Hello Ville,
Apologies for bothering you.
Kms_prime goes through vgem_gem_dumb_create where the pitch gets calculated
which is not 64 byte aligned.
kms_prime->vgem_gem_dumb_create->intel_framebuffer_init which reports plane 0
pitch (5464) must be at least 64 byte aligned.
We have submitted thi
Thank you very much Mark, for testing the patch and providing the "Tested-by"
tag.
I shall incorporate you review comments and submit the patch.
Additionally, we have submitted the kernel alternative

Hello Ville,
Thank you very much.
Before reaching our i915's i915_gem_dumb_create, it goes to
vgem_gem_dumb_create for kms_prime.
The pitch gets calculated there and it is not 64 byte aligned. Due to this,
intel_framebuffer_init reports "pitch must be 64 byte aligned"
and framebuffer creation f
