Feng Tian of Intel recently checked in changes to the EDK-II trunk for the EFI_NVME_PASS_THRU_PROTOCOL, as part of the UEFI 2.5 checkins. This UEFI NVM Express protocol provides services that allow NVM Express commands to be sent to an NVM Express controller or to a specific namespace in a NVM Express controller.
I’ve found the definitions in the code, but not an implementation, so either the checkin hasn’t happened yet, I’ve missed it, or it’s a non-open source implementation that won’t be in the TianoCore code, I’m unclear. If you know, please speak up!
