 4.4.4.2. PSL Procedure for Time-Sliced Programming Models

  Operations Performed by the First PSL (PSL_ID[F] = '1')

When the remove_element MMIO command is received by the first PSL, the PSL sets the completion status in the software command/status word.

  1. The PSL sets the completion status in the software command/status field to indicate that it is now safe to remove the process element from the linked list.

    • The status field in sw_command_status is set to x'0002' using a caching-inhibited DMA or special memory-update operation that is guaranteed not to corrupt memory if the operation fails. The final value of sw_command_status should be (x'00020002' || first_psl_id || link_of_element_to_remove).
