This kernel commit is requested to be included into the bionic's 4.15.0 LTS kernel:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=03aa047ef2db4985e444af6ee1c1dd084ad9fb4c
s390/early: improve machine detection
Right now the early machine detection code check stsi 3.2.2 for "KVM"
and set MACHINE_IS_VM if this is different. As the console detection
uses diagnose 8 if MACHINE_IS_VM returns true this will crash Linux
early for any non z/VM system that sets a different value than KVM.
So instead of assuming z/VM, do not set any of MACHINE_IS_LPAR,
MACHINE_IS_VM, or MACHINE_IS_KVM.
This is required for a dedicated SSC exploiter |
== Justification ==
The s390x early machine detection code check will set all the uknown
hypervisors to z/VM, this will cause crash for any non KVM, z/VM
system.
== Fixes ==
03aa047e (s390/early: improve machine detection)
Patch can be cherry-picked into Bionic kernel.
Instead of setting all the other hypervisors to z/VM, it will only set
MACHINE_FLAG_VM if it matches the case.
== Tests ==
A test kernel could be found here:
https://people.canonical.com/~phlin/kernel/lp-1829972-s390x-early/
Boot tested on a s390x KVM node and verified by IBM as well.
== Regression Potential ==
Low, this just improves the detection logic and the changes are
specific to s390x.
== Original Bug Report ==
