Subject: [kvm-unit-tests PATCH v2 0/6] 390x: Add cross hypervisor and disk boot
Date: Wed, 05 Dec 2018 15:39:12 +0000 [thread overview]
Message-ID: <20181205153918.29480-1-frankja@linux.ibm.com> (raw)
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.
v2:
* Moved cleanup to the front and broadened patch
* Split up SCLP patch into interrupt and linemode
* Removed unneeded instructions
* Improved comments and commit messages
Janosch Frank (6):
s390x: Cleanup sclp-ascii.c and add sigp order definitions
s390x: Make tests bootable from disk
s390x: Switch to z/Arch if needed
s390x: Add BSS clearing for non ELF boot
s390x: Use interrupts in SCLP
s390x: Add linemode console
