Solved graphics/nvidia-drm-kmods depends on x11/nvidia-driver

Hi,

does anybody known why nvidia-drm-kmods RUN_DEPENDS on x11/nvidia-driver? I created local poudriere repo for building kmods and was surprised nvidia-drm-kmods brings looots of dependencies.
 
It uses the NVidia driver (more specifically, the 'blob' NVidia supplies with their driver). What were you expecting?

As the maintainer who did it, it's intentional and unavoidable at least with current form.

For conventional, old-school UMS driver (in contrast with KMS), installing x11/nvidia-driver{-304|-340|-390|-470|-580|-devel} as before pulls corresponding x11/nvidia-kmod{-304|-340|-390|-470|-580|-devel} in. So no worries.

On the other hand, when the change was made, graphics/nvidia-drm-{510|515|61|66}-kmod depended on x11/nvidia-driver, as kmods part was NOT YET splitted out from it.

When the split was done as per request from kmod builder admins, graphics/nvidia-drm-{510|515|61|66}-kmod, which are actually the kmod ports, are no longer allowed to depend on x11/nvidia-driver, but depending on x11/nvidia-kmod was still allowed by the admins. So the dependency was switched.

But to use above-mentioned "actual" kmod ports to run X11 (Xorg or XLibre) or Wayland, any one of x11/nvidia-driver{-304|-340|-390|-470|-devel} supporting the GPU to be used is mandatory.

So, knowing it's NOT 100% ideal way, we (NVIDIA driver ports team) decided to pull x11/nvidia-driver{-devel} in from graphics/nvidia-drm-kmod{-devel} ports, which are metaport to choose which actual kmod port to pull in as per OSVERSION.

graphics/nvidia-drm-kmod{-devel} itself doesn't build anything. Just for convenient metaport to automatically pull in actually needed components, directly and indirectly.

And after the split / reconstruction is done, -580 variants are added as new legacy branch for GPUs that NVIDIA dropped supports from Production Branch of their drivers starting from 595 branch (actually, dropped from earlier New Feature Branch, 590 series).

More, in addition of graphics/drm-612-kmod, corresponding graphics/nvidia-drm-612-kmod{-580|devel} were added.

Note that graphics/nvidia-drm-kmod/Makefile.common is NOT used by graphics/nvidia-drm-kmod port itself, but it's there just to be included from each actual kmod ports, not to make common parts out of sync by accident.

I think this statement deserves explanation. Running X with the "nvidia" driver requires /usr/local/lib/xorg/modules/drivers/nvidia_drv.so which is shipped by nvidia-driver. But does using "modesetting" via nvidia-drm really require all those nvidia-driver libs?

My understanding is yes.

Each graphics/nvidia-drm-*-kmod (master port of corresponding graphics/nvidia-drm-*-kmod-580 and graphics/nvidia-drm-*-kmod-devel) installs /usr/local/share/X11/xorg.conf.d/20-nvidia-drm-outputclass.conf, which should be picked as system default. Linked above is the source file (20-nvidia-drm-outputclass.conf.in) that %%LOCALBASE%% is replaced with configured LOCALBASE (default: /usr/local).

For this, ashafer should have the best explanation, as the codes for nvidia-drm.ko provided by NVIDIA side is his work, and graphics/nvidia-drm*-kmod ports are initially created by him.

And /usr/local/lib/xorg/modules/drivers/nvidia_drv.so is NOT the only library x11/nvidia-driver{-304|-340|-390|-470|-580|devel} provides.
You can see, for example, below in /var/log/Xorg.0.log.

Xorg might just load all modules it finds in /usr/local/lib/xorg/modules/drivers.

Try removing /usr/local/lib/xorg/modules/extensions/libglxserver_nvidia.so and /usr/local/lib/xorg/modules/drivers/nvidia_drv.so

Keep in mind, nvidia.ko is from x11/nvidia-kmod, not from x11/nvidia-driver. So nvidia-driver is needed for Xorg, not for a drm. Anybody can install nvidia-driver by hands. Or without breaking anything it can be an optional dependency in nvidia-drm-kmod, like:

Makefile: 
OPTIONS_DEFINE= RUNTIME
OPTIONS_DEFAULT= RUNTIME

RUNTIME_RUN_DEPENDS= nvidia-driver${PKGNAMESUFFIX}>0:x11/nvidia-driver${PKGNAMESUFFIX}

Actual DRM/KMS (additional) kmod ports, graphics/nvidia-drm-{510|515|61|66|612|latest}-kmod{-580|-devel} are basically for adding hybrid graphics (aka Optimus) support. This is because recent iGPUs want DRM/KMS to work, so running NVIDIA dGPUs with iGPUs without using tricky way using OSMESA (Off Screen MESA) need DRM/KMS supports.

As I've shown in comment #7 here, libraries and others provided by x11/nvidia-driver{-580|-devel} are still needed even on DRM/KMS environment.
graphics/nvidia-drm-*-kmod*, corresponding graphics/drm-*-kmod and corresponding x11/nvidia-kmod* kmod ports alone are insufficient.

This was because graphics/nvidia-drm-*-kmod originally depended upon x11/nvidia-driver before kmod parts are splitted out to x11/nvidia-kmod*.

And, as far as I could hear from kmod builder repo's admins, kmod ports built built on the builder are NOT allowed to pull in non-kmod dependencies like x11-servers/xorg-server or alike as of the limitations in resources and how builds are done there.

So we needed to somehow pull in corresponding x11/nvidia-driver* at least on initial installation outside ACTUAL kmod ports, so we chose graphics/nvidia-drm-kmod* metaport to do so, as it's NOT ACTUAL kmod ports.

So the option would be meaningless. Or does any of Wayland compositor work without x11/nvidia-driver* ports installed? If so, the option should be WAYLAND, not RUNTIME. But I think it would be falling back to scfb (for UEFI boots) or vesa (for legacy BIOS boots) as NVIDIA drivers doesn't work.

I see now. This config causes loading of nvidia_drv.so, which means that nvidia-driver is indeed a required runtime dependency.

What use does DRM have without DRI (which is the case for nvidia-drm, if I understand it correctly)? I doubt you can use nvidia-drm in headless scenarios, but even if you can it is too much niche to add an option to the port. But I'm not a maintainer anyways.

DRM (Direct Rendering Manager) and DRI (Direct Rendering Infrastructure) are underlying infrastructures for X11 / Wayland, but not all of infrastructures.

And DRM for managing resources and accesses by DRI. So both can be considered as (quite roughly) a 2 aspects of single thing. Implementing single needed things via different aspects.

DRM cannot run without the existence of DRI, and applications and middlewares (including X11 and Wayland) should NOT access DRI without arbitrations by DRM in resources and access control.
