I am playing around with EDK2 on QEMU with a UEFI shell application and in the app
I allocate some memory using gBS->AllocatePool(EfiBootServicesData, ...)
Programmatically accessing the pointer returned works fine, but when I print
it, it does not seem to be what I would expect is a valid address.
I've allocated 4GB to the QEMU machine, which I believe starts at 0x40000000.
You can run the `memmap` command at the EFI Shell to see the layout.
But, when I print the address returned by AllocatePool the value is
"0x39177018".
Print != printf on some of the format string so be careful about that….
I figured it out. It was a dumb Print() formatting error that resulted in
the address getting truncated to 8 bytes.
Thanks,
Stuart
