CTOnews.com August 24, the open source QEMU 8.1 device emulator and virtualization software have been officially released, this is the first major update of the QEMU 8.0 series, friends can find the relevant download address here.

▲ source QEMU official website QEMU (Quick Emulator) is one of the mainstream device simulation software in the industry, which can run operating systems and programs supporting other architectures on physical machines with one architecture (such as X86 PC), so that the software can run under different hardware architectures without awareness. For software developers, QEMU can provide a platform for system execution under different hardware architectures, as well as a software cross-architecture integrated test environment to improve software development efficiency and maturity.

The main update log of QEMU 8.1 attached to CTOnews.com is as follows:

New x86 CPU model supporting Intel Granite Rapids

The microcode generator (Tiny Code Generator, TCG) supports RDPID instructions, AES instructions can use AES acceleration on the host processor, and other new features

From supporting BF16 extensions to Zfa extensions, Zcm* extensions and other RISC-V architecture improvements, Ventana Veyron V1 CPU and many RISC-V fixes have also been added

Support for LoongArch LSX extensions and various fixes for the CPU architecture
