4.2.0:
System emulation
----------------
Incompatible changes
On s390x, using KVM now explicitly requires a host kernel version of at least 3.15 (which includes the 'flic' KVM device). This had been broken since QEMU 2.10 already.
On s390x, migration of KVM guests with >8TB of memory from pre-4.2 QEMUs will no longer work. Migration of KVM guests with up to 8TB of memory continues to work, as will migration of >8TB guests from QEMU 4.2 on.
The "autoload" parameter of the "block-dirty-bitmap-add" QMP command has been removed (it's no longer needed).
New deprecated options and features
The "ide-drive" device is deprecated. Users should use 'ide-hd' or "ide-cd" as appropriate to get an IDE hard disk or CD-ROM as needed.
The "change" QMP command has been deprecated. Use "blockdev-change-medium" or "change-vnc-password" instead.
The "migrate_set_downtime", "migrate_set_speed" and "migrate-set-cache-size" QMP commands have been deprecated. Use "migrate-set-parameters" instead.
The "query-migrate-cache-size" QMP command has been deprecated. Use "query-migrate-parameters" instead.
The "scsi-disk" device is deprecated. Users should use 'scsi-hd' or "scsi-cd" as appropriate to get a SCSI hard disk or CD-ROM as needed.
Consult the "Deprecated Features" appendix for the full list of historically deprecated features/options.
68k
Added new "next-cube" machine for emulating a classic NeXTcube (still incomplete, can only boot to the firmware prompt)
Added new "q800" machine for emulating Macintosh Quadra 800 (can only boot Linux, MacOS ROM is not yet supported)
Arm
Added Aspeed AST2600 SoC and evaluation board model support
QEMU's Arm semihosting implementation now supports v2.0 of the specification, including the "STDOUT_STDERR" and "EXIT_EXTENDED" extensions
We now correctly support more than 256 CPUs when using KVM
The virt board now supports memory hotplugging, when used with a UEFI guest BIOS and ACPI.
The raspberry PI models now implement the bcm2835 system timer device and a dummy thermal sensor.
Performance of the TCG emulation of ARM cores has been improved.
SVE is supported in KVM guests (requires SVE hardware and kernel support)
MIPS
Fixed bug involving emulation of ST.W instruction in system mode only (there was no bug in Linux user mode).
PowerPC
Behavior for unplug of multifunction PCI devices has been changed to match x86. Attempting to unplug any function will cause an unplug of the whole slot.
There are now separate machine types for POWER8 based and POWER9 based non-virtualized machines (powernv8 & powernv9).
Default RAM size for powernv machines has been increased to 1.75G which should allow more things to work with the default parameters.
RTAS (runtime firmware) code is now supplied by SLOF (boot time firmware) instead of by qemu itself. This won't affect users in most cases, but will affect users of -bios which bypasses SLOF, which includes kvm-unit-tests. You'll need a sufficiently recent version of kvm-unit-tests to handle this.
mffsce, mffscrn and mffscrni POWER9 instructions now supported in TCG
powernv machine now includes models for the Homer and OCC SRAM system devices
"info pic" HMP command now reports whether the irq chip is emulated in kernel or in qemu
pseries machine type no longer permits NUMA nodes with no CPU and no memory - this was already unlikely to work due to problems expressing this configuration to the guest
On pseries-4.2 and later machine types, "vsmt" is set to be equal to smp_threads by default (previously it was different in some circumstances for compatibility with old KVM versions)
New defaults mean that with the pseries machine type and host kernels prior to 4.13 you may get errors about VSMT mode. You can either update your host kernel or work around this by setting -machine vsmt=8.
RISC-V
The `-initrd` argument is now supported.
The debugger can now see all architectural state regardless of the currently executing privilege mode on each hart.
The sifive_u board now contains additional memory regions that more closely match the board.
s390
TCG now implements IEP (Instruction Execution Protection), a CPU feature introduced with the z14. Until the "qemu" CPU model is lifted to a z14, it can be enabled using the "max" CPU model ("-cpu max").
SPARC
The sun4u IOMMU now support the "invert endianness" bit
x86
VMX features can be enabled/disabled via the "-cpu" flag.
When nested virtualization is enabled with an option like "-cpu Haswell,+vmx", the set of VMX features will also be constrained to what was available on the corresponding CPU model.
