Subject[PATCH 0/4] RISCV: Add kvm Sstc timer selftest
Date
The sstc_timer selftest is used to validate Sstc timer functionality
in a guest, which sets up periodic timer interrupts and check the
basic interrupt status upon its receipt.

This KVM selftest was ported from aarch64 arch_timer and tested
with Linux v6.5-rc3 on a Qemu riscv64 virt machine.

Haibo Xu (4):
tools: riscv: Add header file csr.h
KVM: riscv: selftests: Add exception handling support
KVM: riscv: selftests: Add guest helper to get vcpu id
KVM: riscv: selftests: Add sstc_timer test
