The ITLBIMVA characteristics are:
Invalidate all cached copies of translation table entries from instruction 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.
Arm deprecates the use of this instruction. It is only provided for backwards compatibility with earlier versions of the Arm architecture.
ITLBIMVA is a 32-bit System instruction.
The ITLBIMVA input value bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
VA | 0 | 0 | 0 | 0 | ASID |
Virtual address to match. Any TLB entries that match the ASID value and VA value will be affected by this operation.
Reserved, RES0.
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.
Accesses to this instruction use the following encodings:
opc1 | opc2 | CRn | coproc | CRm |
---|---|---|---|---|
0b000 | 0b001 | 0b1000 | 0b1111 | 0b0101 |
