quick update before I snooze and lose

Filed under: Uncategorized — Muli Ben-Yehuda @ 2:42 AM

Had one of those days that make me wish I could get better acquainted with every nearby computer, preferably with a chainsaw. I spent 7.5 hours(!) trying to get 2.6.1 to boot on a thinkpad running Fedora Core I with the root file system on an LVM volume. Eventually, it did.

The rest of the day was spent alternatively writing code and slides, for the “Introduction to Linux Device Drivers” talk. I can’t say I’m too thrilled with the way it turned out, but hopefully, it will do. The code, klife-0.02, is available here. It’s does mmap and hooking into the timer interrupt, but the races are abundant. To be cleaned up after I get some sleep (or maybe left as an exercise to the readers ;-))

Quick catchup time:
da_x announced coLinux which he’s been telling me about for a while now and the reception was terrific. Well done, da_x!
– UML with 2.6 woes (posted earlier) were solved thanks to the nice guys on #uml. Turns out that UML does not play well with exec-shield, which FC1 comes with. Running ‘i386 ./linux …’ instead of plain ‘./linux’ allows it to run. No idea what the i386 utility does yet, but disabling exec-shield seems like a pretty safe bet.
– I could swear there was more I needed to write about, but I can’t remember what.


  1. I don’t seem to have i386, could it be a RH/FC1 specific?

    • It’s part of the ‘setarch’ or ‘setarchs’ package. I think it’s Fedora specific, but don’t really know. Haven’t had time to look into it yet..

  2. Thanks
    Yes, a lot of people got very excited about coLinux. I’m still waiting for your participation in development. I have some ideas about changing the interrupt model and other things, I’d like to know your opinions about it.
    Perhaps you can contribute even more, after that Windows kernel driver lecture ;).
