Hi all, the following patches finally implement one of the longstanding TODO items in the etnaviv driver: per-process address spaces. They are only enabled for MMUv2, as switching the MMU context on MMUv1 would require a full stop of the FE, which I deemed too expensive to do on potentially every submitted commandstream. For now this only provides better isolation between GPU clients, but it is also a big step in the direction of supporting softpin. Softpin will later be used by GC7000 userspace drivers to deal with texture descriptors without the need to add even more relocation interfaces to the etnaviv UAPI. The changes are big and pretty disruptive, so I acknowledge that they aren't prime targets for a quick review, but I would appreciate a second pairs of eyes on them. FWIW, I've been running a variation of those patches for some time on GC2000, GC3000 and GC7000.
