As we discussed before, we need to have both options.
Thanks
Sean
Maybe I didn’t explain my idea clearly.
That is:
You can get the screen resolution in the code that produces Logo protocol.
You can return a carefully-calculated X/Y value to make the logo at MS preferred position.
Are you suggesting that the exiting logic be updated for this use case without adding a new enum?
Ray,
Are you suggesting that the exiting logic be updated for this use case without adding a new enum?
Sean, can you provide a revised patch that does this?
Thanks,
Mike
I need a reason of adding EdkiiPlatformLogoDisplayAttributeMicrosoftRecommended.
In my opinion, without adding this new enum value, it’s still possible to support MS recommendation.
Where would you suggest this code goes? edk2 should support both Microsoft recommended and "normal". The original patch handled this well.
The logic I shared below is from the LogoDxe driver which produces EDKII_PLATFORM_LOGO_PROTOCOL.
This driver should know the image size and it can account for the image size.
Thanks,
Ray
Thank you, it does, and I think it will work for most splash images. However, the way it's written in my patch accounts for the
Image size. This will handle splash images that are equal to, or larger than the resolution of the display.
Sean,
I remember that I evaluated the BGRT requirement when designing the PlatformLogo protocol.
So, I went back to got the code I wrote long time ago as below.
I didn't try to understand them now. Does it make sense to you?
Status = gBS->HandleProtocol (gST->ConsoleOutHandle, &gEfiGraphicsOutputProtocolGuid, (VOID **) &GraphicsOutput);
if (!EFI_ERROR (Status)) {
//
// Center of LOGO is in the vertical position 38.2% when PcdBootLogoOnlyEnable is TRUE
// Y = (VerticalResolution - LogoHeight) / 2
// Y' = VerticalResolution * 0.382 - LogoHeight * 0.5
// OffsetY + Y = Y'
// OffsetY = Y' - Y = -0.118 * VerticalResolution
//
*Attribute = EdkiiPlatformLogoDisplayAttributeCenter;
*OffsetX = 0;
*OffsetY = -118 * (INTN) GraphicsOutput->Mode->Info->VerticalResolution / 1000;
}
Thanks,
Ray
