Besar Wicaksono	bce61d5c57	perf: arm_cspmu: nvidia: monitor all ports by default ... Some NVIDIA PMUs like the NVLINK-C2C, CNVLINK, and PCIE PMU provide port filtering. If the port filter is set to zero, the counter of these PMUs will not capture any event. To avoid meaningless experiment, the driver sets the port filter value to a default non-zero value.
