Talking about build tests, you forgot to add it there, like I did below, I'll eventually do it, as it is opt-in, no biggie at this point. I'll install libpfm-devel that is in fedora and do further tests, later today. - Arnaldo commit a01c205e3c4cd6d134317413f2dc3129c4ab7a5a Author: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> Date: Fri May 29 11:31:23 2020 -0300 perf build: Add NO_SYSCALL_TABLE=1 to the build tests So that we make sure that even on x86-64 and other architectures where that is the default method we test build the fallback to libaudit that other architectures use. I.e. now this line got added to: $ make -C tools/perf build-test <SNIP> make_no_syscall_tbl_O: cd . && make NO_SYSCALL_TABLE=1 FEATURES_DUMP=/home/acme/git/perf/tools/perf/BUILD_TEST_FEATURE_DUMP -j12 O=/tmp/tmp.W0HtKR1mfr DESTDIR=/tmp/tmp.lNezgCVPzW <SNIP> $ Cc: Adrian Hunter <adrian.hunter@xxxxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxxxxx> Cc: Jiri Olsa <jolsa@xxxxxxxxxx> Cc: Namhyung Kim <namhyung@xxxxxxxxxx> Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> diff --git a/tools/perf/tests/make b/tools/perf/tests/make index 29ce0da7fca6..a4ffa3c7fcb6 100644 --- a/tools/perf/tests/make +++ b/tools/perf/tests/make @@ -88,6 +88,7 @@ make_no_libbpf_DEBUG := NO_LIBBPF=1 DEBUG=1 make_no_libcrypto := NO_LIBCRYPTO=1 make_with_babeltrace:= LIBBABELTRACE=1 make_no_sdt := NO_SDT=1 +make_no_syscall_tbl := NO_SYSCALL_TABLE=1 make_with_clangllvm := LIBCLANGLLVM=1 make_tags := tags make_cscope := cscope @@ -113,7 +114,7 @@ make_minimal += NO_DEMANGLE=1 NO_LIBELF=1 NO_LIBUNWIND=1 NO_BACKTRACE=1 make_minimal += NO_LIBNUMA=1 NO_LIBAUDIT=1 NO_LIBBIONIC=1 make_minimal += NO_LIBDW_DWARF_UNWIND=1 NO_AUXTRACE=1 NO_LIBBPF=1 make_minimal += NO_LIBCRYPTO=1 NO_SDT=1 NO_JVMTI=1 NO_LIBZSTD=1 -make_minimal += NO_LIBCAP=1 +make_minimal += NO_LIBCAP=1 NO_SYSCALL_TABLE=1 # $(run) contains all available tests run := make_pure @@ -146,6 +147,7 @@ run += make_no_libbionic run += make_no_auxtrace run += make_no_libbpf run += make_no_libbpf_DEBUG +run += make_no_syscall_tbl run += make_with_babeltrace run += make_with_clangllvm run += make_help
