Subject: [PATCH 02/12] nvme: move OPAL setup from PCIe to core
Date: Tue, 8 Nov 2022 16:02:42 +0100 [thread overview]
Message-ID: <20221108150252.2123727-3-hch@lst.de> (raw)
In-Reply-To: <20221108150252.2123727-1-hch@lst.de>
Nothing about the TCG Opal support is PCIe transport specific, so move it
to the core code. For this nvme_init_ctrl_finish grows a new
was_suspended argument that allows the transport driver to tell the OPAL
code if the controller came out of a suspend cycle.
