I talked to Ryan about the mips port about two weeks ago; I'll try to summarize the information he gave me. The kernel problem you refer to is that the kernel does not use the secondary cache of the chips. Another problem is that one machine (hosted by Flo in Germany) only has 64 MB RAM. Apparently, Flo has more RAM, though; otherwise, I have recently been given some RAM which I'll send him once I'll be back in Europe (in December). The major problem why mips is not keeping up, however, is that the hard drive of a build machine in the States died recently. Unfortunately, this machine is much faster than the other machines in use. I am trying to get a new hard drive for this machine, but unfortunately the hardware donations manager is currently on vacation and hasn't responded to my mail yet; we might just buy one if he doesn't respond soon. Alternatively, in anyone is reading this who can spare a SCSI disk (in the States, for an Indy, see http://sgistuff.g-lenerz.de/machines/indy.html), please get in contact. This would help to improve the situation drastically. > Everything went well with that machine - until we directed the > request to debian-admin to get wanna-build access for mips.

Also, I have been in contact with SGI to get a very powerful system which should solve this problem for a long time. However, I am still working on this. I also offered Ryan to get a temporary system online, but he told me not to bother unless it's a very high performance system. IIUC, it takes some time to get it set up as a buildd, etc. In any case, your offer is welcome, and I think we can make use of it, albeit in a different way. You could make the box available to various Debian people. For example, the XFree86 maintainer is looking for someone to try building the current version in experimental on mips. That would be a great way your machine could be used. In any case, the situation is known and solutions are being worked on. Help is definitely appreciated. Also, while we are covering this topic, let me mention that mips is not a "door stop" architecture. While most machines which were _very_ powerful in the past are fairly dated now (e.g. SGI Indy), mips CPUs are actively being developed.

A m68k has indicated that your machine is helpful for the m68k port, so I urge you to reconsider this decision. -- Martin Michlmayr [EMAIL PROTECTED]
