perf tools: Pass struct perf_hpp_fmt to its callbacks

2015-01-21T16:24:34+00:00

Currently ->cmp, ->collapse and ->sort callbacks doesn't pass corresponding fmt. But it'll be needed by upcoming changes in perf diff command.

perf callchain: Make get_srcline fall back to sym+offset

2014-11-24T21:03:47+00:00

When the source line is not found fall back to sym + offset. This is generally much more useful than a raw address. For this we need to pass in the symbol from the caller. For some callers it's awkward to compute, so we stay at the old behaviour.

perf hists: Fix up srcline histogram key formatting

2014-11-19T15:33:48+00:00

Problem introduced in: commit 5b5916696051 "perf report: Honor column width setting" Where the left justification signal was after the width, which ended up, when the width was, say, 11, always printing: %11.11-s Instead of src:line left justified and limited to 11 chars. Resulting in a like: 70.93% %11.11-s [.] f2 tcall When it should instead be: 70.93% tcall.c:5 [.] f2 tcall Cc: Adrian Hunter Cc: Andi Kleen Cc: Borislav Petkov Cc: David Ahern Cc: Don Zickus Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-2xnt0vqkoox52etq2qhyetr0@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Fix report -F dso_from for data without branch info

2014-10-29T12:29:05+00:00

The branch field sorting code assumes hist_entry::branch_info is allocated, which is wrong and following perf session ends up with report segfault. $ perf record ls $ perf report -F dso_from perf: Segmentation fault Checking that hist_entry::branch_info is valid and display "N/A" string in snprint callback if it's not.
