Hi,
I’ve been testing NTB over Microsemi PCIe switch for a few weeks using NTB_PERF
and other tools from the kernel over ntb_hw_switchtec.c (from https://github.com/Microsemi/switchtec-kernel)
I’d like to move to user space now and for starters I would like to do a simple MEMCPY over NTB to the peer’s memory.
What the best approach for this? What kernel drivers I must use/modify?
Thanks,

Best regards, Boris
There are a lot of people that create VFIO user drivers in place
of the kernel driver. That's probably an approach. Also, VFIO
mediated device approach may also be a possibility. Have the
kernel driver configure and carve out a virtual device for your
app to consume.
Thanks,

Best regards, Boris
