Subject: [PATCH v2 1/5] s390x: Don't do a normal reset on the initial cpu
Date: Fri, 22 Nov 2019 08:59:58 -0500 [thread overview]
Message-ID: <20191122140002.42972-2-frankja@linux.ibm.com> (raw)
In-Reply-To: <20191122140002.42972-1-frankja@linux.ibm.com>
The initiating cpu needs to be reset with an initial reset. While
doing a normal reset followed by a initial reset is not wron per-se,
the Ultravisor will only allow the correct reset to be performed.
