Subject: [PATCH v1 3/3] PCI: Add PCI1008 to switchtec NTB DMA alias quirk
Date: Tue, 14 Jul 2026 15:20:10 -0600 [thread overview]
Message-ID: <20260714212010.230606-4-logang@deltatee.com> (raw)
In-Reply-To: <20260714212010.230606-1-logang@deltatee.com>
Add the PCI1008 device ID to the quirk_switchtec_ntb_dma_alias
PCI fixup table. Without it, DMA transactions from a PCI1008 switch's
NTB function are not given the correct requester ID alias, which can
misdirect them under an IOMMU.
