From 4a899c58df4378f8ec49df0fb593f02b798c29d3 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 14 Dec 2021 14:16:14 +0000 Subject: [PATCH] arm64: perf: Simplify registration boilerplate With the trend for per-core events moving to userspace JSON, registering names for PMUv3 implementations is increasingly a pure boilerplate exercise. Let's wrap things a step further so we can generate the basic PMUv3 init function with a macro invocation, and reduce further new addition to just 2 lines each.
