[opensuse-kernel] retiring UP no APIC patch for 10.3
by Andi Kleen 15 Aug '07

15 Aug '07

Hallo, Traditionally SUSE kernels disabled the APIC on UP or older systems. These patches always were a source of bugs unfortunately because being relatively intrusive and not in mainline. This was originally added because old kernels used to force APIC if the CPU supported it and often systems were not set up to handle that failed. But newer kernels never try to force APIC if the BIOS didn't allow it explicitely, which avoids most of the problems. Other distributions also seem to ship with this and it works for them. The APIC can be still disabled with nolapic (or noapic for only the IO-APIC) Currently the patch is not in for 10.3 and unless we get a lot of reports of broken old systems in Beta because of this I plan to not add it. It would be good if people could test their old systems with the Betas though. -Andi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Testing the Current Upstream Kernel
by Jan Blunck 15 Aug '07

15 Aug '07

Andrew Morton has spoken at different occasions about testing of the Linux kernel and asked users to test the current development version and report their findings. For our openSUSE releases we have in general a frozen version and add only fixes for bugs that are encountered during testing - but stay with the same version for the lifetime of a release. With our openSUSE Build Service we build a daily kernel, where we take nightly snapshots of the current upstream development kernel (Linus' kernel tree linux-2.6.git) without any patches (besides those we need for building a RPM). We do call this the vanilla kernel. It can be downloaded from: http://download.opensuse.org/repositories/Kernel:/Vanilla/SUSE_Factory/ To install and use the vanilla kernel you might need to update some of your user-space tools as well (like udev etc.). If you are running the latest openSUSE Developer Version (aka Factory) you should already have the correct version of tools installed. If you test the vanilla kernel, report any problems to the Linux kernel mailing list (for details check the FAQ at http://www.tux.org/lkml/) and not to the openSUSE bugzilla. If you want to report problems with the RPMs itself or have general questions about the Kernel:Vanilla project use the opensuse-kernel(a)opensuse.org mailing list.

[opensuse-kernel] Problems with x86-64 installation on Beta1
by Andreas Jaeger 14 Aug '07

14 Aug '07

We saw a lot of bug reports that people cannot install on x86-64 machines. Is there a common pattern? Could you look at the bugreports and tell us why Alpha7 worked for these reporters but Beta1 fails? What can be done? Bugs include the following: 299010 299575 299690 299663 287039 299340 299604 Thanks, Andreas -- Andreas Jaeger, Director Platform / openSUSE, aj(a)suse.de SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] opensuse 10.3 kernels

Does the default 32 bit kernel install on 10.3 have PAE enabled? If not can you enable PAE on a 32 bit install? Thanks, Stephen Shaw -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] nohz bad for powerconsumption ?
by Andreas Jaeger 03 Aug '07

03 Aug '07

I'm using the new default kernel (from kerneltest) with nohz enabled and noticed the following with powertop on an idle system: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PowerTOP version 1.7 (C) 2007 Intel Corporation Cn Avg residency (3s) P-states (frequencies) C0 (cpu running) ( 2.0%) C1 0.0ms ( 0.0%) 1400 Mhz 33.0% C2 7.4ms (48.8%) 1300 Mhz 0.0% C3 7.6ms (30.3%) 1200 Mhz 0.0% C4 4.7ms (18.9%) 600 Mhz 67.0% Wakeups-from-idle per second : 145.7 Power usage (ACPI estimate): 12.1W (0.9 hours) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Booting the same kernel with nohz=off, I get: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PowerTOP version 1.7 (C) 2007 Intel Corporation Cn Avg residency (10s) P-states (frequencies) C0 (cpu running) ( 5.4%) C1 0.0ms ( 0.0%) 1400 Mhz 0.0% C2 2.9ms (42.0%) 1300 Mhz 0.0% C3 3.3ms (14.2%) 1200 Mhz 0.0% C4 3.2ms (38.5%) 600 Mhz 100.0% Wakeups-from-idle per second : 307.5 Power usage (ACPI estimate): 10.5W (1.0 hours) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ So, for me the nohz kernel uses more power. This seems to be a result From running on an idle system with 33% on high power. Some information about the system: cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.40GHz stepping : 6 cpu MHz : 600.000 cache size : 2048 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe up est tm2 bogomips : 1197.25 clflush size : 64 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor ondemand Is this worth a bugreport? Anything else I should supply?

What do you > think? Although this fits more in the responsibilities of the kernel teamleads. Well, I don't think the kernel teamleads are maintaining this package, you are, right? Unless you don't want to do it, and in which case, the team leads can argue over it :) thanks, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] 2.6.23 kernel in OpenSUSE 10.3?
by Ildar Akhmetshin 01 Aug '07

01 Aug '07

Just curious if there are any plans on switching to 2.6.23 kernel for OpenSUSE 10.3? If it's too late to change the kernel, then maybe a -CFS or/and -SD patched flavors can be released through BuildService. I just think it'll be beneficial for an already great Linux distribution.
