Hi,

We are planning to write a PCIe EndPoint DMA driver with DMA Framework targeting x86 machine.  ( "https://www.kernel.org/doc/Documentation/dmaengine/provider.txt")
Our DMA controller is part of PCIe End Point.
We are targeting to measure PCIe performance with this Framework driver.

But when I see DMA Framework drivers is kernel source "drivers/dma" most of the drivers are platform drivers.

So DMA Framework is mainly targeted for platform drivers?

With current design model we need to have one DMA controller driver and PCIe EP client driver?

In which part of kernel source PCIe EP client driver will go?

Can we use DMA Framework on x86 ?

Thanks & Regards,
Bharat