New "microvm" machine type that has virtio-mmio instead of PCI, and no ACPI support (so no hotplug too). The new machine type is meant as a baseline for performance optimizations of QEMU, firmware and guests. While inspired by Firecracker it is not entirely compatible with it (for example it does not have Firecracker's userspace IP stack and MicroVM Metadata Service).
Support for AVX512 BFloat16 extensions.
New CPU models: Denverton (a server-class Atom-based SoC), Snowridge, Dhyana
New CPU features clzero and xsaveerptr
Latest version of all CPU models now have TSX (HLE and RTM) disabled by default
Support for new IA32_ARCH_CAPABILITIES flags: MDS_NO, TSX_NO, TSX_CTRL
macOS Hypervisor.framework support ("-accel hvf") is now considered stable
Xtensa
Add new "virt" machine.
Device emulation and assignment
ACPI
ARM machines can use the ACPI generic event device for the system powerdown event
Audio
Audio devices support an "audiodev" property that can be used to choose a specific backend to connect to the device.
Block devices
Unmap operations are now accounted and visible in the output of "query-blockstats"/"info blockstats"
Graphics
Support for more ati-vga registers
IPMI
UUID handling for the built-in IPMI BMC has changed. Before the UUID was set from the qemu UUID, if that was set. However, in a real system, the UUID of a BMC will be independent of the system UUID. So now the UUID must be explicitly set for a BMC if you want one. Otherwise the BMC will not have a UUID. To set the UUID of a BMC, use the new property guid=11223344-5566-7788-99aa-bbccddeeff00 for the ipmi-bmc-sim device.
New PCI interfaces for IPMI KCS and BT devices are available. The devices pci-ipmi-kcs and pci-ipmi-bt are used to choose these devices.
Network devices
Support for network failover for easier migration of VFIO devices.
VFIO
vfio-pci supports the "failover_pair_id" property for easier migration of VFIO devices.
virtio
virtio-mmio now supports the virtio standard compatible v2 personality (still defaulting to the legacy v1 personality for compatibility reasons)
Support for virtio 1.1 packed virtqueues.
9pfs
the "local" backend now has a new 'multidevs' option to deal with cross-device setups (ie. when the shared directory spans over multiple devices on the host)
Character devices
Any backend that supports connection as a socket client (NBD, chardev, network device, monitor...) can now request to use TCP keep-alive with the server.
Crypto subsystem
With new enough gcrypt or nettle libraries, QEMU can now use the library's own XTS cipher mode code. This provides a potentially huge performance boost for AES-XTS encryption, which benefits the LUKS disk encryption block driver I/O performance.
Monitor
Fix not to leave the monitor wedged when the client disconnects while the queue is full, and the event timing is unlucky.
QMP
query-machines now report the default CPU type for each machine
Migration
The 'validate-uuid' migration compatibility checks the UUID matches on migration, preventing accidental migration of the wrong VM to the wrong destination. (Yury Kotov)
Network
The user mode host network backend now allows to set a guest-visible DNS address which is not in the virtual network, unless restrict mode is enabled.
Block device backends and tools
Block drivers can now support BDRV_REQ_PREFETCH for more efficient handling of copy-on-read requests; the NBD driver has wired this up to NBD_CMD_CACHE.
The LUKS block driver supports falloc/full preallocation.
The NBD server now advertises NBD_FLAG_CAN_MULTI_CONN on shared readonly connections.
The NBD server and client support the new NBD_CMD_FLAG_FAST_ZERO as an optimization during the copying of sparse images.
The backup block job now creates a filter node, just like mirror and commit do. Clients that care about the structure of the block graph need to take this into account.
Several assertion failures relating to the use of an NBD server with iothreads have been fixed.
Creation of an NBD client now allows an optional 'reconnect-delay' parameter, which can be used to reconnect rather than permanently fail in the face of a transient server hiccup.
NBD client and server now permit export names up to 4k in length (rather than 256 bytes), while at the same time being more careful to avoid over-long strings in violation of the NBD protocol.
Miscellaneous
bugs in gdbstub handling of F and ! packets have been fixed
The arguments to -kernel and -initrd are now mmap-ed for some targets. This allows sharing memory when many VMs are loaded with the same arguments.
User-mode emulation
Xtensa
call0 ABI may be selected for the user emulation with command line option -xtensa-abi-call0 (or with QEMU_XTENSA_ABI_CALL0 environment variable).
TCG
---
tcg tests are now in $BUILDDIR/tests/tcg/$TARGET/ (rather than $BUILDDIR/$TARGET/tests/)
new TCG Plugins feature allows instrumentation experiments to be written
Build Information
-----------------
Python
The minimum supported version of Python is now 3.5.
