- Support device ID 0x28C1 and assume that BIOS has already enumerated the hierarchy below VMD and stored bus range info for OS to use (Nirmal Patel) - Add support for VMCONFIG BUS_RESTRICT_CFG=3, which makes it possible to enumerate downstream devices on Intel Arrow Lake-HX systems and probably others (Ali Alaei) - Observe _OSC negotiation for VMD hierarchy only when running on bare metal, not when running in a VM (Nirmal Patel) - Add Nova Lake (NVL) and Dunlow (DNL) Device IDs (Szymon Durawa) * pci/controller/vmd: PCI: vmd: Add Nova Lake (NVL) and Dunlow (DNL) Device IDs PCI: vmd: Only copy root bridge _OSC control flags in bare metal OS PCI: vmd: Handle BUS_RESTRICT_CFG value 3 for Arrow Lake-HX PCI: vmd: Add feature to scan BIOS-enumerated devices
