \
more than 3.5GB of memory. Similarly, the Q35 machine ("-M q35") now \
has 2GB instead of 2.75GB of low memory if the guest has more than 2.75GB of \
Support for migration of Intel MPX registers.
The Apple SMC device is now exposed in the ACPI tables.
On the PIIX machine, PCI hotplug now supports devices behind a bridge (only for \
bridges not added by hotplug; hot-plugged bridges can still use the PCI Standard \
Support for the Hyper-V reference time counter via the "hv-time" \
suboption of "-cpu". This can improve performance of Windows guests \
substantially for applications that do many floating-point or SIMD operations. \
(Requires KVM and Linux 3.14).
The distributed qemupciserial.inf file now allows installing multiport PCI \
serial devices on Windows too.
ACPI tables generated by QEMU can now be used by OVMF firmware. OVMF starting \
with SVN r15420 is needed. In particular hotplug, pvpanic device and other ACPI \
based features now work for OVMF.
x2apic is now enabled by default when KVM is in use.
PCI passthrough of devices with a ROM now works.
added support for ML605 and KC705 FPGA boards.
Cache-related opcodes now correctly check privilege level/memory accessibility.

Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE= 33 # not yet ported as of x.y.z
PYTHON_VERSIONS_INCOMPATIBLE= 33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.
Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.
Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.
Whitespace cleanups and other nits corrected, where necessary.

Update to 1.7.0, from tsutsui.
The HDA device emulation now includes a mixer by default.
Previously this had to be enabled with the configure argument
"--enable-mixemu" when building QEMU.
Audio will work correctly on systems without OSS (/dev/dsp).
On previous versions, those systems needed special arguments
to "configure" for audio to work out of the box.
Audio honors the QEMU_AUDIO_TIMER_PERIOD environment variable
and has less CPU utilization by default than previous versions.
Support for the LSI 53C810 SCSI HBA, which unlike the 895A is
supported on some very old Windows NT versions.
VFIO now supports setting CPU affinity on MSI interrupts.
VFIO can now reset assigned devices much more reliably using
either PCI function-level reset (FLR), power management, or a
reset (done by the kernel) of the parent bridge.
Several improvements to the reliability of using option ROMs
for devices that are assigned with VFIO.
Performance and functionality improvements for USB 3.0.
Can now specify an initrd on the command line.
PowerPC now supports the dump-guest-memory command.
The "nmi" command will trigger a crash dump from kdump, using
a RESTART interrupt.
The SCLP line-mode console ("operating system messages") can
be accessed with "-device sclplmconsole".
ACPI tables can be generated by QEMU and can be used by firmware
directly. This will in the future enable new features without
modifications of all firmware components (SeaBIOS, OVMF,
Initial support for supporting more than 1TB of RAM (but firmware
does not yet support this).
Xen HVM domains can now resume from suspend-to-RAM (S3) state.
Subcommands (like "info block") can now autocomplete their
Help for a single subcommand can be printed with a monitor
command such as "help info block".
New commands "blockdev-snapshot-internal-sync",
"blockdev-snapshot-delete-internal-sync" improve support for
internal qcow2 snapshot.
New command "blockdev-add" provides a QMP interface for block
The throttling algorithm has been rewritten; the new code is
more robust, and supports configuration of separate limits for
sustained I/O vs. I/O bursts
Migration was broken from QEMU <= 1.5 to 1.6; the new release
M68K ColdFire emulation supports atomic system calls.
Block devices, qemu-img, qemu-io
The sheepdog driver supports automatic reconnect after network
The VMDK driver supports files produced by VMWare ESX.
The qcow2 driver can detect some cases of corruption, and will
prevent writing to a corrupted image.
The VHDX driver supports creating and writing .vhdx images.
The metadata of a file (where each sector of the guest image
is stored in the file on the host) can be dumped in human-readable
or JSON format using a new command "qemu-img map".
The "filesystem freeze/thaw" commands are now supported on
Windows too, where they will invoke the native Volume Shadow
Copy Service (VSS).
For targets that have no embedded disassembler, QEMU will now
produce hexadecimal dumps instead of just emitting an error
when a disassembly is requested. The enclosed script disas-objdump.pl
can be used, together with an external objdump program, to
convert the dump to a readable disassembly.
TCG now runs on x32 hosts.
On Win32, QEMU must be compiled with --disable-coroutine-pool
to work around a suspected compiler bug.
The GTK terminal windows (monitor, serial console, parallel,
...) are still unusable in TCG mode: they lose characters and
can raise deadlocks.
