Basically, you want to add hot-plug memory and enable swiotlb, right? We can't start swiotlb reliably after a system starts. See dma32_reserve_boatmen() and dma32_free_bootmem(). What we do is reserving huge memory in DMA32 zone for swiotlb and releasing it if we find that we don't need swiotlb. We can't find enough memory for swiotlb in dma32 after a system starts. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
