To request a PMD to be monitored, one have to write to the PMD before
the PMU is started. See perfmon_rw.c:
* it is not possible to read a PMD which was not requested:
* - explicitly written via pfm_write_pmds()
* - provided as a reg_smpl_pmds[] to another PMD during
* pfm_write_pmds()
*
However, with commit id d9899320399f8055ed79863d037dc3d9d37bbe66, this
is no longer possible for read only PMDs. Is there a another way of
marking a RO PMD?
Thanks,