Container Based Builds
The docker.py tooling now supports podman containers [1] as an alternative to docker
the docker.py now requires python3 to run
a number of the cross compiler containers have been updated to Buster
Build Dependencies
The minimum version of the glib library is now 2.48
0.82.24
- FDC emulation now allows READ command to look for
sector numbers that are out of range in order to
support booter games that read out of range sector
numbers as part of their copy protection.
- Windows SDL1 window resizing fixed to avoid snapping
and jumping issues when the window is sized down
to the point the menu bar doubles or triples in
height due to menu item wrapping.
- FDC clear DMA terminal count automatically (with a
warning printed to the log) at beginning of FDC
read/write (PC-98 booter game Star Cruiser).
- FDC DMA read/write failure now causes FDC to signal
an error, and the debug output will say so.
- FDC debug output now shows motor bits in the correct
order, not backwards
- CONFIG.COM and MIXER.COM are now registered only at
DOS kernel startup, to resolve their disappearance
after RE-DOS or guest system reset.
- Some OpenGL cleanup and fixes for when compiling for
Mac OS X Catalina.
- Shell startup now prints the actual mapper binding
(whatever it is) for the Host key instead of assuming
F12/F11.
- "Ro" key in PC-98 mode in the mapper interface now
clarifies that it is Ro / _ since the shift state is
the underscore.
- Shell startup code fixed to show F11 for Windows and
F12 for other platforms properly instead of always
showing F11.
- Added BOOT option --pc98-graphics to start up with
graphics layer enabled in order to run HDI images
using QMOUSE and games that expect NEC MOUSE.COM
behavior of showing graphics layer on driver init.
- BOOT now hides graphics layer on startup in PC-98 mode
to reflect real hardware.
- INT 33h mouse emulation now enables graphics layer
on mouse startup and INT 33h AX=0 to imitate NEC
MOUSE.COM behavior seen on real PC-98 hardware. This is
needed for some Orange House games that assume this
behavior, without which the graphics are invisible.
- INT 33h define range functions now include separate
range correction for text mode vs graphics mode.
- Help sections in Configuration GUI have been improved,
they are now easier to browse and read. (aybe)
- CONFIG: added description for 'securemode' (aybe).
- Integer properties are now correctly saved when
they have been changed in configuration GUI (aybe).
- Some scenarios with command history could display
garbage characters from previous/next command (aybe).
- Fixed all hard disk images created by IMGMAKE having
VHD footers. (Allofich)
- Windows Visual Studio solution: (aybe)
- cleaned and clarified project properties for projects
- removed configurations that didn't make sense
- fixed broken debugging
- consolidated to use single versions of SDK and IDE
- enabled faster builds (multi-processor compilation)
- fixed broken builds, e.g. ARM, ARM64
Changes in FS-UAE Launcher 3.0.2
Another fix for global WHDLoad quit key.
Fixed a misleading warning when cyberstorm ROM was not found (3.0.1).
Changes in FS-UAE 3.0.1:
Fix video scaling when restoring from fullscreen on Windows.
Changes in FS-UAE Launcher 3.0.1:
Scanner bug prevented Conquests of the Longbow WHDLoad to be recognized.
The correct kickstart wasn’t always loaded.
Cloanto ROMs were not always decrypted.
Fix for global WHDLoad quit key.
6.0 to 6.0.1: (June 5, 2019)
* Added support for CDFJ bankswitching type (Galaga, Wizard of War, etc).
* Allow the DPC+ scheme to not enable playfield 'jitter' effect for
certain older DPC+ driver versions; this allows 'Epic Adventure' ROM
to finally work in Stella.
-Have fun!
A wild MAME 0.215 appears! Yes, another month has gone by, and it’s
time to check out what’s new. On the arcade side, Taito’s incredibly
rare 4-screen top-down racer Super Dead Heat is now playable!
Joining its ranks are other rarities, such as the European release
of Capcom‘s 19XX: The War Against Destiny, and a bootleg of Jaleco’s
P-47 – The Freedom Fighter using a different sound system. We’ve
got three newly supported Game & Watch titles: Lion, Manhole, and
Spitball Sparky, as well as the crystal screen version of Super
Mario Bros. Two new JAKKS Pacific TV games, Capcom 3-in-1 and Disney
Princesses, have also been added.
