Subject: [PATCH 2/2] PCI: switchtec: Add Gen6 secure switches to NTB DMA alias quirk
Date: Tue, 3 Nov 2026 11:00:33 -0600 [thread overview]
Message-ID: <20261103170033.471034-3-logang@deltatee.com> (raw)
In-Reply-To: <20261103170033.471034-1-logang@deltatee.com>
Add the Gen6 PFXs and PSXs secure switch device IDs (48XG6 and 64XG6)
to the quirk_switchtec_ntb_dma_alias PCI fixup table. Without them,
DMA transactions from these switches' NTB function are not given the
correct requester ID alias, which can misdirect them under an IOMMU.
