[PATCH v3 3/4] KVM: arm64: Change CONFIG_KVM to a menuconfig entry

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Will Deacon <will@xxxxxxxxxx>

Changing CONFIG_KVM to be a 'menuconfig' entry in Kconfig mean that we
can straightforwardly enumerate optional features, such as the virtual
PMU device as dependent options.
