Like all out-of-tree kernel modules, it is necessary to rebuild
${PN} after upgrading or rebuilding the Linux kernel
by for example running \`emerge @module-rebuild\`. Alternatively,
if using a distribution kernel (sys-kernel/gentoo-kernel{,-bin}),
this can be automated by setting USE=dist-kernel globally.

Loaded kernel modules also must not mismatch with the installed
${PN} version (excluding -r revision), meaning should
ensure \`eselect kernel list\` points to the kernel that will be
booted before building and preferably reboot after upgrading
${PN} (the ebuild will emit a warning if mismatching).

See '${EPREFIX}/etc/modprobe.d/nvidia.conf' for modules options.")\

Note that without USE=abi_x86_32 on ${PN}, 32bit applications
(typically using wine / steam) will not be able to use GPU acceleration.")
