Congratulations! That is IMHO another important milestone for our project.

Time will find a solution :)

I can't exclude that...

Fine.

I have looked into the testing-v5.4 tree and it is based on
DDK 1.9.2253347 which we also have in the linux_openpvrsgx tree.

I am almost done with rearranging the branch names and moving all
files to drivers/gpu/drm/pvrsgx so that we will have a cleaned up
(and hopefully stable) basis very soon.

Then you can add required patches to the (new) letux/pvrsrvkm-1.9.2253347
branch and it should work by choosing CONFIG_PVRSGX_1_9_2253347=y.

I'll write a description here to this list when it is done.

New patches for the command translation layer can then go to
letux/pvrsrvkm.

BR and congrats and thanks,
Nikolaus
