Hi, Starting on Linux 6.6 the QEMU RISC-V KVM driver now supports KMV_GET_REG_LIST. This API will make it simpler for the QEMU KVM driver to determine whether a KVM reg is present or not.
We'll use this API to fetch ISA_EXT regs during init(). The current logic will be put in a legacy() helper and will still be used in case the host KVM module does not support get-reg-list. Patch 1 contains error handling changes in kvm_riscv_init_multiext_cfg() where we're using &error_fatal and errno.
