 /** @file\r
   This file declares EFI Incompatible PCI Device Support Protocol\r
+  This protocol allows the PCI bus driver to support resource allocation for some PCI devices that do not comply\r
+  with the PCI Specification.\r
+  The EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL is used by the PCI bus driver\r
+  to support resource allocation for some PCI devices that do not comply with the PCI Specification.\r
+  This protocol can find some incompatible PCI devices and report their special resource\r
+  requirements to the PCI bus driver. The generic PCI bus driver does not have prior knowledge of\r
+  any incompatible PCI devices. It interfaces with the\r
+  EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL to find out if a device is\r
+  incompatible and to obtain the special configuration requirements for a specific incompatible PCI\r
+  device.\r
+  This protocol is optional, and only one instance of this protocol can be present in the system. If a\r
+  platform supports this protocol, this protocol is produced by a Driver Execution Environment\r
+  (DXE) driver and must be made available before the Boot Device Selection (BDS) phase. The PCI\r
+  bus driver will look for the presence of this protocol before it begins PCI enumeration.\r