Other improvements include several more protection microcontrollers
dumped and emulated, the NCR Decision Mate V working (now including
hard disk controllers), graphics fixes for the 68k-based SNK and
Alpha Denshi games, and some graphical updates to the Super A'Can
driver.
We’ve updated bgfx, adding preliminary Vulkan support. There are
some issues we’re aware of, so if you run into issues, check our
GitHub issues page to see if it’s already known, and report it if
it isn’t. We’ve also improved support for building and running on
Linux systems without X11.
0.214:
With the end of September almost here, it’s time to see what goodies
MAME 0.214 delivers. This month, we’ve got support for five more
Nintendo Game & Watch titles (Fire, Flagman, Helmet, Judge and
Vermin), four Chinese computers from the 1980s, and three Motorola
CPU evaluation kits. Cassette support has been added or fixed for
a number of systems, the Dragon Speech Synthesis module has been
emulated, and the Dragon Sound Extension module has been fixed.
Acorn Archimedes video, sound and joystick support has been greatly
improved.
On the arcade side, remaining issues in Capcom CPS-3 video emulation
have been resolved and CD images have been upgraded to CHD version
5, Sega versus cabinet billboard support has been added to relevant
games, and long-standing issues with music tempo in Data East games
have been worked around.
0.213:
It's really about time we released MAME 0.213, with more of everything
we know you all love. First of all, we’re proud to present support
for the first Hegener + Glaser product: the “brikett” chess computers,
Mephisto, Mephisto II and Mephisto III. As you can probably guess,
there’s an addition from Nintendo’s Game & Watch line. This month
it’s Mario’s Bombs Away. On a related note, we’ve also added
Elektronika’s Kosmicheskiy Most, exported as Space Bridge, which
is an unlicensed total conversion of the Game & Watch title Fire.
If you haven’t played any of the handheld LCD games in MAME, you’re
missing something special – they look superb with external scanned
and traced artwork.
On the arcade side, we’ve added The Destroyer From Jail (a rare
Philko game), and alternate regional versions of Block Out and
Super Shanghai Dragon’s Eye. The CD for Simpsons Bowling has been
re-dumped, resolving some long-standing issues. With its protection
microcontroller dumped and emulated, Birdie Try is now fully
playable. Protection microcontrollers for The Deep and Last Mission
have also been dumped and emulated. Improvements to Seibu hardware
emulation mean Banpresto’s SD Gundam Sangokushi Rainbow Tairiku
Senki is now playable, and sprite priorities in Seibu Cup Soccer
have been improved.
In computer emulation, two interesting DOS compatible machines
based on the Intel 80186 CPU are now working: the Mindset Personal
Computer, and the Dulmont Magnum. The Apple II software lists have
been updated to include almost all known clean cracks and original
flux dumps, and the Apple II gameport ComputerEyes frame grabber
is now emulated. We’ve received a series of submissions that greatly
improve emulation of the SWTPC S/09 and SS-30 bus cards. On the
SGI front, the 4D/20 now has fully-working IRIX 4.0.5 via serial
console, and a whole host of improvements have gone into the Indy
“Newport” graphics board emulation. Finally, MAME now supports HDI,
2MG and raw hard disk image files.
GNS3 is a graphical network simulator that allows you to design complex
network topologies. You may run simulations or configure devices ranging from
simple workstations to powerful Cisco routers. It is based on Dynamips, an IOS
emulator which allows users to run IOS binary images from Cisco Systems and
Pemu, an PIX firewall emulator based on Qemu.
Upstream changes:
3.3.1 2019/10/28
* Works better with English keyboard.
* Modified mouse operation on Android. LMB is assigned to popup menu.
* Updated compatible CGROM for PC-6601. Now characters for playng
card suit are properly displayed.
Changes:
- Serial and parallel file output now disable stdio
buffering so that output is more immediately
accessible to the user.
- Added file output to serial port emulation.
- Parallel port emulation now support both dev: and
file: to specify that LPTx output go to a file,
not necessarily a device by name.
- Fixed bug that capped vmemsizekb to 8KB.
- BIOS bootup screen now shows correct text for CPU
type instead of "? CPU" when cputype=auto.
- PC-98 256-color mode fixed to ignore doublescan
and 200-line bits of the GDC to match real hardware
behavior. This fixes display problems with
"Alone in the Dark"
- BOOT command will now always set 640x200 8-color
graphics mode when booting PC-98 disk images,
to match the apparent behavior of real hardware.
