You mean that the responsiveness / control of latencies is the other thing
that's needed? Yep so it is. But getting the infrastructure in place doesn't
hurt because this is something many people (including self) need and Ken
over at Intel is the only one actually doing something about it.
Getting SPI slaves to actually work by spawning their worker threads as
realtime under that patchset is of course a larger issue. One does not
exclude the other tho.
Yours,
Linus Walleij
