From e64397f81c5422d5323f5f9a0fd2438e4c403015 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 12 Jun 2025 10:53:12 -0400 Subject: [PATCH] PM: tracing: Hide psci_domain_idle events under ARM_PSCI_CPUIDLE The events psci_domain_idle_enter and psci_domain_idle_exit events are only called when CONFIG_ARM_PSCI_CPUIDLE is defined. As each event can take up to 5K (less for DEFINE_EVENT()) regardless if they are used or not, it's best not to define them when they are not used. Add #ifdef around these events when they are not used.
