==Linux Kernel==

{|cellspacing="0" border="1" width="70%"
|Name||Linux kernel
|-
|Purpose||The function of the kernel code is to provide all the basic services and hardware interfaces of the Linux operating system for the underlying programs. The kernel also passes the control to the chosen user space program (usually /sbin/init) after initializing its own structures and drivers. When the kernel starts up, it checks a lot of the available subsystems and initializes everything according to the kernel configuration chosen at compile time. Some subsystems will be left uninitialized by the boot loader, for example, the display subsystem.
|-
|Responsibilities||The operating system kernel

|Notes||Maemo specific functionality is in OMAP3 & Rover HW specific code. OMAP3 support is developed, generally speaking, in the linux-omap tree, from which code is pulled into Maemo kernel.
