It's defined in util/util.c and gets set from the begining of perf run. No need to duplicate it. Signed-off-by:

They're never used and looks like leftovers from the porting of trace-cmd code. Signed-off-by:

It's not set from anywhere so no need to keep it. Looks like an unneeded copy of the same variable in trace-event-read.c Signed-off-by:

The disasm_line__calc_percent() which was used by annotate browser code almost duplicates disasm__calc_percent. Let's get rid of the code duplication. Signed-off-by:

Make percent field of struct browser_disasm_line an array and move it to the last. This is a preparation of event group view feature. Signed-off-by:

Dynamically allocate source_line_percent according to a number of group members and save nr_pcnt to the struct source_line. This way we can handle multiple events in a general manner. However since the size of struct source_line is not fixed anymore, iterating whole source_line should care about its size. $ perf annotate --group --stdio --print-line Sorted summary for file /lib/ld-2.11.1.so ---------------------------------------------- 33.33 0.00 /build/buildd/eglibc-2.11.1/elf/rtld.c:381 33.33 0.00 /build/buildd/eglibc-2.11.1/elf/dynamic-link.h:128 33.33 0.00 /build/buildd/eglibc-2.11.1/elf/do-rel.h:105 0.00 75.00 /build/buildd/eglibc-2.11.1/elf/dynamic-link.h:137 0.00 25.00 /build/buildd/eglibc-2.11.1/elf/dynamic-link.h:187 ...

The perf_evsel__is_group_event function is for checking whether given evsel needs event group view support or not. Please note that it's different to the existing perf_evsel__is_group_leader() which checks only the given evsel is a leader or a standalone (i.e. non-group) event regardless of event group feature.

Add --group option to enable event grouping. When enabled, all the group members information will be shown with the leader so skip non-leader events. It only supports --stdio output currently. Later patches will extend additional features. $ perf annotate --group --stdio ...

The loop end condition is calculated from next disasm_line or the symbol size if it's the last disasm_line. But it doesn't need to be calculated at every iteration. Moving it out of the function can simplify code a bit. Also the src_line doesn't need to be checked in every time. Signed-off-by:

Since it's only used for checking ->pipe_output, we can pass the result directly. Now the perf_evlist__prepare_workload() don't have a dependency of struct perf_record_opts, it can be called from other places like perf stat. Signed-off-by:

Jiri Olsa triggers the following build error: SUBDIR ../lib/lk/ CC debugfs.o In file included from /usr/include/errno.h:29:0, from debugfs.c:1: /usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp] This is because enabling buffer overflow checks through _FORTIFY_SOURCE require compiler optimizations to be enabled too. However, those are not. Enable them by simply copying the perf optimization level. It can be expanded later if we want to support debug builds, etc. Signed-off-by:Borislav Petkov <bp@suse.de> Reported-by:

It looks at O= and adjusts the $(OUTPUT) variable based on what the output directory will be. However, when O is defined but empty, it wrongly becomes the user's $HOME dir which is not what we want. So check it is not empty before working with it further. Signed-off-by:
