[opensuse-kernel] Build status is 'broken' for Build Service > Projects > Kernel:HEAD > kernel-vanilla

Hello, Build status is 'broken' for Build Service > Projects > Kernel:HEAD > kernel-vanilla See https://build.opensuse.org/package/show?package=kernel-vanilla&project=Kern… Perhaps a refresh to 2.6.36 is needed from the 2.6.36-rc8 is needed as well. Another question I have is: Can the process be automated so the current kernel mainline dragged in and build all the flavours against them eg vanilla, default... with minimal manual intervention ?.

[opensuse-kernel] /dev/root?
by Stefan Seyfried 25 Oct '10

Hi, simple question: who creates the /dev/root symlink? I'm pretty sure it's udev, but I could not find a rule for it on current FACTORY, so I'm asking here ;-) Thanks, -- Stefan Seyfried "Any ideas, John?"

[opensuse-kernel] TSC question for kernel developers
by Stefan Seyfried 15 Oct '10

15 Oct '10

Hi I know it's slightly offtopic, but I guess people here might know the answer ;-) On a modern CPU, with constant_tsc feature, how well synchronized are the TSCs when synchronized on bootup by the linux kernel? And do they stay like that, or do they drift? Thanks, Stefan -- Stefan Seyfried "Any ideas, John?"

[opensuse-kernel] How do I automate setting .config entries to "n"
by doiggl＠velocitynet.com.au 13 Oct '10

13 Oct '10

Hello, I get this abort message such as this example when compiling a package which involves a kernel. and the .config file. It always ends in 'aborted' at the end like this. "Texas Instruments ADS7871 A/D converter (SENSORS_ADS7871) [N/m/y/?] (NEW) aborted!" or "Compile Remote Controller keymap modules (RC_MAP) [M/n/?] (NEW) aborted!" It falls over on a diferrent line in the .config each time I submit a rebuild. This is a slow process doing one item at a time. Question. Is is possible to automatically set it so that (NEW) entries are set and stored in the .config like this CONFIG_{itemname}=n Thanks Glenn - So far its been a case of append the value to the .config eg CONFIG_RC_MAP=n - Then submit the build again, wait and encocounter the error on another .config entry. Here is a small list I struck so far. I added them in one at a time to the .config and submit another build. Its a slow process. CONFIG_CROSS_COMPILE="" CONFIG_COMPACTION=n CONFIG_ACPI_HED=n CONFIG_MFD_WM8994=n CONFIG_PCCARD_NONSTATIC=n CONFIG_ACPI_APEI=n CONFIG_INTEL_IDLE=n CONFIG_PCI_CNB20LE_QUIRK=n CONFIG_IP_MROUTE_MULTIPLE_TABLES=n CONFIG_NETFILTER_XT_TARGET_TEE=n CONFIG_NET_SCTPPROBE=n -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] kernel-debuginfo packages for Open Suse 11.3
by Alok Kataria 04 Oct '10

04 Oct '10

Hi, I am looking for the debuginfo packages for the open suse11.3 kernel, specifically the 2.6.34-12-desktop kernel. The kotd site has debuginfo packages for the KOTD at http://ftp.suse.com/pub/projects/kernel/kotd/openSUSE-11.3/x86_64/ is there a similar repository where the debuginfo package exists for all the released kernels ? I have a crash compliant core file for a panic with the opensuse 11.3 desktop kernel and was trying to use the crash utility to debug this. Please note that the vmlinux file that is available from the kernel-desktop-2.6.34-12.3.x86_64 rpm is not useful as it lack debug symbols.
