Hi Paolo, We have the following KVM RISC-V changes for 6.8: 1) KVM_GET_REG_LIST improvement for vector registers 2) Generate ISA extension reg_list using macros in get-reg-list selftest 3) Steal time account support along with selftest Please pull. Please note that I will be sending another PR for 6.8 which will include two more changes: 1) KVM RISC-V report more ISA extensions through ONE_REG 2) RISC-V SBI v2.0 PMU improvements and Perf sampling in KVM guest Two separate PRs are because #1 (above) depends on a series merged by Palmer for 6.8 and #2 (above) requires little more testing. I hope you are okay with two separate PRs for 6.8.
