From b6c00fb9949fbd073e651a77aa75faca978cf2a6 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Wed, 4 Jan 2023 12:13:41 -0800 Subject: [PATCH] perf: Add PMU_FORMAT_ATTR_SHOW The macro PMU_FORMAT_ATTR facilitates the definition of both the "show" function and "format_attr". But it only works for a non-hybrid platform. For a hybrid platform, the name "format_attr_hybrid_" is used. The definition of the "show" function can be shared between a non-hybrid platform and a hybrid platform. Add a new macro PMU_FORMAT_ATTR_SHOW. No functional change. The PMU_FORMAT_ATTR_SHOW will be used in the following patch.
