./wip/qemu, CPU emulator using dynamic translation

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ]


Branch: CURRENT, Version: 1.1.0, Package name: qemu-1.1.0, 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
and cross-debugging.

Changelog:
System emulation
All targets

    qdev properties of type hex8 and hex32 used to accept hexadecimal values not \ 
prefixed with "0x"; the prefix is mandatory starting with this \ 
version. These properties are: iobase, membase, io_base for all devices that \ 
support the properties; vram_size for sysbus-g364 and SUNW,tcx; version for sb16 \ 
and iommu; ctl_iobase and data_iobase for fw_cfg; readback for debugcon; \ 
elcr_addr and elcr_mask for i8259.
    PCI addresses can still be addressed with a pair of hexadecimal device and \ 
function without a "0x" prefix.
    -kernel, -initrd and -append are now aliases for suboptions of -machine (for \ 
example -machine kernel=foo), and as such they are also available with \ 
-readconfig.
    PCI-to-PCI bridges are supported [...]
    PCI emulation includes a standard hot-plug controller [...]
    The coroutine backend can now be configured using configure \ 
--with-coroutine=.... A new coroutine backend sigaltstack is available for \ 
platforms that don't support the default ucontext backend.
    Last but not least: the SDL user interface now uses the new QEMU icon. 

ARM

    The syborg machine type has been removed since the Symbian Virtual Platform \ 
is no longer relevant with the disbanding of Symbian.
    A device tree can be passed to the kernel using -dtb option (or \ 
alternatively -machine dtb=...).
    New 'nuri' and 'smdkc210' models of Samsung Exynos4210 based devboards.
    New 'highbank' model of the Calxeda Highbank.
    New 'vexpress-a15' model of the Versatile Express Cortex-A15. 

PowerPC

    The Bamboo machine now works with TCG, before only KVM was able to execute \ 
440 code.
    Pseries handles PCI, allowing for virtio devices with -M pseries.
    Pseries works with PR KVM allowing for -M pseries -enable-kvm to work on G5s.
    We can now emulate e500mc cores, but no e500mc based board is emulated yet. \ 
You need to use -M mpc8544ds and a special guest kernel.
    Timers on ppc405 now work and don't segfault QEMU. 

S/390

    Added support to -kernel to allow booting of ELF binaries.
    Fixed -kernel to allow booting of newer guest kernels.
    Devices can now be hotplug add'ed (remove is not there yet).
    Rebooting a virtual machine now works. 

SPARC

    Added interrupt controller and support of vector interrupts.
    Fixed handling 32 bit instructions on a sparc64 CPU.
    Fixed block load instructions regression happened in 1.0 release.
    Fixed BCD mask in m48t59 emulation, so that Solaris 2.5.1 doesn't hang on \ 
sun4m emulation when day of month >21.
    Fixed initrd loading in qemu-system-sparc64. 

x86

    NMIs are correctly injected through the LAPIC (rather than sent directly to \ 
the guest CPU) and respect the LINT1 mask, thus fixing kdump.
    The -rtc-td-hack option is now available as a qdev property (-global \ 
mc146818rtc.lost_tick_policy=slew) and as such can be specified in a -readconfig \ 
configuration file.
    When the system is suspended to RAM, QEMU will now stop executing the guest \ 
until a wakeup event occurs. Implemented wakeup events include key presses, \ 
mouse button presses, RTC alarm, ACPI timer expiration, serial console input \ 
(off by default; enable with -global isa-serial.wakeup=1), and the system_wakeup \ 
monitor command.
    KVM can optionally use kernel-based emulation of the local APIC, IOAPIC, \ 
i8259 PIC and i8254 PIT. This is supported with the -machine \ 
...,kernel_irqchip=on command-line option. MSI is not supported yet when using \ 
the kernel_irqchip option.
    Emulation of a PC System Flash device. The feature is enabled by adding a \ 
pflash drive. This feature is not supported when KVM is enabled. See Features/PC \ 
System Flash for more information.
    KVM guests support Hyper-V enlightenments. These are enabled by the -cpu \ 
features hv_spinlocks, hv_relaxed and hv_vapic. 

Device emulation

    The virtio-scsi device is now supported by QEMU. The guest driver will be \ 
supported in Linux starting at version 3.4.
    QEMU now includes experimental support for USB 3.0 (xHCI).
    Various improvement on the floppy emulation, most notably media change has \ 
been fixed 

Audio devices

    Audio devices can now use volume control capabilities exposed by the \ 
PulseAudio and Spice backends. (Note: all audio devices do not expose their \ 
volume control unless --enable-mixemu is turned on). 

Block devices

    QEMU's NBD client implementation and the qemu-nbd server both fully support \ 
asynchronous I/O.
    The rbd block driver supports the discard operation now
    The vpc block driver supports the Fixed Disk subformat of VHD images now
    The new QMP command transaction can be used to perform a set of multiple \ 
snapshots atomically, rolling back to the original images if there is a problem \ 
along the way. See Features/SnapshotsMultipleDevices for more information.
    The new monitor command block_stream lets guest copy data from the backing \ 
file to the current image while the guest is running. This lets users enables \ 
quick provisioning of new virtual machines using shared remote storage, and lets \ 
the guest transition incrementally to fast local storage. An alternative to \ 
streaming is the copy-on-read option of the -drive command-line option, which \ 
only transfers data when the guest needs it.
    An experimental extension of the qcow2 file format has been introduced. With \ 
the implementation as of QEMU 1.1, the most important addition is zero clusters, \ 
which allows image streaming and copy-on-read to leave images sparse if the \ 
backing file they are copying from is sparse. In order to enable the extension, \ 
use qemu-img create -f qcow2 -o compat=1.1 <filename> <size> for \ 
creating the image. Note that older versions of QEMU won't be able to read such \ 
images.
    I/O throttling is experimentally supported using the new -drive options \ 
bps/bps_rd/bps_wr/iops/iops_rd/iops_wr. It is expected to work with virtio-blk \ 
and IDE harddisks, but may lead to hangs when used with CD-ROM or floppy \ 
emulation or other devices.
    qemu-io supports new options to enable tracing and to choose a cache modes 

