Dear Dennis, Marcus, & Greg, Thank you very much for kind help and advises. Finally I succeed to compile my "own style" Kernel 2.6.30.5 for SuSE 11.1. I did a "hybrid" trick of .config that use my favorite setting and the CPU section I pick from OpenSuSE stock setting. It runs as I expected.

[opensuse-kernel] Using Multicore with 2.6.30.5 OpenSuSE 11.1
by Wong 07 Sep '09

07 Sep '09

Dear List, I want to compile kernel 2.6.30.5 in openSuSE 11.1 to be able to use multicore of Intel Q8200. Here is my options: CONFIG_SMP=y CONFIG_MCORE2=y CONFIG_NR_CPUS=4 CONFIG_SCHED_SMT=y CONFIG_SCHED_MC=y CONFIG_PREEMPT_NONE=y **** make make modules_install make install **** But kernel seems did not recognize the setting I choose. Need advise what wrong I made. Thank you so much for your help Rgds, Wong -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

Hi, this seemingly illogical choice in Kernel:/HEAD/kernel-source-rt.src.rpm's config/*/* is puzzling, or just wrong. $ diff -dpru config/i386/{default,pae} (some happens on config/{i386,x86_64}/default) -CONFIG_X86_MSR=m -CONFIG_X86_CPUID=m +CONFIG_X86_MSR=y +CONFIG_X86_CPUID=y -CONFIG_IPV6=m +CONFIG_IPV6=y -CONFIG_LIB80211=m +CONFIG_LIB80211=y -CONFIG_ATA=m +CONFIG_ATA=y Just what is the purpose of doing that for the PAE/x64 config? It's like all but the i386-default config is horked. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] guards definitions

The guard expression logic seems to be rather blunt, or how does one express if (i386 && (syms || !foo)) that/config if (i386 && (syms || foo)) that/other/config in guards logic? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Nehalem kernel NUMA bug
by Кузьминский Михаил 05 Sep '09

05 Sep '09

I've dual E5520 server w/Supermicro X8DTI mobo (last June 2009 1.0c bios version). Default OpenSuSE 11.1 x86-64 kernel (2.6.27.7-9) gives an error in /sys/devices/system/node directory - there is node0 and node2 subdirectories instead of node0 and node1 (smt is turned off). As a result numactl tools don't work. I don't find the message about this error in SuSE bugzilla "database". This Nehalem/NUMA error is also known (AFAIK) for 2.6.29-6 default OpenSuSE kernel, and also in FC11 kernel 2.6.29, and in some CentOS 2.6 kernel; but there are kernels w/o this error :-) Is there some updated OpenSuSE 11.1 kernels w/o this error ? Or may be some OpenSuSE 11.2 kernels ?

A netbook without wifi is a pretty dumb thing...

[opensuse-kernel] Thinkpad Brightness Control
by Anshul Jain 14 Aug '09

14 Aug '09

Hi, I have a backport 2.6.27.x custom kernel installed on my 11.0 system, running KDE 4.3. I've noticed that the Thinkpad (mine's R61/R61i) brightness control does not work through the keypad. I can change it through the Powerdevil battery manager. I have the right options put in for brightness control in /etc/modprobe.d/thinkpad_acpi.
