While we initially provided automatic installation of the NVIDIA driver as a convenience, we then ran into the complexity of dealing with users wanting to configure pci-passthrough and/or vgpu, and to possibly move across these configurations post-deployment (see canonical#362, canonical#379). After some more discussions, we agreed that deploying a gpu driver is not the responsibility of hardware-observer, but rather of the principal charm that needs to use the gpu (e.g. nova or kubernetes-worker). This commit therefore drops the functionality of automatically installing the driver and determining if it has been blacklisted for a simpler workflow of installing DCGM only if a driver is found to have been installed and loaded. Fixes: canonical#379

In revision 146/147 we improved the NVIDIA gpu detection algorithm by checking for module blacklisting, and avoiding deploying dcgm in that case (see #363).
The check is too generic though, as
nvidiafbis always blacklisted via/etc/modprobe.d/blacklist-framebuffer.conf, which is shipped by default via thekmoddeb package.The text was updated successfully, but these errors were encountered:
