start_kernel()
start_kernel()
performs most of the kernel setup:
start_kernel()
also prints (
pr_notice()
) the value of
linux_banner
(defined in
init/version.c
and
init/version-timestamp.c
).
At least in my current Linux environment, this is the first message visible to dmesg
.
The last function that start_kernel
calls is arch_call_rest_init()
which in turn calls rest_init()
which apparently does not return.
do_basic_setup()
This function is called when the machine is initialized and the CPU subsystem is started.
None of the devices have been touched at this moment.
