6.2.4. Data cache maintenance considerations

DCIMVAC operations in AArch32 and DC IVAC instructions in AArch64 perform an invalidate of the target address. If the data is dirty in the executing core then a clean is performed before the invalidate.

DCISW operations in AArch32 and DC ISW instructions in AArch64 perform both a clean and invalidate of the target set/way. The values of HCR.SWIO and HCR_EL2.SWIO have no effect.
