Hi, everyone I wish to alloc physically contiguous memory in kernel mode. I used the __get_free_pages(gfp_mask, order) function, but it fails occasionary. I guess it is caused by memory fragmentation. My code is kernel driver module which cannot use bootmem allocation and its platform is x86_64. My server desktop has 20GB memory. I wish to know the method to allocate physically contiguous memory not failing by fragmentation.
Thanks in advance. Best Regards, J.Hwan Kim -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
