Hi Mark, `hope we talk about the same context: The 1GB DMA range fix from Rob in https://reviews.freebsd.org/D26344 = <https://reviews.freebsd.org/D26344>; has NOTHING to do with UEFI/ACPI. It addresses the pcie-driver for fdt(u-boot). While there is probably some inheritances in the USB/pcie-chain: pcie is NOT exposed to the OS by rpi4Uefi-dev. Regards Klaus
