Subject: [RFC PATCH v2 02/16] qapi: Implement query-machine-phase QMP command
Date: Wed, 22 Sep 2021 18:13:51 +0200 [thread overview]
Message-ID: <20210922161405.140018-3-damien.hedde@greensocs.com> (raw)
In-Reply-To: <20210922161405.140018-1-damien.hedde@greensocs.com>
From: Mirela Grujic <mirela.grujic@greensocs.com>
The command returns current machine initialization phase.
From now on, the MachineInitPhase enum is generated from the
QAPI schema.
