TLBIMVA, TLB Invalidate by VA

The TLBIMVA 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 only applies to the PE that executes this instruction.

Configuration

Attributes

TLBIMVA is a 32-bit System instruction.

Field descriptions

The TLBIMVA input value bit assignments are:

313029282726252423222120191817161514131211109876543210
VA0000ASID

VA, bits [31:12]

Virtual address to match. Any TLB entries that match the ASID value and VA value will be affected by this operation.

Bits [11:8]

Reserved, RES0.

ASID, bits [7:0]

ASID value to match. Any TLB entries that match the ASID value and VA value will be affected by this operation.

Global TLB entries that match the VA value will be affected by this operation, regardless of the value of the ASID field.

Executing the TLBIMVA instruction

Accesses to this instruction use the following encodings:

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