Line 203:
ARM found it necessary to warn that: ''These operations are not required to invalidate non-MONC Secure TLB entries''.
==== E2HC contexts (Section 2.10) ====
E2HC context TLB entries are tagged by the TLB as E2H, but have no security state tagging. They are coupled with an ASID if they are non-global.
TLB entries for E2HC contexts matching combinations of (E2H identification) or (E2H identification+ASID tagging) are required to be invalidated by:
* SMMU_TLBIALLH
* SMMU_TLBIVAH
* SMMU_TLBIVAH64
* SMMU_TLBIVALH64
* SMMU_TLBIALLNSNH
E2H identified TLB entries are not required to be invalidated by:
* Secure TLBI operations.
* SMMU_TLBIVMID.
* SMMU_TLBIVMIDS1
