From 333804dc3b7a92158ab63a48febff0d8ef89ada3 Mon Sep 17 00:00:00 2001 From: Madhavan Srinivasan Date: Sun, 9 Dec 2018 14:55:35 +0530 Subject: powerpc/perf: Update perf_regs structure to include SIER On each sample, Sample Instruction Event Register (SIER) content is saved in pt_regs. SIER does not have a entry as-is in the pt_regs but instead, SIER content is saved in the "dar" register of pt_regs. Patch adds another entry to the perf_regs structure to include the "SIER" printing which internally maps to the "dar" of pt_regs. It also check for the SIER availability in the platform and present value accordingly Signed-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman --- tools/perf/arch/powerpc/include/perf_regs.h | 3 ++- tools/perf/arch/powerpc/util/perf_regs.c | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) (limited to 'tools/perf') diff --git a/tools/perf/arch/powerpc/include/perf_regs.h b/tools/perf/arch/powerpc/include/perf_regs.h index 00e37b106913..1076393e6f43 100644 --- a/tools/perf/arch/powerpc/include/perf_regs.h +++ b/tools/perf/arch/powerpc/include/perf_regs.h @@ -62,7 +62,8 @@ static const char *reg_names[] = { [PERF_REG_POWERPC_SOFTE] = "softe", [PERF_REG_POWERPC_TRAP] = "trap", [PERF_REG_POWERPC_DAR] = "dar", - [PERF_REG_POWERPC_DSISR] = "dsisr" + [PERF_REG_POWERPC_DSISR] = "dsisr", + [PERF_REG_POWERPC_SIER] = "sier" }; static inline const char *perf_reg_name(int id) diff --git a/tools/perf/arch/powerpc/util/perf_regs.c b/tools/perf/arch/powerpc/util/perf_regs.c index ec50939b0418..07fcd977d93e 100644 --- a/tools/perf/arch/powerpc/util/perf_regs.c +++ b/tools/perf/arch/powerpc/util/perf_regs.c @@ -52,6 +52,7 @@ const struct sample_reg sample_reg_masks[] = { SMPL_REG(trap, PERF_REG_POWERPC_TRAP), SMPL_REG(dar, PERF_REG_POWERPC_DAR), SMPL_REG(dsisr, PERF_REG_POWERPC_DSISR), + SMPL_REG(sier, PERF_REG_POWERPC_SIER), SMPL_REG_END }; -- cgit v1.2.3
