The CPSW3G instance of CPSW on AM62AX SoC provides Ethernet functionality.
Currently, Ethernet is supported on Linux which runs on the A53 core on the
SoC, by allocating all of the DMA resources associated with CPSW to A53_2.
In order to enable use-cases where the Ethernet traffic is sent from or
consumed by various CPU cores on the SoC simultaneously, while at the
same time, maintaining backward compatibility with the existing use-case
of A53 being the sole entity that exchanges traffic with CPSW via DMA,
update the DMA resource sharing scheme on AM62AX SoC to the following:
--------------- -------------- ------------- ----------------
Resource WKUP_R5 MCU_R5 A53_2
--------------- -------------- ------------- ----------------
TX Channels [8] => 4 (Primary) 4 (Primary) 8 (Secondary)
TX Rings [64] => 32 (Primary) 32 (Primary) 64 (Secondary)
RX Channels [1] => 1 (Primary) 0 1 (Secondary)
RX Flows [16] => 6 (Primary) 10 (Primary) 16 (Secondary)
In the absence of primary owners of resources (existing use-case
where A53 owns all of the CPSW DMA resources), the secondary owner
can claim all of the resources as its own. For shared use-cases,
the resources that are not claimed by the primary are communicated
to the secondary owner allowing it to claim them. This ensures that
Linux on A53_2 can continue claiming all DMA resources associated
with CPSW in the absence of primary owners, while at the same time
providing users the flexibility to share CPSW DMA resources across
various CPU cores listed above if needed.
While Linux has been mentioned as the Operating System running
on A53, there is no dependency between the Operating System
running on A53 and its ability to claim the CPSW DMA resources
listed above.
