Subject: Xeon processor support

Hello.

I have a RH7.3-based system with recompiled original 2.4.20 kernel runing on
dual 2.4GHz Xeon machine.

I'd like to know if there is a dedicated Xeon support in 2.4.21-pre? kernels.

The thing is I'm trying to compile RTLinux for this machine, but it fails to
start. The main reason of this is wrong CPU type support in kernel.

I compiled 2.4.20 for Pentium 4, but new Xeons are a bit different. So is
there a dedicated Xeon support in 2.4.21-pre? kernels?



Thanks.


Artemio.

The new xeons work fine with 2.4.20. Issues with rtlinux should probably
be directed to fsmlabs or their respective mailing lists...

Outside that what issues are you seeing?

Well, they seem to have no idea what's wrong. One guy at rtlinux mailing list
had success building rtlinux-3.2-pre3 with 2.4.20 kernel on dual 2.4GHz Xeon
machine. I have the same rtlinux-3.2-pre3 with 2.4.20 kernel on dual 2.4GHz
Xeon machine, but rtlinux hangs it when I start it. That guy gave me his
config but I didn't have any success anyway.

However, I have built the same 2.4.20/3.2-pre3 on PIII boxes and rtlinux runs
perfectly.

No issues.
I just know that Intel Xeon and Intel Pentium 4 Xeon are different things,
that's why I was asking - there is only a "Pentium 4" option in kernel
config.


Thanks for reply.
