Subject: [patch 03/16] PS3: Add ps3_repository_find_device_by_id()
Date: Fri, 18 Jan 2008 12:30:27 -0800 [thread overview]
Message-ID: <47910C63.4080800@am.sony.com> (raw)
In-Reply-To: <20080118202612.422185192@am.sony.com>
From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom•com>
The storage probe feature of the PS3 hypervisor returns device IDs. Add
the corresponding repository routine ps3_repository_find_device_by_id()
which can be used to retrieve the device info from the repository.
