* [efi] Provide efi_tpl_name() for transcribing TPLs in debug messagesMichael Brown2025-07-141-0/+21

* [efi] Allow use of typed pointers for efi_open() et alMichael Brown2025-03-241-12/+6Star
| | | | | | | | | Provide wrapper macros to allow efi_open() and related functions to accept a pointer to any pointer type as the "interface" argument, in order to allow a substantial amount of type adjustment boilerplate to be removed. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Eliminate uses of HandleProtocol()Michael Brown2025-03-241-5/+1Star
| | | | | | | | It is now simpler to use efi_open() than to use HandleProtocol() to obtain an ephemeral protocol instance. Remove all remaining uses of HandleProtocol() to simplify the code. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Use driver name only from driver binding handles in debug messagesMichael Brown2025-03-211-6/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some non-driver handles may have an installed component name protocol. In particular, iPXE itself installs these protocols on its SNP device handles, to simplify the process of delegating GetControllerName() from our single-instance driver binding protocol to whatever child controllers the relevant EFI driver may have installed. For non-driver handles, the device path is more useful as debugging information than the driver name. Limit the use of the component name protocols to handles with a driver binding protocol installed, so that we will end up using the device path for non-driver handles such as the SNP device. Continue to prefer the driver name to the device path for handles with a driver binding protocol installed, since these will generally map to things we are likely to conceptualise as drivers rather than as devices. Note that we deliberately do not use GetControllerName() to attempt to get a human-readable name for a controller handle. In the normal course of events, iPXE is likely to disconnect at least some existing drivers from their controller handles. This would cause the name obtained via GetControllerName() to change. By using the device path instead, we ensure that the debug message name remains the same even when the driver controlling the handle is changed. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Prefer driver name to device path for debug messagesMichael Brown2025-03-201-3/+3
| | | | | | | | The driver name is usually more informative for debug messages than the device path from which a driver was loaded. Try using the various mechanisms for obtaining a driver name before trying the device path. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Attempt to retrieve driver name from image handle for debug messagesMichael Brown2025-03-201-0/+91
| | | | | | | | | Not all drivers will install the driver binding protocol on the image handle. Accommodate these drivers by attempting to retrieve the driver name via the component name protocol(s) located on the driver binding's ImageHandle, as well as on the driver handle itself.

* [efi] Allow efi_guid_ntoa() to be used in non-EFI buildsMichael Brown2025-03-111-236/+0Star
| | | | | | | | | | | The debug message transcription of well-known EFI GUIDs does not require any EFI boot services calls. Move this code from efi_debug.c to efi_guid.c, to allow it to be linked in to non-EFI builds. We continue to rely on linker garbage collection to ensure that the code is omitted completely from any non-debug builds. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Use long forms of device paths in debug messagesMichael Brown2024-03-041-1/+1
| | | | | | | | | | | | | | We currently call ConvertDevicePathToText() with DisplayOnly=TRUE when constructing a device path to appear within a debug message. For ATAPI device paths, this will unfortunately omit some key information: the textual representation will not indicate which ATA bus or drive is represented. This can lead to misleading debug messages that appear to refer to identical devices. Fix by setting DisplayOnly=FALSE to select the long form of device path textual representations.

* [efi] Avoid modifying PE/COFF debug filenameMichael Brown2023-11-291-2/+2
| | | | | | | | | | | | | The function efi_pecoff_debug_name() (called by efi_handle_name()) is used to extract a filename from the debug data directory entry located within a PE/COFF image. The name is copied into a temporary static buffer to allow for modifications, but the code currently erroneously modifies the original name within the loaded PE/COFF image. Fix by performing the modification on the copy in the temporary buffer, as originally intended. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [base16] Add buffer size parameter to base16_encode() and base16_decode()Michael Brown2015-04-241-1/+1
| | | | | | | | | | | | | | The current API for Base16 (and Base64) encoding requires the caller to always provide sufficient buffer space. This prevents the use of the generic encoding/decoding functionality in some situations, such as in formatting the hex setting types. Implement a generic hex_encode() (based on the existing format_hex_setting()), implement base16_encode() and base16_decode() in terms of the more generic hex_encode() and hex_decode(), and update all callers to provide the additional buffer length parameter.
