Fernandez Montecelo <manuel.montez...@gmail.com> 收件人: debian-devel-annou...@lists.debian.org Hello dear developers, As you may have noticed, the riscv64 architecture has been promoted in recent days from Debian-ports to the main Debian archive and infrastructure. As the Release Managers mentioned in their recent bits after the release of Bookworm [1], the expectation is to be in a position to ship Trixie with riscv64 support (subject to architecture qualification later in the cycle, as usual). Here are some highlights and a bit of information in a nutshell. For more details, refer to the wiki page [2]. [1] https://lists.debian.org/debian-devel-announce/2023/06/msg00001.html [2] https://wiki.debian.org/RISC-V Bootstrap in progress --------------------- As part of becoming an official architecture, the established procedure is to rebootstrap the port from a minimal set of packages. This process has just started, that's why the sid and experimental suites are almost empty, and many packages that were available before (when in debian-ports) now appear as "BD-Uninstallable" in wanna-build. The build daemons have already started to build packages for the official archive, and on our side we will concentrate on breaking build-dependency loops and fix FTBFS problems of packages in the critical paths. In order to make this process as smooth as possible, we would like to ask you: - Please help us by merging related patches that are available in the BTS promptly. They might not be directly related to riscv64, but can be a more general problem like a FTBFS due to the switch to GCC 13 as the default compiler. - Please do not to disable any features in your packages due to the unavailability of specific build-dependencies in riscv64, they should come back at some point in the next weeks. - Unless explicitly asked by the porters, please refrain from uploading manually built packages to the archive. - In general any help understanding, debugging or fixing riscv64-specific issues are welcome. You might want to use the porterbox for that (see below). During the bootstrap process, the debian-ports archive is still accessible; however, it will no longer receive updates, except (in very few exceptions) if it's to help with the rebootstrapping of the main archive. Build daemons ------------- The current build daemons consist in 9 HiFive Unmatched boards, graciously hosted at OSUOSL [3] and MAN-DA [4]. While this should be sufficient to keep up with the port, we are aware that the build time for some packages is quite important. We are actively working on acquiring next generation RISC-V hardware, it is however challenging to get hardware that matches the requirements [5], especially being supported by the mainline Linux kernel. However, we are optimistic that it will happen before the release of Trixie, and we already have identified a few promising candidates. Once the initial rebootstrap is done, the current build daemons will be handed over to DSA. Until then, the packages are now manually signed, so it's normal if they stay a few hours in "Built" state before getting "Uploaded". [3] https://osuosl.org/ [4] https://www.man-da.de/ [5] https://dsa.debian.org/ports/hardware-requirements/ Porterbox --------- The current porterbox [6] is also based on an HiFive Unmatched board. It is available to Debian Developers to help debugging riscv64 issues. The porterbox includes two sets of chroots: - The chroot for the official archive are called 'sid' and 'experimental' and are regularly updated, however a limited number of packages are currently available. - The original debian-ports archive chroots are called 'sid-dp' and 'experimental-dp', and are no longer updated. However it can still be a valuable resource for debugging issues that were identified before the rebootstrap process started. They will eventually be removed.
