[kvm-unit-tests PATCH v3 0/6] s390x: Add multiboot and smp

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Cross testing emulated instructions has in the past brought up some
issues on all available IBM Z hypervisors. So let's upstream the last
part of multiboot: sclp interrupts and line mode console.

SMP tests are a great way to excercise external interruptions, cpu
resets and sigp. The smp library is always initialized and provides
very rudimentary CPU management for now.

v3:
 * Simplified linemode buffering
 * Removed error constant use
 * Smaller fixes

Janosch Frank (6):
  s390x: Use interrupts in SCLP and add locking
  s390x: Add linemode console
  s390x: Add linemode buffer to fix newline on every print
  s390x: Add initial smp code
  s390x: Prepare for external calls
  s390x: SMP test
