Since it is not yet that generally available, avoid testing for the
presence of libcoresight in the fast path test-all.bin feature test.

I.e. right now, in my system test-all.bin is failing all the time since
Fedora29 doesn't have libopencsd available:
$ cat /tmp/build/perf/feature/test-all.make.output
In file included from test-all.c:174:

#include <opencsd/c_api/opencsd_c_api.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
See:
6ab2b762befd ("perf build: Disable libbabeltrace check by default")
For the rationale, as soon as libopencsd becomes more generally packaged
and available, we do the same thing we did with babeltrace, enabling it
by default, as done in:
24787afbcd01 ("perf tools: Enable LIBBABELTRACE by default")
For now, to explicitely ask for opencsd, make sure you have it installed
and use:
make -C tools/perf CORESIGHT=1
The feature test output will be there as an empty file:
$ ls -la /tmp/build/perf/feature/test-libopencsd.make.output
Because the binary used for the feature check was successfully built:
$ ls -la /tmp/build/perf/feature/test-libopencsd.bin

And the resulting perf binary will be linked with it:

$ ldd ~/bin/perf | grep opencsd

To make sure this gets built before pushing things upstream I have a
ubuntu:19.04-x-arm64 container that has:
[root@quaco x-arm64]# grep CORESIGHT Dockerfile
ENV EXTRA_MAKE_ARGS=CORESIGHT=1
[root@quaco x-arm64]#
So that I always build with libopencsd before pushing things upstream.

| H A D | Makefile.perf | 1c3b28fd Tue Feb 12 11:37:15 CST 2019 Arnaldo Carvalho de Melo <acme@redhat.com> perf coresight: Do not test for libopencsd by default
Since it is not yet that generally available, avoid testing for the
presence of libcoresight in the fast path test-all.bin feature test.
# dnf search opencsd
No matches found.
# dnf search OpenCSD
No matches found.
# cat /etc/fedora-release
Fedora release 29 (Twenty Nine)
#
I.e. right now, in my system test-all.bin is failing all the time since
Fedora29 doesn't have libopencsd available:
$ cat /tmp/build/perf/feature/test-all.make.output
In file included from test-all.c:174:
test-libopencsd.c:2:10: fatal error: opencsd/c_api/opencsd_c_api.h: No such file or directory
#include <opencsd/c_api/opencsd_c_api.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
See:
6ab2b762befd ("perf build: Disable libbabeltrace check by default")
For the rationale, as soon as libopencsd becomes more generally packaged
and available, we do the same thing we did with babeltrace, enabling it
by default, as done in:
24787afbcd01 ("perf tools: Enable LIBBABELTRACE by default")
For now, to explicitely ask for opencsd, make sure you have it installed
and use:
make -C tools/perf CORESIGHT=1
The feature test output will be there as an empty file:
$ ls -la /tmp/build/perf/feature/test-libopencsd.make.output
Because the binary used for the feature check was successfully built:
$ ls -la /tmp/build/perf/feature/test-libopencsd.bin
-rwxrwxr-x. 1 acme acme 18336 Feb 12 14:49 /tmp/build/perf/feature/test-libopencsd.bin
$ ldd /tmp/build/perf/feature/test-libopencsd.bin
linux-vdso.so.1 (0x00007fffe18cc000)
libopencsd_c_api.so.0 => /lib64/libopencsd_c_api.so.0 (0x00007fb8e67f6000)
libopencsd.so.0 => /lib64/libopencsd.so.0 (0x00007fb8e676f000)
libc.so.6 => /lib64/libc.so.6 (0x00007fb8e65a9000)
libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fb8e6411000)

/lib64/ld-linux-x86-64.so.2 (0x00007fb8e6828000)
$
And the resulting perf binary will be linked with it:
-rw-rw-r--. 1 acme acme 0 Feb 12 14:49 /tmp/build/perf/feature/test-libopencsd.make.output
$ ldd ~/bin/perf | grep opencsd
libopencsd_c_api.so.0 => /lib64/libopencsd_c_api.so.0 (0x00007fd43097f000)
libopencsd.so.0 => /lib64/libopencsd.so.0 (0x00007fd4308f8000)
$
To make sure this gets built before pushing things upstream I have a
ubuntu:19.04-x-arm64 container that has:
[root@quaco x-arm64]# grep CORESIGHT Dockerfile
ENV EXTRA_MAKE_ARGS=CORESIGHT=1
[root@quaco x-arm64]#
So that I always build with libopencsd before pushing things upstream.
