2019-09-26perf unwind: Fix libunwind build failure on i386 systemsArnaldo Carvalho de Melo1-1/+1
Naresh Kamboju reported, that on the i386 build pr_err() doesn't get defined properly due to header ordering: perf-in.o: In function `libunwind__x86_reg_id': tools/perf/util/libunwind/../../arch/x86/util/unwind-libunwind.c:109: undefined reference to `pr_err' Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
2019-09-25perf parser: Remove needless include directivesArnaldo Carvalho de Melo1-3/+0
They go on accumulating there like the debug.h one, that was introduced here: f23610245c1a ("perf list: Add debug support for outputing alias string") But then, when that need is removed via: 2073ad3326b7 ("perf tools: Factor out PMU matching in parser") The thing stays there, so continue the house cleaning spree... list.h not needed, no macros from there are used, and 'struct list_head' is in linux/types.h, ditto for util.h, no need for that as well.

2019-09-25perf build: Add detection of java-11-openjdk-devel packageThomas Richter1-1/+1
With Java 11 there is no seperate JRE anymore. Details: https://coderanch.com/t/701603/java/JRE-JDK Therefore the detection of the JRE needs to be adapted. This change works for s390 and x86.

2019-09-25perf evlist: Fix access of freed id arraysAndi Kleen1-1/+1
I'm not fully sure if this is the correct fix, but without this I get crashes on more complex perf stat metric usages. The problem is that part of the state gets freed when a weak group fails, but then is later still used. Just don't free the ids, we're going to reuse them anyways on the weak group retry. For example: % perf stat -M IpB,IpCall,IpTB,IPC,Retiring_SMT,Frontend_Bound_SMT,Kernel_Utilization,CPU_Utilization --metric-only -a -I 1000 sleep 2 crashes and gives in valgrind: =21527== Invalid write of size 8 ==21527== at 0x4EE582: hlist_add_head (list.h:644) ==21527== by 0x4EFD3C: perf_evlist__id_hash (evlist.c:477) ==21527== by 0x4EFD99: perf_evlist__id_add (evlist.c:483) ==21527== by 0x4EFF15: perf_evlist__id_add_fd (evlist.c:524) ==21527== by 0x4FC693: store_evsel_ids (evsel.c:2969) ==21527== by 0x4FC76C: perf_evsel__store_ids (evsel.c:2986) ==21527== by 0x450DA7: __run_perf_stat (builtin-stat.c:519) ==21527== by 0x451285: run_perf_stat (builtin-stat.c:636) ==21527== by 0x454619: cmd_stat (builtin-stat.c:1966) ==21527== by 0x4D557D: run_builtin (perf.c:310) ==21527== by 0x4D57EA: handle_internal_command (perf.c:362) ==21527== by 0x4D5931: run_argv (perf.c:406) ==21527== Address 0x12e3f008 is 104 bytes inside a block of size 2,056 free'd ==21527== at 0x4839A0C: free (vg_replace_malloc.c:540) ==21527== by 0x627139: xyarray__delete (xyarray.c:32) ==21527== by 0x4F6BE4: perf_evsel__free_id (evsel.c:1253) ==21527== by 0x4FA11F: evsel__close (evsel.c:1994) ==21527== by 0x4F30A3: perf_evlist__reset_weak_group (evlist.c:1783) ==21527== by 0x450B47: __run_perf_stat (builtin-stat.c:466) ==21527== by 0x451285: run_perf_stat (builtin-stat.c:636) ==21527== by 0x454619: cmd_stat (builtin-stat.c:1966) ==21527== by 0x4D557D: run_builtin (perf.c:310) ==21527== by 0x4D57EA: handle_internal_command (perf.c:362) ==21527== by 0x4D5931: run_argv (perf.c:406) ==21527== by 0x4D5CAE: main (perf.c:531) ==21527== Block was alloc'd at ==21527== at 0x483AB1A: calloc (vg_replace_malloc.c:762) ==21527== by 0x627024: zalloc (zalloc.c:8) ==21527== by 0x627088: xyarray__new (xyarray.c:10) ==21527== by 0x4F6B20: perf_evsel__alloc_id (evsel.c:1237) ==21527== by 0x4FC74E: perf_evsel__store_ids (evsel.c:2983) ==21527== by 0x450DA7: __run_perf_stat (builtin-stat.c:519) ==21527== by 0x451285: run_perf_stat (builtin-stat.c:636) ==21527== by 0x454619: cmd_stat (builtin-stat.c:1966) ==21527== by 0x4D557D: run_builtin (perf.c:310) ==21527== by 0x4D57EA: handle_internal_command (perf.c:362) ==21527== by 0x4D5931: run_argv (perf.c:406) ==21527== by 0x4D5CAE: main (perf.c:531) Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Link: http://lore.kernel.org/lkml/20190923233339.25326-1-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-09-25perf evlist: Adopt backwards ring buffer state enumArnaldo Carvalho de Melo26-29/+53
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.
