I tried it without modification, as well as with each alias individually. I get: Set context mapping for 0d:00.3 firewire_ohci 0000:0d:00.3: added OHCI v1.10 device as card 0, 4 IR + 4 IT contexts, quirks 0x11 dmar: DRHD: handling fault status reg 2 dmar: DMAR:[DMA Read] Request device [0d:00.0] fault addr fffff000 DMAR:[fault reason 02] Present bit in context entry is clear I think I need to see Set context mapping for 0d:00.0 before Set context mapping for 0d:00.3 in the log, but it's not there. I'd love to look into this and understand it properly, but I don't have time for the next four weeks. The devices are attached as follows: BDF, device ID 0d:00.0, e822 0d:00.1, e230 0d:00.3, e832 The kernel log is attached.

Hmm, there are only a few reasons why you'd never see 0d:00.3 followed by 0d:00.0... 1) dma_func_alias bit 0 isn't getting set on 0d:00.3; we are building with CONFIG_PCI_QUIRKS=y, right? 2) domain_context_mapping_one called from domain_context_mapping_cb returns !0; there's only one possible non-zero return for a non-vm, non-si domain 3) something is broken in the first loop of pci_for_each_dma_alias; I'm not seeing anything obvious Anyway, appreciate an debugging you're able to fit in, my only ricoh device has only function 0.

The existing quirk for these devices doesn't really solve the problem, re-implement it using the DMA alias iterator. We'll come back later and remove the existing quirk and dma_source interface.
