This patch adds support for m4u(Multimedia Memory Management Unit),
Currently it only support the m4u with 2 levels of page table on mt8173.
It is based on Robin Murphy's arm64: IOMMU-backed DMA mapping[1].
Hi Yong, Robin,
Hi Dan,
The quoted "arm64 iommu-backed DMA mapping" patch set is from 2015-February.
That was over 3 months ago.
What is the status of this work?
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.
Not on-list, at any rate, so there's no harm calling it out - helps me
get my priorities straight ;)
Thanks,
Robin.
