A more theoretical concern is that 32-bit pointers only allow you to address 4GB of memory. On Raspberry Pi 4, we use the ARM Large Physical Address Extension (LPAE) to access up to 8GB of memory, subject to the constraint that any process is limited to accessing 3GB (we reserve the top 1GB of the virtual address space for the kernel). Very few processes require more memory than this: happily Chromium, which is probably the most memory-intensive application in Raspberry Pi OS, spawns a process per tab. But some use cases will benefit from being able to allocate the entire memory of an 8GB Raspberry Pi 4 from a single process.<\/p>\n
