Drop -Werror in perf

2011-08-01T20:55:00+00:00

Drop -Werror in perf Makefile. This fixes the build with gcc 4.5.x Not in mainline. Signed-off-by: Andi Kleen

perf tools: Fix fallback to cplus_demangle() when bfd_demangle() is not available

2010-07-22T20:30:39+00:00

make version 3.80 doesn't support "else ifdef" on the same line, also it doesn't support unindented nested constructs. Build fails with: Makefile:608: Extraneous text after `else' directive Makefile:611: *** only one `else' per conditional. Stop. This patch fixes the build for make 3.80.

perf tools: Add mode to build without newt support

2010-05-17T21:18:11+00:00

make NO_NEWT=1 Will avoid building the newt (tui) support. Suggested-by: Ingo Molnar LKML-Reference: Signed-off-by: Arnaldo Carvalho de Melo

perf tui: Add explicit -lslang option

2010-05-17T19:42:37+00:00

At least on rawhide using -lnewt is not enough if we use SLang routines directly, so add an explicit -lslang since we use SLang routines. Reported-by: Ingo Molnar Tested-by: Ingo Molnar Signed-off-by: Arnaldo Carvalho de Melo

perf newt: Make <- zoom out filters

2010-05-14T23:05:21+00:00

After we use the filters to zoom into DSOs or threads, we can use <- (left arrow) to zoom out from the last filter applied. It is still possible to zoom out of order by using the popup menu. With this we now have the zoom out operation on the browsing fast path, by allowing fast navigation using just the four arrors and the enter key to expand collapse callchains.

perf report: Librarize the annotation code and use it in the newt browser

2010-05-12T02:23:20+00:00

Now we don't anymore use popen to run 'perf annotate' for the selected symbol, instead we collect per address samplings when processing samples in 'perf report' if we're using the newt browser, then we use this data directly to do annotation. Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.

perf symbols: allow forcing use of cplus_demangle

2010-05-11T15:43:11+00:00

For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in the buildroot.

perf probe: Check older elfutils and set NO_DWARF

2010-05-11T15:43:11+00:00

Check whether elfutils is older than 0.138 (from which version checking routine has been introduced). And if so, set NO_DWARF because it is hard to check the API dependency without version checking.

perf: add perf-inject builtin

2010-05-02T16:36:56+00:00

Currently, perf 'live mode' writes build-ids at the end of the session, which isn't actually useful for processing live mode events. What would be better would be to have the build-ids sent before any of the samples that reference them, which can be done by processing the event stream and retrieving the build-ids on the first hit. Doing that in perf-record itself, however, is off-limits. This patch introduces perf-inject, which does the same job while leaving perf-record untouched. Normal mode perf still records the build-ids at the end of the session as it should, but for live mode, perf-inject can be injected in between the record and report steps e.g.: perf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i - perf-inject reads a perf-record event stream and repipes it to stdout. At any point the processing code can inject other events into the event stream - in this case build-ids (-b option) are read and injected as needed into the event stream. Build-ids are just the first user of perf-inject - potentially anything that needs userspace processing to augment the trace stream with additional information could make use of this facility.

perf tools: Don't use code surrounded by KERNEL

2010-05-02T15:00:44+00:00

We need to refactor code to be explicitely shared by the kernel and at least the tools/ userspace programs, so, till we do that, copy the bare minimum bitmap/bitops code needed by tools/perf.
