0179a913 - PM / devfreq: event: Add new Exynos NoC probe driver

Thu, 07 Apr 2016 02:29:11 +0000

PM / devfreq: event: Add new Exynos NoC probe driverThis patch adds NoC (Network on Chip) Probe driver which providesthe primitive values to get the performance data. The packets that the Networkon Chip (NoC) probes detects are transported over the network infrastructure.Exynos542x bus has multiple NoC probes to provide bandwidth information aboutbehavior of the SoC that you can use while analyzing system performance.Signed-off-by: Chanwoo Choi Tested-by: Markus Reichl Tested-by: Anand Moon Reviewed-by: Krzysztof Kozlowski List of files: /linux-6.15/drivers/devfreq/event/Makefile

f262f28c - PM / devfreq: event: Add devfreq_event class

Mon, 26 Jan 2015 04:16:27 +0000

PM / devfreq: event: Add devfreq_event classThis patch adds a new class in devfreq, devfreq_event, which providesraw data (e.g., memory bus utilization, GPU utilization) for devfreqgovernors.- devfreq_event device : Provides raw data for a governor of a devfreq device- devfreq device : Monitors device state and changes frequency/voltage of the device using the raw data from its devfreq_event device.A devfreq device dertermines performance states (normally the frequencyand the voltage vlues) based on the results its designtated devfreq governor:e.g., ondemand, performance, powersave.In order to give such results required by a devfreq device, the devfreqgovernor requires data that indicates the performance requirement givento the devfreq device. The conventional (previous) implementatino ofdevfreq subsystem requires a devfreq device driver to implement its ownmechanism to acquire performance requirement for its governor. However,there had been issues with such requirements:1. Although performance requirement of such devices is usually acquired from common devices (PMU/PPMU), we do not have any abstract structure to represent them properly.2. Such performance requirement devices (PMU/PPMU) are actual hardware pieces that may be represented by Device Tree directly while devfreq device itself is a virtual entity that are not considered to be represented by Device Tree according to Device Tree folks.In order to address such issues, a devferq_event device (represented bythis patch) provides a template for device drivers representingperformance monitoring unit, which gives the basic or raw data forpreformance requirement, which in turn, is required by devfreq governors.The following description explains the feature of two kind of devfreq class:- devfreq class (existing) : devfreq consumer device use raw data from devfreq_event device for determining proper current system state and change voltage/frequency dynamically using various governors.- devfreq_event class (new) : Provide measured raw data to devfreq device for governorCc: MyungJoo Ham Cc: Kyungmin Park Signed-off-by: Chanwoo Choi [Commit message rewritten & conflict resolved by MyungJoo]Signed-off-by: MyungJoo Ham List of files: /linux-6.15/drivers/devfreq/event/Makefile
