iommu/amd: Allow non-ATS devices in IOMMUv2 domains (2015-07-31 15:15:41
+0200)
----------------------------------------------------------------
IOMMU Fixes for Linux v4.2-rc4
These fixes are all for the AMD IOMMU driver:
* A regression with HSA caused by the conversion of the driver to
default domains. The fixes make sure that an HSA device can
still be attached to an IOMMUv2 domain and that these domains
also allow non-IOMMUv2 capable devices.
* Fix iommu=pt mode which did not work because the dma_ops where
set to nommu_ops, which breaks devices that can only do 32bit
DMA.
* Fix an issue with non-PCI devices not working, because there
are no dma_ops for them. This issue was discovered recently as
new AMD x86 platforms have non-PCI devices too.
----------------------------------------------------------------
Joerg Roedel (6):
iommu/amd: Use iommu_attach_group()
iommu/amd: Use iommu core for passthrough mode
iommu/amd: Allow non-IOMMUv2 devices in IOMMUv2 domains
iommu/amd: Use swiotlb in passthrough mode
iommu/amd: Set global dma_ops if swiotlb is disabled
iommu/amd: Allow non-ATS devices in IOMMUv2 domains
