Subject: [Patch v7 2/7] sched/topology: Add hook to read per cpu thermal pressure.
Date: Sat, 11 Jan 2020 10:59:01 -0500 [thread overview]
Message-ID: <1578758346-507-3-git-send-email-thara.gopinath@linaro.org> (raw)
In-Reply-To: <1578758346-507-1-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.
