To avoid having to add new entries to tools/perf/Makefile.perf prep socket.sh so that it can generate other socket table generators, such as the upcoming SOL_ socket level one. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
The script that generates the tables was named 'socket.sh', which is confusing, rename it to sockaddr.sh and make sure the related Makefile.perf targets also use the 'sockaddr' namespace. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
API headers from libbpf should not be accessed directly from the library's source directory. Instead, they should be exported with "make install_headers". Let's adjust perf's Makefile to install those headers locally when building libbpf. v2: - Fix $(LIBBPF_OUTPUT) when $(OUTPUT) is null. - Make sure the recipe for $(LIBBPF_OUTPUT) is not under a "ifdef".

Add a new dlfilter to show cycles.
Cycle counts are accumulated per CPU (or per thread if CPU is not recorded)
from IPC information, and printed together with the change since the last
print, at the start of each line. Separate counts are kept for branches,
instructions or other events.
Note also, the itrace A option can be useful to provide higher granularity
cycle information.
Example:
$ perf record -e intel_pt/cyc/u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.044 MB perf.data ]
