data for S3 FullResume in FPDT.
|
|
|
|
@param[in] PeiServices An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
|
|
@param[in] CodeType Indicates the type of status code being reported.
|
|
@param[in] Value Describes the current status of a hardware or software entity.
|
|
This included information about the class and subclass that is used to
|
|
classify the entity as well as an operation.
|
|
@param[in] Instance The enumeration of a hardware or software entity within
|
|
the system. Valid instance numbers start with 1.
|
|
@param[in] CallerId This optional parameter may be used to identify the caller.
|
|
This parameter allows the status code driver to apply different rules to
|
|
different callers.
|
|
@param[in] Data This optional parameter may be used to pass additional data.
|
|
|
|
@retval EFI_SUCCESS Status code is what we expected.
|
|
@retval EFI_UNSUPPORTED Status code not supported.
