FW: [opensuse-kernel] Creating device nodes for kernel driver

Hi Greg > > > I wrote a kernel device driver for a special purpose PCI > > > framegrapper device which I maintain using a kmp rpm-package. > > Great, why not work to get it upstream into the main kernel.org repo so that all distros and users can get to it? Well, the current hardware is based on a prototype xilinx FPGA implementation and therefore cannot be bought by anyone sofar. --> very limited use to the generel public currently and I am guessing that the kernel.org people will refrain to accept a driver they cannot get hardware for. Otherwise I am very much willing to provide source (there is no special magic nor ip involved imho). In addition I want to get rid of the obvious flaws like the creation of device nodes from user space setup script before getting fried on lkml. This is actually the reason why I am asking on this list than on lkml. > > Sofar I am grep'ing /proc/devices for the major number during > > startup and create the device nodes at startup. > Ick, no, that's not good. Yes, this is what I was expecting. > > The documentation I found on the web and in > > /usr/src/linux/Documentations seems to be outdated, incomplete or > > contradicting. > It shouldn't be, have you read the book, Linux Device Drivers, 3rd > edition, that says how to do this? It's a bit out of date, but you will get the basic idea. I have the outdated 2nd edition to my disposal and soon discovered that it too much outdated for this purpose. > > Hint, use a misc device if you want an easy way to do this automatically from your driver. Thanks for the hint! It is appreciated. I will now firstly hunt down the 3rd edition of the book > Have a pointer to your source code anywhere? Do you want it via Email?

This is just too good not to be exploited in 12.1, fixes a very long standing annoyance since (7.1?) when Online Kernel update was introduced, IMO this ought to be the distro default. Thanks for the Lizard page to documenting it. So I've put in a feature request - "Preserve Running Kernel On Kernel Update by Default" https://features.opensuse.org/312647 Hopefully there'll be support for it, so this edit to /etc/zypp/zypp.conf becomes uncessary on almost every install. # multiversion = provides:multiversion(kernel) The latest/running worked for me so far using factory adding kernels from the Kernel Team HEAD & stable repos, if you want a guinea pig to try it on my Tumbleweed install, I'd be very happy to do so. I'll let you know if a Kernel:HEAD update causes anything odd :) Regards Rob -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] 3.0-rc7, pretty please?
by Stefan Seyfried 16 Jul '11

16 Jul '11

Hi, can we get 3.0-rc7 in Kernel:HEAD soon? Because rc6 without ca5c485f55d326d9a23e4badd05890148aa53f74 and friends is pretty bad on USB after resume... And since USB is no longer a module, I cannot just rebuild the driver with a fix... the joy of monolithic kernels! :-) Thanks, -- Stefan Seyfried "Dispatch war rocket Ajax to bring back his body!" -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] USB autosupend woes
by Cristian Rodríguez 15 Jul '11

15 Jul '11

Hi: I would like to enable usb autosuspend globally, however I cannot do so because my mouse autosuspends and requires a button to be pressed every few seconds to wake-up, is there any way to "blacklist" only the mouse device, or better adding a quirk in the kernel source code to tell it not to suspend at all ? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Btrfs oops in 11.4
by Greg Freemyer 12 Jul '11

12 Jul '11

All, I just had a btrfs oops with a default 11,4 kernel. I haven't even tried a update kernel yet since I wasn't sure anyone would care. Unless advised otherwise, my plan is to try the same test with a Tumbleweed kernel and open a bugzilla if and only if I get the oops there too.

[opensuse-kernel] Kernel:HEAD cleanup - changed URL
by Michal Marek 11 Jul '11

11 Jul '11

Hi, in order to reduce load on the buildservice, I changed the Kernel:HEAD project to only build for one repository, which should work on any recent distribution: http://download.opensuse.org/repositories/Kernel:/HEAD/standard/ . If you were using a different repository previously, please subscribe to this one. The old repositories will be deleted soon.

[opensuse-kernel] kernel-xen for Factory?
by Andreas Jaeger 07 Jul '11

07 Jul '11

currently installation-images does not build for factory due to a missing kernel-xen. Jan fixed this with his last commit but I still do not see kernel- xen in the obs Kernel:Head project. Could somebody investigate and submit a new kernel to factory, please?

[opensuse-kernel] Workshop on profiling, tracing, debugging both userspace and kernelspace for openSUSE conference

Kernel developers, I've seen some requests for a workshop (see $subject) for the openSUSE conference. Are there any volunteers? Details on how to submit a proposal: http://news.opensuse.org/2011/06/02/opensuse-conference-cfp-going-strong/ You can also submit other proposals that you like!

[opensuse-kernel] removing Xen 32-bit host support
by Jan Beulich 01 Jul '11

01 Jul '11

Just as we're in the process of doing for SLE11 SP2, we'd like to remove 32-bit host support in Xen (and hence kernel-xen) for 12.1. 32-bit guests will continue to be supported. Please speak up if you have reasons that should keep us from doing so.
