Dear Sirs, I used to asked Andy about PCounter and Samba a year ago. Last weekend I've just tried PCounter V.2 for NT and Samba the latest main brance. Here is the result. I set up 1 NT PDC and 1 standalone NT server (not a PDC, just a standalone). Then I installed PCounter on the standalone server. The standalond server didn't have an...

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 expos...

...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.
