Hello Manuel,
that's a very nice interesting piece of code! Thank you very much!
Now two different questions arise:
* still, is this possible through regular perf binary from the
linux kernel?
* with respect to your code, I observe that the data region for the
PEBS collected samples is pointed by metadata_page. However, when
printing its contents through print_samples the output does not print
time-stamps. Are the time-stamps collected? If so, how can one access to
that information?
Thank you very much in advance!!

Yes you can. I wrote a small "memory not" for how to do this while
trying to enable memory sampling:

I also wrote some code exampl here:

Hello list,
is there any way to configure perf to sample memory references
through PEBS and enable the Load Latency Performance Monitoring
Facility (section 18.7.1.2 from the Intel 64 and IA-32 Architectures
Software Developer's Manual).
Thank you very much in advance.
