Explore the intricacies of Linux Kernel Initcalls in this informative 31-minute conference talk presented by Mylène Josserand from Collabora. Delve into the purpose, distribution, and debugging of initcalls, and gain insights into their implementation through practical examples. Examine the expanded version of initcalls, understand level-initcalls ordering through Makefiles, and learn about initcall level ordering. Discover the role of linker scripts and the do_initcall_level function in the process. The talk also covers module initialization, including built-in and loadable modules, providing a comprehensive overview of this crucial aspect of Linux kernel development.
