4.3.7.11. Enabling the SMMU

Software enables the SMMU by writing to SMMU_CR0 after Stream Table is populated.

  • Ensure that all the Stream Table entries are populated in memory.
  • Set the SMMU_CR0.SMMUEN bit to 1.
  • Check that the enable operation is complete by polling SMMU_CR0ACK until SMMUEN reads as 1.
