Hi, We've developed a driver for an image acquisition card, which maps kernel alloc'ed buffers into user space vma's. We use alloc_page + remap_pfn_range in the driver mmap file_operation.
After looking at alloc_page_vma, I thought that it might be more appropiate than alloc_page in this context. However, if CONFIG_NUMA=y (x86_64), this function is not visible to modules. Is this limitation intentional? We alloc RAM in a page-by-page basis. Is vm_insert_page more appropiate than remap_pfn_range? Thanks a lot for your help.
