Hi,
Updating to mainline as of last night, I started seeing the following
error when running the perf report TUI:
0x46068 [0x8]: failed to process type: 68
This event is just PERF_RECORD_FINISHED_ROUND:
0x46068 [0x8]: event: 68
.
. ... raw event: size 8 bytes
. 0000: 44 00 00 00 00 00 08 00 D.......
0x46068 [0x8]: PERF_RECORD_FINISHED_ROUND
Which of course is not our error. It took me a while to find the real
culprit:
14c00-14c00 g exc_virt_0x4c00_system_call
A zero length symbol, which __symbol__inc_addr_samples() barfs on:
if (addr < sym->start || addr >= sym->end) {
...
return -ERANGE;
Seems like we have 3 bugs here:
1. Output the real source of the error instead of PERF_RECORD_FINISHED_ROUND
2. Don't exit the TUI if we find a sample on a zero length symbol
3. Why do we have zero length symbols in the first place? Does the recent
ppc64 exception clean up have something to do with it?
