On an Android Pixel device (for example, the Pixel 6 X1 and A76 chips), I see memory frequency governors and different memory frequencies per core. For example, /sys/class/devfreq/gs_memlat_devfreq:devfreq_mif_cpu5_memlat@17000010/available_frequencies show the available frequencies for the memory of core 5.
Is there any official ARM document about the memory frequencies per core? For example, which cache hierarchies (or main memory, but I don't know how this is possible) this affects and how the memory governor influences snoops across cores.
