-config PREEMPT
- bool "Preemptible Kernel"
- ---help---
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- This allows applications to run more reliably even when the system is
- under load. On contrary it may also break your drivers and add
- priority inheritance problems to your system. Don't select it if
- you rely on a stable system or have slightly obscure hardware.
- It's also not very well tested on x86-64 currently.
- You have been warned.
-
- Say Y here if you are feeling brave and building a kernel for a
- desktop, embedded or real-time system. Say N if you are unsure.

-config PREEMPT_BKL
- bool "Preempt The Big Kernel Lock"
- depends on PREEMPT
- default y
- help
- This option reduces the latency of the kernel by making the
- big kernel lock preemptible.

- Say Y here if you are building a kernel for a desktop system.
- Say N if you are unsure.
