Subject: [PATCH v4 00/11] RISCV: Add kvm Sstc timer selftests
Date:   Tue, 12 Dec 2023 17:31:09 +0800
Message-Id: <cover.1702371136.git.haibo1.xu@intel.com>

Precedence: bulk

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 v6.7-rc4 on a Qemu riscv64 virt machine.

---
Changed since v4:
  * Rebased to Linux 6.7-rc4
  * Included Paolo's patch(01/11) to fix issues with SPLIT_TESTS
  * Droped the patch(KVM: selftests: Unify the makefile rule for split targets) 
    since Paolo's patch had included the fix
  * Added new patch(05/11) to include header file vdso/processor.h from linux
    source tree to leverage the cpu_relax() definition - Conor/Andrew
  * Added new patch(11/11) to enable user configuration of timer error margin
    parameter which alleviate the intermitent failure in stress test - Andrew
  * Other minor fixes per Andrew's comments
