Alpha

Arm

  • QEMU now supports emulation of the Arm-v8.1M architecture and the Cortex-M55 CPU
  • xlnx-zynqmp boards now support the Xilinx ZynqMP CAN controllers
  • the sbsa-ref board now supports Cortex-A53/57/72 cpus
  • the xlnx-versal board now has USB support
  • the sabrelite board emulation has been improved and it can now run U-Boot

AVR

HPPA

Microblaze

MIPS

  • Loongson-3 "virt" machine added

Nios2

OpenRISC

PowerPC

  • Deprecated 'compat' property of server class POWER cpus removed (use the 'max-cpu-compat' machine option instead)
  • You can now explicitly choose 'kvm_type=auto' rather than only being able to do that by not setting it at all.

Renesas RX

Renesas SH

RISC-V

  • Improve the sifive_u DTB generation
  • Add QSPI NOR flash to Microchip PFSoC
  • Fix a bug in the Hypervisor HLVX/HLV/HSV instructions
  • Fix some mstatus mask defines
  • Ibex PLIC improvements
  • OpenTitan memory layout update (Breaking change)
  • Initial steps towards support for 32-bit CPUs on 64-bit builds

s390

SPARC

TileGX

Tricore

x86

  • Intel PT can now be exposed to KVM guests when CPUID.(EAX=14,ECX=0).ECX[LIP] (bit 31) is 1. Previous versions only supported Intel PT when LIP=0
  • New sev-inject-launch-secret QMP command
  • The WHPX accelerator supports accelerated APIC ("-accel whpx,kernel-irqchip=on")

Migration

Monitor

QMP

  • A new command set-action has been introduced. The command generalizes watchdog-set-action and allows changes to all the settings of the (also new) -action command line option.

HMP

Network

Block device backends and tools

Tracing

Miscellaneous

  • A new command line option -action, with suboptions panic, shutdown, reboot and watchdog. -action subsumes the pre-existing options -no-shutdown (-action panic=pause,shutdown=pause), -no-reboot (-action reboot=shutdown) and -watchdog-action; plus, it allows the user to choose whether guest panic should pause the guest (-action panic=pause), shut it down (-action panic=poweroff, the default) or be ignored (-action panic=none).
