Uh, I guess we want a "depends on IOMMU_SUPPORT" instead of "select
IOMMU_SUPPORT" in panthor then.
That works for me.
Let's revert the faulty commit first. We'll see if Steve has a
different solution for the original issue.
FWIW, the reasoning in the offending commit seems incredibly tenuous.
There are far more practical reasons for building an arm/arm64 kernel
without PM - for debugging or whatever, and where one may even still
want a usable GPU, let alone just a non-broken build - than there are
for building this driver for x86. Using pm_ptr() is trivial, and if you
want to support COMPILE_TEST then there's really no justifiable excuse
not to.
Thanks,
Robin.