Network devices

    QEMU supports a new type of network device, bridge (used with -net bridge or \ 
-netdev bridge). The new type is similar to tap, but uses a helper program \ 
instead of a script to attach the device to a bridge. The helper program can \ 
then be installed as setuid. The helper program supports a simple ACL and \ 
configuration mechanism, see the commit message and feature page for \ 
documentation. 

Live Migration, Save/Restore

    Live migration (or save/restore) from QEMU releases prior to 0.13 to QEMU \ 
1.1 is not supported.
    Live migration supports IPv6. IPv6 addresses can be expressed as \ 
tcp:host:port. Brackets around a numeric host address are required if a port is \ 
also specified, otherwise they can be omitted. 

Guest agent

    qemu-ga has been ported to Windows.
    Interfaces added for suspending guests to disk/ram, and retrieving \ 
information about network interfaces
    Interfaces for filesystem freeze have been hardened, and no longer depend on \ 
guest agent runtime state to determine whether a system is currently frozen.
    An easier to use reset mechanism has been added: guest-sync-delimited. 

Host support

    ARM hosts are now supported again (they were broken in 1.0).
    Sockets and SLIRP on Windows hosts was broken in 0.14 and works again.
    64-bit Windows hosts are now supported. 

User-mode emulation

    User-mode emulation can provide some information from the /proc filesystem.
    On 64-bit hosts user-mode emulation now defaults to reserving 0xf7000000 \ 
bytes of address space for the guest. This significantly reduces the likelihood \ 
of QEMU having to fail a guest mmap() request when there is still memory \ 
available. This reservation can be overridden with the -R command line option. 

Testing

    A make check target has been implemented and runs some quick sanity tests
    qemu-iotests, which was previously hosted in an external git repository, has \ 
been merged into the QEMU source tree 

Build dependencies

    Building QEMU requires glib 2.12 on POSIX systems, and glib 2.20 on Win32 \ 
systems.

General

    i386-softmmu is no longer named qemu but instead referred to as \ 
qemu-system-i386 for better consistency with other targets. A new tool is likely \ 
to be introduced that uses the qemu name so distributions are advised to not \ 
undo this change.
    QEMU now uses a separate thread for VCPU execution. This merges the biggest \ 
difference between the qemu-kvm tree and upstream QEMU.
    A new memory dispatch API has been added internally. A new monitor command \ 
"info mtree" can show the hierarchy of memory regions in the guest.
    QEMU now has a build dependency on glib and makes extensive use of glib.
    QEMU now can run on more hosts. Hosts without a native code generator can \ 
use the TCG interpreter (TCI). See Features/TCI for more information. 

Block devices (disks)

    QEMU now supports I/O latency accounting in the monitor command "info \ 
blockstats".
    Errors are now tracked per device and are shown by the monitor command \ 
"info block".
    All image formats now support asynchronous operation. IDE and SCSI emulation \ 
will use this feature, while other devices (notably floppy and SD) will not. 

IDE/ATAPI

    A large number of bugs were fixed regarding CD media change and tray locking. 

SCSI

    Memory management errors could crash QEMU when scsi-disk encountered I/O \ 
errors. Many instances of this problem were fixed.
    The accuracy of error handling for SCSI emulation has been greatly improved.
    SCSI devices can now be addressed by channel, target (id) and LUN. Not all \ 
emulated HBAs will support this feature (in particular, the LSI controller will \ 
not).
    Block device pass through is now supported through a new scsi-block device. \ 
The scsi-block device works with block devices (like /dev/sda or /dev/sr0) \ 
rather than /dev/sgN devices, and is more efficient because it does not consume \ 
arbitrary amounts of memory when the guest does large data transfers.
    SCSI CD-ROMs now report media changed events.
    SCSI CD-ROMs now support DVD images.
    Bugfixes for IDE media change also apply to SCSI.
    SCSI devices now report a unit attention condition when the system is \ 
started or reset. This may cause problems with old firmware versions. 

VDI

    Now supports discarded blocks in dynamically-sized images. 

User-mode networking (SLIRP)

    SLIRP can process ARP replies and gratuitous ARP requests from the guest. 

ARM

    QEMU now supports the new Cortex-A15 instructions in linux-user mode (via \ 
"-cpu any"): VFPv4 fused multiply-accumulate (VFMA, VFMS, VFNMA, \ 
VFNMS) and also integer division (UDIV, SDIV).
    The vexpress-a9, versatileab, versatilepb and realview-* boards now have \ 
audio support.
    QEMU is known not to work on ARM hosts in this release. (ARM target \ 
emulation is fine.) 

pSeries

    sPAPR VIO devices can now be created with -device. 

Xtensa

    QEMU now supports DC232b and FSF xtensa CPU cores.
    QEMU now supports sim (similar to Tensilica ISS) and LX60/LX110/LX200 machines. 

Migration

    QEMU now supports live migration using image files like QCOW2 on shared storage
