Well, that is indeed unknown...

The tiler things for the Pyra mainly rotate the framebuffer
so that a text console or /dev/fb0 is rotated properly.

X11 using DRM can rotate independently.

If you look at the new demo video, the orientation between
pyra and beaglebone black is 90° because the tiler is not
active with SGX...

Ok, I see.

Yes, that looks like a good strategy.

Maybe we do not have to really activate linux_openpvrsgx the
DDK1.9 unless it would help to better understand/test the

Anyways, your testing-v5.4 is a good test-bench to compare against.

Looks like:

echo 1.14.3699939 >/sys/..../pvrsgx/version
