函数名称：q_bfqq_charge_time - charge an amount of service equivalent to the length* of the time interval during which bfqq has been in* service
函数原型：void bfq_bfqq_charge_time(struct bfq_data *bfqd, struct bfq_queue *bfqq, unsigned long time_ms)
返回类型：void
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| struct bfq_data * | bfqd | |
| struct bfq_queue * | bfqq | |
| unsigned long | time_ms |
| 889 | timeout_ms等于Convert jiffies to milliseconds and back.* Avoid unnecessary multiplications/divisions in the* two most common HZ cases: |
| 890 | bounded_time_ms等于两数取小(time_ms, timeout_ms) |
| 891 | serv_to_charge_for_time等于 maximum budget allotted to a bfq_queue before rescheduling 乘bounded_time_ms除timeout_ms |
| 893 | tot_serv_to_charge等于两数取大(serv_to_charge_for_time, amount of service received during the last service slot ) |
| 896 | 如果tot_serv_to_charge大于 budget, used also to calculate F_i: F_i = S_i + @budget / @weight 则 budget, used also to calculate F_i: F_i = S_i + @budget / @weight 等于tot_serv_to_charge |
