Hello Stephane,
Ah, that explains the question I got last week.
The bulk of the events in my patch are defined in the
ARM Architecture Reference Manual,
https://static.docs.arm.com/ddi0487/ca/DDI0487C_a_armv8_arm.pdf
Section K3.1 ARM Recommendataions for IMPLEMENTATION
DEFINED events, and D5.10.3 Common Event Numbers.
There are a few events that are ThunderX2 specific described in
the Software Optimization Guide, but that document is available
only through our support site. At one point there was an NDA
involved. I don't know the document status since we announced
GA yesterday.
Of those few events, only one was used by PAPI.
What kind of statement would you need from Cavium?
Best Regards,
Steve Walk
Cavium

I cannot merge until I have a proof that the information used to build the
tables is publicly available somewhere.
So far no one has been able to point me to a web page or a PDF with the PMU
documentation.
Or we need a statement from Cavium authorizing the release of the event table
as build in the patch.

Hi Steve,
I wonder if it might have gotten lost or missed on:
https://sourceforge.net/p/perfmon2/libpfm4/merge-requests/
There are some other merges still open there. It looks like some of those
merge requests should also be closed as they are already merged in:
s390/cpumf: add support for IBM z13/z13s counters
s390/cpumf: check for counter facility availability
See the Cavium ThunderX and ThunderX2:
8 open Add Cavium ThunderX2 /u/swalk-cavium/perfmon2/ Steve
Walk 2018-03-20 2018-03-20
10 open Add Cavium ThunderX /u/druizmu/perfmon2/ Daniel Ruiz
2018-04-27 2018-04-27
