Headless devices - BDS to use?

Headless devices - BDS to use?

[Kurt Kennett]

What BDS are headless devices (no display, serial port only) supposed to use?

The MdeModulePkg one seems to require Hii resources in order to work at all.

The ArmPlatformPkg BDS (that supported headless devices just fine) seems to be gone now.

It may require HII resources, but it works fine with just a serial port.

Okay, but there is no reference or example for such, correct?

Right now people who don't have a display must fumble about trying to get Hii resources they don't need, understand, or use to get it to work?

And there is no boot manager menu that is not graphics based?

K2,

The QuarkPlatformPkg is an example of a serial only console platform
that uses MdeModulePkg BDS.

Re: Headless devices - BDS to use?

[Kurt Kennett]

But it is pulling in:

INF  MdeModulePkg/Universal/DisplayEngineDxe/DisplayEngineDxe.inf
INF  MdeModulePkg/Universal/SetupBrowserDxe/SetupBrowserDxe.inf

Which are display based components.  Are these required in the image even though they are not used?

A browser and display engine take up a lot of space on a constrained storage system.

Re: Headless devices - BDS to use?

[Kinney, Michael D]

K2,

Those are only required for platforms that support user configuration.

The QuarkPlatformPkg supports UEFI Secure Boot which requires a Setup Browser.

If a platform does not require any user configuration, then these can be
removed.

Best regards,

Mike

The display output is character console based. It can be multiplexed to
several separate outputs, such as graphical consoles and serial
terminals, by including GraphicsConsoleDxe, ConSplitterDxe, ConPlatformDxe.

If you have no GOP, and only one serial console, then TerminalDxe should
be all you need.

The driver / protocol stack is not simple to see through (I'm sure I've
made a few mistakes above), but it is very modular. (I occasionally
spend the time to understand it all, and then I forget the details
again.) It should be possible to build up what you need (and only what
you need) iteratively.

Sorry, I was too terse. Yes, there are at least two examples. Please see OvmfPkg/OvmfPkgX64.dsc or ArmVirtPkg/ArmVirtQemu.dsc.

It seems (from a build report) that BdsDxe inherits a depex of

  gEfiHiiStringProtocolGuid AND
  gEfiHiiDatabaseProtocolGuid AND
  gEfiHiiConfigRoutingProtocolGuid

from the "MdeModulePkg/Library/UefiHiiServicesLib/UefiHiiServicesLib.inf" library instance.

These protocols are provided if you include "MdeModulePkg/Universal/HiiDatabaseDxe/HiiDatabaseDxe.inf" in your platform DSC.

> Right now people who don't have a display must fumble about trying to get Hii resources they don't need, understand, or use to get it to work?

I think the following section from ArmVirtQemu.dsc can be used well enough as an example:

  #
  # Bds
  #
  [...]
  MdeModulePkg/Universal/DisplayEngineDxe/DisplayEngineDxe.inf
  MdeModulePkg/Universal/SetupBrowserDxe/SetupBrowserDxe.inf
  MdeModulePkg/Universal/DriverHealthManagerDxe/DriverHealthManagerDxe.inf
  MdeModulePkg/Universal/BdsDxe/BdsDxe.inf
  MdeModulePkg/Logo/LogoDxe.inf
  MdeModulePkg/Application/UiApp/UiApp.inf {
    <LibraryClasses>
      NULL|MdeModulePkg/Library/DeviceManagerUiLib/DeviceManagerUiLib.inf
      NULL|MdeModulePkg/Library/BootManagerUiLib/BootManagerUiLib.inf
      NULL|MdeModulePkg/Library/BootMaintenanceManagerUiLib/BootMaintenanceManagerUiLib.inf
  }

I'm sure Ray (CC'd) will be able to advise you better.

I assume Nt32Pkg and EmulatorPkg should be possible examples too.

> And there is no boot manager menu that is not graphics based?

The above set of drivers provides a dialog / form based setup utility (incl. boot manager) that works well on serial. Also, IIRC the BCFG command can be used from the UEFI shell.
