TMDS64EVM: PCI communication queries

Part Number: TMDS64EVM

Hi Liu,

as our team is working on other priority work so i couldn't able to send this request earlier.

in continue to our last meeting i am drafting this where ever we need your detailed answers.

1) the test function which we are using in the PCIe testing some data is generated by it and sending through ioctl() , we want to understand what kind of data it is sending and how its generating , if we want to send our data where we can modify?

2)as we discussed in the meeting we have seen  different data transfer speeds for read and write operation for same size of data , you said there was a known issue , can you explain how we can address this issue if we want max speed for data transfer in our real time application?

3) also with bigger size of data we have seen data transfer speed also increasing , we wan to understand why we are not achieving the same data transfer rate with small size data? 

  • Hi Mahesh,

    The last discussion was more than a month ago, I now lost the context especially for your question #2 and #3. Could you please create two new E2E threads separately for question #2 and #3 with detailed data explaining the problem?

    I will address your question #1 here.
