Hi! We're pleased to announce version 1.5 of GNU Mach, the GNU distribution of the Mach microkernel, <http://www.gnu.org/software/hurd/microkernel/mach/gnumach.html>.
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. GNU Mach runs on 32-bit x86 machines. A version running on 64-bit x86 (x86_64) machines is in progress. Volunteers interested in ports to other architectures are sought; please contact us (see below) if you'd like to help. This new release bundles bug fixes and enhancements done since the last release: | Version 1.5 (2015-04-10) | | Numerous cleanups and stylistic fixes of the code base. Several | problems have been identified using static analysis tools and | subsequently been fixed. | | A protected payload can now be associated with capabilities. This | payload is attached by the kernel to delivered messages and can be | used to speed up the object lookup in the receiving task. | | The kernel debugger can now parse ELF symbol tables, can be invoked | over serial lines, gained two new commands and has received usability | improvements. | | The vm pageout policy has been tuned to accommodate modern hardware. | | The kernel gained partial ACPI support on x86, enough to power down | the system. Many thanks to all the people who are helping! Releases may be downloaded from <ftp://ftp.gnu.org/gnu/gnumach/>, or checked out of Git, <http://git.savannah.gnu.org/cgit/hurd/gnumach.git/>.
