Thanks for following up, and helping me figure some things out. I coincidentally stumbled on https://translatedcode.wordpress.com/2016/11/03/installing-debian-on- qemus-32-bit-arm-virt-board/ a few days ago, landed on the page you linked, and immediately wanted to try it.
Thanks very much for prompting me to properly think^Wmuddle through and properly model the fussy details of my situation so I could finally see a solution :) I happen to be fiddling with an ARMv8 binary built with a Squeeze-era /usr/lib, so I was using vexpress-a9 primarily because a prebuilt Squeeze environment was available from https://people.debian.org/~aurel32/qemu/armel/, and I was able to copy over the /lib/modules/ and kernel image from https://people.debian.org/~aurel32/qemu/armhf/ and have a working system. ...And so obviously I can get more or less the same result by putting a chroot of my current setup on top of a newer kernel and userspace. Duh/facepalm. That looks to be my next step. Perhaps I'll use Alpine so the environment boots quickly :D (I find Jessie takes 3min, while Wheezy takes 60sec... that was one of my hesitations to fiddle too much actually) But first stop, a (prebuilt, most definitely definitely prebuilt) cross compiler. I don't NEED to make my laptop get to 72°C :) -- 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!
