Some machines have hardware-specific GL drivers that do EGL and GLES (many ARM
boards). Others have their own EGL/GLES drivers and provide a Mesa DRI driver
(EMGD). Previously adding Mesa, for software GL/GLX rendering in the first case
and hardware GLX in the second, involved bbappends and changing Mesa to be
machine-specific.
By adding a just-GL Mesa the machine definition can combine it with the hardware
drivers cleanly.

Hi Ross,
This is a clever way to deal with unnecessary rebuilding of mesa we were seeing earlier. With this mesa-gl,
the mesa also need modification to remove gl from the default recipe.
Also looks like there is a need from community for mesa-gl-lib and mesa-gl-headers, as some
platforms need just the mesa-gl-headers and not the libs.

Ross, Nitin,
This is a great and very welcomed development! This would definitely allow our
TI machines (and other ARM ones, as you said) to happily co-exist with Mesa
software rendering.

No, mesa and mesa-gl intentionally conflict. mesa-gl provides GL,
emgd-driver-bin provides EGL and GLES, your machines shouldn't need
both mesa and mesa-gl.

To be honest GL platforms that don't ship their own headers are
*totally broken* and using mesa's headers is basically the same as
crossing your fingers and praying to $DEITY. Platforms that do this
need to be fixed, not worked around, and taking Mesa's headers without
editing them is just wrong.

With few more fixes, this is working for EMGD based meta-intel BSPs.
Here are the commits which worked:
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=nitin/mesa-gl
http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-contrib/log/?h=nitin/mesa-gl
BTW the same functionality can also be implemented by customizing current mesa
recipe based on a new machine feature which can be called as
"custom-gles" or "no-mesa-gles"
BTW in other context, this does not help for the rebuild issue RP was mentioning earlier.
Thanks,
Nitin

The dependency on "mesa" is actually right, any other GL
implementation may or may not provide the DRI interface, which is what
X is depending on.
I've updated my mesagl branch to add a virtual/mesa provider.

Add a preferred provider of virtual/mesa="mesa-gl" in here and I think
you'll be sorted.

Hi Ross,
I have updated my branches accordingly here.
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=nitin/mesagl
http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-contrib/log/?h=nitin/mesagl
I have tested this with emenlow BSP. If it looks ok to you, I can send these for upstreaming.
Thanks,
Nitin

The change to separatebuilddir.inc seems wrong and I merged your dri
change to mesa-gl.bb into my branch which had moved on since you
looked at it. You won't need a PROVIDES in mesa-gl as it's in
mesa.inc.
I'll send my branch shortly.

Looks good to me.

Ross,
The PROVIDES from mesa.inc is not what mesa-gl recipe provides. Mesa-gl is dropping
gles & elg components, and that should be reflected in the PROVIDES. Right?
