Systems & methods for multi pf emulation using vfs in ssd controller

A method, comprising:

• enumerating at least one Physical Function (PF) exposed by a device using a root port of a Lightweight Bridge (LWB);
• enumerating at least one Virtual Function (VF) exposed by the device using the root port of the LWB;
• generating a plurality of PFs at an endpoint of the LWB for exposure to a host;
• and
• mapping the plurality of PFs at the endpoint of the LWB to the at least one PF and the at least one VF exposed by the device using an Application Layer-Endpoint (APP-EP) and an Application Layer-Root Port (APP-RP) of the LWB.

An article, comprising a non-transitory storage medium, the non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:

• enumerating at least one Physical Function (PF) exposed by a device using a root port of a Lightweight Bridge (LWB);
• enumerating at least one Virtual Function (VF) exposed by the device using the root port of the LWB;
• generating a plurality of PFs at an endpoint of the LWB for exposure to a host;
• and
• mapping the plurality of PFs at the endpoint of the LWB to the at least one PF and the at least one VF exposed by the device using an Application Layer-Endpoint (APP-EP) and an Application Layer-Root Port (APP-RP) of the LWB.
