The TLBIMVAA characteristics are:
Invalidate all cached copies of translation table entries from TLBs that meet the following requirements:
From the entries that match these requirements, the entries that are invalidated are required for the following translation regime:
The invalidation only applies to the PE that executes this System instruction.
This instruction is present only when AArch32 is supported at any Exception level. Otherwise, direct accesses to TLBIMVAA are UNKNOWN.
TLBIMVAA is a 32-bit System instruction.
The TLBIMVAA 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 | RES0 |
Virtual address to match. Any unlocked TLB entries that match the VA will be affected by this System instruction, regardless of the ASID.
Reserved, RES0.
Accesses to this instruction use the following encodings:
coproc | opc1 | CRn | CRm | opc2 |
---|---|---|---|---|
0b1111 | 0b000 | 0b1000 | 0b0111 | 0b011 |
