bfq_set_budget

Name:Set the maximum time for the in-service queue to consume its* budget. This prevents seeky processes from lowering the throughput.* In practice, a time-slice service scheme is used with seeky* processes.

Proto:static void bfq_set_budget_timeout(struct bfq_data *bfqd, struct bfq_queue *bfqq)

Type:void

Parameter:

Type	Parameter	Name
struct bfq_data *	bfqd
struct bfq_queue *	bfqq

2880

If current maximum weight-raising time for this queue == Maximum weight-raising duration for soft real-time processes Then timeout_coeff = 1

2882

Else timeout_coeff = weight of the queue / original weight, used to implement weight boosting

2885

beginning of the last budget = ktime_get()

2887

udget expiration (in jiffies) = jiffies + * Timeout for bfq_queues to consume their budget; used to * prevent seeky queues from imposing long latencies to * sequential or quasi-sequential ones (this also implies that * seeky queues cannot receive guarantees in the service * domain; after a timeout * timeout_coeff
