Subject: [Patch v10 2/9] sched/topology: Add hook to read per cpu thermal pressure.
Date: Fri, 21 Feb 2020 19:52:06 -0500	[thread overview]
Message-ID: <20200222005213.3873-3-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20200222005213.3873-1-thara.gopinath@linaro.org>

Introduce arch_scale_thermal_pressure to retrieve per cpu thermal
pressure.

Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org>
---
v6->v7:
	- Renamed arch_scale_thermal_capacity to arch_cpu_thermal_pressure
	  as per review comments from Peter, Dietmar and Ionela.
v9->v10:
	- Renamed arch_cpu_thermal_pressure to arch_scale_thermal_pressure
	  as per review comments from Dietmar.
