Hello, On behalf of the QEMU Team, I'd like to announce the availability of the QEMU 4.1.0 release. This release contains 2000+ commits from 176 authors.
You can grab the tarball from our download page here: https://www.qemu.org/download/#source The full list of changes are available at: https://wiki.qemu.org/ChangeLog/4.1 Highlights include: * ARM: FPU emulation support for Cortex-M CPUs, FPU fixes for Cortex-R5F * ARM: ARMv8.5-RNG extension support for CPU-generated random numbers * ARM: board build options now configurable via new Kconfig-based system * ARM: Exynos4210 SoC model now supports PL330 DMA controllers * MIPS: improved emulation performance of numerous MSA instructions, mostly integer and data permuting operations * MIPS: improved support for MSA ASE instructions on big-endian hosts, handling for 'division by zero' cases now matches reference hardware * PowerPC: pseries: support for NVIDIA V100 GPU/NVLink2 passthrough via VFIO * PowerPC: pseries: in-kernel acceleration for XIVE interrupt controller * PowerPC: pseries: supporting for hot-plugging PCI host bridges * PowerPC: emulation optimizations for vector (Altivec/VSX) instructions * RISC-V: support for new "spike" machine model * RISC-V: ISA 1.11.0 support for privileged architectures * RISC-V: improvements for 32-bit syscall ABI, illegal instruction handling, and built-in debugger * RISC-V: support for CPU topology in device trees * s390: bios support for booting from ECKD DASD assigned to guest via vfio-ccw * s390: emulation support for all "Vector Facility" instructions * s390: additional facilities and support for gen15 machines, including support for AP Queue Interruption Facility for using interrupts for vfio-ap devices * SPARC: sun4m: sun4u: fixes when running with -vga none (OpenBIOS) * x86: emulation support for new Hygon Dhyana and Intel SnowRidge CPU models * x86: emulation support for RDRAND extension * x86: md-clear/mds-no feature flags, for detection/mitigation of MDS vulnerabilities (CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091) * x86: CPU die topology now configurable using -smp ...,dies= * Xtensa: support for memory protection unit (MPU) option * Xtensa: support for Exclusive Access option * GUI: virtio-gpu 2D/3D rendering may now be offloaded to an external vhost-user process, such as QEMU vhost-user-gpu * GUI: semihosting output can now be redirected to a chardev backend with -semihosting-config enable=on,target=native,chardev=[ID] * qemu-img: added a --salvage option to qemu-img convert, which prevents the conversion process from aborting on I/O errors (can be used for example to salvage partially corrupted qcow2 files) * qemu-img: qemu-img rebase works now even when the input file doesn't have a backing file yet * VMDK block driver now has read-only support for the seSparse subformat * GPIO: support for SiFive GPIO controller * and lots more... Thank you to everyone involved!
