Hey, I've a problem with pci_alloc_consistent with Kernel 2.6.5 and memory >= 4GB on a x86_64 machine. The device can't use the dma_addr which I retrieve from pci_alloc_consistent. But if the machine has less then 4GB it works fine.
How can I prove that the adress I get from pci_alloc_consistent is dma compatible? Should pci_alloc_consistent not be used in environments before CONFIG_ZONE_DMA32? Is there a better way to get dma compatible memory since 2.6.1 (except using kmalloc and GFP_DMA, cause just below 16MB is not enough memory)? I'm very appreciative for any answer / help.
