Hello, This series exposes global performance counters (PCOUNTER) to the userspace through the nvif interface by reworking most of the code related to the PM engine. This interface will allow the userspace to control and monitor complex hardware events like the proprietary driver already does, for example with CUPTI and PerfKit. For now, this series only exposes performance counters on NV50,
