[edk2-devel] [PATCH] MdeModulePkg: Retrive boot manager menu from any fv
Posted by Zhiguang Liu 2 years, 12 months ago 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3384

Currently, UefiBootManagerLib has the below assumption:
  Assume the BootManagerMenuFile is in the same FV as the module links to this library.
It has some limitation now, so remove the assumption.

Hello Zhiguang,

Sorry for a question. Do you know what is the boot performance impact if 'GetSectionFromAnyFv()' is being used?
Any data on the impact for originally working platforms?

Best Regards,
Hao Wu

Re: [edk2-devel] [PATCH] MdeModulePkg: Retrive boot manager menu from any fv
Posted by Zhiguang Liu 2 years, 12 months ago 
Hi Hao,

I don't have the data about the boot performance.
However, I think it has little impact for the originally working platforms.
In function GetSectionFromAnyFv, It will first search section in current FV. 
If it finds the section, it will return succuss. 
Only if it can't find the section, it will take extra time to search in other FV. This case won't happen in originally working platforms

Thanks
Zhiguang

Thanks Zhiguang.
The implementation of GetSectionFromAnyFv() will try searching the caller's FFS first, so there should be no impact to currently working platforms.

Could you help to update the function comments for BmRegisterBootManagerMenu() to reflect this change (first searching the same FV, if fails then all FVs).
With this handled:

Hello Zhichao and Ray, do you have comments for this patch? Thanks in advance.
