Understanding 52-bit virtual address support in the Arm64 kernel
Understanding 52-bit virtual address support in the Arm64 kernel: After 64-bit hardware became available, the need to handle larger address spaces (greater than 232 bytes) became obvious. With some vendors now offering servers with 64TiB (or more) of memory, x86_64 and arm64 now allow addressing adress spaces greater than 248 bytes (available with the default 48-bit address support). …
