Here's v3 of the panfrost driver. Lot's of changes from review comments and further testing. Details are in each patch. Of note, a problem with MMU page faults has been addressed improving the stability. In the process, the TLB invalidate has been optimized which Tomeu says has improved the performance some.
Several dependencies have been applied already, but the first 2 patches are the remaining dependencies. We need to take the iommu change via drm-misc or we need a stable branch. I'm hoping this is the last version. I'm hoping to apply this to drm-misc this week before -rc5 cutoff. A git branch is here[1].
