Hi Paolo, We have the following KVM RISC-V changes for 6.13: 1) Accelerate KVM RISC-V when running as a guest 2) Perf support to collect KVM guest statistics from host side In addition, the pointer masking support (Ssnpm and Smnpm) for KVM guest is going through the RISC-V tree. I also have Svade and Svadu support for host and guest in my queue which I will send in the second week of the merge window to avoid conflict with the RISC-V tree. Please pull.
Pulled, thanks. Paolo
