Subject: [PATCH v3] perf vendor events: Add metrics for Icelake Server

Add JSON metrics for Icelake Server to perf.

Based on TMA metrics 4.21 at 01.org.
https://download.01.org/perfmon/

Signed-off-by: Jin Yao <[email protected]>
---
v3:
- PMU cstate_core and cstate_pkg are supported for ICX since 5.14-rc1,
add cstate metrics for Core C1/C6 and Package C2/C6.

v2:
- Fix perf test 10 error.

# ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

- Remove cstate metrics because the kernel has not supported
cstate_core and cstate_core for Icelake server.

- Remove the topdown L1/L2 metrics.

Subject: Re: [PATCH v3] perf vendor events: Add metrics for Icelake Server

Hi Andi,

I guess Arnaldo needs your ACK before consider picking up this patch.

Can you give an ACK for this patch?

Thanks

Hi,

I'm not sure what's happening but when I generate this using:
https://github.com/intel/event-converter-for-linux-perf

I see here:
"MetricExpr": "1 / IPC",

There are various other differences and so I've included the generated file.

Thanks,
Ian

Please see following commit in event-converter-for-linux-perf repo.

commit b2265b953d57130a2ad8255d126bb69cf8552898
Author: Jin Yao <[email protected]>
Date: Thu Jun 3 09:57:01 2021 +0800

Don't expand inner metric if possible

Before:

{
"MetricExpr": "1 / (INST_RETIRED.ANY / CPU_CLK_UNHALTED.THREAD)",
"BriefDescription": "Cycles Per Instruction (per Logical Processor)",
"MetricGroup": "Pipeline",
"MetricName": "CPI"
},

After:

{
"MetricExpr": "1 / IPC",
"BriefDescription": "Cycles Per Instruction (per Logical Processor)",
"MetricGroup": "Pipeline",
"MetricName": "CPI"
},

We also provide a new option '--expr-events' for checking if it's a complex
metric. For a simple metric, we probablly don't need to reuse the inner
metric. For a complex metric, it's useful to reuse the inner metric.

I enable the option '--expr-events' when generating the metrics JSON. Since CPI is a simple metric,
so the inner metric is still expanded.

For cstate metrics, only Core C1/C6 and Package C2/C6 are supported for ICX. The cstate metrics are
appended manually right now.

Thanks
