Still in progress - I've been hampered a bit by having to rework a whole bunch of SMMU driver changes and other in-development stuff in parallel so I can do at least try to test as much as I can, not to mention various unrelated internal work. It also doesn't help that I also tried re-engineering things for v3 in a way that made some of it nicer, but turned out not to work so well elsewhere. > Is that still the most recent version of these patches? > If so, is there a plan when an update will be posted? > Or, is there an updated public git repo with a more recent version of > these patches? This is now my primary focus again, so I'll get an updated posting out by the end of next week at the latest. > My apologies if these questions have been asked and answered before > and/or elsewhere.
