I am trying to monitor the PCIe throughput to an Nvidia K5200.
When there is activity on the GPU Bus interface Load detected by GPUz. eg I know I am doing a lot of PCIe Rd and Wr. I do not see the corresponding increase in PCIe activity identified by pcm-pci.
Is there anything special about GPU activity for these counters.

Same issue on 2 different machines
