where can I find some examples to use linux srio in user space

user4544419

My evm is K2hk.

In MCSDK UG Chapter Developing Transports described that communication based on IPC transportsSRIO, but I don't want use that way, I wondering can I directly using Linux driver (such like open, write, ioclt a file）to visit /dev/srio_xx or using socket program like Ethernet.Is TI can provide examples like that? I can't find it from google.

I have install latest SDK program,it can support rapidio derive.But,It doesn't have some examples.I need some examples in user space to complete communication between device by srio derive.

Have you installed the Processor SDK LINUX in your Linux PC ?
Try to check the following path.
~/ti/ti-proceesor-sdk/board-support/

Yes. I had installed.but I can't find srio example in user space.It just support provide srio derive.But I don't know how to use this deriver.I need some examples to communicate with other device like FPGA by Linux srio)

Let me check with internal team on this.

There is an example in MCSDK HPC, Open MPI over SPI. However, TI has moved from MCSDK releases for Keystone-2 platforms to ProcSDK. Some features in HPC, such as OpenCL, OpenMP, are ported to ProdSDK, but OpenMPI hasn't. Nonetheless, the Open MPI over SRIO User Guide still holds a lot of useful information, .

Please be advised that the OpenMPI over SRIO has not been tested in Processor SDK, and this should be used as a reference.

OpenMPI is a high performance piont-to-point communication.But,I need lower performance to communicate with FPGA or other device without OpenMPI.It may be socket programing like Ethernet.So,How can I realize a communication between K2 device and FPGA over SRIO?
In addition,Is SRIO driver based on socket in Linux？
Thank you very much!

This forum is for TI products and their software components. For user space questions, this is not the right forum. Generic Linux questions should go to open source forum. TI's SRIO example shows how to use TI SRIO component, and targeted to show the initialization and functionality of the SRIO component. It will be users discretion on user space application.

For socket usage, please refer to Linux manual.

Hi,

I would like to know "will latest Processor SDK support rionet feature as in the old linux 3.8 version?"

Hi,
Addition to the above post, To be precise, as mention in the below link (srio rionet usage in linux)

Hi, Sivanantham,

The RapidIO User's Guide you mentioned is for Proc SDK Linux and the same features as in MCSDK.
