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

Commit Message

Jean-Philippe Brucker Oct. 13, 2021, 4:06 p.m. UTC

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.

Fixes: 6d7a85483a06 ("hw/arm/virt: Add default_bus_bypass_iommu machine option")
