Subject: [PATCH 3/6] ppc/pef.c: initialize cgs->ready in kvmppc_svm_init()
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-MergeRequest: 22: Synchronize with RHEL-AV 8.5 release 23 to RHEL 9
RH-Commit: [2/5] b204f898d2333686e30b14c050ac7a9289670f23 (mrezanin/centos-src-qemu-kvm)
RH-Bugzilla: 1957194
QEMU is failing to launch a CGS pSeries guest in a host that has PEF
support:
qemu-system-ppc64: ../softmmu/vl.c:2585: qemu_machine_creation_done: Assertion `machine->cgs->ready' failed.
Aborted
This is happening because we're not setting the cgs->ready flag that is
asserted in qemu_machine_creation_done() during machine start.
cgs->ready is set in s390_pv_kvm_init() and sev_kvm_init(). Let's set it
in kvmppc_svm_init() as well.
