[Micro Learning] Interrupt Stack in Zephyr RISC V

Introduction The _interrupt_stack is a critical component in managing interrupt handling within the Zephyr RTOS for the RISCV32 architecture. Its primary purpose is to provide a dedicated and isolated stack for Interrupt Service Routines (ISRs), ensuring that they operate independently of thread-specific stacks. This separation is vital for preventing data corruption, improving real-time performance, and…
