ARM SMMU versions 1 and 2: Difference between revisions
→E2HC contexts (Section 2.10)
| [unchecked revision] | [unchecked revision] |
Line 219:
* SMMU_TLBIVMID.
* SMMU_TLBIVMIDS1
Additionally, the standard SMMU_CBn_TLBI* operations work on E2HC context TLB entries, except that instead of matching based on VMID, they match based on (E2H identification) or (E2H identification + ASID tagging).
In particular '''other than the specific TLB invalidate operations bulleted above, E2HC contexts are not considered to be hypervisor contexts by the SMMU'''.
Operation of the TLB is UNPREDICTABLE if there exist TLB entries allocated in the cache identified as HYPC and E2HC concurrently. Software must invalidate the HYPC/E2HC TLBs when switching between operating the SMMU with E2HC vs HYPC support enabled. Please see Section 2.10, example 2-1 for a full listing of the procedure for enabling E2HC operation.
