Please refer to Section 18.3.2 ACPI Error Source of acpi spec v6.3. 
Links to the online versions of ACPI Spec 6.3 is
https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/18_ACPI_Platform_Error_Interfaces/error-source-discovery.html#acpi-error-source. 

Section 18.3.2.4 describes PCI Express Root Port AER Structure, section 
18.3.2.5 describes PCI Express Device AER Structure, section 18.3.2.6 
describes PCI Express/PCI-X Bridge AER Structure.
