(BaseBoard Management Controllers) and the BT interface can be used to

perform in-band IPMI communication with their host.

(to be written)
|

The acquisition orders for mutexes are as follows:
|

|

- kvm->lock is taken outside vcpu->mutex
|
||||
|
||||
- kvm->lock is taken outside kvm->slots_lock and kvm->irq_lock
|

- kvm->slots_lock is taken outside kvm->irq_lock, though acquiring

them together is quite rare.

For spinlocks, kvm_lock is taken outside kvm->mmu_lock. Everything

else is a leaf: no other lock is taken inside the critical sections.
