preemptive的kernel允许被更高优先级的进程打断。 抢占内核和非抢占内核Linux都是通过switch_to宏,非抢占内核linux在内核态,不允许切换内核。 例子1:进程A进入kernel模式下的异常处理函数,此时来了有一个中断,进入ISP。 对于preemptive kernel,ISP返回后会切换到别的进程。 对于nonpreemptive kernel,ISP返回后不会切换...
The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work...
While discard_max_hw_bytes is the hardware limit for the device, this setting is the software limit. Some devices exhibit large latencies when large discards are issued, setting this value lower will make Linux issue smaller discards and potentially help reduce latencies induced by large discard o...
