QEMU 9.2 Brings AWS Nitro Enclave Emulation, Many RISC-V Improvements
Coming three months after QEMU 9.1, the QEMU 9.2 release is here to introduce a new “nitro-enclave” machine type for emulating an AWS Nitro Enclave environment and boot from an EIF (Enclave Image Format) file, and to implement a single entry floating-point exception queue for SPARC v7/v8 architectures.
QEMU 9.2 also brings numerous RISC-V improvements like support for control flow integrity extensions, support for the IOMMU with the virt machine, Svvptc extension support, preliminary textra trigger CSR functions, a property to set vl to ceil(AVL/2), and a ‘fcsr’ register to the QEMU log as a part of the F extension.

QEMU 9.2 Released with Enhanced RISC-V Support and New Machine Types
QEMU, the popular open-source machine emulator and virtualizer, has just introduced its 9.2 release, bringing a range of noteworthy enhancements, deprecations, and removals.
Although this update includes several breaking changes, it also offers a clearer roadmap and improved support for emerging hardware features and configurations. In other words, while QEMU 9.2 might require users to adjust some of their existing setups, it ultimately aims to pave the way for a more flexible and future-proof virtualization environment.
To start with, QEMU 9.2 removes several long-deprecated features and options. For instance, the -rotate and -portrait command-line options, previously associated with PXA2xx machines, have been dropped since those machines are no longer supported.
