2019-09-25libperf: Add perf_evlist__poll() functionJiri Olsa3-3/+3

2019-09-25perf tools: No need to include internal/lib.h from util/util.hArnaldo Carvalho de Melo1-0/+1
That was done just to have users of writen() and readn(), that before had their prototypes in util/util.h to get it without having to add an include for internal/lib.h, but the right way is to add it and by now all places already do it. Fix a fallout were readlink() was used but unistd.h was being obtained by luck thru util.h -> internal/lib.h, now to check why unistd.h is being included there...

2019-09-25libperf: Move 'page_size' global variable to libperfJiri Olsa2-2/+2
We need the 'page_size' variable in libperf, so move it there. Add a libperf_init() as a global libperf init function to obtain this value via sysconf() at tool start. Committer notes: Add internal/lib.h to tools/perf/ files using 'page_size', sometimes replacing util.h with it if that was the only reason for having util.h included.

2019-09-25perf evlist: Adopt backwards ring buffer state enumArnaldo Carvalho de Melo11-0/+11
As this isn't used at all in mmap.h but in evlist.h, so to cut down the header dependency tree, move it to where it is used. Also add mmap.h to the places using it but previously getting it indirectly via evlist.h. Add missing pthread.h to evlist.h, as it has a pthread_t struct member and was getting the header via mmap.h. Noticed while processing a Jiri's libperf batch touching mmap.h, where almost everything gets rebuilt because evlist.h is so popular, so cut down't this rebuild the world party.

2019-09-20perf session: Return error code for perf_session__new() function on failureMamatha Inamdar1-2/+3
This patch is to return error code of perf_new_session function on failure instead of NULL. Test Results: Before Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 0 $ After Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 254 $ Committer notes: Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(..., session), i.e. we need to pass zero in case of failure, which was the case before when NULL was returned by perf_session__new() for failure, but now we need to negate the result of IS_ERR(session) to respect that TEST_ASSERT_VAL) expectation of zero meaning failure.

2019-09-20perf tools: Remove debug.h from places where it is not neededArnaldo Carvalho de Melo1-1/+0
Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

2019-08-22perf cpumap: Remove needless includes from cpumap.hArnaldo Carvalho de Melo1-0/+1
The util/cpumap.h file doesn't use anything in refcount.h not in debug.h, it needs just a forward reference to 'struct cpu_map_data', that is defined in util/event.h and cpumap.h was getting indirectly via, of all things, debug.h Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-mtjww98yptt4ppo6g2blavg5@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-08-22perf tests: Add missing counts.hArnaldo Carvalho de Melo2-0/+2
Those are getting counts.h via evsel.h, that don't strictly need counts.h, just forward declarations for some structs, so add it here before we remove it from there.

2019-08-12perf test vfs_getname: Disable ~/.perfconfig to get default outputArnaldo Carvalho de Melo1-0/+4
To get the expected output we have to ignore whatever changes the user has in its ~/.perfconfig file, so set PERF_CONFIG to /dev/null to achieve that. Before: # egrep 'trace|show_' ~/.perfconfig [trace] show_zeros = yes show_duration = no show_timestamp = no show_arg_names = no show_prefix = yes # echo $PERF_CONFIG # perf test "trace + vfs_getname" 70: Check open filename arg using perf trace + vfs_getname: FAILED! # export PERF_CONFIG=/dev/null # perf test "trace + vfs_getname" 70: Check open filename arg using perf trace + vfs_getname: Ok # After: # egrep 'trace|show_' ~/.perfconfig [trace] show_zeros = yes show_duration = no show_timestamp = no show_arg_names = no show_prefix = yes # echo $PERF_CONFIG # perf test "trace + vfs_getname" 70: Check open filename arg using perf trace + vfs_getname: Ok # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Taeung Song <treeze.taeung@gmail.com> Link: https://lkml.kernel.org/n/tip-3up27pexg5i3exuzqrvt4m8u@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
