I cannot speak to ppc64. ppc64el is useful as I'm told POWER can be competitive to Intel/AMD-based services. But I don't know how many users would run Debian. For s390x, IBM does not publicly admit that there are people running Debian, but there are a few. Almost all of them turn popcon off - most of the VMs can't talk to the internet. Of course I don't know if the availability of Ubuntu significantly changed that. They were able to invest much more time into polishing the port and most people just want some kind of Debian derivative. Historically the base system has been very well maintained by IBM, though. So the effort to keep it running has been relatively small. This recently changed somewhat, given that the primary focus is on enterprise distributions, in that stuff like Javascript interpreters don't work well. Essentially it boils down to server workloads that companies need to run, so as Docker and Go became popular, IBM implemented support for it. The same happened for v8 as used by Node. OpenJDK 9 finally comes with a JIT, so you don't have to use IBM Java anymore. And to IBM's credit, they even contributed some bits back to d-i. Although some of those still await testing and merging. The Ubuntu changes did not flow back / were not mergable as-is into Debian. It's always a tradeoff between how much work is necessary to keep the port alive and how many people use it. As long as the port keeps itself working, that's sort of fine in my experience. Once you need to sheperd a lot of things that all break (like the MIPSens historically had to, even working around broken CPUs) or need to deal with 2 GB virtual address space or don't have modern languages like Go or Rust around, it quickly approaches the point where it's not worth it anymore.

The 32-bit MIPS architectures have this limitation which causes various build issues up to the point that maintainers have to reduce optimization levels for the C/C++ compiler to be able to build a package. Another issue is that the Rust compiler, despite being fully supported on 32-bit MIPS, cannot be built natively there because the build process runs out of memory at some point. >> I have seen IBM people on multiple occasions in various upstream >> projects trying to remove code for older POWER targets because >> they insisted anything below POWER8 is not supported anymore.

But in the case of Golang, the necessary extra code paths are really manageable. In fact, have my own tree of Golang where I reverted the changes which dropped POWER5 support and I keep rebasing this tree from time to time and it still works fine. It does work without problems on the x86 side with the kernel and the toolchain still supporting rather old hardware. POWER5 isn't that old. > But it has very awkward implications on the people that still have that > hardware for one reason or another and don't actually rely on a support > contract. My main argument is that if there are still a reasonable amount of users and there are still enough people to help maintain a port, it should not removed just because it's old. In the end, software is written to be useful to users and not for the sake of the people writing it. > For s390x I can say that the port was driven without any commercial > interest on both Aurelien's and my side The question is though: Is there quantifiable amount of users that is running Debian on such big iron instead of one of the Linux enterprise distributions on the market? If the argument is about maintenance burden, then does it justify to support Debian on s390x when the number of users is small? And, if yes, why does that not apply to ppc64, for example?

Essentially they end up actively removing support for anything they don't support anymore. To some degree I understand this behavior: It's a real relieve to not need to support something old and crufty when you're the engineer on the other side having to do that. Even when such support is contributed, someone needs to keep it working and they won't keep old hardware around for that. But it has very awkward implications on the people that still have that hardware for one reason or another and don't actually rely on a support contract. For s390x I can say that the port was driven without any commercial interest on both Aurelien's and my side. Kind regards Philipp Kern

It's been a long time since Debian could run infrastructure on donated hardware. We need hardware that is reliable and that can be quickly replaced when (not if) it fails. So commercial availability is, and should continue to be, a release qualification. It is also unacceptable that the release of an urgent security update should have to wait a long time for builds.

Yes, this is being worked on. There are FPGA-based implementations which allow to boost Amiga and Atari hardware to considerably higher speeds. It's not done on a large commercial scale, so things take longer to develop. But people are working on it and bugs get fixed, code maintained and drivers added. >> * powerpc/ppc64: maintained mostly by IBM people > > IBM looks after 64-bit configurations, so ppc64 is covered but not > powerpc. Well, I have had people from IBM fix 32-bit PowerPC code.

