ARM Memory Tagging Extension

Aynı teknik/mekanizma: bkz. Memory Tagging Extension (MTE). Armv8.5 lock-and-key memory safety; her 16-byte granule 4-bit tag taşır, pointer tag'iyle mismatch fault verir.

Mechanism

Bu not, Memory Tagging Extension (MTE) ile aynı donanım mekanizmasını anlatır (allocation tag vs address tag, 16-byte granule, TBI, sync/async/asymmetric reporting). Detaylı açıklama canonical not'tadır.

Walkthrough

Tam walkthrough canonical not'ta: Memory Tagging Extension (MTE).
