Linux Kernel Fastboot on the Way

Linux Kernel Fastboot on the Way

Explore Linux kernel fastboot optimization techniques in this 48-minute conference talk from the Linux Plumbers Conference. Discover how to reduce kernel boot time from 3000ms to 300ms through various optimizations, including enabling asynchronous device driver probing, implementing deferred memory initialization, optimizing rootfs mounting, and more. Learn about potential future optimization points, such as maximizing multi-core usage, reducing SMP initialization costs, and parallelizing device enumeration. Gain insights into profiling and analysis tools, and understand the importance of balancing universality and performance in kernel modules and configurations.
