Get to know SMP on x86 systems better

an idea by alix82

Project Description

In order to learn how operating systems work on a x86 chip, I had written (long ago) a toy OS based on code found on osdev wiki [1]. It allowed me to understand the interaction between the OS and the x86 hardware, and to some extent how the OS handles userspace (I used newlib for some userspace programs). The single-processor OS code later served me well as a base for a course about operating systems I taught at the university.

x86 instructions decoder

a project by bpetkov

This is the tool I've been working on since HW11 and it needs more work. Actually, there's always something which could be done on it. It is basically an x86 instruction decoder with special emphasis on the kernel and decoding interesting pieces of it in order to help in the development of low-level patching techniques, among others. git repo: https://gitlab.suse.de/bp/x86d

Create tool to analyze supportconfig to spot common SUSE Manager / Uyuni issues

an invention by cbosdonnat

Project Description

A supportconfig provides a lot of files and data from the system, but it is often hard to spot the real issue in it. The idea of this project is to get machine-readable output for the supportconfig data and analyze them.

consolidate mm debugging tools and package them

a project by mhocko

Project Description

Different people use different ad-hoc tools to debug Linux kernel MM (memory management) related issues. I have couple of those myself. They fall into two main categories. One set for proper data collection and the other for some high level analysis. Our customers would benefit from the former and we (L3 labs from the later). Having them in a single package sounds quite reasonable to me.
