2023-08-03perf tests task_analyzer: Check perf build options for libtraceevent supportAditya Gupta
Currently we depend on output of 'perf record -e "sched:sched_switch"', to check whether perf was built with libtraceevent support. Instead, a more straightforward approach can be to check the build options, using 'perf version --build-options', to check for libtraceevent support. When perf is compiled WITHOUT libtraceevent ('make NO_LIBTRACEEVENT=1'), 'perf version --build-options' outputs (output trimmed): ... libtraceevent: [ OFF ] # HAVE_LIBTRACEEVENT ... While, when perf is compiled WITH libtraceevent, 'perf version --build-options' outputs: ... libtraceevent: [ on ] # HAVE_LIBTRACEEVENT ... Committer notes: Removed one grep in the pipleline by combining the two into just one expression that covers the OFF + HAVE_LIBTRACEEVENT.

2023-08-03perf tools: Revert enable indices setting syntax for BPF mapIan Rogers
This reverts commit e571e029bdbf ("perf tools: Enable indices setting syntax for BPF map"). The reverted commit added a notion of arrays that could be set as event terms for BPF events. The parsing hasn't worked over multiple Linux releases. Given the broken nature of the parsing it appears the code isn't in use, nor could I find a way for it to be used to add a test. The original commit contains a test in the commit message, however, running it yields: ``` $ perf record -e './test_bpf_map_3.c/map:channel.value[0,1,2,3...5]=101/' usleep 2 event syntax error: '..pf_map_3.c/map:channel.value[0,1,2,3...5]=101/' \___ parser error Run 'perf list' for a list of valid events Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -e, --event <event> event selector. use 'perf list' to list available events ``` Given the code can't be used this commit reverts and removes it.

2023-08-03perf build: Include generated header files properlyNamhyung Kim
The flex and bison generate header files from the source. When user specified a build directory with O= option, it'd generate files under the directory.

2023-08-03perf build: Update build rule for generated filesNamhyung Kim
The bison and flex generate C files from the source (.y and .l) files. When O= option is used, they are saved in a separate directory but the default build rule assumes the .C files are in the source directory. So it might read invalid file if there are generated files from an old version. The same is true for the pmu-events files. For example, the following command would cause a build failure: $ git checkout v6.3 $ make -C tools/perf # build in the same directory $ git checkout v6.5-rc2 $ mkdir build # create a build directory $ make -C tools/perf O=build # build in a different directory but it # refers files in the source directory Let's update the build rule to specify those cases explicitly to depend on the files in the output directory. Note that it's not a complete fix and it needs the next patch for the include path too.
