From af9e40aa8f36e30e89f16323b3d341ee59309b7e Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 23 Mar 2015 19:03:13 +0100 Subject: hw: Mark devices picking up block backends actively FIXME MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drives defined with if!=none are for board initialization to wire up. Board code calls drive_get() or similar to find them, and creates devices with their qdev drive properties set accordingly. Except a few devices go on a fishing expedition for a suitable backend instead of exposing a drive property for board code to set: they call driver_get() or drive_get_next() in their realize() or init() method to implicitly connect to the "next" backend with a certain interface type. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is this inconsistent with how the other block device models work (they connect to a backend explicitly identified by a "drive" property), it breaks when the "next" backend has been picked up by the board already. Example: $ qemu-system-arm -S -M connex -pflash flash.img -device ssi-sd Aborted (core dumped) Mark them with suitable FIXME comments.

Board code examines nd_table[] to find them, and creates devices with their qdev NIC properties set accordingly.
