This seems odd to me:
(1) the error message you quote is for a15mpcore.c, not virt.c
This is the first device the virt board selects:
config ARM_VIRT
bool
imply PCI_DEVICES
imply TEST_DEVICES
imply VFIO_AMD_XGBE
imply VFIO_PLATFORM
imply VFIO_XGMAC
imply TPM_TIS_SYSBUS
select A15MPCORE
...
(2) shouldn't this be prevented by something saying "don't build
guest architecture X boards into Y-softmmu", rather than a specific
flag for a specific arm board ?
Yes, agreed. This surgical change was quicker for my testing, but we
don't need this patch right now, so let's drop it.
thanks
