Subject: [PATCH v1 2/9] ArmPkg: PCD to select conduit for monitor calls
Date: Thu, 30 Sep 2021 16:40:37 +0100 [thread overview]
Message-ID: <20210930154044.37336-3-sami.mujawar@arm.com> (raw)
In-Reply-To: <20210930154044.37336-1-sami.mujawar@arm.com>
Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668)
Define a PCD 'PcdMonitorConduitHvc' to select the conduit to use for
monitor calls. PcdMonitorConduitHvc is defined as FALSE by default,
meaning the SMC conduit is enabled as default.
Adding PcdMonitorConduitHvc allows selection of HVC conduit to be used
by virtual firmware implementations.
