The Intel(R) Mesh 2 PCIe Registers - 09A4 is a component related to the Intel processor architecture, specifically tied to the PCI Express (PCIe) system interface on Intel's Ice Lake (ICX) or possibly later processor series. The "Mesh" part refers to the high-speed communication architecture within the processor that connects various cores and other components, while PCIe is a high-speed interface used for connecting various peripherals to the CPU (like GPUs, storage devices, etc.).

The "09A4" part refers to a specific identifier for the driver or device. It is often seen in the Device Manager under "System Devices" or similar, typically related to chipset drivers or the platform controller.
