These series of lessons are intendend to get you started with UEFI programming in Linux with the help of TianoCore. Lessons description: - Lesson 00: Getting started guide for TianoCore. Compile OVMF and run it in QEMU - Lesson 01: Create a simplest app and run it in OVMF - Lesson 02: Create a simplest package - Lesson 03: Create `HelloWorld` app with the help of SystemTable services - Lesson 04: Use edk2 libraries to simplify our `HelloWorld` app - Lesson 05: Simplify build command with the help of files in the `Conf` folder - Lesson 06: Handle/Protocol databases internals - Part 1: Theory and raw access to an app ImageHandle - Lesson 07: Handle/Protocol databases internals - Part 2: Raw access to app protocols - Lesson 08: `HandleProtocol` API function. Information from the `ImageHandle` protocols - Lesson 09: Get ImageHandle protocols with the `ProtocolsPerHandle` API function - Lesson 10: `EFI_STATUS` type and `EFI_ERROR` macros - Lesson 11: Get EFI memory map information - Lesson 12: `EFI_SHELL_PARAMETERS_PROTOCOL`. Transform our EFI memory map to the Linux kernel style - Lesson 13: `ShellAppMain` entry point - Lesson 14: Get all variable names and GUIDs with the `gRT->GetNextVariableName` API - Lesson 15: Get and parse boot variables (BootOrder/BootCurrent/BootXXXX) with the `gRT->GetVariable` API - Lesson 16: Build our own boot option inside OVMF image similar to the UEFI shell app - Lesson 17: Add `WaitForEvent` function to our boot option app to see its output on booting - Lesson 18: Handle input from user with the `ReadKeyStroke` function - Lesson 19: Boot option modification with the help of `bcfg` command - Lesson 20: Intro to Platfrom Configuration Database (PCD). Declare and get simple fixed PCD - Lesson 21: Override order for PCD variables - Lesson 22: Feature flag PCD and its comparision to BOOLEAN fixed at build PCD - Lesson 23: PatchableInModule PCDs and how they can be changed via `GenPatchPcdTable`/`PatchPcdValue` utilities - Lesson 24: Dynamic/DynamicEx PCDs - Lesson 25: More on PCDs - Lesson 26: Tables referenced in `EFI_CONFIGURATION_TABLE` - Lesson 27: Get SMBIOS information with `dmem`/`EFI_SMBIOS_PROTOCOL`/`smbiosview` - Lesson 28: Get ACPI tables and save them to files with a help of `EFI_SHELL_PROTOCOL` - Lesson 29: Use `EFI_ACPI_SDT_PROTOCOL` and `ShellLib` to save a BMP image from the ACPI BGRT table - Lesson 30: Find all PCI root bridges in the system with a help of `LocateHandleBuffer`/`OpenProtocol` functions and use `EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL` to get all PCI functions in the system. - Lesson 31: Search `pci.ids` database to get PCI Vendor/Device information with a help of `ShellLib`/`PrintLib` functions ______ Usefull links: 1) Beyond BIOS: Developing with the Unified Extensible Firmware Interface, Third Edition by Vincent Zimmer and Michael Rothman (https://www.amazon.com/Beyond-BIOS-Developing-Extensible-Interface/dp/1501514784) 2) Harnessing the Uefi Shell: Moving The Platform Beyond Dos, Second Edition by Michael Rothman and Vincent Zimmer (https://www.amazon.com/Harnessing-UEFI-Shell-Moving-Platform/dp/1501514806) 3) https://github.com/tianocore-training https://github.com/Laurie0131 4) https://blog.fpmurphy.com/ https://github.com/fpmurphy/UEFI-Utilities-2019 5) https://github.com/andreiw/UefiToolsPkg _______ Check these if you don't afraid of the Chinese language: 6) Principles and Programming of UEFI, Dai Zhenghua (https://www.amazon.com/Combat-UEFI-Principles-Programming-Chinese/dp/B07W3GFLRM) https://github.com/zhenghuadai/uefi-programming 7) http://www.lab-z.com/iof/ 8) https://blog.csdn.net/luobing4365 https://gitee.com/luobing4365/uefi-exolorer _______ And for the Russian speakers: 9) https://habr.com/ru/users/CodeRush/posts/ # Specifications UEFI specifications (https://uefi.org/specifications): - [UEFI Specification](https://uefi.org/sites/default/files/resources/UEFI_Spec_2_9_2021_03_18.pdf) - [UEFI Platform Initialization Specification](https://uefi.org/sites/default/files/resources/PI_Spec_1_7_A_final_May1.pdf) - [UEFI Shell Specification](http://www.uefi.org/sites/default/files/resources/UEFI_Shell_2_2.pdf) EDK2 specifications (https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Documentation#specifications): - [Build Specification](https://edk2-docs.gitbook.io/edk-ii-build-specification/) - [Platform Description (DSC) File Specification](https://edk2-docs.gitbook.io/edk-ii-dsc-specification/) - [Package Declaration (DEC) File Format Specification](https://edk2-docs.gitbook.io/edk-ii-dec-specification/) - [Module Information (INF) File Specification](https://edk2-docs.gitbook.io/edk-ii-inf-specification/) - [Flash Description (FDF) File Specification](https://edk2-docs.gitbook.io/edk-ii-fdf-specification/) - [Platform Configuration Database Infrastructure Description](https://edk2-docs.gitbook.io/edk-ii-pcd-specification/) - [Multi-String .UNI File Format Specification](https://edk2-docs.gitbook.io/edk-ii-uni-specification/) - [VFR Programming Language Specification](https://edk2-docs.gitbook.io/edk-ii-vfr-specification/) - [Driver Writer's Guide](https://edk2-docs.gitbook.io/edk-ii-uefi-driver-writer-s-guide/) - [Module Writer's Guide](https://edk2-docs.gitbook.io/edk-ii-module-writer-s-guide/) - [EDKII User Manual](https://github.com/tianocore-docs/Docs/raw/master/User_Docs/EDK_II_UserManual_0_7.pdf)
