[opensuse-kernel] CONFIG_CC_STACKPROTECTOR
by richard -rw- weinberger 14 Dec '13

14 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] kernel-xen 3.9.2 leads to oops'es in domU xennet
by Eugene Istomin 24 Jun '13

Hello, yesterday i discovered regression in xen on 3.9.2 (http://lists.xen.org/archives/html/xen-devel/2013-05/msg01746.html) I use OBS for 3 years but i'm not familar with opensuse kernel patches submit process. Can you apply this patches to kernel-xen? 1) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id… 2) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id… 3) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id… 4) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id… 5) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id… -- Best regards, Eugene Istomin -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] aufs3
by Duncan Mac-Vicar P. 11 Jun '13

11 Jun '13

Hi guys, During Hackweek Flavio got Docker (http://www.docker.io) working on openSUSE (http://flavio.castelli.name/2013/04/12/docker-and-opensuse/) As it requires aufs3, right now the installation pulls a patched kernel from miska: https://build.opensuse.org/project/show?project=home%3A-miska-%3Aaufs Is there any position in the kernel team with respect to having aufs3 in the kernel itself? or, the required patches and build aufs3 as a separate package? (http://aufs.sourceforge.net/) On the other hand, for some reasons distros don't seem to like aufs: https://github.com/dotcloud/docker/issues/172#issuecomment-17321612 (Please CC me, I am not subscribed). -- Duncan Mac-Vicar P. - http://www.suse.com/ SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) Maxfeldstraße 5, 90409 Nürnberg, Germany -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Built-in kernel drivers
by Jean Delvare 06 Jun '13

06 Jun '13

Hi all, I recently noticed that driver ucb1400_gpio was built into all openSUSE kernels while most systems did not need it. Now that I fixed this specific issue, I decided to check if there were other drivers like that. I used the following script to test my running systems: #!/bin/sh find /sys/bus -path "*/drivers/*/uevent" | sed -e 's/\/sys\/bus\/$.*$\/uevent$/\1/' | sort > /tmp/drivers find /sys/bus -type l -path "*/drivers/*" | sed -e 's/\/sys\/bus\/$.*$\/[^/]*$/\1/' | sort -u > /tmp/drivers_with_devices diff -u /tmp/drivers_with_devices /tmp/drivers | grep '^+[^+]' | cut -c 2- OK, this is a somewhat crude heuristic but it seems to work. I ran this script on 3 different machines running openSUSE 12.2 or 12.3, and took the common results. This led me to the following driver list: acpi/drivers/ec acpi/drivers/hardware_error_device acpi/drivers/hpet hid/drivers/a4tech hid/drivers/belkin hid/drivers/cherry hid/drivers/chicony hid/drivers/cypress hid/drivers/dragonrise hid/drivers/ezkey hid/drivers/greenasia hid/drivers/gyration hid/drivers/kensington hid/drivers/kye hid/drivers/logitech hid/drivers/microsoft hid/drivers/monterey hid/drivers/ortek hid/drivers/pantherlord hid/drivers/petalynx hid/drivers/samsung hid/drivers/smartjoyplus hid/drivers/sony hid/drivers/sunplus hid/drivers/thrustmaster hid/drivers/topseed hid/drivers/twinhan hid/drivers/zeroplus i2c/drivers/dummy mdio_bus/drivers/Generic PHY pci/drivers/agpgart-sis pci/drivers/agpgart-via pci/drivers/ioapic pci/drivers/ohci_hcd pci/drivers/pci-stub pci/drivers/serial pci/drivers/tsi721 pci_express/drivers/aer pci_express/drivers/pcie_pme platform/drivers/dsa platform/drivers/ucb1400_gpio This is a rather long list, 41 drivers. While I am certain that there are false positives, either common hardware which I just happen to not have on any of my machines (most of pci and acpi), or drivers we may need very early (pci/serial?), or pseudo-drivers which are in fact part of their subsystem core (i2c/dummy, pci_express/aer, pcie_pme), it still seems to me that many of these should be modularized, to make our kernel smaller in size and faster to boot. More than half of the drivers are HID drivers. They are only built-in in 4 kernel flavors: i386/desktop, x86_64/desktop, ppc/default and ppc/vanilla. Jeff, Jiri, is this on purpose? If not, can I change all these to modular? Then we have mdio_bus/Generic PHY (what a driver name is that? <sigh>), pci/tsi721 and platform/dsa left. mdio_bus/Generic PHY is part of PHYLIB, I think we could build that as a module? It was accidentally made a bool in kernel v3.2-rc1 but was reverted to tristate in v3.2-rc5. Jeff, you made it build-in in commit 455827126, no objection to me making it a module again? pci/tsi721 is part of RapidIO. None of RapidIO support being built as modules. Which is a shame really, because I suspect most users don't need that and it isn't small - 165 kB on x86-64. This needs to be discussed with upstream. And finally platform/dsa is already dealt with in Factory.

[opensuse-kernel] New kernel flavour rpm
by Mariusz Fik 01 Jun '13

01 Jun '13

Hi, I'd like to create a new kernel flavour package with Con Kolivas patches[1] (including BFS) and BFQ IO scheduler[2]. As base I think kernel-vanilla may be a good start (no other patches, upstream .config). I see that every kernel flavour package links to kernel-sources which holds all .spec and .changes. There are many scripts in kernel-source and I'm not sure how they really work. How should I proceed with creating package, to minimize (avoid - is it possible?) breakage when kernel-source is updated? So far, I created subporject[3] and linked kernel-source from 12.3:Update. Then created kernel- ck with links to kernel-source. And what to do next?

[opensuse-kernel] Samsung NP300V5A -- no backlight brightness change
by Денис Купляков 15 May '13

15 May '13

Hello all! Fn + F2(down) and Fn + F3(up) don't change brightness level of backlight on my Samsung NP300V5A laptop. I have OpenSUSE 12.3 with bumblebee installed as described in Wiki ( Repo URL: Index of /repositories/home:/Overman79:/Laptop/openSUSE_12.3 ). There we no brightness change before installation of bumblebee (so I don't think it has influence) With no special setup, I can't lower brightness (screen is flickering), and have 3 entries under /sys/class/backlight: Code: acpi0_backlight acpi1_backlight intel_backlight Haven't tried to manipulate them through console. With acpi_backlight=vendor, I can't up brightness, and have 2 entries: Code: intel_backlight samsung Changing brightness with intel_backlight through console seems OK, but changing it with samsung don't work, I can set only 0 or 1 brightness level(same with Fn-##) Code: dmesg | grep samsung [ 16.423716] samsung_laptop: enabled workaround for brightness stepping quirk [ 16.424060] samsung_laptop: detected SABI interface: SwSmi@ I have solved problem for me, by deleting strange workaround from samsung-laptop.c and recompiling module. I think that it is a bug. I can see that we have some notebooks models hardcoded in module for quirk workaround (there is no my model). So I think that actual bug is inside code that determines whether workaround is needed or not (it is check_for_stepping_quirk(..) function)). Also I don't clearly understand what #ifdef CONFIG_ACPI do. But I have no samsung-laptop-acpi related messages in logs.
