As a wonderful gift to open-source Linux virtualization users this Christmas Eve is the release of the QEMU 10.2 emulator.
QEMU 10.2 brings a number of new features and changes including:
- On systems supporting IO_uring, QEMU's main loop is now based on IO_uring to improve performance and enable other new featues and potential future performance improvements.
- Replay Protected Memory Block "RPMB" emulation to the eMMC device model is added.
- Removal of the deprecated VFIO platform, VFIO Calxeda XGMAC, and VFIO AMD XGBE drivers.
- The 9pfs file-system code now supports FreeBSD hosts.
- QEMU sanity check improvements to the crypto subsystem code.
- Dropping support for the old Arm PXA CPU family.
- Various user-mode emulation improvements.
- The minimum supported Rust version is bumped to 1.83.
