Subject: [PATCH v3 0/7] perf/probe: Support multiprobe and immediates with fixes
Date: Mon, 18 Nov 2019 17:11:40 +0900	[thread overview]
Message-ID: <157406469983.24476.13195800716161845227.stgit@devnote2> (raw)

Hi Arnaldo,

This is the 3rd version of the multiprobe support on perf probe
including some fixes about "representive lines"

The previous thread is here:

https://lkml.kernel.org/r/157314406866.4063.16995747442215702109.stgit@devnote2

On the previous thread, we discussed some issues about incorrect line
information shown by perf probe. I finally fixed those by introducing
an idea of "representive line" -- a line which has a unique address
(no other lines shares the same address) or a line which has the least
line number among lines sharing same address. Now perf probe only shows
such representive lines can be probed([1/7][3/7]), and if user tries to
probe other non representive lines, it shows which line user should
probe ([2/7]). The rest of patches in the series are same as v2 (except
for [4/7], example output is updated)

This can be applied on top of perf/core.

Thank you,
