Hi Sylwester, When I tested this patchset on Odroid-U3, After setting 0 bps by interconnect[1][2], the frequency of devfreq devs sustain the high frequency according to the pm qos request. So, I try to find the cause of this situation. In result, it seems that interconnect exynos driver updates

[PATCH v7 0/6] Exynos: Simple QoS for exynos-bus using interconnect

2020-10-30 Thread Sylwester Nawrocki
This patchset adds interconnect API support for the Exynos SoC "samsung, exynos-bus" compatible devices, which already have their corresponding exynos-bus driver in the devfreq subsystem. Complementing the devfreq driver with an interconnect functionality allows to ensure the QoS requirements
