kexec is a system call that enables you to load and boot into another
|
||
|
|
kernel from the currently running kernel. kexec performs the function
|
||
|
|
of the boot loader from within the kernel. The primary difference
|
||
|
|
between a standard system boot and a kexec boot is that the hardware
|
||
|
|
initialization normally performed by the BIOS or firmware (depending on
|
||
|
|
architecture) is not performed during a kexec boot. This has the effect
|
||
|
|
of reducing the time required for a reboot.
|
||
|
|
|
||
|
|
Make sure you have selected CONFIG_KEXEC=y when configuring the kernel.
|
||
|
|
The CONFIG_KEXEC option enables the kexec system call.
