Hello, Mitchell. There is no problem with this patch. This patch only controls the MMIO size for the aperture of the GPU BARs. Try adding a pxb-pcie for each numa node, attach a pcie-root-port to those root complexes, and then add GPUs to the root ports with or without additional switches. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
