Bonjour.

My company is creating PCIe signal acquisition cards, pushing GB/s of data to memory.

I've already implemented in the driver of our cards a direct transfer to GPU memory using nVidia RDMA technology.

I've seen that the AMD cards also provide similar technology, named DirectGMA. Is it real?

Searching the AMD developper community for DirectGMA leads me nowhere. I feel dumb not finding what I look for. Could someone point me to the reference documentation, or a typical usage code of the DirectGMA, showing the calls to the AMD kernel module functions I need.

Thanks for your help.

Thanks for posting it. I have whitelisted you for the AMD Developers community.

The DirectGMA SDK is available here: https://github.com/GPUOpen-LibrariesAndSDKs/DirectGMA_P2P

Below is a related discussion which provides some insights about the DirectGMA feature and it's usage.

Thanks.
