I will provide a hands on guide on dissecting and learning the Linux kernel . But I am busy with work and so forth and It may not be able to post in regular way. I however will not spoon feed and I will just be providing general guidelines. Also I will covering the linux kernel specific to the ia-32 platform .<\/p>\n
Download the newest linux kernel from www.kernel.org.make sure that you have newer version of gcc. To find out the current gcc version ,type If do not have ncurses library installed if present type For a qt based utility type for gtk based type if(kernel series is 2.4 ) Now finally build the kernel Thus your kernel is made.Installation of newer kernel is bootloader specific grub has a different way,lilo has a different way.But the basic idea is same.For older kernel\u2019s 2.2 vesrions etc we can put this kernel image directly into floppy for testing<\/p>\n After extracting and compiling the kernel code, it\u2019s time to peek at the different directories. The basic gcc inline assembly format is as follows<\/p>\n you can search the net in detail on how to use inline assembly with gcc.<\/p>\n In Part2 we will focus more on the x86 architecture<\/p>\n","protected":false},"excerpt":{"rendered":" I will provide a hands on guide on dissecting and learning the Linux kernel .
