[opensuse-kernel] Keep 3.11.y kernel for openSUSE 13.1 updates?
by Takashi Iwai 12 Sep '14

12 Sep '14

Hi, Since 3.11.y maintenance was discontinued by Greg, Ubuntu took over it. It made me wonder: are we willing to continue 3.11.y for openSUSE 13.1 updates, just relying on Ubuntu? Or, can we just move on 3.12.y? Takashi -- 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_USB_SERIAL_WISHBONE in config/armv7hl/exynos
by Jean Delvare 29 Apr '14

29 Apr '14

Hi Alex, In: commit 957e65cd70e5666dfef341505d4115f29a7f56d0 Date: Wed Sep 25 16:25:49 2013 +0200 ARM: Update config files: Use lpae for multiarch, exynos for LPAE exynos5 you disabled CONFIG_USB_SERIAL_WISHBONE in config/armv7hl/exynos. Was there any reason for that? All other configuration files have it enabled. On the same topic, arm config files currently have all USB-to-serial drivers enabled except USB_SERIAL_MXUPORT and USB_SERIAL_QT2. There doesn't seem to be any reason for that except that these drivers are recent. Both are enabled on all other architectures. I would like to enable them on arm too for the sake for consistency.

Commit b0b49f2673f (x86, vdso: Remove compat vdso support) removed the FIX_VDSO macro defining the vdso area. This patch updates it to use the vdso pointer and size to define the area instead.

Jan - Can you take a quick look at this? I don't have any 32-bit x86 machines to test with (or more accurately, I don't really want to have a 32-bit install *just* to test this.)

[opensuse-kernel] Modularize PS/2 driver for Xen/EC2
by Davy Kager 24 Apr '14

24 Apr '14

Hi, I've been using openSUSE as my private-server-distro of choice for a few years now (so apologies in advance for being blissfully ignorant of the inner workings of these systems). Since it's a Xen guest I'm using Kernel:stable/kernel-xen. Before that I used the kernel tied to the current openSUSE release. So far so good. BUT, on boot I'd always see the I8042 driver taking some time to detect hardware, only to throw an error telling me it couldn't: [ 1.268512] i8042: No controller found This makes sense, I'm running headless. There didn't seem to be a readily available solution to this problem, so I let it be. Now it turns out that folks at Arch Linux got annoyed by the same thing and pushed a few patches to upstream[0]. The final realization was with kernel 3.13[1]. Would it be possible to do the same in openSUSE? In particular: CONFIG_SERIO=m CONFIG_SERIO_I8042=m CONFIG_SERIO_LIBPS2=m # not entirely sure about this one CONFIG_INPUT_MOUSEDEV=m As far as I can tell this should be reasonably safe on Xen, even safer on kernel-ec2. It might also be time to do this for the -default and -desktop kernels. I don't have nearly enough experience with Linux to know the exact impact that would have. Would be nice to bypass this step during boot on boxes `in the cloud', though. Thanks!
