Learning about TLP Responses

[MrCoInSanity]

Hello, I'm making this ticket about sending TLP responses via DMA, I just have some basic questions I hope you can answer...

1, Does the DMA send TLP responses and if so, how can I modify them? 2, How can I see TLP responses that are sent? 2, If it doesn't send TLP responses, do you have any idea how I can achieve this? Thanks in advance!

Finally I would like to apologise in advnace for my lack of knowledge and probably obvouse questions,

thanks in advance!

1. Yes, DMA works by sending and receiving PCIe TLPs.
2. In PCILeech/MemProcFS add options: -device fpga -vvv. (Do it in PCILeech for simple requests, the printout will be massive if doing it with MemProcFS.
3. PCILeech have a tlp command wich allows you to send hand-crafted TLPs. Or use the leechcorepyc Python API.
