Subject: [PATCH v3 0/9] RISCV: Add kvm Sstc timer selftests
Date:   Thu, 14 Sep 2023 09:36:54 +0800

The RISC-V arch_timer selftests 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 selftests was ported from aarch64 arch_timer and tested
with Linux v6.6-rc1 on a Qemu riscv64 virt machine.

---
Changed since v2:
  * Rebase to Linux 6.6-rc1
  * Add separate patch for kvm/Makefile improvement
  * Move aarch64 specific macros to aarch64/arch_timer.c
  * Add -DCONFIG_64BIT to kvm/Makefile CFLAGS to ensure
    only 64bit registers were available in csr.h
  * Avoid some #ifdef in kvm/arch_timer.c by setting some
    aarch64 specific variable to 0 on risc-v
