We basically implement the real hardware ipl procedure. This allows for booting Linux guests on vfio-ccw devices. vfio-ccw's channel program prefetch algorithm complicates ipl because most ipl channel programs dynamically modify themselves. Details on the ipl process and how we worked around this issue can be found in docs/devel/s390-dasd-ipl.txt. Changelog ========== v6 - Added patch #16 to fix regression whereby we attempted to boot from console devices when no default boot device was specified. - Bug fix: Referencing a byte past end of sense data status array - Reorganized patch order slightly - Other misc wording/spelling fixups Jason J.
