Upon successful ++ * reservation they are removed from the lru list. This stops a reserved buffer ++ * from being evicted. However the lru spinlock is released between the time ++ * a buffer is selected for eviction and the time it is reserved. ++ * Therefore a check is made when a buffer is reserved for eviction, that it ++ * is still the first buffer in the lru list, before it is removed from the ++ * list. @check_lru == 1 forces this check.

If upon call of this function, the buffer object is already ++ * reserved, the validation sequence is checked against the validation ++ * sequence of the process currently reserving the buffer, ++ * and if the current validation sequence is greater than that of the process ++ * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps ++ * waiting for the buffer to become unreserved, after which it retries reserving. ++ * The caller should, when receiving an -EAGAIN error ++ * release all its buffer reservations, wait for @bo to become unreserved, and ++ * then rerun the validation with the same validation sequence. This procedure ++ * will always guarantee that the process with the lowest validation sequence ++ * will eventually succeed, preventing both deadlocks and starvation. ++ * ++ * Returns: ++ * -EAGAIN: The reservation may cause a deadlock.

CPUIDLE ++ * provides us this duration in the "target_residency" field. So all that we ++ * need is a good prediction of how long we'll be idle. Like the traditional ++ * menu governor, we start with the actual known "next timer event" time. ++ * ++ * Since there are other source of wakeups (interrupts for example) than ++ * the next timer event, this estimation is rather optimistic. To get a ++ * more realistic estimate, a correction factor is applied to the estimate, ++ * that is based on historic behavior. For example, if in the past the actual ++ * duration always was 50% of the next timer tick, the correction factor will ++ * be 0.5. ++ * ++ * menu uses a running average for this correction factor, however it uses a ++ * set of factors, not just a single factor. This stems from the realization ++ * that the ratio is dependent on the order of magnitude of the expected ++ * duration; if we expect 500 milliseconds of idle time the likelihood of ++ * getting an interrupt very early is much higher than if we expect 50 micro ++ * seconds of idle time. A second independent factor that has big impact on ++ * the actual factor is if there is (disk) IO outstanding or not. ++ * (as a special twist, we consider every sleep longer than 50 milliseconds ++ * as perfect; there are no power gains for sleeping longer than this) ++ * ++ * For these two reasons we keep an array of 12 independent factors, that gets ++ * indexed based on the magnitude of the expected duration as well as the ++ * "is IO outstanding" property. ++ * ++ * Limiting Performance Impact ++ * --------------------------- ++ * C states, especially those with large exit latencies, can have a real ++ * noticable impact on workloads, which is not acceptable for most sysadmins, ++ * and in addition, less performance has a power price of its own. ++ * ++ * As a general rule of thumb, menu assumes that the following heuristic ++ * holds: ++ * The busier the system, the less impact of C states is acceptable ++ * ++ * This rule-of-thumb is implemented using a performance-multiplier: ++ * If the exit latency times the performance multiplier is longer than ++ * the predicted duration, the C state is not considered a candidate ++ * for selection due to a too high performance impact. So the higher ++ * this multiplier is, the longer we need to be idle to pick a deep C ++ * state, and thus the less likely a busy CPU will hit such a deep ++ * C state. ++ * ++ * Two factors are used in determing this multiplier: ++ * a value of 10 is added for each point of "per cpu load average" we have. ++ * a value of 5 points is added for each process that is waiting for ++ * IO on this CPU. ++ * (these values are experimentally determined) ++ * ++ * The load average factor gives a longer term (few seconds) input to the ++ * decision, while the iowait value gives a cpu local instantanious input. ++ * The iowait factor may look low, but realize that this is also already ++ * represented in the system load average. ++ * ++ */ + + struct menu_device { + int last_state_idx;
