* efi_loader: ACPI device node to textHeinrich Schuchardt2019-05-121-3/+3
| | | | | | | | | | | The device path to text protocol renders ACPI device nodes incorrectly. Use capital hexadecimal numbers as shown in the UEFI spec examples. Always output the optional UID. This matches what UEFI SCT expects and saves us an `if`. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* efi_loader: remove redundant statementHeinrich Schuchardt2018-09-231-1/+9
| | | | | | | | | | ascii2unicode() always ends the u16 string with '\0'. Remove redundant assignment. Add description for efi_str_to_u16() and ascii2unicode(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
* SPDX: Convert a few files that were missed beforeTom Rini2018-05-101-2/+1
| | | | | | | | | | | As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles.

* efi_loader: text output for device path end nodeHeinrich Schuchardt2018-01-221-0/+2
| | | | | | | | Without the patch a device path consisting only of an end node is displayed as '/UNKNOWN(007f,00ff)'. It should be displayed as '/'. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: support device path for IDE and SCSI disksHeinrich Schuchardt2018-01-221-0/+14
| | | | | | | | | Correctly create the device path for IDE and SCSI disks. Support for SATA remains to be done in a future patch. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: correct DeviceNodeToText for media typesHeinrich Schuchardt2017-12-161-12/+31
| | | | | | | | When converting device nodes and paths to text we should stick to the UEFI spec. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

* efi_loader: fix efi_convert_device_node_to_textHeinrich Schuchardt2017-12-011-66/+88
| | | | | | | | | | | | | | | | | | | | | | | | | We need to implement to different functions for the EFI_DEVICE_PATH_TO_TEXT_PROTOCOL: ConvertDeviceNodeToText ConvertDevicePathToText A recent patch screwed up efi_convert_device_node_to_text to expect a device path and not a node. The patch makes both service functions work again. efi_convert_device_node_to_text is renamed to efi_convert_single_device_node_to_text and efi_convert_device_node_to_text_ext is renamed to efi_convert_device_node_to_text to avoid future confusion. A test of ConvertDeviceNodeToText will be provided in a follow-up patch.

* efi_loader: efi_dp_str should print path not nodeHeinrich Schuchardt2017-12-011-7/+6
| | | | | | | | | | | | efi_dp_str is meant to print a device path and not a device node. The old coding only worked because efi_convert_device_node_to_text was screwed up to expect paths instead of nodes.

* efi_loader: size of media device path node represenationHeinrich Schuchardt2017-12-011-1/+1
| | | | | | | | | | | In the format specifier we want to specify the maximum width in case an ending \0 is missing. So slen must be used as precision and not as field width.

* efi_loader: Add mem-mapped for fallbackRob Clark2017-10-121-0/+9
| | | | | | | | | | | | When we don't have a real device/image path, such as 'bootefi hello', construct a mem-mapped device-path. This fixes 'bootefi hello' after devicepath refactoring.

* efi_loader: flesh out device-path to textRob Clark2017-09-201-63/+178
| | | | | | | | | | | It needs to handle more device-path node types, and also multiple levels of path hierarchy. To simplify this, initially construct utf8 string to a temporary buffer, and then allocate the real utf16 buffer that is returned. This should be mostly for debugging or at least not critical- path so an extra copy won't hurt, and is saner than the alternative.

* efi_loader: implement ConvertDeviceNodeToTextxypron.glpk@gmx.de2017-07-241-30/+91
| | | | | | | | | | | | | | | | | Move the logic for converting a node to text from efi_convert_device_path_to_text to convert_device_node_to_text. Provide a wrapper function convert_device_node_to_text_ext. As we use only shallow device paths so we can call directly call efi_device_node_to_text from efi_device_path_to_text. Add output for MAC addresses. Add output for not yet supported types/subtypes. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

ConvertPathToText is implemented for * type 4 - media device path * subtype 4 - file path This is the kind of device path we hand out for block devices. All other cases may be implemented later.
