As an AI language model, I do not have access to the specific context in which this message was encountered. However, I can provide a general explanation of what this message could mean.
PCI device 0000:02:01.0 refers to a Peripheral Component Interconnect (PCI) device that is located at bus 2, device 1, and function 0. The message indicates that this device is not associated with any specific NUMA socket.
NUMA (Non-Uniform Memory Access) is a type of computer architecture where memory access times depend on the distance between the processor and memory. In a NUMA system, processors are grouped into nodes, and each node has its own memory bank. If a PCI device is connected to a specific NUMA node, it can access memory faster than if it were connected to a different node.
However, in this case, the message suggests that the PCI device is not connected to any specific NUMA socket, meaning that it may not be optimized for performance in a NUMA system. This could potentially lead to slower data transfer rates or other performance issues.
