From e2be06662c1f310b60a3929f3fc944809c067307 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 16 Jun 2023 18:57:48 -0300 Subject: [PATCH] perf print-events: Export is_event_supported() Will be used when checking if we can encode the PMU number in perf_event_attr.type, part of the logic to use in hybrid systems (multiple types of CPUs, such as Intel's (Alder Lake, etc) or ARM's big.LITTLE).
