UEFI EDKII Shell command that prints all available protocols grouped by their registered handles

UEFI EDKII Dynamic Shell Extension List Protocols

UEFI EDKII Shell command that prints all available protocols grouped by their registered handles.

Features

This shell command (UEFI driver) can be loaded (e.g. by a shell startup script) directly into the shell with the load command:

load ShellDynListProtocols.efi

Once done, the command connects with the shell's internal help:

help lp

To actually run the shell command just execute it without command line options:

lp

Get the software

There are no special releases available yet. Just go ahead and get latest source.

Installation

The shell command must be compiled for the specific target system.

Systemrequirements

This source is based EDKII which is required to build this shell command.

How to integrate into EDKII

It is recommended to place the software at ShellPkg/DynamicCommand/ShellDynListProtocols/ within the EDKII source. Add this to your DSC file like ShellPkg.dsc , EmulatorPkg.dsc or Nt32.dsc under the [Components] section:

  ShellPkg/DynamicCommand/ShellDynListProtocols/ShellDynListProtocols.inf

Visual Studio debugging using NT32 Emulator (Nt32.dsc)

To debug drivers you have to make sure Visual Studio can detect the loaded driver and load the PDB file and addresses properly.
Add this to your DSC file under the [BuildOptions] section or create the section when it is not available:

  DEBUG_*_*_DLINK_FLAGS = /EXPORT:InitializeDriver=$(IMAGE_ENTRY_POINT) /BASE:0x10000 /ALIGN:4096 /FILEALIGN:4096 /SUBSYSTEM:CONSOLE

Further it is recommended to have easier access to the driver within the emulator by mounting the target directory.
This can be done by modifying the PCD that is responsible for the mapped drives in Nt32.dsc.
The path must be added, let's say as third mapping to be mapped to fs2, and the size of the string must be increased like that:

BEFORE
  gEfiNt32PkgTokenSpaceGuid.PcdWinNtFileSystem|L".!........\EdkShellBinPkg\Bin\Ia32\Apps"|VOID*|106
AFTER
  gEfiNt32PkgTokenSpaceGuid.PcdWinNtFileSystem|L".!........\EdkShellBinPkg\Bin\Ia32\Apps!......\Shell\DEBUG_VS2015x86\IA32"|VOID*|256

Moreover it is recommended to have a startup.nsh next to SecMain.exe to enter the build directoy immediately at start where the built EFI executable is located:

fs2:

One can also add a further line to directly start the command automatically by adding this next command:

load ShellDynListProtocols.efi
lp