- PC-98 hardware apparently allows writing port 6Ah
to jump directly to 256-color mode from 8-color
mode, update DOSBox-X emulation to allow it.
This fixes the PC-9821 port of "Alone in the Dark".
- Slow CGA memory access handler now wraps to 16KB
correctly, and resolves a segfault that can happen
if the last 16KB is accessed by the guest if
vmemsizekb=16.
- vmemsize default is now -1, which means to pick a
video memory size automatically.
- Added PC-98 INT 1Bh AH=03h SCSI BIOS command, which
allows FreeDOS98 to boot.
- INT 33h emulation fixed not to reset mouse min/max
range if the new video mode is a VESA BIOS SVGA
mode (not a standard VGA mode). Some games seem to
define the mouse min/max range AND THEN set the
VESA BIOS mode, not the other way around.
- INT 33h define range functions now apply rounding
to the max range if the range is close to the
dimensions of the screen, for games like Daggerfall
that set the cursor maximum range to values close to,
but not exactly, the dimensions of the VGA screen.
- INT 33h define range functions updated to accept max
ranges for mapping host to guest if set just after
video modeset or if those INT 33h functions are called
when no mouse buttons are down.
- INT 10h AH=4Fh AL=08h (Set DAC width) now correctly
set AL=4Fh to indicate the call is supported.
- VGA DAC palette writes are now ALWAYS masked to 6-bit
unless 8-BIT DAC mode is ON and enabled. This fixes
palette problems with Amulets and Armor.
- VGA DAC 6/8-bit palette management code simplified
- Added dosbox.conf option to instruct DOSBox-X to leave
the PC speaker clock gate enabled if set, for games
that use that PIT output as a time source. Setting
the option to "true" allows "Bàoxiào sānguózhì", a game
with strange and elaborate timing code, to run without
hanging at the second title screen.
- VGA port 3DAh "undefined bits" setting changed to 0x04
to accomodate "Blues Brothers"
- Configuration GUI: If the settings are scrollable,
tabbing between fields will now auto-scroll to the
field and make it visible.
- In the configuration GUI, scroll wheel input no longer
changes the window focus.
- Set CPU cycles dialog box layout fixed.
- Added 'skip encoding unchanged frames' option to
dosbox.conf. If set, AVI video capture will skip
video frame compression if the frame has not changed
from the previous frame. Option is off by default
at this time in case it causes any issues with users
and their video editing software.

CHANGELOG
=========
Yabause 0.9.15
August 24, 2016 - guillaume.duhamel - Release
Following our strict release schedule, here's a new Yabause version.
This new version includes so many new stuff, I cannot list them all.
(If you really want the full list, it's on our repository)
Arguably, the most notable features of this release are:
- Low-level CD Block emulation
- CloneCD file format support
- High resolution for the software renderer
We also included code from other great projects:
- Musashi 68K core (code by Karl Stenerud)
- SSF sound format playing (code by R. Belmont, Richard Bannister, Neil Corlett)
As many of you should already be aware, Yabause was forked into a new project,
uoYabause, by devmiyax. We included some of his fixes back into Yabause.
Due to lack of maintainer, this release will be the last to include a gtk port.
Since our last release, we also improved our tools:
- Automated builds for linux, mac and windows
- Development builds pushed after each commit
- Translations on Transifex
- Compatibility reports on our wiki
And finally, we had to move from Paypal to Patreon
* bump versions to match 8.0 / 9.0_BETA
* Use local directories (NetBSD-daily isn't on ftp.netbsd.org anymore).
Yes, this requires local access to both versions.
* Add detection of .tar.xz sets from "new" version sets
* Overhaul arch-list and machine-lists, add various arm and mips variants
* Add a few comments to hopefully make it easier to grasp what is going on
(according to my best interpretation)
exist in NetBSD 8.0, but which either doesn't exist or exist with a
new major version in NetBSD 9.0_BETA.
The distributions and PLISTs produced by modifying the gencompat.sh
script (will be committed shortly), and running it over the complete
8.0 and 9.0_BETA release binaries.
This package does not attempt to separate out the X11 libraries affected
in a separate compat80-x11 package (since gencompat.sh didn't do it...).
The list of different arm variants is possibly a bit too long, but better
to err on that side than it being too short. The package is otherwise
patterned after the compat61 package.
The motivation is to consider meson as an application, so there is only
one copy on the system, and as a python 3 program, it can build python 2
packages.
