this series makes use of the load counters we can use to get information about the current load of the gpu. This series includes the needed pmu bits and a debugfs interface to read them out. Currently the values are between 0 and 255, because it is much easier to implement it this way on the pmu. Karol Herbst (4): subdev/pmu/fuc: add gk104 pmu/fuc: add macros for pdaemon pwr counters

these are usually used for dynamic reclocking on gt215 and newer The counters are used to get the load of the core, memory, video and pcie loads currently I expose the loads through a debugfs "current_load" file, but I want to move that to nvif and just add a wrapper around that in debugfs for convenience Anyway there are still some issues I would like to discuss: 1. currently the

Using nvif would have the advantage, that userspace tools can easily get loads
