It's about 25% CPU and 75% interconnect, but with drivers/bus/ languishing without an obvious maintainer or tree, Olof and I agreed to keep all of these PMU patches together. I suspect a whole load of code from drivers/bus/arm-* can be moved under drivers/perf/, so that's on the radar for the future.

For this to work, either your bootloader needs to enable the CDMM
|
|
region at an unused physical address on the boot CPU, or else your

platform code needs to implement mips_cdmm_phys_base() (see

asm/cdmm.h).
