While we are happy to see that there obviously is quite some interest in +the GNU Hurd, we also saw some rumors and outdated information flowing around. +In the following, we try to clear the situation up a bit. + + * *Debian wants to replace the Linux kernel with the GNU Hurd*. {X} + **Wrong**. We plan to get into Wheezy as an additional port besides + GNU/Linux and GNU/kFreeBSD -- but we don't know whether we will make it. + It mostly depends on a lot of work which is still to be done. If you + want to help, please see our [[contributing]] page and the *to do* list + maintained on <http://wiki.debian.org/Debian_GNU/Hurd>. + We’d be happy to have you on board! + + * *Java support for GNU/Hurd is in the works*. (./) **True**. Jérémie + Koenig is working on making a versatile Java programming environment + available on the GNU/Hurd as part of his [[Google Summer of Code + project|user/jkoenig/java]], focussing on OpenJDK 7. Also, we already do + have support by the GCJ/ECJ platform, but this is not fully functional, and + Jérémie is improving that, too. + + * *GNU/Hurd has no support for X.org*. {X} **Wrong**. X.Org *does* + work, and has for a long time. (Anyone remember + [1998's XFree86](http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xfree86/os-support/hurd/hurd_video.c?rev=1.1&content-type=text/vnd.viewcvs-markup), + by chance?) It is correct however that not a lot of advanced + drivers work, due to missing DRM (Direct Rendering Manager) + support and that it is [[somewhat_unstable|hurd/status]]. + +[[tschwinge]] thinks that the following one is a bit questionable... + + * *The GNU/Hurd only runs on legacy hardware*. {X} **Wrong**. The GNU/Hurd + is only tested on a few platforms, but it likely runs on modern processors. + If you want to see if it works for you, just test a + [[hurd/running/Live_CD]]. + + * *Hurd only supports legacy devices:* ½ Partly True: Currently most + drivers are from Linux 2.0. For network cards, Linux 2.6+ drivers + are available through DDE, though (needs manual setup for + now). With a good amount of work, DDE also allows porting other + classes of drivers to allow using the drivers from recent Linux + releases — and push them into userspace. + + * *The Hurd has no SMP:* <u>✔ **True**</u>: The **Hurd servers + support SMP** and **GNU Mach has SMP support**. But the latter + [[does_not_yet_have_drivers_for_nowadays_chipsets|faq/smp]], so + the Hurd currently can’t take advantage of multiple cores. + + * *Developing a microkernel must be harder than developing a + monolithic kernel, because the Hurd took so long:* ✘ **Wrong**: + For the last decade, the Hurd had on average 5 hobby + developers. That these developers managed to get the Hurd into a + state where it actually gets not too far from the Linux kernel in + performance — which has about 1000 developers, many of them full + time — shows the efficiency of the Hurd’s design. + + * *Installation does not work:* ½ Partly True: Did you read the + [[README|http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/YES_REALLY_README.txt]] + ([[file|http://xkcd.com/293/]])? Just like any beta piece of + software, there are known pitfalls to avoid (or better, help to + fix). You can also simply use the the + [[preinstalled image|http://people.debian.org/~sthibault/hurd-i386/debian-hurd.img.tar.gz]]. + + * *The system is called GNU/GNU Hurd:* ✘ **Wrong**: The GNU userland + (glibc, coreutils, …) and the GNU Hurd together form the GNU + system. To avoid being mistaken for GNU/Linux, we normally use + the name GNU/Hurd or GNU Hurd. The *correct* name is simply GNU. + +**Test results** + +The results of the test from Phoronix were quite good. We expected +that the microkernel design of the Hurd would have a far more severe +performance hit. + +Some possible explanations include: + +* The tests were mostly CPU bound, so the kernel was not that + relevant. +* IPCs [are no more such a problem on recent hardware][ipc]. + +Note: The emulation layer should rather make the context switches + worse, so it’s likely not a reason for the unexpectedly good + performance. + +[ipc]: http://citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.51.16 + +"""]] + +<!-- + +slashdot + +and phoronix did some [performance tests of the Hurd][phorperf], +[phorperf]: http://www.phoronix.com/scan.php?page=article&item=debian_gnu_hurd&num=1 + +--- + +IRC, freenode, #hurd, 2011-08-24: + + < ArneBab> hurd related: I now think you were right, antrik: the hurd + rumors don’t belong into the news (tschwinge) + < antrik> ArneBab: you mean the postscriptum as a whole, or just the wild + rumours part?... + < ArneBab> the whole PS + < ArneBab> it should rather go into a blog post + < ArneBab> (in the wiki) + < antrik> hm...
