31.7.1.6.1. Setting up Descriptor and mSGDMA Configuration Flow
The following is the recommended software flow to setup the descriptor and configuring the mSGDMA.
- Build the descriptor list and terminate the list with a non-hardware owned descriptor (Owned By Hardware = 0).
- Configure mSGDMA by accessing dispatcher core control register (for example: to configure Stop on Error, Stop on Early Termination, etc…)
- Configure mSGDMA by accessing the Prefetcher core configuration register (for example: to write the address of the first descriptor in the first list to the next descriptor pointer register and set the Run bit to 1 to initiate transfers).
- While the core is processing the first list, your software may build a second list of descriptors.
- An IRQ can be generated each time a descriptor transfer is completed (depends whether transfer complete IRQ mask is set for that particular descriptor). If you only need an IRQ to be generated when mSGDMA finishes processing the first list, you only need to set transfer complete IRQ mask for the last descriptor in the first list.
- When the last descriptor in the first linked list has been processed, an IRQ will be generated if the descriptor polling is disabled. Following this, your software needs to update the next descriptor pointer register with the address of the first descriptor in the second linked list before setting the run bit back to 1 to resume transfers. If descriptor polling is enabled, software does not need to update the next descriptor pointer register (for second descriptor linked list onwards) and set the run bit back to 1. These 2 steps are automatically done by hardware. The address of the new list is indicated by next descriptor pointer fields of the previous list. The Prefetcher core polls for the Owned by Hardware bit to be 1 in order to resume transfers. Software only needs to flip the Owned by Hardware bit of the first descriptor in second linked list to 1 to indicate to the Prefetcher core that the second linked list is ready.
- If there are new descriptors to add, always add them to the list which the core is not processing (indicated by Owned By Hardware = 0). For example, if the core is processing the first list, add new descriptors to the second list and so forth. This method ensures that the descriptors are not updated when the core is processing them. Your software can read the descriptor in the memory to know the status of the transfer (for example; to know the actual bytes being transferred, any error in the transfer).
