@Update to 5.2.0
Changelog:
IMPORTANT NOTE: in this release we have switched our build system to internally use Meson. Building should be broadly unchanged for most users, but please see the [[#Build Information|Build Information]] section of the changelog for details and for '''the list of new [[#Build Dependencies |build dependencies]] you now need to install'''.
== System emulation ==
=== Incompatible changes ===
=== New deprecated options and features ===
Consult the [https://www.qemu.org/docs/master/system/deprecated.html "Deprecated Features"] chapter of the QEMU System Emulation User's Guide for the full list of historically deprecated features/options.
In particular, note that the Unicore32 and lm32 guest support have been deprecated and will be removed in a future version. They are now only built if explicitly enabled in --target-list.
=== 68k ===
=== Alpha ===
=== Arm ===
* ARMv8.2 FEAT_FP16 (half-precision floating point) is now implemented for AArch32 emulation (AArch64 already supported this)
* AArch64 BTI is now supported in linux-user emulation mode (it was already implemented for system emulation)
* The SMMUv3 model now supports SMMUv3.2 range invalidation
* The sbsa-ref board now has an embedded controller model for guest powerdown and reboot requests
* The sbsa-ref board now has an SBSA-compatible generic watchdog device
* The Raspberry Pi boards now emulate the CPRMAN clock manager device
* Support for KVM on 32-bit host CPUs (deprecated in 5.0) has now been removed. (32-bit KVM guests on 64-bit hosts remain supported.)
* Two new board models in the mps2 family: mps2-an386 (Cortex-M4 based) and mps2-an500 (Cortex-M7 based)
* New board models in the raspi family: raspi3ap (the Pi 3 model A+), raspi0 (the Pi Zero) and raspi1ap (the Pi A+)
* New Nuvoton iBMC board models: npcm750-evb, quanta-gsj
* The 'max' CPU now implements a 48-bit physical address size when using TCG emulation.
* The 'virt' board supports kvm-steal-time (enabled by default for virt-5.2 and on) so that a guest OS can account for time when its CPUs were not running due to the host not scheduling the corresponding vCPU threads.
=== AVR ===
=== HPPA ===
* Added power button emulation
* Boots NetBSD
* Boots old Linux CDs, e.g debian-0.5 and debian-0.6.1
* Artist framebuffer fixes when running dtwm on HP-UX
* Artist graphics allows screen resolution up to 2048 x 2048 pixels
* fw_cfg interface added
=== Microblaze ===
=== MIPS ===
=== Nios2 ===
=== OpenRISC ===
=== PowerPC ===
* The pseries machine now respects the nvdimm= machine option (previously NVDIMMs could be attached even with nvdimm=off)
* The pseries machine now does a better job of reflecting the user specified NUMA distances in the guest (PAPR limitations mean it's still a pretty poor approximation, though)
* We now fail more gracefully if attempting to run an HPT guest as a nested KVM guest (which isn't supported in the kernel for now)
* spapr_vscsi should now properly report that it does not support hotplug
* The pnv machine now allows firmware images up to 16MiB, instead of just 4 MiB (this matches the limit on physical FSP machines)
=== Renesas RX ===
=== Renesas SH ===
=== RISC-V ===
* Improvements to the Ibex (OpenTitan) PLIC
* OpenSBI v0.8 included by default
* Generic OpenSBI platform used when no -bios argument is supplied
* Support for a noMMU Linux kernel with the `-kernel` option
* A dummy L2 cache controller for the sifive_u is now included
* Support for the SiFive OTP device
* PMPCFG CSR setting bug fixed for RV64
* Improvements to the floating point helpers
* Experimental Hypervisor support updated to v0.6.1 and bug fixes
* Support for NUMA sockets on Virt and Spike Machines
* Support for the Microchip PolarFire SoC Icicle Kit
* Fix for crash seen when running 'poweroff' command on virt machine
* virt and sifive_u machines allow a custom dtb argument
* Support for migrating machines
=== s390 ===
* KVM: The diagnose 0x318 instruction is now supported.
