Hi,
Near the end of kernel startup, there is a message 'Freeing init memory ..'. This process on embedded system takes several seconds. After searched kernel source, however, I cannot find the same literal text in all the .c files. rgrep 'Freeing' . on kernell source give me a lot of output. I believe you're looking on arm for that one: arch/arm/mm/init.c: printk(KERN_INFO "Freeing %s memory: %dK\n", s, size);
Yes, thank you very much! Now I want to disable the 'Freeing' behavior to reduce boot time, is there a kernel config or cmdline option? I am not sure if I can disable CONFIG_HIGHMEM to archive this purpose.
So, I want to know, who was printing this message and
how can I disable the behavior to save some boot time since I don't care losting of several hundreds kilo bytes of memory.
Thanks in advance. woody
