Problem Description A program implements a circular buffer using a 256-element array with byte-type data as an index, leveraging the overflow behavior where values wrap around to zero: #include "stdint.h" int main() { uint8_t index = 0; uint16_t array[256] = { 0 }; while(1) { array[index++...
Kernel virtual address map on 32‑bit ARM PAGE_OFFSET: base of kernel virtual space at 0xC000_0000 lowmem: direct linear mapping of RAM into the kernel (virt = phys + PAGE_OFFSET); capped at 896 MiB HIGH_MEMORY: first virtual address not linearly mapped (end of lowmem) pkmap: permanent mappings for h...
