Subject: [PATCH v2 0/8] RISCV: Add kvm Sstc timer selftest
The RISC-V arch_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-rc5 on a Qemu riscv64 virt machine.
---
Changed since v1:
* Rebase to kvm-riscv/riscv_kvm_next
* Cherry-pick Sean's kselftest guest printf patch set
https://lore.kernel.org/all/20230729003643.1053367-1-seanjc@google.com/
* Copy the entire csr.h verbatim
* Unified the function names for exception vector table setup
void vm_init_vector_tables(struct kvm_vm *vm);
void vcpu_init_vector_tables(struct kvm_vcpu *vcpu);
* Format the handler.S asm file per Andrew's comments
* Consolidate the timer test code for arm64 and riscv
based on Andrew's and Sean's suggestion
