Subject: A question about Cortex-A73 erratum 858921
Date: Fri, 9 Sep 2022 15:31:43 +0800	[thread overview]
Message-ID: <cce62c36-c2f4-7e0e-ad6d-6eae98f45aee@huawei.com> (raw)

Hi all,

Recently I am learning the code related to Arm arch timer. I found that the
Cortex-A73 erratum 858921 does not set the corresponding callback functions:
set_next_event_phys and set_next_event_virt like other erratums. Won't it
get the wrong value when reading the counter during setting next event?

Looking forward to your reply.

Thanks,
Kunkun Jiang
