§Initcall System
The initcall module manages the kernel’s initialization sequence by providing a structured way to execute initialization functions at different stages of boot.
§Submodules
early: Initialization functions that need to run early in the boot processdriver: Driver initialization routineslate: Initialization functions that should run late in the boot process
§Initcall Mechanism
The initcall system works by collecting function pointers between special linker
sections (__INITCALL_START and __INITCALL_END). Each function pointer
represents an initialization function that needs to be called during boot.
The initcall_task() function iterates through these function pointers and
executes each initialization routine in sequence, providing progress updates
to the console. After all initialization routines have been executed, the
processor enters an idle state.
