I did not find in this patch the support for the C-Box Filter register
(SNBEP_C0_MSR_PMON_BOX_FILTER). Based on the description
in the manual, looks like a valuable filter to support, especially for
the core/thread filtering capability.
There is only one such filter per box, and it can be used by any events.
So looks like we have another offcore_resp style register to manage
here. Need to ensure the value of that filter is shared by all 4 counters.
If you were to support that, you'd have to enable the tid filter on the
CBox config regs and export that via sysfs. Also I assume you'd
pass the value of that filter either in config1 or in the upper 32 bits
of the config reg.
What's your take on that?
