Re: [PATCH v3 09/20] nvme-pci: check DMA ops when indicating support for PCI P2PDMA

quoted

Is this new ops only needed for the PCIe transport ? or do you have
following patches to use this op for the other transports ?

No, I don't think this will make sense for transports that are not based
on PCI devices.

If it is only needed for the PCIe then we need to find a way to
not add this somehow...

I don't see how we can do that. The core code needs to know whether the
transport supports this and must have an operation to query it.

Okay.
