$(usev modules "

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.")\
$(use amd64 && usev !abi_x86_32 "

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

390.xx libglvnd support is partial and requires different Xorg modules
for working OpenGL/GLX. If using the default Xorg configuration these
should be used automatically, otherwise manually add the ModulePath
from: '${EPREFIX}/${paths[XORG_OUTPUTCLASS_CONFIG]#/}/nvidia-drm-outputclass.conf'")\
$(usev x86 "

Note that NVIDIA is no longer offering support for the unified memory
module (nvidia-uvm) on x86 (32bit), as such the module is missing.
This means OpenCL/CUDA (and related, like nvenc) cannot be used.
Other functions, like OpenGL, will continue to work.")

Support from NVIDIA for 390.xx will end in December 2022, how long
Gentoo will be able to reasonably support it beyond that is unknown.
If wish to continue using this hardware, should consider switching
to the Nouveau open source driver.
