[opensuse-kernel] CONFIG_CC_STACKPROTECTOR
by richard -rw- weinberger 13 Dec '13

13 Dec '13

Hi! I'm wondering why CONFIG_CC_STACKPROTECTOR is disabled on openSUSE. Debian and Fedora seem to enabled it per default. What's the deal? -- Thanks, //richard -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] CONFIG_SND_HDA_PREALLOC_SIZE too small
by Cristian Rodríguez 02 Apr '13

02 Apr '13

Hi: Is there a reason why CONFIG_SND_HDA_PREALLOC_SIZE is set to 1024 when the documentation says. "A larger buffer (e.g. 2048) is preferred for systems using PulseAudio. " .. plus all other distributions I have checked: fedora and arch 4096 mandriva 2048 gentoo 2048 is this an oversight or intended ? at least for kernel-desktop it looks like we want 4096 .. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] opensuse 12.3 xen-kernel happened i915 issue in Thinkpad x200
by Jun Hu 30 Mar '13

30 Mar '13

Hi Guys: I met a graphical video crad issue in my pc :Thinkpad x200 In the last months , I use Opensuse 12.2 userspace with kernel 3.7.3, desktop,default , xen flavors are ok. they can enter X window with i915 driver which kms supported. but now I upgrade to 12.3, I found kernel 3.7.10 desktop ,default kernel are ok ,with i915 kms supported. but kernel-xen-3.7.10 l boot ok and can't enter X window. when I add parameter "nomodeset" , can enter X window. wiredly , I use Opensuse 12.3 userspace with kernel-xen-3.7.3 ,when it boots to load i915 module , the screen shows black . of course if I add parameter "nomodeset", can enter X window. why do I need use xen-kernel in PC ? maybe you feel strange , because I want to study xen or kvm virtulization technology. I can't find any useful info in /var/log/messages. -- --------------------------- Suse Linux ,Best ! ---------------------------

[opensuse-kernel] UCB1400 support
by Jean Delvare 30 Mar '13

30 Mar '13

Hi all, Investigation reveals that the UCB1400 is only used on ARM OMAP machines: linux $ git grep '"ucb1400_core"' arch/arm/mach-pxa/balloon3.c: .name = "ucb1400_core", arch/arm/mach-pxa/cm-x2xx.c: .name = "ucb1400_core", arch/arm/mach-pxa/colibri-pxa270.c: .name = "ucb1400_core", arch/arm/mach-pxa/palmtc.c: .name = "ucb1400_core", arch/arm/mach-pxa/vpac270.c: .name = "ucb1400_core", drivers/mfd/ucb1400_core.c: .name = "ucb1400_core", This means that CONFIG_TOUCHSCREEN_UCB1400=m, CONFIG_GPIO_UCB1400=y and CONFIG_UCB1400_CORE=m are useless in non-ARM configuration files, and as I understand it, they could also be removed from armv5tel/versatile and armv7hl/exynos. I'm going to do that if there are no objections in the next few days. Also, investigation revealed that the gpio-ucb1400 driver is dead code at the moment, and given that it can't be built as a module, I would like to remove it not only in the Factory kernel but also in the 12.2, 12.3 and stable kernels (non-arm, at least.) If you disagree, speak up now. -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Increase Thinkpad fan speed
by Sankar P 29 Mar '13

29 Mar '13

Hi, I have a Thinkpad T400 where the machine overheats whenever I run openSUSE. The fan speed never increases even though the machine is too hot and shutsdown eventually. I googled and found http://www.thinkwiki.org/wiki/How_to_control_fan_speed Bu I could not get the thinkpad_acpi.conf file or the /proc/acpi/ibm/fan file. So what is the way to increase the fan speed in openSUSE ? -- Sankar P http://psankar.blogspot.com -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] kcmp --> Function not implemented
by Cristian Rodríguez 29 Mar '13

29 Mar '13

Hi: According to the manual the kcmp system call appeared in kernel 3.5 but SUSE kernels do not enable CONFIG_CHECKPOINT_RESTORE (kernel:head included) zgrep CHECKPOINT_RESTORE /proc/config.gz # CONFIG_CHECKPOINT_RESTORE is not set Is there a reason why it is disabled ? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Secure boot with self built kernel on openSUSE or SLES
by Thomas Renninger 12 Mar '13

12 Mar '13

Hi, I've seen the various module signing and other patches to make secure boot work. But I could not find some kind of quick guide how to sign a kernel and modules myself, install my own key or whatever is needed. If I have missed an already existing documentation, it would be great if someone can point me to it. Otherwise it would be nice to have a tiny thread explaining what tools are needed, etc.. Differences to SLES would be nice to know as well.
