33 | * Description: | |
34 | * The perf_counters cache statistics have N, or | |
35 | * perf_history_size, samples. The default is | |
36 | * one. | |
37 | * | |
38 | * Every perf_time_interval_secs the (first) | |
39 | * samples are reset. | |
40 | * | |
41 | * If N is greater than one, the "current" set | |
42 | * of samples is reset, and the samples from the | |
43 | * other N-1 intervals remain available. | |

59 | * memory segment used for communication | |
60 | * between the kernel module and userspace. | |
61 | * Slots are requested and waited for, | |
62 | * the wait times out after slot_timeout_secs. | |
