Hi Pekka,
I finally got everything working. I am using gbm_bo_create() and
gbm_bo_get_fd() to get a buffer that is filled by my grabber. Then I
use eglCreateImageKHR() and glEGLImageTargetTexture2DOES() to display
it.
My only problem left is that glEGLImageTargetTexture2DOES() does only
accept

I have a grabber device on The PCIe-bus that is able to transfer image
data to other PCIe devices.
I want to setup a wayland client, that reserves a buffer in GPU
memory. Then the grabber could DMA to the buffer address. After
finishing the transfer, the client could flip the buffer.
Is there
I did a git bisect and found the commit "244244d1 (refs/bisect/bad)
compositor-drm: Use GBM modifier API" introduced the problem.

Perhaps I should add, that with rolling back to weston 4.0.0.
everything works fine. So nouveau support must have been broken
somewhere inbetween.

When I start weston it hangs with repeated error messages (see log).
Starting with --use-pixman works fine.
