Hello developer community,
I want to allow a *sysbus *type device to boot with kernel image(arm
architecture) via Qemu command line .
When I run qemu arm system executable with *-device *option via qemu
command line,I get following error message
> qemu-system-arm: -device pl061: Parameter 'driver' expects pluggable
device type
So, how to allow a sysbus device via command line?
Is there any working patch?

Hi, it looks like the pl061 device is not declared "user creatable" so it is unavailable from the CLI. As a sysbus device, QEMU is not aware, in the abstract, of how to "connect" the device to other devices. See the sysbus class initialization code for more detail: https://github.com/qemu/qemu/blob/master/hw/core/sysbus.c#L301 However, It looks like these boards/devices create such a device: hw/arm/highbank hw/arm/realview hw/arm/sbsa-ref hw/arm/stellaris hw/arm/versatilepb hw/arm/virt If you want one on some other kind of machine, you'll need to write it up yourself in the machine board code, but you didn't tell us what version of QEMU you're using, what machine type you are trying to use, etc. --js ^ permalink raw reply [flat|nested] 5+ messages in thread
