Description:
Hi! I'd like to include intel-cmt-cat Fedora package in EPEL. Fedora package BZ
is 1326301. Please also have a look here for more information about Fedora
package:
https://admin.fedoraproject.org/pkgdb/package/rpms/intel-cmt-cat/
I would appreciate a review so it can be packaged for EPEL.
More about the package -
Software package includes command line tool and the corresponding man page. The
tool allows to monitor LLC cache occupancy (CMT) and memory bandwidth (MBM) as
well as control/configure access to LLC (CAT & CDP). Through configuring cache
access, workloads can be isolated and their impact on other workloads can be
reduced. Several studies found it useful for improved server utilization and
service assurance. Example:

CAT and CDP are not enabled via any Linux framework at the moment. The tool
provides solution until kernel frameworks enable the technologies in question
and customers upgrade their kernels.
CMT and MBM can be used via Linux perf in kernels 4.1+ and 4.6+ respectively.
The tool depends only on x86 MSR kernel driver (arch/x86/kernel/msr.c) and C &
pthreads libraries. This is user space software and because it accesses MSR's
it needs adequate level of privilege.
