[PATCH 5/6] x86/apic/msi: Use Real PCI DMA device when configuring IRTE

2020-07-28 Thread Jon Derrick
VMD retransmits child device MSI/X with the VMD endpoint's requester-id. In order to support direct interrupt remapping of VMD child devices, ensure that the IRTE is programmed with the VMD endpoint's requester-id using pci_real_dma_dev(). Reviewed-by: Andy Shevchenko Signed-off-by: Jon Derrick
