I was curious as I don’t have much knowledge about the graphic card PCI Express Advanced Error Reporting. What are its functions and the related mechanism to it?
So to answer your question, enhancing the fact that PCI Express error signaling can only be directing in the PCIe link. However, the advance error capability is basically implemented with PCIe advance error reporting ability scheme or structure, in order to enhance the users for quicker error reporting. With the help of this capability, it itself detects the occurred error, and immediately sends an error message to the root port.
This port is associated with its pecking order. The PCI advance error reporting driver is also be termed as a PCIe bus service driver. The mechanism is also quite simple to understand. So it allows the PCIÂ Express AER driver to indulge about the error to ask the PCI component to determine what problem raised and precisely gain knowledge about it
