Hi folks, as of when the next rebuild happens [1] the kernel for ppc should now boot okay. This has been tested with servers (G3 & G5) only and how it behaves with the multitude of graphics cards apple shipped with their machines is an unknown. Below is the chat I had:
(22:55:56) phillw: xxxxx: do you know if linux-ppc [powerpc] > (saucy-proposed) [3.11.0-0.1] is the kernel that will get ppc desktops back > working? > (22:56:11) xxxxx: phillw: Should do, yes. > (22:56:27) xxxxx: phillw: I just smoketested it on my G3 and G5, and both > work. > (22:56:57) phillw: great, so the cron build tomorrow should put the > ppc-lubuntu testers back in the chase? > (22:57:45) xxxxx: phillw: Depending on how quickly I get it migrated, but > probably yes. > (22:58:38) phillw: xxxxx: scheduled to start at 16:29 (UTC) is that > enough time for you? > (22:59:22) phillw: or would you prefer an extra 24 hours? > (23:00:43) xxxxx: Oh, indeed, it's almost a day until the next build. > Yeah, that one should be fine. > (23:01:31) phillw: xxxxx: okies, if you are sure, I will email the > testers, obviously they are chomping on the bit to get back to work! > (23:02:43) xxxxx: I make no guarantees that various DRM/KMS drivers are > working (I don't run consoles on any of my PPC machines, they're all > servers), but these kernels at least boot on all my kit, which is a step up > from the previous version. :P > (23:03:05) phillw: there's one sure fire way to check :P > (23:03:27) xxxxx: 3.11 includes a pretty massive changeset to the radeon > driver, so that could cut both ways. Maybe it's drastically improved, or > maybe it has a ton of new bugs that break it on !x86... We'll see. > (23:04:55) phillw: as always, we rely on the testers to let us know :) > That the promise to have a kernel that at least stood a chance of working > has been kept, they will be happy and do not 'rant' over bugs. > (23:05:42) xxxxx: Well, I can nearly guarantee that it should boot on > pretty much any hardware we've supported before. Between yyy and I, we have > a pretty wide array of stuff to boot and stress test on. > (23:05:49) xxxxx: It's just that he and I both only run headless servers. > (23:05:51) xxxxx: So, we'll see. :) > (23:07:07) phillw: the graphics cards that apple used were and are always > an issue... they have gotten used to workarounds, only by letting it into > the wild can these issues with the graphics cards be started to be > investigated :) > (23:07:38) phillw: xxxxx: many thanks to you and yyy for this work, I do > know ppc for desktops is a low priority :) > (23:07:42) xxxxx: It's not the cards, per se, it's that the radeon driver > has become very x86-centric, and very few people care about fixing the PPC > bugs with it. > (23:08:09) xxxxx: nouveau seems to suffer fewer of those issues (for > whatever reason), so the nvidia cards that Apple shipped with later G5s > seem to be in better shape. > (23:09:35) phillw: we're still working with G3's and g4's... as long as > the darn thing will boot, the graphics cards could be seen as nearly a > seperate branch of their own. > (23:10:19) xxxxx: Yeah, I haven't tried running X on the ATi Rage128 in > my G3 for, like, a decade. > (23:10:38) xxxxx: I assume it probably sort of works. But I have no idea, > and don't care, as it's a headless router/firewall in my house. :P > (23:11:14) xxxxx: Though, the offb driver would work for boring old 2D X. > You'd just get zero acceleration. So, allow the daily to build and start testing!!! Regards, Phill. 1. https://wiki.ubuntu.com/Lubuntu/Testing#When_do_they_build.3F -- https://wiki.ubuntu.com/phillw
