In the parse_events_multi_pmu_add() it passes the 'config' variable twice to parse_events_term__num() - one for config and another for loc_term. I'm not sure about the second one as it's converted to YYLTYPE variable. Asan reports it like below: In function ‘parse_events_term__num’, inlined from ‘parse_events_multi_pmu_add’ at util/parse-events.c:1602:6: util/parse-events.c:2653:64: error: array subscript ‘YYLTYPE[0]’ is partly outside array bounds of ‘char[8]’ [-Werror=array-bounds] 2653 | .err_term = loc_term ? loc_term->first_column : 0, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~ util/parse-events.c: In function ‘parse_events_multi_pmu_add’: util/parse-events.c:1587:15: note: object ‘config’ of size 8 1587 | char *config; | ^~~~~~ cc1: all warnings being treated as errors Signed-off-by:

Trace IDs are now dynamically allocated. Previously used the static association algorithm that is no longer used. The 'cpu * 2 + seed' was outdated and broken for systems with high core counts (>46). as it did not scale and was broken for larger core counts. Trace ID will now be sent in PERF_RECORD_AUX_OUTPUT_HW_ID record. Legacy ID algorithm renamed and retained for limited backward compatibility use. Reviewed-by:

The information to associate Trace ID and CPU will be changing. Drivers will start outputting this as a hardware ID packet in the data file which if present will be used in preference to the AUXINFO values. To prepare for this we provide a helper functions to do the individual ID mapping, and one to extract the IDs from the completed metadata blocks. Reviewed-by:

It can fail to collect lock stat from BPF for various reasons. For example, I've got a report that sometimes time calculation seems wrong in case of contended spinlocks.

Allow addr2line to be set either on the command line or via the perfconfig file. This doesn't currently work with llvm-addr2line as the addr2line code emits two things: 1) the address to decode, 2) a bogus ',' value. The expectation is the bogus value will generate: ?? ??:0 that terminates the addr2line reading. However, the output from llvm-addr2line is a single line with just the input ',' locking up the addr2line reading that is expecting a second line. Signed-off-by:

Commit 3c22ba52 ("perf vendor events powerpc: Update POWER9 events") added and updated power9 PMU JSON events. However some of the JSON events which are part of other.json and pipeline.json files, contains UTF-8 characters in their brief description. Having UTF-8 character could breaks the perf build on some distros. Fix this issue by removing the UTF-8 characters from other.json and pipeline.json files.

This is a follow up patch for the execve bench which is actually fork + execve, it makes sense to add the fork syscall benchmark to compare the execve part precisely. Some archs have no __NR_fork definition which is used only as a check condition to call test_fork(), let us just define it as -1 to avoid build error. Suggested-by:
