Description:

The kernel package contains the Linux kernel (vmlinuz), the core of your
Mandriva Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc. This kernel is compiled for laptop use, targeting
users that wants prolonged battery life. If you want to sacrifice
battery life for performance / responsiveness, you better use the
kernel-desktop.
It supports single or multiple i686 processor(s)/core(s) and less than
4GB RAM, using HZ_300 instead of HZ_1000 as a compromise to save
battery, no preempt, CFS cpu scheduler, cfq i/o scheduler and some other
laptop-specific optimizations.
This kernel relies on in-kernel smp alternatives to switch between up & smp
mode depending on detected hardware. To force the kernel to boot in single
processor mode, use the "nosmp" boot parameter.
