The Ring Accelerator (RINGACC or RA) provides hardware acceleration to enable straightforward passing of work between a producer and a consumer. There is one RINGACC module per NAVSS on TI AM65x SoCs. The RINGACC converts constant-address read and write accesses to equivalent read or write accesses to a circular data structure in memory. The RINGACC eliminates the need for each DMA controller which needs to access ring elements from having to know the current state of the ring (base address, current offset). The DMA controller performs a read or write access to a specific address range (which maps to the source interface on the RINGACC) and the RINGACC replaces the address for the transaction with a new address which corresponds to the head or tail element of the ring (head for reads, tail for writes). Since the RINGACC maintains the state, multiple DMA controllers or channels are allowed to coherently share the same rings as applicable. The RINGACC is able to place data which is destined towards software into cached memory directly. Supported ring modes: - Ring Mode - Messaging Mode - Credentials Mode - Queue Manager Mode TI-SCI integration: Texas Instrument's System Control Interface (TI-SCI) Message Protocol now has control over Ringacc module resources management (RM) and Rings configuration. The Ringacc driver manages Rings allocation by itself now and requests TI-SCI firmware to allocate and configure specific Rings only. It's done this way because, Linux driver implements two stage Rings allocation and configuration (allocate ring and configure ring) while TI-SCI Message Protocol supports only one combined operation (allocate+configure).

|
Some SoCs use a different address map for CPU physical addresses and
|
|
peripheral DMA master accesses. If yours does, select this option in
|
|
your platform's Kconfig, and implement the appropriate mapping
|
|
functions in your platform's support code.
