From d12b9ff2a4e21587e5b180008c88a0e6e1ec8ac5 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 23 Feb 2015 11:17:59 -0500 Subject: [PATCH] ide: migrate initial request state via IDEBus This only breaks backwards migration compatibility if the bus is in an error state. It is in principle possible to avoid this by making two subsections (one for version 1, and one for version 2, but with the same name) with different "_needed" callbacks. The v1 callback would return true if error_status != 0 and the bus is PATA; the v2 callback would return true if error_status != 0 and the bus is AHCI. Forward migration keeps working.
