With these patches kvm unit tests are now bootable under LPAR and
z/VM, as well as from KVM disks. Don't forget to convert the ELF files
to binary via:
objcopy -O binary s390x/test.elf test.bin
For this to work we added:
* Initial PSW in lowcore
* Switch to 64 bit and z/Arch
* SCLP linemode console
This is an early version, linemode currently splits lines a bit too
often and I still need to polish comments and cleanup code.
