[v3,0/3] Initial Panfrost driver

Message

Rob Herring April 9, 2019, 8:54 p.m. UTC

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].
