[SOLVED] Laptop vs desktop kernel

Postby zugunder » Sep 16th, '11, 20:41

Hi,

It happened that I occasionally bumped into a package with kernel-laptop-tmb in Mageia repos. As far as I remember, there was no such thing as a separate laptop-optimized kernel for Mandriva, so I am kind of intrigued...
Sure, I installed it but of course after a couple of hours of usual activity can't see any differences compared to a desktop kernel, which is understandable.
Could anyone (a developer or maintainer) describe the difference between these two kernels in a couple of words - just to know where to look for laptop-optimized features (if there are any)?

Thank you.

There is no kernel-laptop-whatsoever package for Mageia ...
It's kernel-tmb-laptop. The most important features can be seen from the descripton of the package:
[doktor5000@mageia1 ~]$ urpmf --description kernel-tmb-laptop-2.6.38.7-1.mga
kernel-tmb-laptop-2.6.38.7-1.mga:
The kernel package contains the Linux kernel (vmlinuz), the core of your
Mageia.Org 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, single or
multiple x86_64 processor(s)/core(s), using HZ_250 to save battery,
voluntary preempt, BFS cpu scheduler, cfq i/o scheduler and some other
laptop-specific optimizations. If you want to sacrifice battery life for
performance, you better use the kernel-tmb-desktop.
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.
NOTE! This kernel also uses TuxOnIce by default.

Sorry, did not notice that... my fault.
Thank you.
