From: Mingwang Li limingwang@huawei.com
euleros inclusion category: feature feature: initial KVM RISC-V support bugzilla: 46845 CVE: NA
This series adds initial KVM RISC-V support. Currently, we are able to boot Linux on RV64/RV32 Guest with multiple VCPUs.
This series can be found in riscv_kvm_v15 branch at: https//github.com/avpatel/linux.git
Changes since v1
- follow guileline for submiting patches to openEuler
- add the testing result in this issue
