[PATCH v2 0/5] perf report: Show inline stack

v2: Thanks so much for Arnaldo's comments! The modifications are: 1. Divide v1 patch "perf report: Find the inline stack for a given address" into 2 patches: a. perf report: Refactor common code in srcline.c b. perf report: Find the inline stack for a given address

[PATCH v2 1/5] perf report: Refactor common code in srcline.c

Introduce dso__name() and filename_split() out of existing code because these codes will be used in several places in next patch. For filename_split(), it may also solve a potential memory leak in existing code. In existing addr2line(), sep = strchr(filename, ':'); if (sep) {

[PATCH v2 3/5] perf report: Create a new option "--inline"

It takes some time to look for inline stack for callgraph addresses. So it provides a new option "--inline" to let user decide if enable this feature. Signed-off-by: Jin Yao --- tools/perf/Documentation/perf-report.txt | 4 tools/perf/builtin-report.c

If the address belongs to an inlined function, the source information back to the first non-inlined function will be printed. For example: 0.05% test2test2 [.] main | ---/home/jinyao/perf-dev/test/test2.c:27 (inline) /home/jinyao/perf-dev/test/test2.c:35

[PATCH v2 2/5] perf report: Find the inline stack for a given address

It would be useful for perf to support a mode to query the inline stack for a given callgraph address. This would simplify finding the right code in code that does a lot of inlining. The srcline.c has contained the code which supports to translate the address to filename:line_nr. This patch just

The SSC is currently not usable with the ASoC simple-audio-card, as every SSC audio user has to build a platform driver that may do as little as calling atmel_ssc_set_audio/atmel_ssc_put_audio (which allocates the SSC and registers a DAI with the ASoC subsystem). So, have that happen
