Two problems actually.

First, gstreamer1.0-plugins-imx has its PxP plugin enabled.
Second, libimxdmabuffer's PxP allocator is enabled. This allocator is then tested for in the test-alloc program. This program is what's used by libimxdmabuffer's ptest. test-alloc then detects a failure while trying to use the PxP allocator (of course, since PxP is not actually present), causing test-alloc to report a failure.
I could change libimxdmabuffer's test-alloc to report success if at least one tested allocator works, but I'm not sure if this is really the right way to go. This would pave the way for run-time checks that enable/disable features. From what I know, this kind of thing isn't considered good practice in Yocto, since it tends to make builds less deterministic.

This is a problem, since the features between the different i.MX6 SoC
variants to differ. In particular, imxpxp is enabled because of this, even
though my nitrogen6x - which has an i.MX6 Quad - has no PxP support. As a
result, software whose recipes test for imxpxp presence incorrectly have
their PxP features enabled. This is especially bad if it affects ptest
packages, which then fail.

what is the ptest packages error, can you copy it here?
I now wonder what to do here. Split nitrogen6x.conf into multiple individualAt this stage of the product (entering legacy) we do not plan on

Also want to point out that even NXP SABRE SD machine does the same
thing  so I doubt the solution is splitting it or removing an
