I discovered a huge problem in my hook function: missing a return at the end of
the hook function.
Without this return the hook function will execute only once.
And, regions with type GRUB_MEMORY_RESERVED should be skipped. So the hook
function body should look like this:
if (type != GRUB_MEMORY_RESERVED) {
total_mem_bytes += size;
}
return GRUB_ERR_NONE;
After this change the result looks fine.
Regards,
Cinhi
