div64_s64 | div64_s64 - signed 64bit divide with 64bit divisor*@dividend: 64bit dividend*@divisor: 64bit divisor |
aperfmperf_snapshot_khz | aperfmperf_snapshot_khz()* On the current CPU, snapshot APERF, MPERF, and jiffies* unless we already did it within 10ms* calculate kHz, save snapshot |
to_ratio | |
proc_sched_show_task | |
window_update | PSI growth tracking window update and growth calculation routine.* This approximates a sliding tracking window by interpolating* partially elapsed windows using historical growth data from the* previous intervals |
em_create_pd | |
timekeeping_adjust | Adjust the timekeeper's multiplier to the correct frequency* and also to reduce the accumulated error value. |
___bpf_prog_run | __bpf_prog_run - run eBPF program on a given context*@regs: is the array of MAX_BPF_EXT_REG eBPF pseudo-registers*@insn: is the array of eBPF instructions*@stack: is the eBPF storage stack* Decode and execute eBPF instructions. |
perf_calculate_period | |
perf_swevent_set_period | We directly increment event->count and keep a second value in* is kept in the range [-sample_period, 0] so that we can use the* sign as trigger. |
get_scan_count | Determine how aggressively the anon and file LRU lists should be* scanned |
latency_sum_ok | |
iolat_update_total_lat_avg | |
check_scale_change | Check our parent and see if the scale cookie has changed. |
