Jan 11, 2016 · This adds support for runtime relocation of the kernel Image, by building it as a PIE (ET_DYN) executable and applying the dynamic relocations in the early boot code. On top of this, support for KASLR is implemented, based on entropy provided by the bootloader in register x1 at kernel entry.

This is possible only with the architectures which support a relocatable kernel. As of today, i386, x86_64, ppc64, ia64, arm and arm64 architectures support relocatable kernel. Building a relocatable kernel is advantageous from the point of view that one does not have to …

Relocatable kernel support for x86. This feature (enabled with CONFIG_RELOCATABLE) isn't very noticeable for end-users but it's quite interesting from a kernel POV. Until now, it was a requirement that a i386 kernel was loaded at a fixed memory address in order to work, loading it in a different place wouldn't work. ... KernelNewbies: Linux_2_6 ...

1) Enabling CONFIG_RELOCATABLE will make it very easy to configure kdump. 2) We have had need to use 3rd party drivers in the rt kernel for various devices, it made it possible to build those drivers for just the rt kernel, rather than both the rt kernel and the stock kernel. 3) Getting CONFIG_RELOCATABLE enabled will get it some testing!

The kernel command line can be located anywhere between the end of the setup heap and 0xA0000; it does not have to be located in the same 64K segment as the real-mode code itself. Fill in this field even if your boot loader does not support a command line, in which case you can point this to an empty string (or better yet, to the string “auto
