[edk2-devel] [Patch edk2-platforms V2] Intel/BoardModulePkg: sort load option in the first boot
Posted by Zhiguang Liu 3 years, 1 month ago
Currently, load option is only sorted when setup is the first priority in boot
option. However, Below change in UefiBootManagerLib puts setup in the end, which
causes the sort function won't be called.
  MdeModulePkg/UefiBootManagerLib: Put BootMenu at the end of BootOrder
  SHA-1: 7f34681c488aee2563eaa2afcc6a2c8aa7c5b912

This patch will set a NV variable in the first boot, and sort the boot option
in first boot.

[edk2-devel] 回复: [Patch edk2-platforms V2] Intel/BoardModulePkg: sort load option in the first boot
Posted by gaoliming 3 years, 1 month ago
Zhiguang:
  I see QuarkPlatformPkg uses PCD gQuarkPlatformTokenSpaceGuid.PcdBootState
to decide whether current boot is the first boot or not. 
  This PCD is configured as DynamicHiiPcd, and be set in
Platform\Intel\QuarkPlatformPkg\Library\PlatformBootManagerLib\PlatformBootM
anager.c

  Can you use the same solution in Intel BoardModulePkg?

Thanks

Re: [edk2-devel] 回复: [Patch edk2-platforms V2] Intel/BoardModulePkg: sort load option in the first boot
Posted by Zhiguang Liu 3 years, 1 month ago
Hi Liming,

Thanks for the comments. This patch is merged before this comment, but I can still send another patch to modify if needed.

However, I think the implement in this patch is more simple.
The implement in QuarkPlatformPkg need changes in inf, dec and dsc files, and is not as intuitive as just getting and setting a variable.
It may be simpler if the implements can reuse a same DynamicHiiPcd, do you think it is possible?
If I misunderstand anything, please correct me.

Thanks
Zhiguang

Posted by gaoliming 3 years, 1 month ago
Zhiguang:
  This is the common platform usage. I suggest to apply the same solution. My solution is to define this PCD PcdBootState in MdeModulePkg.dec, and add MdeModule.dsc.inc file that defines this PCD as DynamicHii PCD, platform DSC includes MdeModule.dsc.inc file, platform modules consume this PCD (set/get).

Re: [edk2-devel] 回复: [Patch edk2-platforms V2] Intel/BoardModulePkg: sort load option in the first boot
Posted by Ni, Ray 3 years, 1 month ago
Liming,
Using HII PCDs introduces too many software layers that may cause potential bugs if any layer is not proper implemented (Imaging a case when a platform forgets to include the mdeModule.dsc.inc).

Variable used here is very straightforward.

That was also the reason when I redesigned the BDS 10 years ago, I chose not to include the PcdBootState into the MdeModulePkg but left that in platform.

I agree with you that consistency is better. And I suggest we submit a Bugzilla to change all open platforms to use variable directly for first boot detection.

Thanks,
Ray
