From 834fc12721b90c8542304a8be6463974562f8916 Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Sat, 4 Mar 2023 12:40:41 +0100 Subject: [PATCH] hw/ppc/prep: Fix wiring of PIC -> CPU interrupt Commit cef2e7148e32 ("hw/isa/i82378: Remove intermediate IRQ forwarder") passes s->cpu_intr to i8259_init() in i82378_realize() directly. However, s- >cpu_intr isn't initialized yet since that happens after the south bridge's pci_realize_and_unref() in board code. Fix this by initializing s->cpu_intr before realizing the south bridge.
