This presentation shows the process I went through to revitalize shared logging between the bootloader and the kernel. Currently, the bootloader log and the kernel log are independent from one another, which complicates the post-mortem log analysis process. At one time, these logs could be shared, which greatly enhanced the debugging process on embedded systems. During the talk, I quickly cover the history of the shared logging feature and changes in the internal kernel logging structures. Next, I discuss the some of the challenges encountered and iterative steps taken to get this feature working with the new kernel structures and in a more generalized way. Finally, I highlight remaining challenges that are left to be worked out and I conclude with a quick, live demonstration of the feature.
