Running and using Fiasco and L4Re components

• Systems to use
  • hardware requirements
  • virtual machines
    • QEmu
    • Fiasco-UX
    • VMware
    • Virtualbox
  • Boot from CD
  • Boot from TFTP server
• serial console
• Booting
  • GRUB
    • building patched grub
    • menu.lst
      • menu.lst-Examples
    • Enhanced GRUB1 patches
      • This grub1 version is maintained. You can send patches.
    • GRUB2
  • Images
    • Call 'make help' in the l4/ root directory to get a listing of possible image generation targets
    • See l4/conf/Makeconf.boot.example for more information on customization
    • u-boot:
      • Call 'make uimage E=entry' to generate an uImage
      • Load into u-boot (tftpboot, usb-stick, flash, ...)
      • bootm ....
    • ELF images: make elfimage E=name
      • loadable with any loader that understand ELF (including GRUB, Lauterbach, ARM RVDS, QEmu)
    • Raw images: make rawimage E=name
      • copy into RAM at the start address, set PC to start address and run
      • On ARM the images relocate itself to their linked address, i.e. they can be put anywhere in RAM (copying them to the right place will make booting faster of course).
  • Qemu
    • Go to obj-dir root
    • Call 'make qemu E=entry'
    • For Qemu customization (esp. on ARM) see l4/conf/Makeconf.boot.example and add options to your l4/conf/Makeconf.boot
  • Virtualbox
    • Go to obj-dir root
    • Call 'make vbox E=entry'
    • You need a configuration virtual machine in vbox for that to work. Check l4/conf/Makeconf.boot.example to see how to configuration vbox specifics.
  • You may omit the E=entry which will present you a menu to choose the entry to generate/start from.

Miscellaneous How-Tos

• stacking colorgcc, ccache, distcc, and gcc

Old L4Env Components

• Dice IDL compiler
• L4Env
