Hi ,<br> Iam currently working on the GE make DSP230 board consisting of Quad PowerPC8640 nodes interconnected by SRIO with Linux 2.6.34 . However the only way to access the SRIO is through rionet facility . Our requirement is to use the SRIO interconnect without the Ethernet overheads. This would definitely enable higher speeds (though I cant find any throughput figures for SRIO in Linux on the net ??? ). My query is that whether any attempt has been made to develop a standalone driver and API to access the messaging and doorbell services of SRIO . If no then request you to please provide inputs on the same. From my study I have the following thoughts for the driver :<br>
<br>a) Have a character device interface for user .<br>b) Basically use the rio support functions provided in rio.c like rio_add_inb_buffer , rio_add_outb_message to transfer and receive messages and add buffers .<br>c) Maintain a dedicated ring of buffers in the driver and transfer data to and from the buffer to user space .<br>
<br><br>Is this the right direction . Would really appreciate any inputs . thanks in advance.<br><br>Regards,<br><br>S.Saravanan<br>
