Hi, everyone
When ARM64 boots, it setup 2 page tables ("idmap_pg_dir" and
"swapper_pgdir").
On turning on MMU, which page table is applied?
I heard that "idmap_pg_dir" is applied as soon as MMU is turned on.
I cannot understand why "idmap_pg_dir" is applied, which is for "Lower"
address.
As I understand, the virtual address of kernel code is in "Higher" address.
Can you explain why "idmap_pg_dir" is applied on MMU turning on?
Thanks in advance
J.Hwan Kim
