Subject: [RFC PATCH v2 1/5] pci_ids: Add Hygon Family 0x18 DF device IDs
Date: Thu, 23 Apr 2026 14:04:08 +0800 [thread overview]
Message-ID: <20260423060420.1785357-2-wanglin@open-hieco.net> (raw)
In-Reply-To: <20260423060420.1785357-1-wanglin@open-hieco.net>
Add the PCI device IDs required to discover Hygon Family 0x18 Data Fabric
functions.
Hygon systems expose DF-related PCI functions using PCI_VENDOR_ID_HYGON.
All device IDs are defined with Hygon-specific names and explicit numeric
values.
