This series extends KVM RISC-V to allow Guest/VM discover and use conditional operations related ISA extensions (namely XVentanaCondOps and Zicond). To try these patches, use KVMTOOL from riscv_zbx_zicntr_smstateen_condops_v1 branch at: https://github.com/avpatel/kvmtool.git These patches are based upon the latest riscv_kvm_queue and can also be found in the riscv_kvm_condops_v2 branch at: https://github.com/avpatel/linux.git Changes since v1: - Rebased the series on riscv_kvm_queue - Split PATCH1 and PATCH2 of v1 series into two patches - Added separate test configs for XVentanaCondOps and Zicond in PATCH7 of v1 series.
