Awesome! What machines are they? Maybe they are Power4+ ? I asked 1 year ago if anyone was using Power4, and got no responses: https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156213.html I realise you probably don't follow the mailing list, perhaps I should have Cc'ed debian-powerpc or some other lists. Anyway if you are actually using mainline on a Power4 then we can re-add support for it, if you are willing to test it, because I have no Power4 machines to test on. > Please keep in mind that IBM isn't the sole manufacturer of POWER machines > but there are also people running PPC64 Linux on embedded PPC64 machines > with Freescale CPUs for example. Yes I'm aware of that, I have several Freescale machines which are part of my continuous-integration setup. cheers
