Hi Paolo,
We have the following KVM RISC-V changes for 6.16:
1) Add vector registers to get-reg-list selftest
2) VCPU reset related improvements
3) Remove scounteren initialization from VCPU reset
4) Support VCPU reset from userspace using set_mpstate() ioctl
(NOTE: we have re-used KVM_MP_STATE_INIT_RECEIVED
for this purpose since it is a temporary state. This way of
VCPU reset only resets the register state and does not
affect the actual VCPU MP_STATE. This new mechanism
of VCPU reset can be used by KVM user space upon
SBI system reset to reset the register state of the VCPU
initiating SBI system reset. )
Please pull.
Regards,
Anup