* TCG: More instructions that were introduced with the z14 are now emulated.
* zPCI: vfio-pci devices now report real hardware features for functions, instead of emulated values (needs host kernel support.)
* virtiofs is now also supported on s390x via ccw
=== SPARC ===
* sun4m: fix panic when booting NetBSD with the TCX framebuffer
* sun4u: fix for sabre PCI IRQs being lost due to memory overflow
=== TileGX ===
=== Tricore ===
=== x86 ===
* A new KVM feature which improves the handling of asynchronous page faults is available with ''-cpu ...,kvm-async-pf-int''. This requires Linux 5.8.
=== Xtensa ===
* DFPU coprocessor with single and double precision floating point opcodes is now supported
* NMI is now supported
=== Device emulation and assignment ===
==== ACPI ====
==== Audio ====
==== Block devices ====
==== Graphics ====
==== Input devices ====
==== IPMI ====
==== Network devices ====
==== NVDIMM ====
==== NVMe ====
* Add support for mandatory features of version 1.3 of the NVM Express specification
* Add support for the Abort, Asynchronous Event Request and Get Log Page commands
* Add support for Scatter Gather Lists (supported descriptors: Data Block, Bit Bucket, Segment and Last Segment)
* Allow the device to be configured with the "Admin Only" command set
* Support multiple namespaces through the new nvme-ns device
* The unallocated Intel PCI Vendor and Device ID has been replaced with a QEMU allocated "Red Hat" ID
* Support per-namespace SMART log
==== PCI/PCIe ====
==== SCSI ====
==== SD card ====
==== SMBIOS ====
* The OEM Strings data can now be loaded from a file
==== TPM ====
==== USB ====
==== VFIO ====
==== virtio ====
==== Xen ====
==== fw_cfg ====
==== 9pfs ====
* Significant [https://lists.gnu.org/archive/html/qemu-devel/2020-01/msg05539.html performance improvement of Treaddir] requests.
* A performance warning is now logged on host side if 'msize' is set to a very small value, which especially includes Linux 9P clients not having any user specified 'msize' parameter at all. Simply setting 'msize' (on client/guest side) to any value larger than 8192 will cause the warning to disappear. See [https://wiki.qemu.org/Documentation/9psetup#msize msize documentation] for details.
==== virtiofs ====
* virtiofsd xattrmap option to allow the host to see different xattr names to the guest
* virtiofsd alternate sandbox option for environments where pivot_root isn't available
* virtiofsd 'submount' mechanism (requiring newer guest kernel) allows different host mounts to be seen as separate submounts in the guest, avoiding inode clashes.
==== Semihosting ====
=== Audio ===
=== Character devices ===
* Inverted logic in QAPI handling the "tight" option for abstract UNIX sockets was fixed.
* The QAPI schema now only reports support for abstract UNIX sockets on platforms where it is available (Linux).
=== Crypto subsystem ===
==== experimental qmp interface ====
=== GUI ===
* Spice: add support for SIDE and EXTRA mouse buttons. Improve HiDPI, set physical dimensions of client monitors.
* Build spice and opengl as modules
=== GDBStub ===
=== Host support ===
=== Memory backends ===
=== Migration ===
* A new 'block-bitmap-mapping' migration parameter is added, allowing finer control of which bitmaps to migrate, even when node names differ between source and destination.
* Migration over 'vsock' is now allowed, for nested environments or hosts with hardware that looks like a vsock.
* A new 'calc-dirty-rate'/'query-dirty-rate' call gathers an approximation of the rate at which the guest is dirtying RAM and thus gives an idea about whether precopy migration is likely to proceed.
* The default migration bandwidth has been increased to 1Gbps; users are still encouraged to tune it to their own hardware.
