hi list, i think, there is a bug in the latest factory-kernel 2.6.27.13-2 from http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/. at least the kernel source has a bug, i think. i tried to install latest nvidia-driver 180.22 on an opensuse11.1 x86_64 system. former kernel 2.6.27.12-1 had no problems with this. but this time, it was not possible to load nvidia kernel module. the installation-script stopped, and told me that the built kernel module can't be loaded. there were also warnings about missing symbols at compile time. this is the relevant part of dmesg-output when loading the driver: nvidia: Unknown symbol pv_mmu_ops nvidia: Unknown symbol pv_cpu_ops nvidia: Unknown symbol pv_irq_ops nvidia: Unknown symbol pv_lock_ops it seems, the above symbols are missing. this was not the case with 2.6.27.12-1. i had to downgrade kernel to latest available 2.6.27.7-9 from oss-repo. with this version building the nvidia driver also was no problem. right now i am writing this mail with this setup. there must have been some changes between 2.6.27.12-1 and 2.6.27.13-2 which have something to do with these missing symbols. does anybody know anything about this error? -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Please contact nvidia about their driver, there is nothing we can do about it due to their licensing decision. good luck, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

i don't think, the problem comes from the driver. because, i was able to build the same nvidia-driver with previous version of factory-kernel, without any problems. so there must be some changes in the factory-kernel causing the problems. something about the symbols symbol pv_mmu_ops, pv_cpu_ops, pv_irq_ops and pv_lock_ops. -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

hi list,

i think, there is a bug in the latest factory-kernel 2.6.27.13-2 from http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/.

at least the kernel source has a bug, i think.

i tried to install latest nvidia-driver 180.22 on an opensuse11.1 x86_64 system. former kernel 2.6.27.12-1 had no problems with this. but this time, it was not possible to load nvidia kernel module.

the installation-script stopped, and told me that the built kernel module can't be loaded.

there were also warnings about missing symbols at compile time.

this is the relevant part of dmesg-output when loading the driver: nvidia: Unknown symbol pv_mmu_ops nvidia: Unknown symbol pv_cpu_ops nvidia: Unknown symbol pv_irq_ops nvidia: Unknown symbol pv_lock_ops

it seems, the above symbols are missing.

this was not the case with 2.6.27.12-1.

i had to downgrade kernel to latest available 2.6.27.7-9 from oss-repo. with this version building the nvidia driver also was no problem. right now i am writing this mail with this setup.

there must have been some changes between 2.6.27.12-1 and 2.6.27.13-2 which have something to do with these missing symbols. Hmm , I'am running 2.6.27.13-HEAD_20090125010735_8d0b1ab5-default x86_64 from http://ftp.suse.com/pub/projects/kernel/kotd/HEAD/x86_64/ and I had no

Well, think of new options. How do you set them when running cloneconfig ? That .config is used by SUSE to build their binary kernels. So it should reflect such changes. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

when i do "make cloneconfig", then the .config is cloned from /proc/config.gz which comes from the kernel currently running the machine, which is the same kernel i am using the source from for building the nvidia-module. -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Basically it works so. I wonder what got broken on your setup, too. Anyway, check whether you have CONFIG_UNUSED_SYMBOLS=y. Without this option, the symbols needed for nvidia / frglx won't be exported to modules.

yes, me too. i always do it this way. it never failed in the past. and i did nothing special this time. installed new kernel with the following packages: kernel-default-base-2.6.27.13-2.1 kernel-default-extra-2.6.27.13-2.1 kernel-source-2.6.27.13-2.1 kernel-default-2.6.27.13-2.1 kernel-syms-2.6.27.13-2.1

kernel-syms is needed only when you build modules with all flavors. If you need to build one flavor, it's not needed at all. The file Module.symvers is contained in kernel-$FLAVOR-base.rpm, too.

kernel-syms is needed only when you build modules with all flavors. If you need to build one flavor, it's not needed at all. The file Module.symvers is contained in kernel-$FLAVOR-base.rpm, too.

thank you. ok, i noticed that just a few minutes ago. i found factory-kernel 2.6.27.11-2.1 on http://ftp.iasi.roedu.net/mirrors/opensuse.org/repositories/Kernel:/HEAD/ope... this kernel is a little older than latest 2.6.27.13-3.1. like with 2.6.27.12-1 from last week (not available any more) it was no problem building the nvidia-kernel module. i noticed one thing about .config file when i had installed 2.6.27.13-3: in /usr/src/linux-2.6.27.13-3 there was the file .config.running. when i did "make cloneconfig" i got the error/warning about setting some XFS related config-variable to "m" and the resulting .config was NOT the same as the .config.running. it looked this way: linux-2.6.27.13-3: -rw-r--r-- 1 root root 89700 Jan 27 10:40 .config -rw-r--r-- 1 root root 90134 Jan 27 10:36 .config.running and in the directory /usr/src/linux-2.6.27.13-3-obj/x86_64/default there was this .config: -rw-r--r-- 1 root root 89782 Jan 27 10:45 .config so THREE different .config-files. right now, with 2.6.27.11-2 installed, it looks like this in /usr/src/linux-2.6.27.11-2: -rw-r--r-- 1 root root 90123 Jan 27 11:01 .config -rw-r--r-- 1 root root 90123 Jan 27 11:01 .config.running and like this in /usr/src/linux-2.6.27.11-2-obj/x86_64/default: -rw-r--r-- 1 root root 90123 Jan 16 04:13 .config so, as you can see, ALL .config files are the same with kernel 2.6.27.11-2 which is working great with nvidia-kernel-module. and with 2.6.27.13-3 there are 3 different .config files... maybe this has something to do with the problem... -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

