[QEMU 11.0] Brings New RISC-V Extensions, Fixes

QEMU 11.0 Brings New RISC-V Extensions, Fixes The latest release of the QEMU emulator, version 11.0, is out, and brings with it support for the RISC-V Zilsd, Zclsd, Zalasr, and Smpmpmt extensions - plus various compatibility and security fixes. “We’d like to announce the availability of the QEMU 11.0.0 release. This release contains 2500+ commits from 237 authors,” the project maintainers write of the new release. “Thank you to everybody who contributed to this release, whether that was by writing code, reporting bugs, improving documentation, testing, or providing the project with CI resources. We couldn’t do these without you!” The latest QEMU release brings with it support for four new extensions to the free and open RISC-V instruction set architecture: Zilsd and Zclsd, RV32-exclusive extensions to add register pair load and store instructions by reusing existing RV64-only instruction encodings; Zalasr, an atomic load-acquire store-release extension; and Smpmpmt, which provides a memory attribute control mechanism analogous to the RV64-only Rvpmt using PMP registers. The full changelog is available on the QEMU wiki; releases are available on the project website, with full source code available on GitLab under the reciprocal GNU General Public Licence 2 or later.
