[RESEND PATCH 0/2] Fix machine parameter default_bus_bypass_iommu

[Jean-Philippe Brucker]

The machine option "default_bus_bypass_iommu" is broken since commit
d8fb7d0969d5 ("vl: switch -M parsing to keyval"). Fix both machines that
implement it.

[RESEND PATCH 1/2] hw/arm/virt: Rename default_bus_bypass_iommu

[Jean-Philippe Brucker]

Since commit d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.

This affects option default_bus_bypass_iommu which was introduced in the
same release:

$ qemu-system-aarch64 -M virt,default_bus_bypass_iommu=on
qemu-system-aarch64: Property 'virt-6.1-machine.default-bus-bypass-iommu' not found

Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.

Hi Paolo,

Please could you take a look at these fixes?  Another patch adds a test
that uses default_bus_bypass_iommu [1], and is blocked by this.

Thanks,
Jean

I can merge this one but I think it's independent of the
ARM patch, right? So just two independent patches.

Yes they are independent
