回复: [edk2-devel] [PATCH] MdeModulePkg: AllocatePages for TranslateBmpToGopBlt

["gaoliming via groups.io" <gaoliming=byosoft.com.cn@groups.io>]

Chitralekha:
  I understand this limitation is PEI version AllocatePool. Do you meet with
the usage that TranslateBmpToGopBlt is consumed in PEI phase?

Thanks
