This is true, yes. Shouldn't be too hard to backport; if there's still
interest in Midgard 1st/2nd gen, I suppose I can grab hardware and sort
it out...

ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but
have a few differences. Add a new format type to represent the format. The
input address size is 48-bits and the output address size is 40-bits (and
possibly less?). Note that the later bifrost GPUs follow the standard
Here's v2 of the panfrost driver. Lots of improvements from the RFC
primarily with support for job hangs resetting the GPU and runtime-pm
thanks to Tomeu.
Several dependencies have been applied already, but the first 2 patches
are the remaining dependencies. We need to take the iommu change via
Similar to the single handle drm_gem_object_lookup(),
drm_gem_objects_lookup() takes an array of handles and returns an array
of GEM objects.
