From b2fc59aaf90f3a0b6e1976d27ce533b035a40b49 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 27 Feb 2017 15:29:21 +0100 Subject: ppc/xics: extend the QOM interface to handle ICPs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let's add two new handlers for ICPs. One is to get an ICP object from a server number and a second is to resend the irqs when needed. The icp_resend() handler is a temporary workaround needed by the ics-simple post_load() handler. It will be removed when the post_load portion can be done at the machine level.
