From 925ef576a5e74a895657d166efc4b6c4b5ba9036 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 8 Dec 2009 13:11:45 +0100 Subject: [PATCH] default devices: vga adapter. Qemu creates a vga display for you in case you didn't specify one on the command line. Right now this is tied to the '-vga ' command line switch, which in turn causes trouble if you are creating your gfx card using '-device VGA,'. This patch adds a variable default_vga which says whenever a default serial line should be added. It is enabled by default. It is cleared when qemu finds '-vga' or '-device {VGA,Cirrus VGA,QEMUware SVGA}' on the command line. '-device VGA' still doesn't work though due to a initialization order issue (vga must init before calling i440fx_init_memory_mappings).
