Hi all,
This is version four of the patches I previously posted here:
v1: https://lore.kernel.org/lkml/20191030145112.19738-1-w...@kernel.org/
v2: https://lore.kernel.org/lkml/20191108151608.20932-1-w...@kernel.org
v3: https://lore.kernel.org/lkml/20191121114918.2293-1-w...@kernel.org
Changes since v3 include:
* Based on v5.5-rc1
* ACPI/IORT support (thanks to Ard)
* Export pci_{enable,disable}_ats() (thanks to Greg)
* Added review tags
Since it looks like not much has changed since v3, and I even tested
removal of smmu-v3.ko [0] - this should be ok for the series:
Tested-by: John Garry <john.ga...@huawei.com> # smmu v3
[0]
https://lore.kernel.org/linux-iommu/c8eb97b1-dab5-cc25-7669-2819f64a8...@huawei.com/
I tested this on AMD Seattle by loading arm-smmu-mod.ko from the initrd.
Cheers,
Will
