-[[!meta title="Doing a GNU/Hurd System Port"]]
-
-How difficult is it to port the GNU/Hurd system to run on another architecture?
-
-The GNU/Hurd system consists of [[/Hurd]] servers running as user-space
-processes on top of the [[GNU Mach|microkernel/mach/gnumach]] microkernel. The
-system functionality is usually accessed through the
-[[POSIX|posix_compatibility]] interface that is provided by [[/glibc]] and
-[[/libpthread]].
-
-A whole-system port involves touching all these components, with varying
-degree, of course.
-
-For a CPU architecture port, the microkernel is the most involved part,
-followed by glibc and the threading library.
-
-The original [[microkernel/Mach]] microkernel was portable to a number of
-architectures which were a lot more popular at the beginning of the 1990s than
-they are now.
-
-The GNU/Hurd system is currently available for the x86 architecture. This
-includes emulators such as [[hurd/running/QEMU]] (or KVM), or
-[[hurd/running/VirtualBox]]. Besides this, there is a port for the [[Xen
-domU|microkernel/mach/gnumach/ports/xen]] *sub-architecture*.
-
-Further on, there are some [[unfinished porting
-attempts|microkernel/mach/gnumach/ports]] for the Alpha, MIPS and PowerPC
-architectures. These have not been completed due to little developer interest.
-
-Another option is to do the port at a different layer: port the Hurd servers to
-not run on the GNU Mach microkernel, but instead on top of [[another
-microkernel|which_microkernel]]. Or, even by providing a Mach emulation layer
-on top of a monolithic kernel. For example, there could be a port for [[having
-Mach run as a POSIX user-space process|open_issues/mach_on_top_of_posix]], or
-by implementing the [[Mach IPC|microkernel/mach/ipc]] facility (as well as
-several others) as Linux kernel modules. While there have been some
-experiments, no such port has been completed yet.
