Linux

All,

Updated my kernel to 4.9.8-201fc25 today and found out the NVIDIA-Linux-x86_64-375.26 drivers do not compile.

Supposedly this shouldn't be a problem according to some forums, but for me it is. There is a patch available at https://devtalk.nvidia.com/default/topic/972761/linux/linux-4-9-git-rc1-375-10-build-errors/, the relevant bits are included in the code block below.

If you have "nvidia-installer" hanging at 20% when compiling, this issue is likely the cause.

There was also some bugger-up for me in the Makefile shipped with the installer ("$(RM) -r conftest" needing commenting out in ./kernel/Makefile). Everything worked fine after commenting out the mentioned line and patching the code.

• Extract the package with: "./NVIDIA-Linux-x86_64-375.26.run -x"
• Check the issue is the same via "cd ./NVIDIA-Linux-x86_64-375.26/kernel" and "make" (GET_USER_PAGES errors)
• Use "make clean" to get to a decent state.
• Put the patch below somewhere sane (e.g. /tmp/nvpatch) and apply it with: "patch -p1 < /tmp/nvpatch"
• Run "make" to save time later.
• Re-run the installer: "cd ../ && ./nvidia-installer -a"

If you're still finding the installer is crap, manually deploy the nvidia-drm.ko kernel module compiled in ./kernel/ and reboot.
