TLBIMVAAIS, TLB Invalidate by VA, All ASID, Inner Shareable

The TLBIMVAAIS characteristics are:

Purpose

Invalidate all cached copies of translation table entries from TLBs that meet the following requirements:

From the entries that match these requirement, the entries that are invalidated are required for the following translation regime:

The invalidation applies to all PEs in the same Inner Shareable shareability domain as the PE that executes this System instruction.instructions.

Configuration

Attributes

TLBIMVAAIS is a 32-bit System instruction.

VA, bits [31:12]

Virtual address to match. Any unlocked TLB entries that match the VA will be affected by this System instructionoperation, regardless of the ASID.

Bits [11:0]

Reserved, RES0.
