Hello all:
I installed Gentoo using the LiveCD I downloaded for x86. I'm using IBM T30 which comes with Pentium 4 and an ATI card, RAM is 768.
When I was trying to get the xfree-drm to compile and load the modules, I had several errors. I found a post in the forums that said the error was because the processor was not 486 or higher. So I went to my .config and listed the processor type and realized it was set to 386.
I thought it was stange. I thought that during the installation genkernel would find and select my P4, but it did not do so. So I recompiled the kernel now selecting P4 and xfree-drm worked OK. Did genkernel select 386 processor because it was the default "x86" type?
This is just the beginning of my .config, the other things I changed were the Toshiba laptop support which was enabled by default! Did I do well, wrong? Are there other things I should watch over that could have been uncorrectly set? Or was everything OK and I'm doing it wrong?

Well, just for the record...
When I posted the above message I realized I was using the LiveCD for x86, I did not notice there was an "optimized" one for Pentium 4 just in another directory in Gentoo servers.
During the weekend I downloaded that CD which was supposed to be for P4 and reinstalled everything, using again stage 3. I thought this time I would not miss my processor type, but I was very much surprised to see that the .config file in /usr/src/gentoo still had the 386 option on, not any higher number!!! The configuration file was the same as that for x86.
That was with the 2.4.20-gentoo-r5 default sources. After "emerge sync" I got the 2.4.20-gentoo-r7 ones and right away started to recompile. Using genkernel --config I noticed again that it picked the 386 processor along with all sound/video drivers (not just the ones I needed).
I decided to do it myself and forget about genkernel. I typed
| Code: |
make mrproper
make oldconfig
make menuconfig
|
and was happy to see that just that 'oldconfig' found my radeon, AC97 sound driver, etc and even picked PentiumIII (not P4???). So I trusted the defaults which seemed to be pretty much OK and continued installation. Many other things were missing like support for reiserfs, fat, etc, which I just included into the kernel itself after somehow careful checking.
When I rebooted, there was a warning saying that Gentoo used DEVFS and that I did not compile it. However I booted OK, no kernel panic or else.
I went back to menuconfig and looked for DEVFS, but it did not appear in the menu (graphical menu). In the .config there was just
| Code: |
grep DEVFS .config
# CONFIG_DEVFS_FS is not set
# CONFIG_DEVFS_MOUNT is not set
# CONFIG_DEVFS_DEBUG is not set
|
I thought of changing it by hand (i.e. editing .config myself) so I wrote
and continue to make dep, but compilation failed!!!
When I used menuconfig and the .config from 2.4.20-gentoo-r5 I could find DEVFS right from the graphical menu under File systems. However, when I used menuconfig with the .config I obtained from "make oldconfig" DEVFS was missing. The graphical menu seemed much different in both cases also.
So I guess I wasted my time all over the weekend trying to "optimize" my system. I went back to the old 2.4.20-gentoo-r5 default configuration file, copied it to 2.4.20-gentoo-r7 directory and just changed the 386 for pentium 4 processor type. |
