From 3495b6b6101e680b6a7b27674f5d3e446b1cf013 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Sat, 22 Oct 2016 11:46:43 +0200 Subject: ppc/pnv: add a ISA bus MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As Qemu only supports a single instance of the ISA bus, we use the LPC controller of chip 0 to create one and plug in a couple of useful devices, like an UART and RTC. An IPMI BT device, which is also an ISA device, can be defined on the command line to connect an external BMC. That is for later. The PowerNV machine now has a console. Skiboot should load a kernel and jump into it but execution will stop quite early because we lack a model for the native XICS controller for the moment : [ 0.000000] NR_IRQS:512 nr_irqs:512 16 [ 0.000000] XICS: Cannot find a Presentation Controller !
