NVIDIA – Possible Kernel 3.14 Patch..

Adventures With Linux ™ Posted on by

There is an article on DevZone that includes a possible Kernel 3.14 patch, from s_molgaard, for driver 331.38:  https://devtalk.nvidia.com/default/topic/683534/linux/331-38-on-3-14-rc1-kernel/ The patch format is – apparently – for kernel boot-time patching using dkms, which I don’t use..   So..  I just manually applied the changes shown for nv-linux.h to the Kernel 3.13 patch mentioned in my previous article https://rglinuxtech.com/?p=1032, … Continue reading →

There have been several ‘Kernel 3.13’ patches on various sites for the latest NVIDIA drivers, and I have finally found one that – on my system – actually works, without causing uvcvideo / usb problems (see previous articles..)

Kernel 3.14-rc1 – VMware OK, NVIDIA Fail..

Adventures With Linux ™ Posted on by

Just updated the test system to Kernel 3.14-rc1, and did the usual tests with the latest VMware (10.0.1) and NVIDIA (331.38). VMware compile failed with the VMware version of vmci, but this can be fixed by selecting the kernel.org versions of these modules, from the standard 3.14-rc1 source tree.   The vmci module can be found under ‘Misc … Continue reading →

NVIDIA have just released a new version of their ‘legacy’ 304-series driver – 304.119, but it still needs the usual patch for kernel 3.13.. modprobe: ERROR: could not insert ‘nvidia’: Unknown symbol in module, or unknown parameter (see dmesg) make[1]: *** [package-install] Error 1 make: *** [install] Error 2 Hopefully NVIDIA will release really up-to-date drivers soon, … Continue reading →

Kernel 3.13 in Linux VMware Guest – Shared Folders Problem

Adventures With Linux ™ Posted on by

Setting up a test system for the usb/uvcvideo tests, I have found another kernel 3.13 issue – this time with Linux as a VMware guest.. The shared folders – which work OK with 3.12, do not work with 3.13. Normally shared folders are found under /mnt/hgfs, but with 3.13 the hgfs directory is corrupted in some odd … Continue reading →

Back to 3.12.8..

Adventures With Linux ™ Posted on by

After some problems with uvcvideo / usb under 3.13 producing non-working camera and audio, and producing a ‘tombstone’, I have reverted to 3.12.8 for the time being..    More research is needed, and I have set up a 3.13 ‘guest’ under VMware to conduct further tests, without the ‘kernel taint’ of NVIDIA drivers, etc.. [50677.696508] cannot submit urb … Continue reading →

Kernel 3.13 – What’s New?

Adventures With Linux ™ Posted on by

The Kernel 3.13 mailing list announcement is – as usual – not very detailed, and in any case only shows changes since the last ‘release candidate’ (-rc8):    http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg572887.html For a much more detailed look at new features, etc., there is a very useful summary here: http://kernelnewbies.org/Linux_3.13 And..  More specific architecture/driver change information, here: http://kernelnewbies.org/Linux_3.13-DriversArch Robert Gadsdon.   January … Continue reading →

3.13 Final – And a VMware Patch You May Not Need..

Adventures With Linux ™ Posted on by

Installed 3.13 Final on my test system, and then on my main system, and encountered an odd problem with VMware (10.0.1).. On my test system, VMware had been compiling and installing/running OK on all the 3.13-rc versions, and 3.13 Final, but on my main system, vmnet failed to compile: … /tmp/modconfig-I1rVjt/vmnet-only/filter.c:206:1: error: conflicting types for ‘VNetFilterHookFn’  VNetFilterHookFn(unsigned … Continue reading →

NVIDIA: New Drivers – Still need Patch for 3.13..

Adventures With Linux ™ Posted on by

NVIDIA have released driver 319.82, and now 331.38, and they install OK on kernel 3.12, but – unfortunately – still need the patch for kernel 3.13, despite the fact that 3.13 Final is due in about a week from now.. modprobe: ERROR: could not insert ‘nvidia’: Unknown symbol in module, or unknown parameter (see dmesg) make[1]: *** [package-install] … Continue reading →
