Hi Paolo,
We have the following KVM RISC-V changes for 6.1:
1) Improved instruction encoding infrastructure for
instructions not yet supported by binutils
2) Svinval support for both KVM Host and KVM Guest
3) Zihintpause support for KVM Guest
4) Zicbom support for KVM Guest
5) Record number of signal exits as a VCPU stat
6) Use generic guest entry infrastructure
Please pull.
Regards,
Anup
