[edk2-devel] reg: Load File 2 Protocol

[Sivaraman Nainar via groups.io]

Hello Maciej:

This is regarding an inquiry about usage of Load File 2 Protocol in HTTP Boot. From the  UEFI Specification refence below the driver supposed to install Load File 2 Protocol to get the HTTP boot file loaded. The HTTPBootDxe driver installs the Load File protocol only.

2.6.3 Driver-Specific Elements There are a number of UEFI elements that can be added or removed depending on the features that a specific driver requires. Drivers can be implemented by platform firmware developers to support buses and devices in a specific platform. Drivers can also be implemented by add-in card vendors for devices that might be integrated into the platform hardware or added to a platform through an expansion slot. The following list includes possible driver features, and the UEFI elements that are required for each feature type:

  1.  If a driver is written for a boot device that is not a block-oriented device, a file system-based device, or a console device, then the EFI_LOAD_FILE2_PROTOCOL must be implemented.
Do you think the driver should install Load File 2 Protocol also? May you please comment on the above recommendation from UEFI Spec to install Load File2 protocol.

Thanks
Siva
