Subject: [PATCH v6 17/17] crypto/nx: Register and unregister VAS interface on PowerVM
Date: Thu, 17 Jun 2021 13:39:41 -0700 [thread overview]
Message-ID: <121ea1f4eb3004f3b8f4fe8abefaecc88b292efd.camel@linux.ibm.com> (raw)
In-Reply-To: <827bf56dce09620ebecd8a00a5f97105187a6205.camel@linux.ibm.com>
The user space uses /dev/crypto/nx-gzip interface to setup VAS
windows, create paste mapping and close windows. This patch adds
changes to create/remove this interface with VAS register/unregister
functions on PowerVM platform.
