IOVA address range

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Need a little IOVA/IOMMU help.

Is it correct that the IOVA address range for a device goes from
address 0x0 up to the dma-mask of the respective device?

Is it correct to assume that the base of the IOVA address space for a
device will always be zero (0x0)? Is there any reason to think that
this has changed in some newer iteration of the kernel, perhaps 5.10,
and that the base could be non-zero?

I realize an IOVA itself can be non-zero. I'm trying to verify what
the base address is of the IOVA space as a whole on a per device
