This patch seems to have broken KVM acceleration for me: $ ./build/qemu-system-riscv64 -display none -M virt,accel=kvm -cpu host qemu-system-riscv64: Failed to put registers after init: No such file or directory Reverting it makes QEMU work again. My host is a SiFive HiFive Premier P550 board running Fedora 41. Note that, since the upstreaming effort for this SoC has just recently started, I'm using the 6.6-based vendor kernel. Perhaps the KVM UAPI additions mentioned in the commit message are more recent than that, and we need to make QEMU's use of them conditional rather than unconditional? -- Andrea Bolognani / Red Hat / Virtualization
