3b08b377 - dmaengine: ti: k3-udma: Add PSIL threads for AM62P and J722S

Wed, 13 Dec 2023 08:13:18 +0000

dmaengine: ti: k3-udma: Add PSIL threads for AM62P and J722SAdd PSIL thread information and enable UDMA support for AM62Pand J722S SoC. J722S SoC family is a superset of AM62P, thuscommon PSIL thread ID map is reused for both devices.For those interested, more details about the SoC can be foundin the Technical Reference Manual here: AM62P - https://www.ti.com/lit/pdf/spruj83 J722S - https://www.ti.com/lit/zip/sprujb3Signed-off-by: Vignesh Raghavendra Signed-off-by: Bryan Brattlof Signed-off-by: Vaishnav Achath Reviewed-by: Jai Luthra Link: https://lore.kernel.org/r/20231213081318.26203-1-vaishnav.a@ti.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/ti/Makefile

d7024191 - dmaengine: ti: k3-udma: Add glue layer for non DMAengine users

Mon, 23 Dec 2019 11:04:51 +0000

dmaengine: ti: k3-udma: Add glue layer for non DMAengine usersCertain users can not use right now the DMAengine API due to missingfeatures in the core. Prime example is Networking.These users can use the glue layer interface to avoid misuse of DMAengineAPI and when the core gains the needed features they can be converted touse generic API.The most prominent features the glue layer clients are depending on:- most PSI-L native peripheral use extra rflow ranges on a receive channel and depending on the peripheral's configuration packets from a single free descriptor ring is going to be received to different receive ring - it is also possible to have different free descriptor rings per rflow and an rflow can also support 4 additional free descriptor ring based on the size of the incoming packet- out of order completion of descriptors on a channel - when we have several queues to handle different priority packets the descriptors will be completed 'out-of-order'- the notion of prep_slave_sg is not matching with what the streaming type of operation is demanding for networking- Streaming type of operation - Ability to fill the free descriptor ring with descriptors in anticipation of incoming traffic and when a packet arrives UDMAP will form a packet and gives it to the client driver - the descriptors are not backed with exact size data buffers as we don't know the size of the packet we will receive, but as a generic pool of buffers to be used by the receive channel- NAPI type of operation (polling instead of interrupt driven transfer) - without this we can not sustain gigabit speeds and we need to support NAPI - not to limit this to networking, but other high performance operationsSigned-off-by: Grygorii Strashko Signed-off-by: Peter Ujfalusi Tested-by: Keerthy Link: https://lore.kernel.org/r/20191223110458.30766-12-peter.ujfalusi@ti.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/ti/Makefile

25dcb5dd - dmaengine: ti: New driver for K3 UDMA

Mon, 23 Dec 2019 11:04:50 +0000

dmaengine: ti: New driver for K3 UDMASplit patch for review containing: defines, structs, io and low levelfunctions and interrupt callbacks.DMA driver forTexas Instruments K3 NAVSS Unified DMA – Peripheral Root Complex (UDMA-P)The UDMA-P is intended to perform similar (but significantly upgraded) functionsas the packet-oriented DMA used on previous SoC devices. The UDMA-P modulesupports the transmission and reception of various packet types. The UDMA-P isarchitected to facilitate the segmentation and reassembly of SoC DMA datastructure compliant packets to/from smaller data blocks that are nativelycompatible with the specific requirements of each connected peripheral. MultipleTx and Rx channels are provided within the DMA which allow multiple segmentationor reassembly operations to be ongoing. The DMA controller maintains stateinformation for each of the channels which allows packet segmentation andreassembly operations to be time division multiplexed between channels in orderto share the underlying DMA hardware. An external DMA scheduler is used tocontrol the ordering and rate at which this multiplexing occurs for Transmitoperations. The ordering and rate of Receive operations is indirectly controlledby the order in which blocks are pushed into the DMA on the Rx PSI-L interface.The UDMA-P also supports acting as both a UTC and UDMA-C for its internalchannels. Channels in the UDMA-P can be configured to be either Packet-Based orThird-Party channels on a channel by channel basis.The initial driver supports:- MEM_TO_MEM (TR mode)- DEV_TO_MEM (Packet / TR mode)- MEM_TO_DEV (Packet / TR mode)- Cyclic (Packet / TR mode)- Metadata for descriptorsSigned-off-by: Peter Ujfalusi Tested-by: Keerthy Reviewed-by: Grygorii Strashko Link: https://lore.kernel.org/r/20191223110458.30766-11-peter.ujfalusi@ti.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/ti/Makefile

8c6bb62f - dmaengine: ti: k3 PSI-L remote endpoint configuration

Mon, 23 Dec 2019 11:04:48 +0000

dmaengine: ti: k3 PSI-L remote endpoint configurationIn K3 architecture the DMA operates within threads. One end of the threadis UDMAP, the other is on the peripheral side.The UDMAP channel configuration depends on the needs of the remoteendpoint and it can be differ from peripheral to peripheral.This patch adds database for am654 and j721e and small API to fetch thePSI-L endpoint configuration from the database which should only used bythe DMA driver(s).Another API is added for native peripherals to give possibility to pass newconfiguration for the threads they are using, which is needed to be able tohandle changes caused by different firmware loaded for the peripheral forexample.Signed-off-by: Peter Ujfalusi Tested-by: Keerthy Reviewed-by: Grygorii Strashko Link: https://lore.kernel.org/r/20191223110458.30766-9-peter.ujfalusi@ti.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/ti/Makefile
