[edk2] [PATCH v2 0/2] Add Local APIC memory mapped space in GCD

Posted by Jeff Fan 7 years, 1 month ago

Local APIC memory mapped space should be added into GCD and be allocated.
Otherwise, UEFI firmware cannot get correct memory map for it. For example,
SMM profile feature needs to get the completed MMIO map to protect them.

v2:
  Consume AddMemoryMappedIoSpace() to handle the case that Local APIC
  memory space has already been added before per Laszlo's comments at:
  https://www.mail-archive.com/edk2-devel@lists.01.org/msg22561.html
  Tested on OvmfPkg.
