Re: Minimum tianocore payload

[Jorge Fernandez Monteagudo <jorgefm@cirsa.com>]

Hi all,


Thanks for your suggestions! I've been able to remove some unused modules comparing both Quartz dsc versions

and finally to avoid any info on screen I've added a very rude patch but it works:


--- a/IntelFrameworkModulePkg/Universal/BdsDxe/FrontPage.c
+++ b/IntelFrameworkModulePkg/Universal/BdsDxe/FrontPage.c
@@ -871,6 +871,8 @@ ShowProgress (
   EFI_GRAPHICS_OUTPUT_BLT_PIXEL Background;
   EFI_GRAPHICS_OUTPUT_BLT_PIXEL Color;

+  return EFI_TIMEOUT;
+
   if (TimeoutDefault != 0) {
     DEBUG ((EFI_D_INFO, "\n\nStart showing progress bar... Press any key to stop it! ...Zzz....\n"));

I don't need any info on screen and no keys entries, only go to the boot devices as fast as possible...

Regards

Jorge,

A couple of other examples can be found in the MinPlatform work.

https://github.com/tianocore/edk2-platforms/blob/devel-MinPlatform/Platform/Intel/KabylakeOpenBoardPkg/KabylakeRvp3/OpenBoardPkg.fdf
https://github.com/tianocore/edk2-platforms/blob/devel-MinPlatform/Platform/Intel/PurleyOpenBoardPkg/BoardMtOlympus/PlatformPkg.fdf
Both include https://github.com/tianocore/edk2-platforms/blob/devel-MinPlatform/Platform/Intel/MinPlatformPkg/Include/Fdf/CoreUefiBootInclude.fdf

FV.FvUefiBootUncompact has enough to boot to UEFI shell, with UART console.
We are looking to further reduce the contents, as the FvUefiBootUncompact contains SATA, USB, etc that aren't strictly necessary.

These three solutions are pretty similar, so cross referencing gets you a reasonable minimum list.  The main differences look to be around silicon policy configuration and boot media supported.

The other FV for OS boot and Security are not necessary initially, but should also be useful after you get minimum identified.  The OS boot FV adds minimal functionality for Linux/Windows style OS and the security FV adds secure boot functionality.

Regards,
Isaac

One example is Quark:

  https://github.com/tianocore/edk2/tree/master/QuarkPlatformPkg

It has both a minimum and a full example:

  https://github.com/tianocore/edk2/blob/master/QuarkPlatformPkg/QuarkMin.dsc
  https://github.com/tianocore/edk2/blob/master/QuarkPlatformPkg/QuarkMin.fdf

  https://github.com/tianocore/edk2/blob/master/QuarkPlatformPkg/Quark.dsc
  https://github.com/tianocore/edk2/blob/master/QuarkPlatformPkg/Quark.fdf

The min profiles uses a UART as a console and only supports booting from FLASH.  It does have a few additional features that could be removed related to menus and configuration, but at least a good example to study.

Mike