What Oracle is really doing and planning isn't really clear. I have talked to multiple people at Oracle directly and the consensus is that there isn't a consensus what is going to happen next. But again, this just supports my point that the decisions which ports become release architectures is mostly driven by commercial interests and not whether there are users in the community.

I think the problem that I have is that the release qualifications are not practical in the sense that they don't necessarily meet our users expectations. As I said, I think a tier-based system would be more practical as it would allow ports to be degraded more gracefully instead of just kicking them out like it was done with 32-Bit PowerPC. I don't have a proper concept yet, but I think the OBS approach is more versatile, for example. Adrian -- .''`.

But when I see that we have ports as release architectures with hardware where atomics in hardware don't even work correctly and the virtual address space is limited to 2 GiB per process while on the other hand perfectly healthy and maintained ports like powerpc and ppc64 which have actually a measurable userbase and interest in the community are axed or barred from being a release architecture, then I have my doubts that those decisions aren't also driven by commercial interests or politics.

But if stuff that gets removed despite people using it and despite others maintaining it, I am having my doubts. And it has happened more than once where I had to explain users why there aren't any stable releases anymore they can install on their PowerPC-based machines. I really do not mean to accuse anyone of malevolence, I am merely speaking from my personal observations that sometimes such decisions do not necessarily meet the expectations of our users and that there might be a path for improvement, e.g in the form of support tiers like they exist in NetBSD.

Re: Re-evaluating architecture inclusion in unstable/experimental
Hello! I just saw this mail this morning by accident while browsing the archives, I am not subscribed to debian-devel. > The ftpmaster team would like to clarify which Debian ports should and/or would like to continue to be part of Debian unstable and experimental. I'm not sure what context you are referring to? Are you talking about architectures that are present in the main archive or do you also include Debian Ports which has its own FTP server and buildds maintained outside DSA? > As outlined on the Debian Archive Criteria page[0], the key points to consider are whether the architecture has been part of a stable release, whether it is *likely* to be part of a stable release, as well as whether it currently has a sensible number of active maintainers. All ports in Debian Ports have at least one maintainer otherwise it wouldn't be possible to keep the pace with unstable. Furthermore, several of the ports are in very healthy condition and even surpass some release architectures. The powerpc and ppc64 ports, for example, build more packages than any of the mips* ports. As for the kernel maintenance, except for Alpha, all the ports have at least one kernel maintainer: * hppa: actively maintained by two people who also maintain the toolchain * ia64: maintained by one paid developer at Intel * m68k: maintained by multiple independent kernel maintainers, at least five people involved upstream; port is also getting new drivers * powerpc/ppc64: maintained mostly by IBM people * sh4: maintained by two kernel maintainers * sparc64: used to be maintained by a team at Oracle but Oracle recently changed their mind about Linux on SPARC; now it's back to David Miller and some additional volunteers * x32: maintained by the people who maintain the x86 port of the kernel > Whilst you may be happy to continue the work of maintaining the port regardless, don't forget that excess or otherwise unnecessary architectures involve a shared maintenance burden as well as incurring non-trivial requirements on mirror/Debian resources. Debian Ports has its own mirrors. Besides, I think one of the main selling points of Debian is its portability. If we take away this feature, we become less attractive. If the maintenance burden is too high, it might be an idea to switch to a more flexible and powerful infrastructure like SUSE's OBS which makes handling of new ports much easier. It's very easy to set up your own OBS, so people within SUSE do that to maintain their own ports, for example. > The statistics and graphs available on the debian-ports page[1] may provide some objective statistics or reflection on the actual suitability of your architecture's continued inclusion. Jepp. And as you can see, several ports that are thought to be dead long time ago are healthier than some of the official Debian release architectures simply because there are huge communities behind it. The m68k port has a very strong and enthusiastic community which is why the port has already survived multiple other architectures in the kernel like TileGX and similar. There are people building new m68k hardware, writing new drivers and there is even an ongoing effort to create an m68k backend for LLVM so that we can eventually even start building Rust packages (I have already added partial target support for m68k in a local Rust branch). So, it's not always a purely technical decision whether a port remains a release architecture. It's also often highly political and somehow also influenced by commercial entities. Although I think Debian, being a community distribution, should be more oriented towards its community and not towards commercial interests. > So, in the first instance, would you like to continue being part of unstable/experimental? All Debian Ports architectures [1] should remain part of unstable and experimental and are very actively maintained by the Debian Ports team. You can find us in #debian-ports on OFTC.

