RIFFA linux driver c coding question

[user123random]

Regarding https://github.com/KastnerRG/riffa/issues/30#issuecomment-373602633 , how do I rewrite this code segments https://github.com/KastnerRG/riffa/blob/master/c_c%2B%2B/linux/x64/test_apps/testutil.c#L150-L159 to two separate read and write threads ?

I am not sure how I should modify this function https://github.com/KastnerRG/riffa/blob/master/driver/linux/riffa_driver.c#L747

The developer documentation on RIFFA https://github.com/KastnerRG/riffa/blob/master/docs/riffa_documentation.pdf which is the last few pages of the PDF confuses me a lot.

Besides, if anyone have any idea about the c coding, do let me know.

For data loopback as in https://github.com/KastnerRG/riffa/blob/master/c_c%2B%2B/linux/x64/test_apps/testutil.c#L149-L159 , is there a way to synchronize the thread execution sequence if I am trying to make a single send() thread and another single recv() thread ?

// Send the data
sent = fpga_send(fpga, chnl, sendBuffer, numWords, 0, 1, 25000);
printf("Test %d: words sent: %d\n", j, sent);

GET_TIME_VAL(1);

if (sent != 0) {
// Recv the data
recvd = fpga_recv(fpga, chnl, recvBuffer, numWords, 25000);
printf("Test %d: words recv: %d\n", j, recvd);
}
