Subject: [PATCH v2] ATA: ahci: Add Intel PCH-S RAID device ID
Date: Thu, 29 Oct 2026 15:00:03 +0100	[thread overview]
Message-ID: <20261029140004.6991-1-romanx.gardzinski@linux.intel.com> (raw)

When the Intel Nova Lake SATA controller is configured in RAID mode (rather
than AHCI), the generic entry in ahci_pci_tbl which matches any device with
the PCI class code for AHCI, is not sufficient, since the SATA controller
in RAID mode uses a different PCI class code.
