Here are 2 small patches which adds support of SDT probes arguments: $ perf record -e sdt_libfoo:table_frob -e sdt_libfoo:table_diddle test_sdt $ perf script test_sdt ... 666.255678: sdt_libfoo:table_frob: (4004d7) arg0=0 arg1=0 test_sdt ... 666.255683: sdt_libfoo:table_diddle: (40051a) arg0=0 arg1=0 test_sdt ... 666.255686: sdt_libfoo:table_frob: (4004d7) arg0=1 arg1=2 test_sdt ... 666.255689: sdt_libfoo:table_diddle: (40051a) arg0=3 arg1=4 test_sdt ... 666.255692: sdt_libfoo:table_frob: (4004d7) arg0=2 arg1=4 test_sdt ... 666.255694: sdt_libfoo:table_diddle: (40051a) arg0=6 arg1=8 The patches were generated against tip/perf/core.
