You might want to check our advice on how to pick a machine type for Arm: https://wiki.qemu.org/Documentation/Platforms/ARM#Guidelines_for_choosing_a_QEMU_machine Basically we suggest 'virt' unless you have a strong reason for wanting to emulate something else.
NB that we don't support PCI in our vexpress model (this is one reason we don't recommend it, it makes it a bit inflexible). -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1833101 Title: vexpress-a9 (but not -a15) creates two pl111 LCDs due to duplicate sysbus_create_simple("pl111", ...) calls Status in QEMU: Invalid Bug description: Hi, Just a small report that (12ec8bd is current master) https://github.com/qemu/qemu/blob/12ec8bd/hw/arm/vexpress.c#L652: ... vexpress_common_init() { ... sysbus_create_simple("pl111", map[VE_CLCD], pic[14]); ... ... and https://github.com/qemu/qemu/blob/12ec8bd/hw/arm/vexpress.c#L304: ... a9_daughterboard_init() { ... sysbus_create_simple("pl111", 0x10020000, pic[44]); ... ... result in two LCD panels when using vexpress-a9. vexpress-a15 does not appear to be affected (my -a9 kernel does not work with it, but I see only one pl111 created). Understandably (but still annoyingly), -nodefaults has no effect. This bug is most evident when using SDL (so I can use ",frame=off"), which dumps two top-level windows onto the screen. GTK hides this because, coincidentally, the pl111 that ends up being used is the one that is selected (possibly the one created last?), relegating this to an obscure glitch only noticeable if you scrutinize the menu. This is a bugreport as opposed to a pull request as I have no idea which call to remove - and complete ignorance of the potential housekeeping and consideration that may be warranted first. FWIW, a simple testcase can be made with the vmlinuz from https://people.debian.org/~aurel32/qemu/armhf/ and qemu-system-arm -M vexpress-a9 -kernel vmlinuz-3.2.0-4-vexpress -nodefaults -sdl Thanks!
