TLBIALLH, TLB Invalidate All, Hyp mode

Executing TLBIALLH

If this instruction is executed in a Secure privileged mode other than Monitor mode, then the behavior is CONSTRAINED UNPREDICTABLE, and one of the following behaviors must occur:

• The instruction is UNDEFINED.
• The instruction is treated as a NOP.
• The instruction executes as if it had been executed in Monitor mode.

Accesses to this instruction use the following encodings in the System instruction encoding space:

coproc	opc1	CRn	CRm	opc2
0b1111	0b100	0b1000	0b0111	0b000

if PSTATE.EL == EL0 then UNDEFINED; elsif PSTATE.EL == EL1 then if EL2Enabled() && !ELUsingAArch32(EL2) && HSTR_EL2.T8 == '1' then AArch64.AArch32SystemAccessTrap(EL2, 0x03); elsif EL2Enabled() && ELUsingAArch32(EL2) && HSTR.T8 == '1' then AArch32.TakeHypTrapException(0x03); else UNDEFINED; elsif PSTATE.EL == EL2 then AArch32.TLBI_ALL(SecurityStateAtEL(EL2), Regime_EL2, Shareability_NSH, TLBI_AllAttr); elsif PSTATE.EL == EL3 then if !HaveEL(EL2) then UNDEFINED; else AArch32.TLBI_ALL(SS_NonSecure, Regime_EL2, Shareability_NSH, TLBI_AllAttr);
