From d1214b819f26dcf95329af624e74bf42eeeb1a9a Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Mon, 6 Jan 2020 15:56:37 +0100 Subject: [PATCH] spapr, pnv, xive: Add a "xive-fabric" link to the XIVE router MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In order to get rid of qdev_get_machine(), first add a pointer to the XIVE fabric under the XIVE router and make it configurable through a QOM link property. Configure it in the spapr and pnv machine. In the case of pnv, the XIVE routers are under the chip, so this is done with a QOM alias property of the POWER9 pnv chip.
