It also has a lot of arm-nommu changes, which is my interest at the moment as I'm porting something from 2.4 which isn't in anyone's tree, but is yet another arm-nommu variant. I don't know if I would find all the things I need in the mainline kernels. > in terms of nommu-specific changes, those largely come from David > Howells and dont see the uClinux-dist tree until they're mainlined > (or Greg merges them). I'm not sure about that. I see quite a few nommu-specific changes in the uClinux-dist tree relative to the same mainline kernel version. I had hoped to see the not-ready-for-mainline nommu changes in David Howells nommu.git :-), but that doesn't seem to see much action. We can't have everything I guess :-) > the kernel we ship with the Blackfin releases for example hasnt used > the uClinux-dist kernel in years. we find it easier to stick to > mainline and get our ADI vendor changes (Blackfin/ADI drivers) > merged directly. any nommu problems we have go through David > Howells and lkml (generally with a uclinux- dev cc to keep people in > the loop). That sounds like a good plan. It's what I'd do. My specific reason for looking at uClinux-dist is needing to target another arm-nommu architecture, and not sure if everything needed for stability on the relevant nearest devices is in mainline or not. And to see if there are arch-independent nommu changes in uClinux-dist that are slow getting mainlined, because I need to work with another completely different nommu architecture too. I'm about to embark on some core nommu memory management changes to help with fragmentation resistance. If the patch flow for generic nommu is via David Howells -> mainline -> uClinux-dist, then I can monitor mainline, but if it's David -> Greg -> uClinux-dist sometimes, then I need to monitor uClinux-dist releases because I'm not sure where else I'd find them. I find lkml impossibly high traffic -- unsubscribed a few years ago due to that -- so I don't know what passes through there these days. If the most interesting patches are often only appearing there, I guess I will need to write some list-processing tool to draw my attention to patches which I'd likely be interested in. But not until I've exhausted the question of existing trees and such :-) And lo, a google for David and I find uclinux-dist-devel which I hadn't noticed before. Perhaps I should subscribe there.
