[PATCH kvmtool v6 1/3] aarch64: Populate the vCPU struct before target->init()

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

 



Move the vCPU structure initialisation before the target->init() call to
 keep a reference to the kvm structure during init().
This is required by the pvtime peripheral to reserve a memory region
while the vCPU is beeing initialised.
