Subject: [Stable-7.2.6 22/37] hw/ppc/e500: fix broken snapshot replay
Date: Sat, 9 Sep 2023 16:04:52 +0300 [thread overview]
Message-ID: <20230909130511.354171-22-mjt@tls.msk.ru> (raw)
In-Reply-To: <qemu-stable-7.2.6-20230909160328@cover.tls.msk.ru>
From: Maksim Kostin <maksim.kostin@ispras.ru>
ppce500_reset_device_tree is registered for system reset, but after
c4b075318eb1 this function rerandomizes rng-seed via
qemu_guest_getrandom_nofail. And when loading a snapshot, it tries to read
EVENT_RANDOM that doesn't exist, so we have an error:
qemu-system-ppc: Missing random event in the replay log
To fix this, use qemu_register_reset_nosnapshotload instead of
qemu_register_reset.
Reported-by: Vitaly Cheptsov <cheptsov@ispras.ru>
Fixes: c4b075318eb1 ("hw/ppc: pass random seed to fdt ")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1634
