I didn't succeed at getting something postable. :( I could easily repost some of the earlier patches (like fixing aligned memory, etc) if there's a desire for those, but I figured I'd wait until I had something postable for the microframe scheduler. I've definitely made progress in the last few days and things are a bit cleaner at <https://chromium-review.googlesource.com/#/c/313808/3>. It's also working reasonably well, but I'd still like to understand some of the behavior I'm seeing before I actually post it to the mailing list. I'm going to be away from my computer for about a week, so I'll plan to pick this up again when I'm back... -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
