2 bool "DEVFREQ-Event device Support"
4 The devfreq-event device provide the raw data and events which
5 indicate the current state of devfreq-event device. 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
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.
16 config DEVFREQ_EVENT_EXYNOS_NOCP
17 tristate "EXYNOS NoC (Network On Chip) Probe DEVFREQ event Driver"
18 depends on ARCH_EXYNOS || COMPILE_TEST
22 This add the devfreq-event driver for Exynos SoC. It provides NoC
23 (Network on Chip) Probe counters to measure the bandwidth of AXI bus.
25 config DEVFREQ_EVENT_EXYNOS_PPMU
26 tristate "EXYNOS PPMU (Platform Performance Monitoring Unit) DEVFREQ event Driver"
27 depends on ARCH_EXYNOS || COMPILE_TEST
30 This add the devfreq-event driver for Exynos SoC. It provides PPMU
31 (Platform Performance Monitoring Unit) counters to estimate the
32 utilization of each module.
34 config DEVFREQ_EVENT_ROCKCHIP_DFI
35 tristate "ROCKCHIP DFI DEVFREQ event Driver"
36 depends on ARCH_ROCKCHIP
38 This add the devfreq-event driver for Rockchip SoC. It provides DFI
39 (DDR Monitor Module) driver to count ddr load.
