Hi,
Is there anyway to restrict the returned bus address(dma address) from dma_poll_alloc to < 4GB ? The function returns a dma address(of type dma_addr_t). Is there anyway I can ensure to restrict it to < 4B address. I guess we can do that in pci_alloc_consistent as by default it returns 32bit address.
with regards, Anil
