But unfortunately this still requires care :-\
qemu-system-ppc64: cap-xive higher level (1) in incoming stream than on
destination (0)
qemu-system-ppc64: error while loading state for instance 0x0 of device 'spapr'
qemu-system-ppc64: load of migration failed: Invalid argument
or
qemu-system-ppc64: cap-xics higher level (1) in incoming stream than on
destination (0)
qemu-system-ppc64: error while loading state for instance 0x0 of device 'spapr'
qemu-system-ppc64: load of migration failed: Invalid argument
when migrating from QEMU 4.1 with ic-mode=xics and ic-mode=xive respectively.
This happens because the existing pseries-4.1 machine type doesn't send the
new caps and the logic in spapr_caps_post_migration() wrongly assumes that
the source has both caps set:
srccaps = default_caps_with_cpu(spapr, MACHINE(spapr)->cpu_type);
for (i = 0; i < SPAPR_CAP_NUM; i++) {
/* If not default value then assume came in with the migration */
if (spapr->mig.caps[i] != spapr->def.caps[i]) {
spapr->mig.caps[SPAPR_CAP_XICS] = 0
spapr->mig.caps[SPAPR_CAP_XIVE] = 0
srccaps.caps[i] = spapr->mig.caps[i];
srcaps.caps[SPAPR_CAP_XICS] = 1
srcaps.caps[SPAPR_CAP_XIVE] = 1
}
}
and breaks
for (i = 0; i < SPAPR_CAP_NUM; i++) {
SpaprCapabilityInfo *info = &capability_table[i];
if (srccaps.caps[i] > dstcaps.caps[i]) {
srcaps.caps[SPAPR_CAP_XICS] = 0 when ic-mode=xive
srcaps.caps[SPAPR_CAP_XIVE] = 0 when ic-mode=xics
error_report("cap-%s higher level (%d) in incoming stream than on
destination (%d)",
info->name, srccaps.caps[i], dstcaps.caps[i]);
ok = false;
}
Maybe we shouldn't check capabilities that we know the source
isn't supposed to send, eg. by having a smc->max_cap ?
