Anyway, what are your thoughts on taking this for 4.4? Since the
dependencies are now in and we're at -rc5 already, I'm on the verge
of reposting a self-contained version to go through arm64, as we
really need to unblock all the follow-on development there (it's a
shame that of the people I'm aware want this, it's only me and the
Mediatek/Chrome guys here on the list saying so).
I plan to take it for 4.4, given the missing ack arrives. What are your
plans to resolve the remaining issues, like with the probe deferral
patch-set?
That's great, thanks. I've been keeping an eye on the on-demand probing
series[0], and now that things are looking promising there I'm having a
go at pulling it in as it lets us solve the device dependency issue in
an even neater way than deferral. With the rest of Laurent's patches to
move the OF dma_ops configuration into the probe path, I just need to
finish working out how to handle probe failure/deferral, and we should
be good to go. That's my priority for 4.5, in parallel with properly
wiring up the ARM SMMU driver to work nicely with this stuff.
Sorting out the configuration order also gets us a lot closer to
handling multiple IOMMU drivers for platform devices, and moving 32-bit
ARM over to the common code - plus I now have some RK3288 hardware which
can serve to test both of those, too.
Robin.
