tools perf: Add arm64 sysreg files to MANIFEST

2023-11-22T19:17:53+00:00

Ian pointed out that source tarballs are incomplete as of commit
e2bdd172e665 ("perf build: Generate arm64's sysreg-defs.h and add to
include path"), since the source files needed from the kernel tree do
not appear in the manifest. Add them.

tools lib traceevent: Remove libtraceevent

2022-12-14T14:16:12+00:00

libtraceevent is now out-of-date and it is better to depend on the
system version. Remove this code that is no longer depended upon by
any builds.

Committer notes:

Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so
that 'make perf-tar-src-pkg' works.

perf build: Install libsymbol locally when building

2022-11-16T15:17:15+00:00

The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf and libsymbol headers are all found via this path, making it
impossible to override include behavior.

Change the libsymbol build mirroring the libbpf, libsubcmd, libapi,
libperf and libtraceevent build, so that it is installed in a directory
along with its headers.

A later change will modify the include behavior.  Don't build kallsyms.o
as part of util as this will lead to duplicate definitions. Add
kallsym's directory to the MANIFEST rather than individual files, so
that the Build and Makefile are added to a source tar ball.

perf MANIFEST: Add bpftool files to allow building with BUILD_BPF_SKEL=1

2021-11-07T18:39:28+00:00

We need bpftool and required kernel/bpf/disasm.[ch] to bootstrap the
cgroups, bperf and other BPF skels used by perf.

tools lib: Adopt list_sort() from the kernel sources

2021-10-20T13:30:59+00:00

Add list_sort.[ch] from the main kernel tree. The linux/bug.h #include
is removed due to conflicting definitions. Add check-headers and modify
perf build accordingly.

MANIFEST and python-ext-sources fixes suggested by Arnaldo.

scripts/bpf: Abstract eBPF API target parameter

2021-03-05T02:39:45+00:00

Abstract out the target parameter so that upcoming commits, more than
just the existing "helpers" target can be called to generate specific
portions of docs from the eBPF UAPI headers.

libperf: Move to tools/lib/perf

2020-01-06T14:46:09+00:00

Move libperf from its current location under tools/perf to a separate
directory under tools/lib/.

Also change various paths (mainly includes) to reflect the libperf move
to a separate directory and add a new directory under MANIFEST.

libbpf: Fix up generation of bpf_helper_defs.h

2019-11-28T00:52:31+00:00

  $ make -C tools/perf build-test

does, ends up with these two problems:

  make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'.  Stop.
  make[3]: *** Waiting for unfinished jobs....
  make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2
  make[2]: *** Waiting for unfinished jobs....

Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory
and we need '/tools/ after that variable, and after fixing this then we
get to another problem:

  /bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory
  make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127
  make[3]: *** Deleting file 'bpf_helper_defs.h'
    LD       /tmp/build/perf/libapi-in.o
  make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2
  make[2]: *** Waiting for unfinished jobs....

Because this requires something outside the tools/ directories that gets
collected into perf's detached tarballs, to fix it just add it to
tools/perf/MANIFEST, which this patch does, now it works for that case
and also for all these other cases.

tools lib: Move argv_{split,free} from tools/perf/util/

2019-07-02T01:50:40+00:00

This came from the kernel lib/argv_split.c, so move it to
tools/lib/argv_split.c, to get it closer to the kernel structure.

We need to audit the usage of argv_split() to figure out if it is really
necessary to do have one allocation per argv[] entry, looking at one of
its users I guess that is not the case and we probably are even leaking
those allocations by not using argv_free() judiciously, for later.

With this we further remove stuff from tools/perf/util/, reducing the
perf specific codebase and encouraging other tools/ code to use these
routines so as to keep the style and constructs used with the kernel.
