A VirtIO-GPU device that provides virtual GPU functionality has been added supporting 3D acceleration using the Vulkan graphics API, implemented through the Mesa Vulkan driver Venus, which allows the guest system to use a virtual GPU for 3D rendering without granting exclusive direct access to the physical GPU. To function, the virglrenderer library must be present on the host system and the Mesa driver Venus on the guest system. Instructions for setting up Vulkan support in QEMU are available.\n
The guest migration toolkit has added support for accelerating compression operations of concurrently transmitted data streams using the QATzip library, which employs Intel's built-in QAT (QuickAssist Technology) accelerator, offering tools for accelerating computations related to compression and encryption.\n
Support for the SHA-384 hashing algorithm has been added to the cryptographic backend based on GLib.\n
The ARM architecture emulator has added support for the FEAT_EBF16 and FEAT_CMOW processor extensions, as well as security extensions used in xilinx-zynq-a9 boards. When using the HVF component, which leverages the Hypervisor.framework toolkit to accelerate guest system execution on ARM Mac computers, support for more than 64 GB of memory has been enabled. Support for two-stage address translation in SMMU (System Memory Management Unit) has been added for emulated systems sbsa-ref and virt. Support for outdated emulated hardware types akita, borzoi, cheetah, connex, mainstone, n800, n810, spitz, terrier, tosa, verdex, and z2 has been discontinued.\n
