I build the 'HelloWorld' and 'Httpd',there are two question :
(1)I found the kernel file size is approximately 9M， I view the elf file info by 'nm' command, there are many content I will not use.SO,how I exclude them in my kernel?
(2)In runing the qemu for this kernel,I use 256M memory, if my kernel only for some simple function,can I reduce the memory?how much memory I must provide?
