Subject: [kvm-unit-tests PATCH v2 0/6] s390x: Add multiboot and smp
Date: Thu, 5 Sep 2019 12:39:45 +0200 [thread overview]
Message-ID: <20190905103951.36522-1-frankja@linux.ibm.com> (raw)
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.
v2:
* Fixed cr0 masks
* Replaced gotos with loops
* Addressed other review comments
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
