John Baldwin - Multiple Passes of the FreeBSD Device Tree
Multiple Passes of the FreeBSD Device Tree The existing device driver framework in FreeBSD works fairly well for many tasks. However, there are a few problems that are not easily solved with the current design. These problems include having "real" device drivers for low-level hardware such as clocks and interrupt controllers, proper resource discovery and management, and allowing most drivers to always probe and attach in an environment where interrupts are enabled. I propose extending the device driver framework to support multiple passes over the device tree during boot. This would allow certain classes of drivers to be attached earlier and perform boot-time setup before other drivers are probed and attached. This in turn can be used to develop solutions to the earlier list of problems.

John Baldwin - Introduction to Debugging the FreeBSD Kernel
Introduction to Debugging the FreeBSD Kernel Just like every other piece of software, the FreeBSD kernel has bugs. Debugging a kernel is a bit different from debugging a userland program as there is nothing underneath the kernel to provide debugging facilities such as ptrace() or procfs. This paper will give a brief overview of some of the tools available for investigating bugs in the FreeBSD kernel. It will cover the in-kernel debugger DDB and the external debugger kgdb which is used to perform post-mortem analysis on kernel crash dumps. Introduction to Debugging the FreeBSD Kernel Basic crash messages, what a crash looks like typical panic() invocation page fault example "live" debugging with DDB stack traces ps deadlock examples show lockchain show sleepchain Adding new DDB commands KGDB inspecting processes and threads working with kernel modules using scripts to extend examining crashdumps using utilities ps, netstat, etc. debugging strategies kernel crashes system hangs
