- There's a warning about not finding the IRIS driver:
MESA_LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot

But from what I was able to understand, I was expecting it would be
available with mesa 21.0.3 since I've seen some commit about fixing
issue with it in the change logs.
I've tried to force the driver to both i965 and i915 but I either got
a
warning that this GEN cannot use it or still got the same fps.
Am I right to assume that it goes to a default driver that uses the
CPU
instead of the GPU?
Hello Simon,
I honestly don't know how Intel folks have overlooked this, but mesa in
yocto not only does not enable iris, the mesa recipe does not even have
an option to enable it.
However, it should be pretty easy to add. Please take a look at
poky/meta/recipes-graphics/mesa/mesa.inc, specificially any lines that
mention GALLIUMDRIVERS and matching PACKAGECONFIG,
and you should be able to add iris there, and rebuild your image. Then
you can submit your first patch to yocto via oe-core mailing list ;)
Alex
Hello Alex,
I was able to fix the iris driver issue with the following added to
mesa.inc
GALLIUMDRIVERS_append = "${@bb.utils.contains('PACKAGECONFIG', 'iris',
',iris', '', d)}"
I will look into sending the patch
thanks a lot for your help
Simon
