perf: build: Setup PKG_CONFIG_LIBDIR for cross compilation

2024-07-26T18:14:56+00:00

On recent Linux distros like Ubuntu Noble and Debian Bookworm, the
'pkg-config-aarch64-linux-gnu' package is missing. As a result, the
aarch64-linux-gnu-pkg-config command is not available, which causes
build failures.

When a build passes the environment variables PKG_CONFIG_LIBDIR or
PKG_CONFIG_PATH, like a user uses make command or a build system
(like Yocto, Buildroot, etc) prepares the variables and passes to the
Perf's Makefile, the commit keeps these variables for package
configuration. Otherwise, this commit sets the PKG_CONFIG_LIBDIR
variable to use the Multiarch libs for the cross compilation.

perf install: Don't propagate subdir to Documentation submake

2024-07-04T00:11:38+00:00

Explicitly reset 'subdir' variable when descending to
tools/perf/Documentation.  Similar to commit f89fb55714b62 ("perf build:
Don't propagate subdir to submakes for install_headers", 2023-01-02),
calling the 'tools/perf_install' target via top-levels Makefile results
in repeated subdir components when attempting to call the perf
documentation installation rules:

    $ make tools/perf_install NO_LIBTRACEEVENT=1 JOBS=1
    [...]
    /bin/sh: 1: cd: can't cd to /data/linux/kbuild/tools/perf/tools/perf/
    ../../scripts/Makefile.include:17: *** output directory "/data/linux/kbuild/tools/perf/tools/perf/" does not exist.  Stop.
    make[5]: *** [Makefile.perf:1096: try-install-man] Error 2
    make[4]: *** [Makefile.perf:264: sub-make] Error 2
    make[3]: *** [Makefile:113: install] Error 2
    make[2]: *** [Makefile:131: perf_install] Error 2

Resetting 'subdir' fixes the call from top-level Makefile.

Merge remote-tracking branch 'perf-tools' into perf-tools-next

2024-07-02T18:51:32+00:00

Merge fixes and updates in v6.10 into perf-tools-next to resolve changes
in synthesizing the LOST_SAMPLES records and build fixes.

perf python: Clean up build dependencies

2024-06-26T18:10:25+00:00

The python build now depends on libraries and doesn't use
python-ext-sources except for the util/python.c dependency. Switch to
just directly depending on that file and util/setup.py. This allows
the removal of python-ext-sources.

perf python: Switch module to linking libraries from building source

2024-06-26T18:08:00+00:00

setup.py was building most perf sources causing setup.py to mimic the
Makefile logic as well as flex/bison code to be stubbed out, due to
complexity building. By using libraries fewer functions are stubbed
out, the build is faster and the Makefile logic is reused which should
simplify updating. The libraries are passed through LDFLAGS to avoid
complexity in python.

Force the -fPIC flag for libbpf.a to ensure it is suitable for linking
into the perf python module.

perf util: Make util its own library

2024-06-26T18:07:42+00:00

Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
  arch/common.c
  scripts/perl/Perf-Trace-Util/Context.c
  scripts/python/Perf-Trace-Util/Context.c
are made part of this library.
