For an electrical-engineering research project, I'm looking for a way to have a code of a simple test-program running on a PC, to operate on an entire single-core while having full access to cpu resources and the entire non-virtual address space.
No preemptions / threads etc. Just like in real-mode.
Real-mode however, is limited to 16-bit, while in this case, This is a modern PC and I need an access to the entire 64-bit address space.
So I'm looking for any distribution of linux / unix / any-os that boots directly into terminal and allowing nothing but a simple C program to run.
Or - a modern linux, that is already preconfigured for almost-nothing installed, and w/o any background processes / kernel-maintenance threads and so on..
Any ideas ?
Many thanks in advance !!!
