About this tag
The RISC-V KVM tag covers discussions about the KVM (Kernel-based Virtual Machine) hypervisor implementation for the RISC-V architecture on WindowsForum.com. Content includes technical details such as a fix for a VMID detection routine that violated the RISC-V Privileged Architecture specification by writing non-zero fields into the hgatp CSR when MODE was BARE, tracked as CVE-2025-40065. This tag is relevant for developers and IT professionals working with RISC-V virtualization, kernel patches, and hypervisor compliance. Topics focus on upstream kernel fixes, specification adherence, and low-level CSR handling in RISC-V KVM.

    RISC-V KVM VMID Fix: Correct HGATP Write for Bare MODE Compliance

    A subtle specification mismatch in the RISC‑V KVM code has been fixed upstream: the kernel’s VMID detection routine wrote non‑zero fields into the hgatp CSR while probing for supported VMID bits, violating the RISC‑V Privileged Architecture requirement that when MODE = BARE the remaining fields...
