He +writes: + + MIG seems to just work (thanks to all of Flávio's work!).

He +wrote: + + Last time, there was no AArch64 port of GNU Mach, and so the only testing + I have done was running a simple statically-linked executable on Linux under + GDB, which, nevertheless, helped me identify and fix a number of issues. + + Since then, however, I have been (some may say, relentlessly) working on + filling in the missing piece, namely porting GNU Mach (with important help & + contributions by Luca D.). I am happy to report that we now have an + experimental port of GNU Mach that builds and works on AArch64! While that may + sound impressive, note that various things about it are in an extremely basic, + proof-of-concept state rather than being seriously production-ready; and also + that Mach is a small kernel (indeed, a microkernel), and it was designed from + the start (back in the 80s) to be portable, so most of the "buisness logic" + functionality (virtual memory, IPC, tasks/threads/scheduler) is explicitly + arch-independent. + + Despite the scary "WIP proof-of-concept" status, there is enough + functionality in Mach to run userland code, handle exceptions and + syscalls, interact with the MMU to implement all the expected virtual + memory semantics, schedule/switch tasks and threads, and so on. + Moreover, all of GNU Mach's userspace self-tests pass! + + This meant there was enough things in place for me to try running + glibc on it, and the amazing thing is my simple test executable, the + same one I previously tested on Linux with GDB, just worked on real + Mach without me having to make any additional changes to the glibc + side, or even recompile it. + + But I did not stop there, and I got several of the core Hurd servers + working! Namely, these are ext2fs, exec, startup, auth, and proc + servers. All of them but ext2fs are dynamically linked; ld + aarch64.so.1 sucessfully locates and maps the programs themselves + and their required dependencies, and Mach pages in code and data + pages from ext2fs as they are accessed, transparently to the + program, just as one would expect it to. + + +Be sure to read more from his announcement +[email](https://lists.gnu.org/archive/html/bug-hurd/2024-03/msg00114.html). + +Sergey also announced [a new Alpine distro based on Hurd](https://lists.gnu.org/archive/html/bug-hurd/2024-01/msg00180.html) (it +currently does not have a name). His goal is to add another Hurd distribution, +which will force the Hurd to work with different software and hopefully fix more +bugs. Alpine Linux also usually runs the latest software, so this new Hurd +distribution will be for those who like living on the bleeding edge. He writes: + + + I have ported many Alpine packages to build with (i386, for now) GNU + Mach, the Hurd, and glibc, replacing Linux and musl. If you want a + specific number: as of yesterday, I have 299 installable packages; the + number of source packages is of course several times less than that. + Still, this includes things like curl, ncurses, nano, native binutils + & gcc & mig, libffi, openrc, openssl, util-linux, busybox, apk-tools, + ... and of course gnumach, hurd (with dependencies like libdaemon, + parted, ...), and glibc. Importantly, all this cleanly bootstraps + using the scripts/bootstrap.sh script that they provide; this is too + somewhat like Flávio's scripts, but it uses the real full Alpine + package definitions for e.g. GCC (patched by me for glibc / Hurd + support). + + Above the kernel and libc, things remain much as they were in upstream + Alpine: the system boots (will boot — I haven't tried it yet) with + busybox init & OpenRC, and uses busybox as its basic userland. GNU + software such as Bash is installable, too. + + +This new Hurd distribution currently does not have a mailing list, irc room, or +website. If you are interesting +in helping Sergei to develop it further, then please email bug-hurd@gnu.org. + +Luca Dariz added [userspace +tests](https://lists.gnu.org/archive/html/bug-hurd/2024-01/msg00125.html), which +work with qemu. We currently test the Hurd in qemu on a GNU/Linux host. He also described how [he currently uses the 64-bit +Hurd](https://lists.gnu.org/archive/html/bug-hurd/2024-01/msg00047.html). +Perhaps you should follow that advice if you want to try running a 64-bit Hurd +on qemu. + +Manolo de Medici made a WIP patch series that gets [qemu +to run on the +Hurd](https://lists.gnu.org/archive/html/bug-hurd/2024-01/msg00153.html). + +I organized a belated GNU/Hurd Christmas party. We had 6 or 7 +attenders, which was pretty awesome! I was not able to record the event, so +perhaps we should try for another meet perhaps at the end of Q2. If you would +like to help me plan/organize/join such a party, then please email +bug-hurd@gnu.org. + +If you want to test if your favorite packages work on the Hurd and +contribute towards making the full GNU system usable for a wider range +of people, please [[check the contributing page|contributing]]. + +--- + +The **GNU Hurd** is the GNU project's replacement for the Unix kernel. It is a +collection of servers that run on the Mach microkernel to implement file +systems, network protocols, file access control, and other features that are +implemented by the Unix kernel or similar kernels (such as Linux). [[More +detailed|hurd/documentation]]. + +**GNU Mach** is the microkernel upon which a GNU Hurd system is based. It +provides an Inter Process Communication (IPC) mechanism that the Hurd uses to +define interfaces for implementing in a distributed multi-server fashion the +services a traditional operating system kernel provides.
