The Linux kernel requires that device drivers use the DMA remapping APIs to make physical memory accessible to devices, even when no remapping hardware is present. The NVIDIA Linux driver generally adheres to this requirement, except when it detects that the remapping is implemented using the SWIOTLB, which is not supported by the NVIDIA Linux driver. When the NVIDIA Linux driver detects that the SWIOTLB is in use, it will instead calculate the correct bus address needed to access a physical allocation instead of calling the kernel DMA remapping APIs to do so, as SWIOTLB space is very limited and exhaustion can result in a kernel panic.
