[RFC PATCH v3 0/2] s390x: Improvements to SIGP handling [QEMU]

Posted by Eric Farman 2 years, 6 months ago

Here is an update to the SIGP handling series, to correspond to
version 3 of the KVM series [1].

The main changes here from v2 are the simplified use of
s390_cpu_reset_sigp_busy() throughout the SIGP handlers,
a new invocation of it from s390_cpu_reset(), and the
implementation of the "set sigp busy" IOCTL.
