The provided 6 data from devfreq-event device is used to monitor the state of 7 device and determine the suitable size of resource to reduce the 8 wasted resource. 9 10 The devfreq-event device can support the various type of events 11 (e.g., raw data, utilization, latency, bandwidth). The events 12 may be used by devfreq governor and other subsystem. 13 14if PM_DEVFREQ_EVENT 15 16config DEVFREQ_EVENT_EXYNOS_NOCP 17 tristate "EXYNOS NoC (Network On Chip) Probe DEVFREQ event Driver" 18 depends on ARCH_EXYNOS || COMPILE_TEST 19 select PM_OPP 20 select REGMAP_MMIO 21 help 22 This add the devfreq-event driver for Exynos SoC.
