Does NVMe driver supports PCIe multiple physical function device?

Question

Hi Community,

Does NVMe driver supports PCIe multiple physical function device? I also don't know whether there is multiple physical function device on the market or not, but I'd like to know is driver supports it.

Thanks.

Answer 1

There's no reason why it shouldn't work.  The PCIe bus driver knows how to enumerate multi-function devices, and the NVMe driver just gets assigned the register spaces.  It doesn't care.
