Some applications (e.g. Kodi) use tvservice APIs to manage HDMI modes, power state, EDID etc. directly through VideoCore. After these manipulations VideoCore may loose its state and needs to be resynced with ARM. Under Linux this problem is worked around using fbset utility that recreates framebuffer. Since there is no fbset utility in FreeBSD we provide sysctl for userland apps to get system back into normal mode.
