From 1f6a88fffc7533a9fd64c74c298d82590277cb3b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Wed, 12 Jan 2022 11:28:27 +0100 Subject: ppc/pnv: Introduce support for user created PHB3 devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PHB3 devices and PCI devices can now be added to the powernv8 machine using : -device pnv-phb3,chip-id=0,index=1 \ -device nec-usb-xhci,bus=pci.1,addr=0x0 The 'index' property identifies the PHB3 in the chip. In case of user created devices, a lookup on 'chip-id' is required to assign the owning chip.
