Freescale Semiconductor be divided into two sets: portals for use by the Linux kernel and portals for use by USDPAA threads. 2 Production Release Features P4080 PCIE Adapter SDK has two software components – a BSP component that runs on the P4080 adapter and x86 host software. 2.1 P4080 PCIE Adapter BSP • RCW with Root Complex (to support stand-alone host mode) and End Point mode. • U-boot with dual bank boot support. • Support for standard u-boot commands. • Linux USDPAA SDK 2.3 and DTS. • 1G management port support. • Linux SD card support. • Linux USB support. • Software Framework on P4080 to support exposure of multiple Hardware functions to Host. • USDPAA Linux P4080 PCIE driver that enables control and data path between P4080 cores and x86 host with multi-ring support. The control path includes the initialization handshake between Host PCIe driver and P4080 PCIe driver, command requests and responses. The data path includes the exchange of data packets between the Hardware Function Drivers on Host to P4080 Hardware Functions and vice versa. • USDPAA Linux P4080 PCIE driver also supports a command request/response mechanism for receiving host commands for multiple hardware functions and providing response to host. • USDPAA Linux P4080 Ethernet driver that sends/receives network packets from/to two 10G ports on multi-core host. The Ethernet driver has support for multiple host descriptor Tx/Rx rings and PCD Frame Queues. © Freescale Semiconductor, Inc., 2011. All rights reserved. Freescale Confidential Proprietary Page 6
Freescale Semiconductor • USDPAA PCIE Packet Application that links in the PCIE Packet driver and Ethernet driver libraries and showcases the bi-directional control and data path between P4080 cores and multi-core host. • Support of 8 Tx Frame Queues and 8 Tx confirmation Frame Queues for each 10G port on P4080. • Support of 8 PCD Frame Queues for each 10G port on P4080. • USDPAA APIs for support of Basic Direct and Basic Chaining DMA. • Support for statistics of two 10G ports. 2.2 x86 Host software • Software Framework on x86 Host to support exposure of multiple Hardware functions to x86 Host. • PCIE Packet driver ▪ Dynamically loaded and unloaded as a module. Also supports automatic load of modules on host boot-up. ▪ Executes PCIE initialization. ▪ Initialization handshake with P4080 driver. ▪ Supports MSI for the device. ▪ Command Request/Response mechanism to P4080. ▪ API to upper-level (Ethernet) drivers – enqueue to Tx descriptor ring. ▪ Callback for Rx ring of upper-level (Ethernet) drivers. ▪ API to enqueue commands to the Command Ring. ▪ Callback for handling command ring responses. © Freescale Semiconductor, Inc., 2011.
