[PATCH v16 00/17] KVM RISC-V Support

2021-01-15 Thread Anup Patel
This series adds initial KVM RISC-V support. Currently, we are able to boot Linux on RV64/RV32 Guest with multiple VCPUs. Key aspects of KVM RISC-V added by this series are: 1. No RISC-V specific KVM IOCTL 2. Minimal possible KVM world-switch which touches only GPRs and few CSRs 3. Both RV64 and R