Re: Re-evaluating architecture inclusion in unstable/experimental
Hi, With my debian-ports hat on, let me answer the parts related to that. First of all as a reminder, debian-ports was originally just there to help bootstrapping an architecture and prove it meets the ftpmasters criteria to become an official architecture. It has been used that way for example for armel, armhf, arm64, kfreebsd-amd64, kfreebsd-i386 and s390x.

I agree for the mirroring part, that's why there are very few debian-ports mirrors (the original plan was even to have none of them) and that it is served through the deb.debian.org CDN. Besides that mirroring aspect, I agree moving an architecture from the official to the debian-ports archive is just moving the load to a different set of Debian person and different set of Debian hardware.

For my part, I was not talking about that patch, but about the hurd-related patches. For others, I can simply quote what was said: Felix Geyer wrote: > I suggest that instead you respond to questions on bugs you opened. > I'm not interested in maintaining patches for things that clearly > belong upstream.

I'm sorry Samuel, I asked both you and James Clarke, Cc:ed, for help on this issue and you both said it was not possible to NMU cmake, even if you are both DD's. See bugs https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=905140 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900240 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=905138 I think that the power of a package maintainer is far too big, making it possible to reject/ignore important and other bugs, especially with patches, for non-released architectures (and effectively block NMUs). I think the next step would be to bring the responsibilities and commitments of a Package Maintainer to the TC, in addition to the full control of everything related to that package. Maybe the recent salvaging of packages could be helpful in the future regarding this problem.

If it's not tricky, a NMU should be able to fix it easily. Samuel

Correct: One example is cmake for both hurd-i386 and kfreebsd-any. It does not even have to be tricky. For kfreebsd the patch(es) is attached below!

Hello, Luke W Faraone, le lun. 27 août 2018 00:33:58 -0700, a ecrit: > So, in the first instance, would you like to continue being part of > unstable/experimental? Well, I can simply point at what we said last time (IIRC) the question was raised, here are the importants point we see in being on debian instead of debian-ports: https://lists.debian.org/debian-devel/2015/05/msg00070.html Samuel Thibault wrote for the debian-hurd team: > * Appearing on packages' and maintainers' PTS > pages like http://buildd.debian.org/bash and > https://buildd.debian.org/sthiba...@debian.org This has been changed since then: debian-ports architectures show up there. > * Getting binNMUs from d-release transitions I believe this is also now done for debian-ports architectures?

Considering how even quite a few Linux architectures ports are not making it, I don't think we could say it likely that hurd-i386 be part of a stable release. > Whilst you may be happy to continue the work of maintaining the port > regardless, don't forget that excess or otherwise unnecessary > architectures involve a shared maintenance burden as well as incurring > non-trivial requirements on mirror/Debian resources. Concerning mirroring, it is indeed useless to mirror hurd-i386 worldwide. Considering maintenance burden, I'm a bit afraid of here simply moving the load from the ftpmaster team to the debian-ports ftpmaster team. I don't know the details, so can't say, I'm just Cc-ing both teams. > The statistics and graphs available on the debian-ports page[1] may > provide some objective statistics or reflection on the actual > suitability of your architecture's continued inclusion. > [1]: https://buildd.debian.org/stats/ Such statistics are really difficult to get any real conclusion from. Sometimes 10% packages are missing just for one tricky nonLinux-specific issue in one package. Samuel
