From 9b5a7f4a2a8dcda461f9c7a6671150f4a8a902e8 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Thu, 31 Mar 2022 10:57:28 -0700 Subject: x86/configs: Add x86 debugging Kconfig fragment plus docs The kernel has a wide variety of debugging options to help catch and squash bugs. However, new debugging is added all the time and the existing options can be hard to find. Add a Kconfig fragment with the debugging options which tip maintainers expect to be used to test contributions. This should make it easier for contributors to test their code and find issues before submission.
