      1. Are machines available to buy for the general public?
      2. Is full source available?
      3. Is this architecture related to other architectures already in the archive, or that also should be considered, either now or in the future? Can the related architectures be supported in a single architecture (eg, with a biarch arrangement)?
      4. Are there 3 or more developers (or NMs) actively maintaining the port? Who are they?
      5. What sort of architecture is this? Desktop/workstation? Mainframe/supercomputer? Embedded? Something else?
      6. Does it have any users? If a desktop system, are there Debian admins who run Debian systems on the arch? If an embedded system are there real systems shipping that a Debian port will be useful for? If a mainframe system are there real systems with many users that a Debian port will be useful for? Who are they?
      7. Is there kernel and toolchain support? At what level? Are the latest versions supported, or are legacy releases required for compatibility with some hardware?
      8. Has the ABI stabilised, or are there major ABI changes coming up? Is the ABI stable enough to ensure users will be able just "apt-get dist-upgrade" from one version to the next?
      9. How do you install a system? (URL to a HOWTO)
      10. Has a buildd been setup? How much of the archive has been built (count by source package, builds of old versions are fine for this case)?
      11. What hardware is potentially available as a fast buildd?
      12. Is there an example box developers can login to to see if it works?
      13. It's also worth considering whether the port has any special requirements. If the port is mainly for embedded systems, it may be appropriate to have different installation or release arrangements compared to normal desktop/workstation architectures.

Questions for new architectures

Are machines available to buy for the general public?

Yes. You can buy the machines at the market. Two of them are available at the moment:

http://www-03.ibm.com/systems/power/hardware/s812l-s822l/

The data sheet could be IBM Power System S812L and S822L data sheet

Is full source available?

  • Yes. The full stack is open source.
  • Kernel support is already upstream
  • Toolchain (GCC, glibc, gdb, binutils) support is already upstream also

  • Yes; it's related to the ppc64 and powerpc ports, but with a different/newer ABI (ELFv2), and running in little endian mode. A multi-arch arrangement with the other ports is not feasible, since the kernel doesn't support bi-endianness.

Are there 3 or more developers (or NMs) actively maintaining the port? Who are they?

The current development team has neither Debian New Members nor Debian Developers.

https://wiki.debian.org/ppc64el#Development_Team

What sort of architecture is this? Desktop/workstation? Mainframe/supercomputer? Embedded? Something else?

  • Servers. Running in bare metal and on KVM guests

Does it have any users? If a desktop system, are there Debian admins who run Debian systems on the arch? If an embedded system are there real systems shipping that a Debian port will be useful for? If a mainframe system are there real systems with many users that a Debian port will be useful for? Who are they?

  • Yes, there are users -- at this moment, there are 2 or 3 users around.

Is there kernel and toolchain support? At what level? Are the latest versions supported, or are legacy releases required for compatibility with some hardware?

  • Yes. The architecture support started with these versions, which are recent:
  • Linux kernel: 3.13
  • GCC: 4.8
  • glibc: 2.18
  • binutils: 2.24

Has the ABI stabilised, or are there major ABI changes coming up? Is the ABI stable enough to ensure users will be able just "apt-get dist-upgrade" from one version to the next?

How do you install a system? (URL to a HOWTO)

Currently, running debootstrap from another port/architecture and running debootstrap second-stage from the port, or using debian installer.

https://wiki.debian.org/ppc64el

Has a buildd been setup? How much of the archive has been built (count by source package, builds of old versions are fine for this case)?

What hardware is potentially available as a fast buildd?

  • The servers on which this port runs -- they are sufficiently fast for building packages.

Is there an example box developers can login to to see if it works?

It's also worth considering whether the port has any special requirements. If the port is mainly for embedded systems, it may be appropriate to have different installation or release arrangements compared to normal desktop/workstation architectures.

  • No
