From 1a6b0deb2b71d6e94497a284b9babce80b18cc7c Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 14 Nov 2025 14:05:45 -0800 Subject: [PATCH] perf header: Switch "cpu" for find_core_pmu in caps feature writing Writing currently fails on non-x86 and hybrid CPUs. Switch to the more regular find_core_pmu that is normally used in this case. Tested on hybrid alderlake system.