It seems that we recently disabled paravirt on default config. So pv_* don't exist any more. I guess it's a problem nvidia side, e.g. you are building with the old object refering to non-existing pv_*.

ok, understood. so either nvidia changes the pre-built module-part (AFAIK the nvidia-kernel-module consists of 2 parts, a pre-built part and a part that has to be made at install-time) or i have a kernel, with paravirt enabled, so that latest pre-built nvidia-kernel-module fits. right? this issue has to be fixed in any way, BEFORE this factory-kernel becomes some day the official next opensuse-kernel or the official update-kernel for opensuse11.1. if not, alle users working with proprietary nvidia-driver will habe black-screens...... :-( -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

This must be fixed by nvidia. Their driver is faulty.

You don't need pre-built stuff for nvidia module. The binary-only part of nvidia driver has nothing to do with paravirt, and the rest can be compiled from the source code.

It works on my machine. I just built nvidia.ko manually with the latest KOTD kernel. It's built and loaded fine. So, it's likely your nvidia build-setup problem.

whow! how did you do that? from where did you get your KOTD? which nvidia driver did you install? i did the following: 1. downloaded nvidia driver from http://www.nvidia.com/object/linux_display_amd64_180.22.html 2. extracted install-package with "NVIDIA-Linux-x86_64-180.22-pkg2.run --extract-only" 3. updated kernel from within yast from repo at http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/ 4. rebooted to runlevel 3 5. cd /usr/src/linux 6. make cloneconfig 7. make prepare 8. make modules_prepare 9. cd /tmp/NVIDIA-Linux-x86_64-180.22-pkg2.run 10. ./nvidia-installer -N then the installer stopped and in dmesg i could see the messages about missing symbols. -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

nvidia-gfxG01-173.14.15.

i did the following: 1. downloaded nvidia driver from http://www.nvidia.com/object/linux_display_amd64_180.22.html 2. extracted install-package with "NVIDIA-Linux-x86_64-180.22-pkg2.run --extract-only" 3. updated kernel from within yast from repo at http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/ 4. rebooted to runlevel 3 5. cd /usr/src/linux 6. make cloneconfig

7. make prepare 8. make modules_prepare 9. cd /tmp/NVIDIA-Linux-x86_64-180.22-pkg2.run 10. ./nvidia-installer -N

I'd build nvidia.ko directly by going to $NVIDIA/usr/src/nv and run "make module". Better to remove precompiled stuff, though. Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

In general you don't have to do it. Sometimes you need to fix the other side, though -- it's basically a problem of external driver trees. The include files and symbols needed to build kernel modules are already stored in /usr/src/linux*-obj/$ARCH/$FLAVOR. This directory is symlinked from /lib/modules/$VERSION/build, but some external drivers don't refer this correctly (or you may have some options to specify manually). But, nvidia driver tree seems to work as is. Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

VERY VERY STRANGE! it also works for me now! today i installed latest 2.6.27.13-5.1 from http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory and then i copied the files ".config" and "Module.symvers" from /usr/src/linux-obj/x86_64/default/ to /usr/src/linux/ then i went to /usr/src/linux/ and made "make prepare" and "make modules_prepare". then i did the usual "./nvidia-installer" and that's it. it worked this time! WHITHOUT CHANGING ANYTHING AT THE NVIDIA-DRIVER! so the problem MUST come from something inside the 2.6.27.13-2.1 from yesterday! or it was the "make cloneconfig" i did yesterday and the missing file Module.symvers in /usr/src/linux/. or the guys at suse/novell changed something in latest 2.6.27.13-5.1. -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Step back and think about this statement for a moment. Please realize that the nvidia driver is closed source and we have absolutely _NO_ control over what they do in their code. For their driver to be controlling the direction of the opensuse kernel seems to be exactly backwards, right? I understand that people get upset when their closed-source, GPL violating driver breaks, but why not talk to the people that create that driver instead of asking people who can't do anything about it?

at the time the problem occured, i didn't know, from where it came from. i updated kermel like i alwas do. i installed nvidia-driver like i always do. there was no problem in the past with that. kernel 2.6.27.12 worked perfectly with nvidia 180.22. and changing the kernel to 2.6.27.13 and installing the same nvidia 180.22 driver failed. so, of course, i thought of a problem in the latest kernel. ok, there have been made changes in 2.6.27.13 which are incompatible with nvidia driver. and the nvidia guys have to fix this. but as i said, it will not be good for us all, if this will not happen before this new kernel becomes some kind of "official". because in this case many many people will update to the latest official kernel through online-update or base-installation and will have black screens when using the proprietary nvidia driver. i hope this will not happen. -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
