Re: [edk2-devel] [PATCH 1/3] MdeModulePkg/BootLogoLib: Add option to follow BGRT specification

[Pedro Falcato]

[-- Attachment #1: Type: text/plain, Size: 4538 bytes --]

Hi Sean,

I think it's clear from the wording that the 38.2% thing is a
recommendation and not mandatory. I was curious and checked out the ACPI
spec and they appear to not mention that at all. Maybe reword things to
"Microsoft recommendation"?

Thanks,
Pedro

Sean:

 According to the description, I agree with Pedro that this is a recommendation and not mandatory. Do you think so?

[Liming] Please use PcdGetBool (PcdFollowMicrosoftRecommended), 
PcdGetBool is more flexible for PCD usage.
