From: Mark Cave-Ayland Date: Thu, 7 Oct 2021 22:12:53 +0000 (+0100) Subject: q800: wire macfb IRQ to separate video interrupt on VIA2 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=efd0c37edc8efe7dccc2356f4a07f33581bc9e67;p=qemu.git q800: wire macfb IRQ to separate video interrupt on VIA2 Whilst the in-built Quadra 800 framebuffer exists within the Nubus address space for slot 9, it has its own dedicated interrupt on VIA2. Force the macfb device to occupy slot 9 in the q800 machine and wire its IRQ to the separate video interrupt since this is what is expected by the MacOS interrupt handler.
