Subject: [Patch v10 5/9] arm/topology: Populate arch_scale_thermal_pressure for arm platforms
Date: Fri, 21 Feb 2020 19:52:09 -0500	[thread overview]
Message-ID: <20200222005213.3873-6-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20200222005213.3873-1-thara.gopinath@linaro.org>

Hook up topology_get_thermal_pressure to arch_scale_thermal_pressure thus
enabling scheduler to retrieve instantaneous thermal pressure of a cpu.
