mailbox: ti-msgmgr: Operate mailbox in polled mode during system suspend

2022-03-13T01:33:30+00:00

During the system suspend path we must set all queues to operate in polled mode as it is possible for any protocol built using this mailbox, such as TISCI, to require communication during the no irq phase of suspend, and we cannot rely on interrupts there. Polled mode is implemented by allowing the mailbox user to define an RX channel as part of the message that is sent which is what gets polled for a response. If polled mode is enabled, this will immediately be polled for a response at the end of the mailbox send_data op before returning success for the data send or timing out if no response is received. Finally, to ensure polled mode is always enabled during system suspend, iterate through all queues to set RX queues to polled mode during system suspend and disable polled mode for all in the resume handler.

soc: ti: k3-ringacc: add AM64 DMA rings support.

2020-12-11T15:50:09+00:00

The DMAs in AM64 have built in rings compared to AM654/J721e/J7200 where a separate and generic ringacc is used. The ring SW interface is similar to ringacc with some major architectural differences, like They are part of the DMA (BCDMA or PKTDMA). They are dual mode rings are modeled as pair of Rings objects which has common configuration and memory buffer, but separate real-time control register sets for each direction mem2dev (forward) and dev2mem (reverse). The ringacc driver must be initialized for DMA rings use with k3_ringacc_dmarings_init() as it is not an independent device as ringacc is. AM64 rings must be requested only using k3_ringacc_request_rings_pair(), and forward ring must always be initialized/configured. After this any other Ringacc APIs can be used without any callers changes.

soc: ti: k3-ringacc: Use correct device for allocation in RING mode

2020-11-02T03:38:05+00:00

In RING mode the ringacc does not access the ring memory. In this access mode the ringacc coherency does not have meaning. If the ring is configured in RING mode, then the ringacc itself will not access to the ring memory. Only the requester (user) of the ring is going to read/write to the memory. Extend the ring configuration parameters with a device pointer to be used for DMA API when the ring is configured in RING mode. Extending the ring configuration struct will allow per ring selection of device to be used for allocation, thus allowing per ring coherency. To avoid regression, fall back to use the ringacc dev in case the alloc_dev is not provided. Signed-off-by: Peter Ujfalusi Reviewed-by: Grygorii Strashko Signed-off-by: Santosh Shilimkar

The sysfw ring configuration message has been extended to include virtid and asel value for the ring. Add the ASEL_VALID to TI_SCI_MSG_VALUE_RM_ALL_NO_ORDER as it is required for DMA rings. Instead of extending the current .config() ops - which would need same patch change in the ringacc driver - add ti_sci_msg_rm_ring_cfg struct and a new ops using it to configure the ring. This will allow easy update path in case new members are added for the ring configuration. Signed-off-by: Peter Ujfalusi Reviewed-by: Grygorii Strashko Signed-off-by: Santosh Shilimkar
