VPERMI2Q

Permutes two 512-bit vectors of quadwords. For each quadword in the destination vector, the instruction selects a quadword from either the first or second source vector based on the index provided in the immediate operand.

The table below specifies the supported source and destination operands.

DO NOT support LOCK

This instruction SHALL only be executed in 64-bit mode. It is NOT supported in compatibility mode.

The immediate operand MUST be a valid index; providing an immediate value that exceeds the range of available quadwords in the source vectors will result in undefined behavior or an illegal instruction exception depending on the specific processor implementation. This instruction requires the AVX-512DQ instruction set extension to be enabled in the CPU.
