Revision 0957c29f78af7d890c4ac506eda8f76bfc5a137a authored by Bart Van Assche on 07 March 2017, 22:56:53 UTC, committed by Doug Ledford on 25 March 2017, 01:51:16 UTC
Avoid that the following error message is reported on the console
while loading an RDMA driver with I/O MMU support enabled:
DMAR: Allocating domain for mlx5_0 failed
Ensure that DMA mapping operations that use to_pci_dev() to
access to struct pci_dev see the correct PCI device. E.g. the s390
and powerpc DMA mapping operations use to_pci_dev() even with I/O
MMU support disabled.
This patch preserves the following changes of the DMA mapping updates
patch series:
- Introduction of dma_virt_ops.
- Removal of ib_device.dma_ops.
- Removal of struct ib_dma_mapping_ops.
- Removal of an if-statement from each ib_dma_*() operation.
- IB HW drivers no longer set dma_device directly.