* TLS+multifd is now supported for higher bandwidth encrypted migration.
* Migration with dirty bitmaps has several bugs fixed.
=== Monitor ===
==== QMP ====
* Command block_resize no longer blocks the main loop.
==== HMP ====
* Command block_resize no longer blocks the main loop.
=== Network ===
=== Block device backends and tools ===
* qcow2 files now support extended L2 entries that allow subcluster-based allocation (enable with extended_l2=on when creating the image).
* Using qemu as an NBD client has fewer scenarios where network timeouts stall guest execution
* More explicit errors are reported when use of O_DIRECT fails
* The 'block-export-add' QMP command has been introduced to support qemu-storage-daemon, and replaces the now-deprecated 'nbd-server-add' command.
* The 'vhost-user-blk' export type has been added, allowing qemu-storage-daemon to act as a vhost-user-blk device backend.
* qemu-nbd now supports multiple '-B name' options for exposing multiple dirty bitmaps at once; it also supports a new '-A' option for exposing the new "qemu:allocation-depth" metadata context over NBD.
=== Tracing ===
* Add support of dtrace backend on macOS
=== Miscellaneous ===
* The roms/edk2 submodule and the bundled edk2 binaries have been updated to [https://bugs.launchpad.net/qemu/+bug/1852196 edk2-stable202008].
== User-mode emulation ==
* ppc64abi32-linux-user is deprecated and only built when explicitly enabled in--target-list
* tilegx-linux-user is deprecated and only built when explicitly enabled in--target-list
* better reporting when we can't mmap the guest_base we want on systems without MAP_FIXED_NOREPLACE
== TCG ==
== Guest agent ==
* New commands: guest-get-devices, guest-get-disks & guest-ssh-{get,add,remove}-authorized-keys
* Support guest-get-fsinfo for non-PCI virtio devices, too
== Build Information ==
* The build system is now partly based on Meson. However, building is still done with ''configure'' and ''make'' as in previous versions of QEMU.
* Binaries for emulators are placed in the root build directory, for example as ''qemu-system-ppc'' instead of ''ppc-softmmu/qemu-system-ppc''. Symbolic links from the old binary are preserved to simplify the transition.
* In-tree builds are not supported anymore. The build system will try to cater for ''./configure && make && make install'' by building QEMU in a directory named ''build'', but you are encouraged to switch to out-of-tree builds instead.
* ivshmem-client and ivshmem-server are not installed anymore. They are merely examples, and not to be used in production.
* QEMU installations are now relocatable. For example, if QEMU is configured with ''bindir=/usr/local/bin'' and ''datadir=/usr/local/share'', when QEMU is launched as ''/opt/local/qemu-5.2/bin/qemu-system-x86_64'' it will look automatically for data files in ''/opt/local/qemu-5.2/share''. Note that directories configured outside the prefix (as is often the case for ''/etc'' and ''/var'') will not be relocated! Previously this was done only under Windows and only for emulators.
=== Python ===
* Python 3.6 or newer is now required to build QEMU.
=== GIT submodules ===
=== Container Based Builds ===
* All Debian 9 based cross-compiler containers have been updated to Debian 10
=== Build Dependencies ===
* Ninja 1.7 or newer is now required to build QEMU:
* '''$ apt-get install ninja-build''' (Debian/Ubuntu and derivative distros)
* '''$ dnf/yum install ninja-build''' (RHEL/Fedora/CentOS and derivative distros)
* '''$ brew install ninja''' (macOS with HomeBrew)
* '''$ pkg install ninja''' (FreeBSD)
=== Windows ===
* qemu-nbd is now built on mingw, and works for simple cases even if it can't duplicate the full functionality available on Unix systems
=== Testing and CI ===
* a new script can wait on gitlab to finish with a pass/fail status (scripts/ci/gitlab-status)

@Update to 4.0.0
Changelog:
Incompatible changes
The "handle" option to -fsdev and -virtfs has been removed. The "local" or "proxy" options should be used instead.
