* efi_loader: fix typosHeinrich Schuchardt2018-12-021-4/+4
| | | | | | | Fix typos in EFI subsystem comments. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.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: add missing breaksRob Clark2017-12-011-0/+2
| | | | | | | | | | Otherwise with GUID partition types you would end up with things like: .../HD(Part0,Sig6252c819-4624-4995-8d16-abc9cd5d4130)/HD(Part0,MBRType=02,SigType=02) Signed-off-by: Rob Clark <robdclark@gmail.com> [agraf: rebased] Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: comments for EFI_DEVICE_PATH_TO_TEXT_PROTOCOLHeinrich Schuchardt2017-12-011-0/+24

* 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>
* efi_loader: implement EFI_DEVICE_PATH_TO_TEXT_PROTOCOLxypron.glpk@gmx.de2017-07-191-0/+67
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.
