Logan Gunthorpe b02b0a6bcc iommu/amd: Support multiple PCI DMA aliases in IRQ Remapping ... [ Upstream commit 3c124435e8 ] Non-Transparent Bridge (NTB) devices (among others) may have many DMA aliases seeing the hardware will send requests with different device ids depending on their origin across the bridged hardware. See commit ad281ecf1c ("PCI: Add DMA alias quirk for Microsemi Switchtec NTB") for more information on this. The AMD IOMMU IRQ remapping functionality ignores all PCI aliases for IRQs so if devices send an interrupt from one of their aliases they will be blocked on AMD hardware with the IOMMU enabled. To fix this, ensure IRQ remapping is enabled for all aliases with MSI interrupts. This is analogous to the functionality added to the Intel IRQ remapping code in commit 3f0c625c6a ("iommu/vt-d: Allow interrupts from the entire bus for aliased devices") Signed-off-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Joerg Roedel <jroedel@suse.de> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-02-01 09:34:48 +00:00
