GraphicsConsoleDxe (a UEFI_DRIVER under MdeModulePkg/Universal/Console)
determines the preferred video resolution from the dynamic PCDs
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution
In one of the next patches, we'd like to change these PCDs. In order for
GraphicsConsoleDxe to retrieve the new values dynamically,
- it must be linked with the non-null instance of PcdLib,
- OvmfPkg must provide dynamic defaults.
We keep MdeModulePkg's 800x600 default resolution. (The UEFI specification
requires video drivers to support 800x600.)
