Providing input from PCI perspective only:
PCIe defines the the following error categories:
1. Correctable error
2. Uncorrectable non-fatal errors
3. Uncorrectable fatal errors
The do_recovery function needs to be called for both uncorrectable error
categories. (#2 and #3 above)
How these map to GHES error categories is out of know-how.
Below are references to some of the PCIe error docs:
