I think I am done reworking the series and getting to a point where I think it is basically finished. The configuration of the slots could be improved later on when working on dynamic reclocking, but for now it's good enough to report the current GPU utilization to userspace.
Patches 1-4 imeplement PMU commands to setup and readout the counters. Patches 5-6 lets Nouveau make use of 1-4. Patch 7 adds a debugfs file to readout basic GPU loads. In a follow up one could write a nice NVIF based interface for readoung out those values to provide them through GALLIUM_HUD. This feature is required to implement proper dynamic reclocking on GT215 and newer. On pre GT215 GPUs there is also PCOUNTERS, but this is ugly so that I only focus on dynamic reclocking starting with GT215 for now.
