Subject: [Patch v9 2/8] sched/topology: Add hook to read per cpu thermal pressure.
Date: Tue, 28 Jan 2020 17:36:01 -0500	[thread overview]
Message-ID: <1580250967-4386-3-git-send-email-thara.gopinath@linaro.org> (raw)
In-Reply-To: <1580250967-4386-1-git-send-email-thara.gopinath@linaro.org>

Introduce arch_cpu_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.
