From 29fd20b8e68a4d31a82909265b1e650b7b860f54 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Javier=20Gonz=C3=A1lez?= Date: Thu, 3 Mar 2016 15:06:41 +0100 Subject: [PATCH] lightnvm: do not load L2P table if not supported MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit An Open-Channel SSD can work on two modes: (i) hybrid mode, where the L2P table is maintained both by the host and by the device; and (ii) full host-based, where the L2P table is uniquely maintained by the host. In the advent of a new target implementing the full host-based mode, do not assume that the L2P table must be loaded on the generic media manager; check device properties loaded on the identify command instead.
