From 51b180051e366c69b018af05c412b72282294d61 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 27 Feb 2017 15:29:14 +0100 Subject: ppc/xics: introduce a XICSFabric QOM interface to handle ICSs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This interface provides two simple handlers. One is to get an ICS (Interrupt Source Controller) object from an irq number and a second to resend the irqs when needed.
