libperf: Fix install_pkgconfig target

2022-12-16T13:04:06+00:00

Commit 47e02b94a4c98dcc ("tools lib perf: Add dependency test to install_headers")
misses the notion of $(DESTDIR_SQ) for install_pkgconfig target, which leads to
error:

  install: cannot create regular file '/usr/lib64/pkgconfig/libperf.pc': Permission denied
  make: *** [Makefile:210: install_pkgconfig] Error 1

tools lib perf: Add dependency test to install_headers

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

Compute the headers to be installed from their source headers and make
each have its own build target to install it. Using dependencies
avoids headers being reinstalled and getting a new timestamp which
then causes files that depend on the header to be rebuilt.

tools lib perf: Make install_headers clearer

2022-11-20T14:32:23+00:00

Add libperf to the name so that this install_headers build appears
different to similar targets in different libraries.

libperf: Add missing 'struct perf_cpu_map' forward declaration to perf/cpumap.h

2022-11-16T19:00:49+00:00

The perf/cpumap.h header is getting the 'struct perf_cpu_map' forward
declaration by luck, add it.

libperf: Remove recursive perf/cpumap.h include from perf/cpumap.h

2022-11-16T19:00:49+00:00

It just hits the header guard, becoming a no-op, ditch it.

tools lib perf: Add missing install headers

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

Headers necessary for the perf build. Note, internal headers are also
installed as these are necessary for the build.

libperf: Do not include non-UAPI linux/compiler.h header

2022-10-14T13:44:20+00:00

Its just for that __packed define, so use it expanded as __attribute__((packed)),
like the other files in /usr/include do.

This was problem was preventing building the libperf examples on ALT
Linux and Fedora 35, fix it.

perf tools: Remove special handling of system-wide evsel

2022-10-06T11:03:53+00:00

For system-wide evsels, the thread map should be dummy - i.e. it has a
single entry of -1.  But the code guarantees such a thread map, so no
need to handle it specially.

No functional change intended.

libperf: Propagate maps only if necessary

2022-10-06T11:03:53+00:00

The current code propagate evsel's cpu map settings to evlist when it's
added to an evlist.  But the evlist->all_cpus and each evsel's cpus will
be updated in perf_evlist__set_maps() later.  No need to do it before
evlist's cpus are set actually.

In fact it discards this intermediate all_cpus maps at the beginning
of perf_evlist__set_maps().  Let's not do this.  It's only needed when
an evsel is added after the evlist cpu/thread maps are set.

libperf: Populate system-wide evsel maps

2022-10-06T11:03:53+00:00

Setting proper cpu and thread maps for system wide evsels regardless of
user requested cpu in __perf_evlist__propagate_maps().  Those evsels
need to be active on all cpus always.  Do it in the libperf so that we
can guarantee it has proper maps.
