I’m fielding a series of questions coming out of our compatriot team that deals with virtual FW (for HyperV). They’re seeing ARM64 systems that have lots of RAM vastly exceeding the TempRam that’s passed into the system due to HOB allocations to create all the 4k entries for the early page tables.
Is this a known limitation or are we doing something dumb?
Is there a way to sparsely populate the page tables and fill them in more in DXE?
I’ve seen some questions about 64k pages on the list before. Is that an option?
Thanks in advance!
