UEFI Firmware Management Protocol definition
|
|
Firmware Management Protocol provides an abstraction for device to provide firmware
|
|
management support. The base requirements for managing device firmware images include
|
|
identifying firmware image revision level and programming the image into the device.
|
|
|
|
GetImageInfo() is the only required function. GetImage(), SetImage(),
|
|
CheckImage(), GetPackageInfo(), and SetPackageInfo() shall return
|
|
EFI_UNSUPPORTED if not supported by the driver.

|

Updates the firmware image of the device.

|
|
|
This function updates the hardware with the new firmware image.
|
|
This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
|
|
If the firmware image is updatable, the function should perform the following minimal validations
|
|
before proceeding to do the firmware image update.
|
|
- Validate the image authentication if image has attribute
|
|
IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
|
|
EFI_SECURITY_VIOLATION if the validation fails.
|
|
- Validate the image is a supported image for this device. The function returns EFI_ABORTED if
|
|
the image is unsupported. The function can optionally provide more detailed information on
|
|
why the image is not a supported image.
|
|
- Validate the data from VendorCode if not null. Image validation must be performed before
|
|
VendorCode data validation. VendorCode data is ignored or considered invalid if image
|
|
validation failed. The function returns EFI_ABORTED if the data is invalid.
|
|
|
|
VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
|
|
the caller did not specify the policy or use the default policy. As an example, vendor can implement
|
|
a policy to allow an option to force a firmware image update when the abort reason is due to the new
|
|
firmware image version is older than the current firmware image version or bad image checksum.
|
|
Sensitive operations such as those wiping the entire firmware image and render the device to be
|
|
non-functional should be encoded in the image itself rather than passed with the VendorCode.
|
|
AbortReason enables vendor to have the option to provide a more detailed description of the abort
|
|
reason to the caller.

|
|
|
@param[in] This A pointer to the EFI_FIRMWARE_MANAGEMENT_PROTOCOL instance.
