linux kernel (2) 썸네일형 리스트형 [RISC-V]: Interrupt handling workflow in Linux kernel Interrupt handling routines are architecture-dependent. The way interrupts are managed and processed can vary significantly between different computer architectures. Interrupt handling routines can be different between RISC-V and Armv8. Understanding interrupt handling routines is crucial when dealing with real-time operating systems (RTOS) and the Linux kernel. Since RTOS and Linux kernel rely ..
