Hi,
I tried runnig L4Linux on fiasco UX but it didn't work. I enabled three options for the L4Linux. (Exception IPC / Inter-task ex-regs syscall / Handle and preserve segments) I have no idea why l4linux causes the trap. Anyone could help me?
Followings are log and disassembling of vmlinux.
Thanks in advance. ------------------------------------------------------------------------------------ $ ./lx con /home/zugwan/boot/fiasco_ux/fiasco -m 256 -symbols /home/zugwan/boot/fiasco_ux/Symbols -lines /home/zugwan/boot/fiasco_ux/Lines -rmgr /home/zugwan/boot/l4bin/rmgr-ux -symbols -lines -sigma0 /home/zugwan/boot/l4bin/sigma0-ux -fb_program /home/zugwan/boot/fiasco_ux/ux_con -irq0 /home/zugwan/boot/fiasco_ux/irq0 -t 32768 -G 640x480@16 -l /home/zugwan/boot/l4bin/names -l /home/zugwan/boot/l4bin/log -l /home/zugwan/boot/l4bin/dm_phys -l /home/zugwan/boot/l4bin/simple_ts -l /home/zugwan/boot/l4bin/fuxfprov -n9 -l /home/zugwan/boot/l4bin/rtc-ux -n10 -l /home/zugwan/boot/l4bin/l4exec -l /home/zugwan/boot/l4bin/con-ux -n12 -l /home/zugwan/boot/l4bin/loader /home/zugwan/boot/l4bin/run /home/zugwan/boot/cfg/l4linux26.ux
