A Pragmatic Guide to Boot-Time Optimization
Explore a pragmatic approach to boot-time optimization in this 40-minute conference talk by Chris Simmonds, a consultant for the Linux Foundation. Learn graded techniques to reduce boot time, starting with simple adjustments to the init sequence and progressing to advanced methods like U-Boot falcon mode. Discover how to make and maintain changes using standard configuration techniques, and observe the impact of each optimization on a typical embedded dev board. Gain insights into measuring boot time, optimizing user-space and kernel boot processes, and streamlining bootloader operations. Benefit from Simmonds' extensive experience in open-source embedded systems as he guides you through practical steps to achieve faster device boot times while considering long-term maintainability.
