| D | Kconfig.hz | 9 Allows the configuration of the timer frequency. It is customary
10 to have the timer interrupt run at 1000 Hz but 100 Hz may be more
13 contention and cacheline bounces as a result of timer interrupts.
14 Note that the timer interrupt occurs on each processor in an SMP
15 environment leading to NR_CPUS * HZ number of timer interrupts
24 too many timer interrupts are occurring.
