PCI/DPC: Quirk PIO log size for Intel Raptor Lake Root Ports
[ Upstream commit 627c6db ] Commit 5459c0b ("PCI/DPC: Quirk PIO log size for certain Intel Root Ports") and commit 3b88034 ("PCI/DPC: Quirk PIO log size for Intel Ice Lake Root Ports") add quirks for Ice, Tiger and Alder Lake Root Ports. System firmware for Raptor Lake still has the bug, so Linux logs the warning below on several Raptor Lake systems like Dell Precision 3581 with Intel Raptor Lake processor (0W18NX) system firmware/BIOS version 1.10.1. pci 0000:00:07.0: [8086:a76e] type 01 class 0x060400 pci 0000:00:07.0: DPC: RP PIO log size 0 is invalid pci 0000:00:07.1: [8086:a73f] type 01 class 0x060400 pci 0000:00:07.1: DPC: RP PIO log size 0 is invalid Apply the quirk for Raptor Lake Root Ports as well. This also enables the DPC driver to dump the RP PIO Log registers when DPC is triggered.
