user-level port
by Andreas Rottmann 27 Jun '02

27 Jun '02

Hi! I hope this is the right place to ask. (If not, please point me there ;-)) I have read on the Fiasco homepage that Fiasco is beeing/was ported to run as a user-level process under Unix. What is the state of this project? And what is the mentioned CVS branch? However, I am interested in this. A nice way to go would be to port Fiasco to a386 (http://a386.nocrew.org/), IMO. I don't know if I can be of any help, since I haven't (yet) done much kernel-level hacking...

Hello folks, First of all I'd like to thank you for such a development environment: linux over L4. After some time reading the faq and the mail list I could make it work. But now some questions: 1) Is X Window System still not running under l4linux ? I got: sys_iopl() called (8 times) "XF86_SVGA" (22.00) raised page fault (error =04) at 000000004 (vm_area can't grow down). 2) I'd like to run "kernel debugger" after l4linux boots (just for fun). Kernel debugger manual says that I could by pressing ESC but when I try, my system halts. 3) It seems that command "halt" doesn't work. It goes till "unmounting local file systems" and stops. "CTRL ALT DEL" still works. Thanks in advance. Luís Alberto Lucas lalucas(a)cefetpr.br

At UNSW we had a SCSI > driver running on L4/MIPS, what's the status of that? Btw, you should not forget that we also have a quite rich set of drivers running within a POSIX emulation layer -- L4Linux. Also 100% correct and I'm definitely no mathematician ;) - Volkmar

dear l4-hackers does any version of L4 have an adaptec SCSI driver? we are trying to add an adaptec 2940UW SCSI driver to the Sombrero Single Address Space OS I have taught L4 as the topic of my OS internals course (using the L4 version available from UNSW) - but can't find such a driver in that source thanks for any info you have on this don miller -- Donald S.
