X-BeenThere: edk2-devel@lists.01.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: EDK II Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 20 Feb 2019 08:16:52 -0000 Content-Transfer-Encoding: 8bit In the EFI_RETURN_STATUS_EXTENDED_DATA structure from PI-1.7, there may be padding between the DataHeader and ReturnStatus members. The REPORT_STATUS_CODE_EX() macro starts populating the structure immediately after DataHeader, therefore the source data must provide for the padding. Extract the BmReportImageFailure() function from EfiBootManagerBoot(), prepare a zero padding (if any) in a temporary EFI_RETURN_STATUS_EXTENDED_DATA object, and fix the REPORT_STATUS_CODE_EX() macro invocation.
