[PATCH v6 0/3] perf vendor events: Support PMU events for A64FX

From: Shunsuke Nakamura <hidden>
Date: 2021-02-12 09:12:41

This patch series supports A64FX PMU event v1.2.

The first patch add more common and microarchitecture events.
This patch is based on john's patch [1].

The second patch fixes the lexical definition of event name so that
perf can recognize event name that start with a number.

The third patch adds PMU events for A64FX.


Changes in v5:
 - Removed john's patch [1] from this patch series.
 - Added the missing Reviewed-by tag to the patch.
 - Fixed the base of the patch series.[2]
 - Changed subject from fix to added.

Changes in v4:
 - Add arm64 to the subjects of the second and fourth patches.
 - Add reference URLs to the body of the second patch.

Changes in v3:
 - Add linux-arm-kernel mailing list to cc.

Changes in v2:
 - Added armv8-common-and-microarch based on John's patch.[1]
 - Fixed A64FX Json to refer to standard events in armv8-common-and-microarch.

[PATCH v6 2/3] perf tools: Add lexical definition of event name

From: Shunsuke Nakamura <hidden>
Date: 2021-02-12 09:12:41

Add the lexical definition of event name so that the numbers are recognizable.

A64FX defines an event name that starts with a number.

I can't see anything broken because of this change,
also numbers are defined few lines before so we should
be fine

but please add test for this to tests/parse-events.c,
if you could also add test for 'VALUE:VALUE' event,
that'd be fantastic ;-)

thanks,

Add the lexical definition of event name so that the numbers are recognizable.

A64FX defines an event name that starts with a number.
 - 0inst_commit
 - 1inst_commit
 - 2inst_commit
 - 3inst_commit
 - 4inst_commit

be fine
But this change makes the syntax ambiguous with numbers
and names. I don't think it's a good idea.

Is it possible to change the event names not having numbers
at the beginning like inst_commit0, inst_commit1 and so on?

Thanks,
Namhyung

I'll check again, but we already have hex numbers above
which could easily clash, but the syntax context makes
this work.. tests should help to clear this up
Is it possible to change the event names not having numbers
at the beginning like inst_commit0, inst_commit1 and so on?
that'd be of course much better
