fbl::RefPtr<SmmuBti> Create (Smmu & smmu, ktl::unique_ptr<StreamMatchRegGroup> smrg, ktl::unique_ptr<ContextBank> context_bank, BtiMode initial_mode)

Create a new BtiContext and have it take control of the (mandatory) SMRG

and (optional) Context Bank. On success, any of the supplied resources

(SMRG and CB) will be marked as unavailable in the owning SMMU's

bookkeeping.

void Shutdown (Smmu & smmu)

bool SmrIntersects (SmrValue stream_ids)

Test to see if a stream match register's ID/MASK pair could potentially

match any of the SMR values for any of the SMRGs who are members of this

SmmuBti.

void AddSmrg (Smmu & smmu, ktl::unique_ptr<StreamMatchRegGroup> smrg)

Add a new SMRG to the existing set of SMRGs for this BTI. If SMRG being

added is in translate mode, then it must be using the same context bank as

any pre-existing SMRGs in this BTI.

void OnEndOfLife ()

This BTI has reached the end of its life and needs to conduct final

cleanup. There are two possible ways to get here:

1) The final user-mode handle to the BTI is closed, and the BTI does not

have any active or quarantined PMTs (OnDispatcherZeroHandles).

2) The BTI is orphaned (its final handle was closed while it still held

PMTs), however the final PMT has now been unpinned and its final handle

closed, and there are no quarantined PMTs (OnPmtZeroHandles)
