Update the LastBlockEntry return value when allocating a new page table block and the parent page table entry is not valid. Discovered when producing page table entries for a memory region that spans multiple page table entries of a parent page table block. Not very memory space efficient because the rest of the code could calculate a required page level that is deeper than some blocks of the memory region might require. Case that found the problem: MemoryRegion->VirtualBase = 0 MemoryRegion->Length = 0x7F000000 This fix will create an un-needed level of page table for address range 0 -> 0x40000000 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Garrett Kirkendall <garrett.kirkendall@amd.com> Reviewed-By: Olivier Martin <olivier.martin@arm.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15177 6f19259b-4bc3-4df7-8a09-765794883524 |
