Subject: [PATCH v2 0/2] perf/arm-cmn: Add support for tertiary match group
Date: Thu, 7 Mar 2024 15:09:27 -0800 [thread overview]
Message-ID: <20240307230929.6233-1-ilkka@os.amperecomputing.com> (raw)
Tertiary match group was added to CMN-650 and newer implementations.
This patchset makes the parameters model specific to support properly
various models. Also, wp_config registers and filter groups numbers are
decoupled to enable the new match group.
v2:
* Use bitmap to track which WPs/DTMs are used by the event
* Dropped model specific parameters
* Addressed other Robin's comments regarding to sysfs, sanity-check
of wp arguments, and wp_combine check
v1:
