[meta-xilinx] Mali Kernel Module for ZCU102

[Emily Smith]

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,
