A couple kernel questions...


Somewhat inessential, but I just had some questions when compiling a new kernel. I had done this a while ago, on Slackware 10.1, but when I upgraded to 10.2 I reformatted the partition, so I did not have that one. Also, my first attempt at compiling a kernel was a bit shoddy, to say the least. After numerous attempts, I finally got my 2.6.14.5 kernel working fine, but I still have some questions.
1) Is it necessary to run make clean every time you recompile? I forgot to do this once, and I noticed that it compiled almost instantly. If I don't run make clean, will it be the same old kernel again, or will it only recompile the parts I changed? That would have saved a lot of time when I was repeatedly recompiling for things I had forgotten.
2) How do I get the Tux Logo to appear? This is just a matter of preference, but I did compile framebuffer support and the radeon framebuffer driver into the kernel and enabled logos, but I still don't get the Tux logo as it does in the default kernel from Slackware 10.2. I also prefer that way because it keeps the text smaller it seems, and makes it easier to read messages.
3) Do I need to reinstall the ATI Radeon drivers? It seems that after recompiling, all 3D accelerated programs are much slower, and I get around 70-80fps in glxgears. I guess it's obvious, but maybe it's something else, because I didn't need to reinstall my sound drivers like I did when I first installed Slackware.

This is a selective response to one bullet-item only.

You do not have to make clean if you are doing a simple recompile, as long as you know your system clock is correct. It will only recompile the parts that you have changed.

For the first compile of a fundamentally new kernel, I would do the following:
  • Make a backup copy (somewhere else) of your .config file. (That's the hidden file .. hidden, hence the initial "." .. which contains the configuration settings.)
  • mv .config foobar .. to keep the file out of harm's way.
  • make distclean .. to reset everything.
  • mv foobar .config .. to put the config-file back (observe the leading ".")
  • make
  • additional makes as required.

OK, thanks a lot, that really helps. 2.6 is so much faster than 2.4 in booting, it is almost scary. Now I can tinker away. Do you know anything about the logo thing?

Thanks, that's probably it. I'll try it out tomorrow. And I think I've resolved the graphics driver issue by reinstalling them.

RH 7.2 in ancient. Get a new distro. Not worth mucking with.

You probably need to update/install modules-init-tools
