We define two macros for the above purpose: 1) KVM_ISA_EXT_SIMPLE_CONFIG - Macro to generate reg_list for ISA extension without any additional ONE_REG registers 2) KVM_ISA_EXT_SUBLIST_CONFIG - Macro to generate reg_list for ISA extension with additional ONE_REG registers Signed-off-by: Anup Patel Reviewed-by: Andrew Jones --- .../selftests/kvm/riscv/get-reg-list.c | 331 ++++-------------- 1 file changed, 76 insertions(+), 255 deletions(-) diff --git a/tools/testing/selftests/kvm/riscv/get-reg-list.c b/tools/testing/selftests/kvm/riscv/get-reg-list.c index 6bedaea95395..b6b4b6d7dacd 100644 --- a/tools/testing/selftests/kvm/riscv/get-reg-list.c +++ b/tools/testing/selftests/kvm/riscv/get-reg-list.c @@ -581,10 +581,6 @@ static __u64 base_skips_set[] = { KVM_REG_RISCV | KVM_REG_SIZE_U64 | KVM_REG_RISCV_TIMER | KVM_REG_RISCV_TIMER_REG(state), };
