R11:f32b188cc39a: x11-servers/xorg-server: add missing features for PRIME

Summary

Modern PRIME X11 setups autoconfigure themselves, which internally

uses the udev and udev_kms options to do so. These options are required
for X to find the available DRM devices. This is needed for PRIME on
FreeBSD.

This is also adds the DRM platform code, taken from X commit:

https://gitlab.freedesktop.org/xorg/xserver/-/commit/5468123822bbe8cd0a0abe07bbbd3a9cb14ed2cb

Which is in master but not yet in any releases. This adds the platform
code to the build for DRM so that PRIME setups can work.

LGTM but you need to bump PORTREVISION too.
And maybe merge D39887 in so we will not bump PORTREVISION twice ?

Updated to merge in D39887 and bump PORTREVISION

This seems to break setups with an additional video card designed for but not yet configured for PRIME:

(EE) Fatal server error:
(EE) AddScreen/ScreenInit failed for gpu driver 0 -1

All without any xorg.conf.

Also fails on a system with only one GPU, an Intel integrated:

Same result on a more recent -CURRENT, dated after the commit introducing this update.

Mhm, I had only tested on my AMDGPU box and didn't saw any problems, @ashafer_badland.io do you have any idea ?

I think it's because you're missing the files in xorg.conf.d? You need something like this:

$ cat /usr/local/etc/X11/xorg.conf.d/20-intel.conf
Section "OutputClass"
    Identifier "intel"
    MatchDriver "i915"
    Driver "modesetting"
    Option "PrimaryGPU" "yes"
EndSection

We don't install these files by default yet, that's the next thing I'll be sending out.

For more details see https://badland.io/prime-configuration.md

Or for the single-GPU system a normal xorg.conf

Neither of these systems have xorg.conf, and should never have one if only using modesetting on the Intel GPU. Nothing in xorg.conf.d either. ~~Shipping 20-intel.conf may be a good idea, but~~ users should not be creating files for a default configuration that has worked for time.

Even on Linux there were no files in xorg.conf.d (or xorg.conf for that matter) necessary for modesetting to work by default on an Intel GPU. Back when I ran Linux on the PRIME-capable machine, I had a very skeleton xorg.conf like so to enable PRIME offloading:

Section "Module"
        Load "modesetting"
EndSection

Section "Device"
        Identifier "nvidia"
        Driver "nvidia"
        BusID "8:0:0:0"
        Option "AllowEmptyInitialConfiguration"
EndSection

which does not have any other configurations tucked away in xorg.conf.d shown in the blog post. Maybe try to figure something better out that allows a full xorg.conf-free autoconfiguration to continue working as before, and for PRIME just this skeleton xorg.conf.

Here's the rundown of my testing: on my three laptops things look to be working as I expected. I don't replicate anything like what you're seeing on the single-GPU system but I'll get to that later and maybe we can figure out what your issue is. Here's what I see:

On my single-GPU Intel laptop it starts properly with no xorg.conf or 20-intel.conf.
On my Intel+NVIDIA PRIME laptop it works with no xorg.conf.
- 20-intel.conf is not required if nvidia-drm.ko is loaded, the 20-nvidia-drm-outputclass.conf from the blog post is however.
- If nvidia-drm.ko is not loaded, then the X server sees two devices and isn't sure which one to use, so it bails and tells you to specify frambuffer busIDs. This is where 20-intel.conf will fix things, as it tells X which one to use. I'll have to check out on Linux if this is the same behavior. I wouldn't be surprised if it is since they usually expect nvidia-drm to be present therefore avoiding the issue, but we'll see.
On my Intel+NVIDIA PRIME laptop your skeleton xorg.conf from your last comment works fine.
On my AMD+NVIDIA PRIME laptop it works with no xorg.conf, configs from the blog post.

The above portions of the log you added show HDMI-1 and HDMI-1-1 outputs. These correspond to the modeset(0) and modeset(G0) cards that X detects. I find this odd since this "G0" name usually refers to the second GPU in a hybrid graphics laptop, but in your case they are using the same Intel card. This is for the single GPU Intel system correct? I do not see this pattern on mine. Any more details you can provide about the machine?

Can you please try with libudev-devd 0.5.1, the latest in ports, if you aren't already? It has a fix for autoconfiguration that I haven't seen cause your error message but still might affect you. I should probably the dependency from xorg-server to require udev 0.5.1, especially if that's your missing piece.

Thanks for testing Austin.
I've quickly tested on my main machine, an Intel NUC (so only one Intel GPU) and I don't have any problems too.
So yes I think that @vishwin have something patched locally or not all ports up to date.

Yeah I was indeed using a libudev-devd from a revision newer than 0.5.0 but not 0.5.1. The single Intel GPU machine, a Seeedstudio Odyssey, which has HDMI as its only video out, works after updating. Still need to test the other machine.

Also works with Intel/modesetting only on the PRIME-capable machine after updating libudev-devd. Still need to see about actually configuring PRIME on it, but that's a separate thread.
