Subject: [for-next][PATCH 4/9] PM: tracing: Hide psci_domain_idle events under ARM_PSCI_CPUIDLE
Date: Fri, 25 Jul 2025 08:41:49 -0400 [thread overview]
Message-ID: <20250725124210.936089481@kernel.org> (raw)
In-Reply-To: 20250725124145.391996103@kernel.org
From: Steven Rostedt <rostedt@goodmis.org>
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.