The "-virtioconsole" option has been removed. Use "-device virtconsole" instead.
The "-no-frame" option has been removed. It was only usable with SDL1.2, and support for this library has been suspended now.
The "-enable-hax" option has been removed. Use "-accel hax" instead.
The "-clock" option has been removed. It was only a "dummy" option without meaning since QEMU 1.7, so there is no replacement.
The legacy "ivshmem" device has been removed. Use "ivshmem-doorbell" or "ivshmem-plain" instead.
The x86 machine types "pc-0.10" and "pc-0.11" have been removed. Use a newer machine type instead.
The "irq" property of the "spapr-vscsi", "spapr-vlan" and "spapr-vty" devices has been removed with no replacement.
The "memory-backend-memfd" backend object type will be reported as unavailable on hosts systems without memfd sealing support. On previous versions, "memory-backend-memfd" was reported as available, but didn't work properly without sealing support.
HMP snapshot commands (such as "savevm", "loadvm" and "delvm") use only the snapshot tag, and not the ID any more, to identify snapshots. This removes ambiguity from the interface, but may require changing the HMP command in existing scripts.
New deprecated options and features
cpu-add QMP/HMP command
machine-types pc-0.12, pc-0.13, pc-0.14 and pc-0.15
qemu-nbd --partition=N option
The query-events QMP command has been superseded by the more powerful and accurate query-qmp-schema command.
The acl option to the "-vnc" argument has been replaced by the tls-authz and sasl-authz options.
The acl_show, acl_reset, acl_policy, acl_add, and acl_remove commands are deprecated with no replacement. Authorization for VNC should be performed using the pluggable QAuthZ objects.
QEMU_AUDIO_ environment variables and "-audio-help" are now deprecated. Use "-audiodev" instead.
Consult the "Deprecated Features" appendix for the full list of historically deprecated features/options.
Architercture specific summary:
Arm
Implement the ARMv8.0-SB extension
Implement the ARMv8.0-PredInv extension
Implement the ARMv8.1-HPD extension
Implement the ARMv8.1-LOR extension (as the trivial "no limited ordering regions provided" minimum)
Implement the ARMv8.2-FHM extension
Implement the ARMv8.2-AA32HPD extension
Implement the ARMv8.3-PAuth extension
Implement the ARMv8.3-JSConv extension
Implement the ARMv8.4-CondM extension
Implement the ARMv8.5-CondM extension
Implement the ARMv8.5-FRINT extension
And new boards
MIPS
Added support for I7200 CPU (nanoMIPS32 ISA + DSP ASE; system mode only).
Added support for I6500 CPU (MIPS64R6 ISA + MSA ASE + multicore features).
Added support for QMP-based querying of the available CPU types.
Added support for SAARI and SAAR configuration registers.
Added support for MTTCG (multi-threaded TCG).
Improved support for ITU (Interthread Communication Unit).
Improved support for Fulong 2E machine.
Improved end user documentation.
Fixed build for MIPS n32 hosts.
RISC-V
The virt board now supports PCI and USB.
The FS field of mstatus now supports three states (dirty, clean, and off).
The TSR, TW, and TVM fields of mstatus are now implemented.
The misa CSR is now writable.
The built-in gdbserver supports register lists via XML files.
The sifive_u machine supports SMP.
The SiFive UART supports TX interrupts.
The sifive_u machine has the correct number of PLIC interrupts.
x86
The HAX accelerator is now supported for POSIX hosts other than Darwin, including Linux and NetBSD.
Machines pc-* now support configuring firmware with -machine pflash0=ID0,pflash1=ID1 in addition to -drive if=pflash,... This permits use of -blockdev.
MPX is considered a failed experiment by Intel, and has thus been removed from all named CPU models. It is still accessible via "-cpu host".
PVH Linux images can be booted with "-kernel".
