[PATCH v7 08/12] perf: Add perf_event_attr::config4
From: James Clark
Date: Thu Aug 14 2025 - 05:30:49 EST
Arm FEAT_SPE_FDS adds the ability to filter on the data source of a
packet using another 64-bits of event filtering control. As the existing
perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config4' field.
