(2023-07-05 12:23:00 -0700) ---------------------------------------------------------------- perf tools changes and fixes for v6.5: 2nd batch Build: - Allow to generate vmlinux.h from BTF using `make GEN_VMLINUX_H=1` and skip if the vmlinux has no BTF. - Replace deprecated clang -target xxx option by --target=xxx. perf record: - Print event attributes with well known type and config symbols in the debug output like below: # perf record -e cycles,cpu-clock -C0 -vv true ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) size 136 config 0 (PERF_COUNT_HW_CPU_CYCLES) { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|CPU|PERIOD|IDENTIFIER read_format ID disabled 1 inherit 1 freq 1 sample_id_all 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 5 ------------------------------------------------------------ perf_event_attr: type 1 (PERF_TYPE_SOFTWARE) size 136 config 0 (PERF_COUNT_SW_CPU_CLOCK) { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|CPU|PERIOD|IDENTIFIER read_format ID disabled 1 inherit 1 freq 1 sample_id_all 1 exclude_guest 1 - Update AMD IBS event error message since it now support per-process profiling but no priviledge filters. $ sudo perf record -e ibs_op//k -C 0 Error: AMD IBS doesn't support privilege filtering. Try again without the privilege modifiers (like 'k') at the end. perf lock contention: - Support CSV style output using -x option $ sudo perf lock con -ab -x, sleep 1 # output: contended, total wait, max wait, avg wait, type, caller 19, 194232, 21415, 10222, spinlock, process_one_work+0x1f0 15, 162748, 23843, 10849, rwsem:R, do_user_addr_fault+0x40e 4, 86740, 23415, 21685, rwlock:R, ep_poll_callback+0x2d 1, 84281, 84281, 84281, mutex, iwl_mvm_async_handlers_wk+0x135 8, 67608, 27404, 8451, spinlock, __queue_work+0x174 3, 58616, 31125, 19538, rwsem:W, do_mprotect_pkey+0xff 3, 52953, 21172, 17651, rwlock:W, do_epoll_wait+0x248 2, 30324, 19704, 15162, rwsem:R, do_madvise+0x3ad 1, 24619, 24619, 24619, spinlock, rcu_core+0xd4 - Add --output option to save the data to a file not to be interfered by other debug messages. Test: - Fix event parsing test on ARM where there's no raw PMU nor supports PERF_PMU_CAP_EXTENDED_HW_TYPE. - Update the lock contention test case for CSV output. - Fix a segfault in the daemon command test. Vendor events (JSON): - Add has_event() to check if the given event is available on system at runtime. On Intel machines, some transaction events may not be present when TSC extensions are disabled. - Update Intel event metrics. Misc: - Sort symbols by name using an external array of pointers instead of a rbtree node in the symbol. This will save 16-bytes or 24-bytes per symbol whether the sorting is actually requested or not. - Fix unwinding DWARF callstacks using libdw when --symfs option is used.
