With this patch, it seems perf tool has some problems in capturing the
kernel data with Intel PT.
Running the following commands, the size of perf.data is very small, and
perf script can't find any valid records.
perf record -e intel_pt//u -- /bin/ls
perf script --insn-trace
Hi,
I'm on leave (and should really go back to relaxing :>), returning on 2nd
Jan so can't really dig into this.
But I tried it on my intel box and it 'works on my machine' with and
without patch with commands provided, so I'm not sure this is actually a
product of this change (which shouldn't impact this).
Zide Chen, can you try with and without this patch to see if it
introduces the issue?
