VMO representing a physical range of memory

Public Methods

Lock<CriticalMutex> * lock ()

Define the lock retrieval functions differently depending on whether we should be returning a

local lock instance, or the common one in the hierarchy_state_ptr. Due to the TA_RET_CAP

statements we cannot perform |if constexpr| or equivalent indirection in the function body, and

must have two completely different function definitions.

In the absence of a local lock it is assumed, and enforced in vm_object_lock.h, that there is a

shared lock in the hierarchy state. If there is both a local and a shared lock then the local

lock is to be used for the improved lock tracking.
