[RFC PATCH 3/3] KVM: selftests: Add vgic initialization for dirty log perf test for ARM

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

 



For ARM64, if no vgic is setup before the dirty log perf test, the
userspace irqchip would be used, which would affect the dirty log perf
test result.
