Is it possible to allow my chroot to use the same Nvidia Drivers as my host os? Drivers are proprietary / not included in the Kernel.
1 Answer
The proprietary Nvidia driver consists of multiple parts:
- kernel modules:
nvidia-drm.ko,nvidia.ko,nvidia-modeset.ko, and in newer versions, alsonvidia-peermem.koandnvidia-uvm.ko. If DKMS is used, these can be found in/lib/modules/$(uname -r)/updates/dkms/. Since a chroot uses the same kernel as the host OS, you don't need to copy these into a chroot. - some utilities in
/usr/lib/nvidia/ - some utilities in
/usr/bin/nvidia-* - a number of OpenGL, OpenCL and VDPAU libraries in
/usr/lib[64]/or/usr/lib/x86_64-linux-gnu/, depending on distribution - configuration file
/usr/share/X11/xorg.conf.d/nvidia-drm-outputclass.conf - an X.org X11 server driver in
/usr/lib/xorg/modules/drivers/nvidia_drv.so(or wherever your distribution places the X server driver modules) - an X.org X11 server extension module in
/usr/lib/xorg/modules/drivers/libglxserver_nvidia.so*(or wherever your distribution places the X server extension modules)
Unless you run a separate hardware-accelerated X server (and thus a separate physical display) for your chroot, you'll only need the libraries and maybe the utilities, depending on what the chroot is actually for.
You can certainly copy (or perhaps mount --bind) the libraries and the utilities into your chroot. I'd recommend writing a script or a Makefile to handle the actual copying, to make it easier to re-copy things into the chroot after a driver update.
