Hi Luca / All -
Like I mentioned previously, my machine conf didn't have the lines you indicated
PREFERRED_PROVIDER_virtual/libgles2 = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/egl = "libmali-xlnx"
Is there a reason why they aren't in the default machine conf for ZCU102 since
it does have the Mali 400 GPU?
When I do add them, I end up with this error:
ERROR: Nothing PROVIDES 'virtual/libgl' (but
/local/d6/easmith5/BuildOS/openembedded-core/meta/recipes-graphics/mesa/libglu_9.0.0.bb,
/local/d6/easmith5/BuildOS/openembedded-core/meta/recipes-graphics/glew/glew_2.0.0.bb
DEPENDS on or otherwise requires it)
mesa-gl PROVIDES virtual/libgl but was skipped:
PREFERRED_PROVIDER_virtual/libgl set to mesa, not mesa-gl
mesa PROVIDES virtual/libgl but was skipped:
PREFERRED_PROVIDER_virtual/libgles2 set to libmali-xlnx, not mesa
mesa PROVIDES virtual/libgl but was skipped:
PREFERRED_PROVIDER_virtual/libgles2 set to libmali-xlnx, not mesa
mesa-gl PROVIDES virtual/libgl but was skipped:
PREFERRED_PROVIDER_virtual/libgl set to mesa, not mesa-gl
I haven't had any luck trying to set the preferred provider for virtual/libgl
to get rid of this error.
In the recipe I'm currently working on I did also set RDEPENDS for
libmali-xlnx, but I'm not sure that worked properly. It seems to have built
fine, but I still don't seem to have the mali kernel module afterwards.
Do you have any further suggestions?
Thanks very much for your time!
Emily

kernel-module-mali is pulled in by libmali-xlnx:
$ git grep -B1 kernel-module-mali
.../libmali-xlnx.bb-RDEPENDS_${PN} = " \
.../libmali-xlnx.bb: kernel-module-mali \
Is libmali-xlnx built?
A few things to check, in top-bottom order:
1. your machine conf should have something like
PREFERRED_PROVIDER_virtual/libgles2 = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/egl = "libmali-xlnx"
2. libmali-xlnx should then be built
3. libmali-xlnx RDEPENDS on kernel-module-mali, so it should
be built as well
Bye,
