dtpm.rst	Documentation/powercap/dtpm: Add documentation for dtpm The dynamic thermal and power management is a technique to dynamically adjust the power consumption of different devices in order to ensure a global thermal constraint. An userspace daemon is usually monitoring the temperature and the power to take immediate action on the device. The DTPM framework provides an unified API to userspace to act on the power. Document this framework. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Reviewed-by: Lukasz Luba <lukasz.luba@arm.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>	5 年前
powercap.rst	powercap: Add Power Limit4 support Modern Intel Mobile platforms support power limit4 (PL4), which is the SoC package level maximum power limit (in Watts). It can be used to preemptively limits potential SoC power to prevent power spikes from tripping the power adapter and battery over-current protection. This patch enables this feature by exposing package level peak power capping control to userspace via RAPL sysfs interface. With this, application like DTPF can modify PL4 power limit, the similar way of other package power limit (PL1). As this feature is not tested on previous generations, here it is enabled only for the platform that has been verified to work, for safety concerns.
