Subject: [PATCH v3 0/2] generic and PowerPC accessor functions for arch keystore
Date: Mon,  1 Aug 2022 07:34:24 -0500	[thread overview]
Message-ID: <20220801123426.585801-1-gjoyce@linux.vnet.ibm.com> (raw)

From: Greg Joyce <gjoyce@linux.vnet.ibm.com>

Architectural neutral functions have been defined for accessing
architecture specific variable store. The neutral functions are
defined as weak so that they may be superseded by platform
specific versions.

PowerPC/pseries versions of these functions provide read/write access
to the non-volatile PLPKS data store.

This functionality allows kernel code such as the block SED opal
driver to store authentication keys in a secure permanent store.
