intel_stepping - Display the stepping information for an Intel GPU
intel_stepping is a tool to print the stepping information for an Intel GPU, along with the PCI ID and revision used to determine it. It requires root privilege to map the graphics device.
Not all the known stepping IDs or chipsets are included, so the output on some devices may not be as specific as possible.
