Anyone know of a Linux kernel optimized for Intel Pentium M?

post #1 of 23
Thread Starter 
Are there any out there that have been released? Optimized for Pentium M/Dothan architecture, up to SSE2. I think I have seen one before, it's name started with the letter Z, but it is no longer available.

There is Con Kolivas' patched kernel it is kernel26-ck-pentm

Here is a link from the arch wiki but should be the same with other distros

Of course, you could (nay, should!) compile it yourself

I've never complied a kernel... I wouldn't even know where to start. Got a guide for this?

That is my situation, it seems rather complicated and time consuming on my end.

I'm looking at Kernel26-ck, quick-bookmarked it for later.

guys, compiling a kernel is way easy. Especially if you are doing it for Arch linux, it's practically set up for you. All you really need to know is what your CPU can or can not do, there are very few options that directly affect the kernel performance but the ones that do are really easy to figure out.

It's not difficult on any distro, it's just a different set of instructions. It's a pretty well documented process, and it's only as complicated as you wanna make it You can spend hours and hours tinking with the config, enabling (but mostly disabling) different options, then recompiliing to see if it all still works, lol.

But really, just compile your default kernel from your distro with "march=native -O2 -fomit-frame-pointer -pipe" CFLAGS, and it'll be optimised for your CPU. It'll still contain the garbage you don't need, like support for other CPUs, but the code will execute in a way that optimised for your rig

I've found a decent article on how to do it without it taking hours and hours and I'm preparing to compile a kernel myself using chemicalfan's flags. Question is, how long does the compile actually take? A couple hours? I can leave it overnight but I'm worried about things such as laptop heat levels

EDIT: Does: "march=native -O2 -fomit-frame-pointer -pipe" go into "time fakeroot make-kpkg --initrd --append-to-version=-tweak kernel-image kernel-headers" where it says "-tweak" ???

It should take a couple of hours - you start by typing
Code:
export CFLAGS="-march=native -O2 -fomit-frame-pointer -pipe"
export MAKEOPTS="-j2"
export CXXFLAGS=$CFLAGS"
before you run the compile/make command. Does the article mention running "menu oldconfig" or something similar, to generate the config file (which the build using to actually configure the kernel)?

Took 3 hrs 35 minutes apparently.

I did not run make oldconfig, No, and I got this error. From this article it appears one person did not actually get the new kernel properly configured fixed the problem by running "menu oldconfig" first, will definitely try that. I apparently found another article that told you to edit the "makefile" file, but if I'm correct running those commands into the terminal does the same thing?

I'm also configuring a pre-emptive kernel, I'm assuming there's no problems with that?
