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:

  • The entry is a stage 1 translation table entry, from any level of the translation table walk.
  • The entry would be used to translate the specified address.
  • If EL2 is implemented and enabled in the current Security state, the entry would be used with the current VMID.

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

  • If executed at Secure EL1 when EL3 is using AArch64, the Secure EL1&0 translation regime.
  • If executed in Secure state when EL3 is using AArch32, the Secure PL1&0 translation regime.
  • If executed in Non-secure state, the Non-secure PL1&0 translation regime.

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

Configuration

Attributes

TLBIMVAAIS is a 32-bit System instruction.

Field descriptions

The TLBIMVAAIS input value bit assignments are:

VARES0

VA, bits [31:12]

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

Bits [11:0]

Reserved, RES0.

Executing the TLBIMVAAIS instruction

Accesses to this instruction use the following encodings:

MCR{<c>}{<q>} <coproc>, {#}<opc1>, <Rt>, <CRn>, <CRm>{, {#}<opc2>}
