Message-Id: <20190503094409.3499-3-quentin.perret@arm.com> Date: Fri, 3 May 2019 10:44:08 +0100 From: Quentin Perret <quentin.perret@....com> To: edubezval@...il.com, rui.zhang@...el.com, javi.merino@...nel.org, viresh.kumar@...aro.org, amit.kachhap@...il.com, rjw@...ysocki.net, will.deacon@....com, catalin.marinas@....com Cc: daniel.lezcano@...aro.org, dietmar.eggemann@....com, ionela.voinescu@....com, quentin.perret@....com, mka@...omium.org, linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH v3 2/3] PM / EM: Expose perf domain struct In the current state, the perf_domain struct is fully defined only when CONFIG_ENERGY_MODEL=y. Since we need to write code that compiles both with or without that option in the thermal framework, make sure to actually define the struct regardless of the config option. That allows to avoid using stubbed accessor functions all the time in code paths that use the EM.
