pkgsrc/emulators/qemu: Makefile PLIST distinfo
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 "acpitable";
The "boot-opts" configuration file section matches command-line option "boot";
The "smp-opts" configuration file section matches command-line option "smp".
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'
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 device tree.
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"
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 overall memory.
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 Hot-Plug Controller).
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
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.
