CE Linux Forum Bootup-time WG

• OLS paper (Tim Bird): “Methods to Improve Bootup Time in Linux”

• Kernel XIP, “partial XIP” (hotspots in RAM)

• kernel init: reduced probing; configuration cache

• Concurrent init of some subsystems

• Fast shutdown & resume (ties to Power Mgt.)

• Timing instrumentation

• Userspace startup time reduction (scripts, app. Pre-loading, pre-linking, app. XIP)

• Now sending some patches for kernel merging
