I don't know. I didn't write this. However, doing some investigation, the big difference here is the overall capabilities. There are common distributions where a user may want to use mesa (no external libdrm) as well as distress where they want to use an external drm and the mesa-gl version only. So 'mesa' and 'external drm + mesa-gl' are equivalent in functionality for a given distro. Only difference being optimization. You may ask why would I use one vs the other. In my case, we have a family of SoC parts. Some of the family have a Mali graphics chip on them, while others don't have any optimized graphics so everything has to be software rendered. The only difference (from a software point of view) is if the Mali is on-board or not. So using a common (binary) distribution, and being able to just swap those parts is highly desirable.

FWIW, we also expect SW rendering for GL, while SGX/RGX cores in our SoCs
accelerate EGL/GLES.
But, like Mark, I also don't know much about Mesa. Similar to what he
mentioned about Mali, we used to require a custom libdrm years ago. But
since then, everything has been upstreamed into main libdrm-omap driver.

I've included the link to my commit in meta-freescale layer, where the
PACKAGECONFIG is set to use 'classic' OSMesa and adds swrast to
DRIDRIVERS. This should turn the rendering to be performed in the SW,
effectively working for all backends (at the obvious performance
penalty). It took me quite some digging to figure this combination
out, as I also cannot claim myself an expert in mesa...

Maybe something like this could be used (warning: untested):
PACKAGECONFIG ??= "opengl dri ${@bb.utils.contains('DISTRO_FEATURES',
'x11', 'x11', 'osmesa',d)}"
DRIDRIVERS_append = "${@bb.utils.contains('DISTRO_FEATURES', 'x11',
'', ' swrast',d)}"

Do you have a pointer to that anywhere? I'm curious if any of it might
still apply.. but I know nothing about mesa and what configurations are
even possible.

I don't know any any reasons we couldn't do this.. but like I said.. I'm a
newbie when it comes to mesa.

I believe I was fighting similar issue in meta-freescale layer for
imx8mm derivative [1], where the status of GPU support was not know at
the time. What I did back then is set the default configuration to
osmesa and used swrast in order to be able to use mesa on that
derivative. After that, when GPU support has been added into Mesa -
those modifications were reverted.
I guess turning to swrast in case if someone would decide _not_ to use
X11 - is not a bad option here, rather than enforcing the X11 for
distros which are using this recipe. Any thoughts?

With the abomination that is libmali (and similar), it is still needed.
It's the only way to support GL on a primarily GLES compatible system.
The problem is the way they do this seems to be a custom version of
libdrm, which then conflicts with the mesa version. Thus the issues.
I'm happy to continue testing my particular needs now and the future (thus
the patch against master.)
What we absolutely don't want is a different version of this for every
system that has a custom graphics chip in it. That would be a far larger
nightmare than what is currently implemented. The key to this is to come
to an agreement on what should work and how it should be configured. As
of right now, the only working configuration I can find is X11.

Re: [OE-core] [PATCH] mesa-gl: The purpose of mesa-gl is to provide for X11 usage
To be honest, I would just take the entire recipe out. It's causing trouble
during updates, isn't being tested neither for builds nor at runtime, and
is supposed to provide some specific configuration which as this discussion
makes clear, nobody seems to quite understand.

This can be further refined to:
conf/local.conf:
PREFERRED_PROVIDER_virtual/libgl = "mesa-gl"
PREFERRED_PROVIDER_virtual/mesa = "mesa-gl"
DISTRO_FEATURES_append = " opengl"
DISTRO_FEATURES_remove = "x11"
bitbake mesa-gl
Error is the same:

Have you tried any of these? This hasn't been working since Zeus with an
external libmali and non-X11 configuration. It returns the error listed
in the commit message "ERROR: Problem encountered: building dri drivers
require at least one windowing system or classic osmesa" during
configuration.
Ross and I talked about it and he said this was specific to X11
implementation and wasn't meant to work for other implementations.
(fbdev/QT/etc.)
If Wayland is supposed to work, then someone needs to go in and adjust the
configuration to also support Wayland. I don't have any Wayland systems
to even know what the right configuration COULD be.
The specific configuration I'm running has "OpenGL" in the DISTRO_FEATURE,
but does NOT have X11 or Wayland".
DISTRO_FEATURES_append = " opengl"
DISTRO_FEATURES_remove = "x11 wayland"

Hmm. That's not good. There are embedded devices that provide EGL/GLES support
through own stack, but fall back on MESA for full desktop GL support. That's
been working to some extent even with Wayland and w/o X11. With your change
that won't be possible any more...

[OE-core] [PATCH] mesa-gl: The purpose of mesa-gl is to provide for X11 usage
Trying to build mesa-gl without X11 enabled, results in numerous errors
about being incorrectly configured, such as:
ERROR: Problem encountered: building dri drivers require at least one
windowing system or classic osmesa
After consulting with the author of this recipe, it was clear that it
was only intended for the X11 use-case, so requring X11 should avoid the
error message above.
