This prevents DMA from working. By providing the address space extents ppb(4) will automatically configure the bridge and set the bit.

Add support for the XIVE interrupt controller found on POWER9 CPUs. 2020-06-13T22:58:42Z kettenis kettenis@openbsd.org 2020-06-13T22:58:42Z urn:sha1:1af8fcf97b3b100709d0e932f7915e9a88dbb517 Allocate MSIs from the range provided by the device tree and bind them 2020-06-10T19:02:41Z kettenis kettenis@openbsd.org 2020-06-10T19:02:41Z urn:sha1:fbe807609c61870036576f06144597ab9f41e02b to a PE.
