Going for the workaround I see! :-) INLINE COMMENTS > copy.c:56 > + int i, ndesc; > + unsigned long aviable_pages; > + It's spelled "available" instead of "aviable" :-) > copy.c:79-84 > + if (KERNEL_PHYSICAL_BASE < start || > + KERNEL_PHYSICAL_BASE >= end) > + continue; > + > + if (p->Type != EfiConventionalMemory) > + continue; Please also handle existing allocations. If those allocations represent free/usable memory after boot services has exited, then they are for all practical purposes "conventional memory". Also: please make sure that KERNEL_PHYSICAL_BASE is covered by usable memory to begin with. As such, we may have multiple memory descriptors that overlap with [2MB..2MB+nr_pages*PAGE_SIZE]. As long as they are free to use after boot services has exited, we're ok. We can only reduce the staging size if [2MB..2MB+delta] is usable when [2MB+delta..2MB+nr_pages*PAGE_SIZE] isn't. We can reduce the staging area to delta/PAGE_SIZE. But if 2MB isn't usable, we cannot reduce (or put differently we have to reduce to 0).
