This patch move timer_new from init into realize to fix it. Reported-by: Euler Robot Signed-off-by: Pan Nengyuan --- Cc: Laurent Vivier Cc: Mark Cave-Ayland Cc: David Gibson Cc: qemu-ppc@nongnu.org --- v2->v1: - no changes in this patch. v3->v2: - remove null check in reset, and add calls to mos6522_realize() in mac_via_realize to make this move to be valid. v4->v3: - split patch into two, this patch fix the memleaks. v5->v4: - No change in this patch. But add [patch 3/4] to fix SEGVs during make check-qtest-ppc64 if apply this patch. This patch also depend to another fix [patch 2/4]. --- hw/misc/mos6522.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/hw/misc/mos6522.c b/hw/misc/mos6522.c index 19e154b870..c1cd154a84 100644 --- a/hw/misc/mos6522.c +++ b/hw/misc/mos6522.c @@ -485,6 +485,11 @@ static void mos6522_init(Object *obj) for (i = 0; i < ARRAY_SIZE(s->timers); i++) { s->timers[i].index = i; } +} + +static void mos6522_realize(DeviceState *dev, Error **errp) +{ + MOS6522State *s = MOS6522(dev); s->timers[0].timer = timer_new_ns(QEMU_CLOCK_VIRTUAL, mos6522_timer1, s); s->timers[1].timer = timer_new_ns(QEMU_CLOCK_VIRTUAL, mos6522_timer2, s); @@ -502,6 +507,7 @@ static void mos6522_class_init(ObjectClass *oc, void *data) dc->reset = mos6522_reset; dc->vmsd = &vmstate_mos6522; + dc->realize = mos6522_realize; device_class_set_props(dc, mos6522_properties); mdc->parent_reset = dc->reset; mdc->set_sr_int = mos6522_set_sr_int;
