Question regarding pci_alloc_consitent() and __get_free_pages
Hi, I have a question regarding the pci_alloc_consistent() function. Will this function allocate pages that are physical contiguous ? i.e if I call this function with a size argument of 32KByte will that be 8 consecutive pages in memory on i386 architecture (4 pages on alpha). In general, will __get_free_pages(GFP_ATOMIC, order) always return physical contiguous memory ?
