Over time, several useful features have been +ported from CFQ as well (details in the changelog in README.BFQ). A +(bfq_)queue is associated to each task doing I/O on a device, and each +time a scheduling decision has to be made a queue is selected and served +until it expires. + + - Slices are given in the service domain: tasks are assigned + budgets, measured in number of sectors. Once got the disk, a task + must however consume its assigned budget within a configurable + maximum time (by default, the maximum possible value of the + budgets is automatically computed to comply with this timeout). + This allows the desired latency vs "throughput boosting" tradeoff + to be set. + + - Budgets are scheduled according to a variant of WF2Q+, implemented + using an augmented rb-tree to take eligibility into account while + preserving an O(log N) overall complexity. + + - A low-latency tunable is provided; if enabled, both interactive + and soft real-time applications are guaranteed a very low latency. + + - Latency guarantees are preserved also in the presence of NCQ. + + - Also with flash-based devices, a high throughput is achieved + while still preserving latency guarantees. + + - BFQ features Early Queue Merge (EQM), a sort of fusion of the + cooperating-queue-merging and the preemption mechanisms present + in CFQ. EQM is in fact a unified mechanism that tries to get a + sequential read pattern, and hence a high throughput, with any + set of processes performing interleaved I/O over a contiguous + sequence of sectors. + + - BFQ supports full hierarchical scheduling, exporting a cgroups + interface. Since each node has a full scheduler, each group can + be assigned its own weight. + + - If the cgroups interface is not used, only I/O priorities can be + assigned to processes, with ioprio values mapped to weights + with the relation weight = IOPRIO_BE_NR - ioprio. + + - ioprio classes are served in strict priority order, i.e., lower + priority queues are not served as long as there are higher + priority queues. Among queues in the same class the bandwidth is + distributed in proportion to the weight of each queue. A very + thin extra bandwidth is however guaranteed to the Idle class, to + prevent it from starving. + +Signed-off-by: Paolo Valente +Signed-off-by: Arianna Avanzini +--- + block/bfq-cgroup.c | 930 ++++++++++++ + block/bfq-ioc.c | 36 + + block/bfq-iosched.c | 3887 +++++++++++++++++++++++++++++++++++++++++++++++++++ + block/bfq-sched.c | 1207 ++++++++++++++++ + block/bfq.h | 773 ++++++++++ + 5 files changed, 6833 insertions(+) + create mode 100644 block/bfq-cgroup.c + create mode 100644 block/bfq-ioc.c + create mode 100644 block/bfq-iosched.c + create mode 100644 block/bfq-sched.c + create mode 100644 block/bfq.h + +diff --git a/block/bfq-cgroup.c b/block/bfq-cgroup.c +new file mode 100644 +index 0000000..eb140eb +--- /dev/null ++++ block/bfq-cgroup.c +@@ -0,0 +1,930 @@ ++/* ++ * BFQ: CGROUPS support. ++ * ++ * Based on ideas and code from CFQ: ++ * Copyright (C) 2003 Jens Axboe ++ * ++ * Copyright (C) 2008 Fabio Checconi ++ * Paolo Valente ++ * ++ * Copyright (C) 2010 Paolo Valente ++ * ++ * Licensed under the GPL-2 as detailed in the accompanying COPYING.BFQ ++ * file. ++ */ ++ ++#ifdef CONFIG_CGROUP_BFQIO ++ ++static DEFINE_MUTEX(bfqio_mutex); ++ ++static bool bfqio_is_removed(struct bfqio_cgroup *bgrp) ++{ ++ return bgrp ? !bgrp->online : false; ++} ++ ++static struct bfqio_cgroup bfqio_root_cgroup = { ++ .weight = BFQ_DEFAULT_GRP_WEIGHT, ++ .ioprio = BFQ_DEFAULT_GRP_IOPRIO, ++ .ioprio_class = BFQ_DEFAULT_GRP_CLASS, ++}; ++ ++static inline void bfq_init_entity(struct bfq_entity *entity, ++ struct bfq_group *bfqg) ++{ ++ entity->weight = entity->new_weight; ++ entity->orig_weight = entity->new_weight; ++ entity->ioprio = entity->new_ioprio; ++ entity->ioprio_class = entity->new_ioprio_class; ++ entity->parent = bfqg->my_entity; ++ entity->sched_data = &bfqg->sched_data; ++} ++ ++static struct bfqio_cgroup *css_to_bfqio(struct cgroup_subsys_state *css) ++{ ++ return css ? container_of(css, struct bfqio_cgroup, css) : NULL; ++} ++ ++/* ++ * Search the bfq_group for bfqd into the hash table (by now only a list) ++ * of bgrp.

But BFQ assigns budgets, ++ * measured in number of sectors, to processes instead of time slices. The ++ * device is not granted to the in-service process for a given time slice, ++ * but until it has exhausted its assigned budget. This change from the time ++ * to the service domain allows BFQ to distribute the device throughput ++ * among processes as desired, without any distortion due to ZBR, workload ++ * fluctuations or other factors. BFQ uses an ad hoc internal scheduler, ++ * called B-WF2Q+, to schedule processes according to their budgets. More ++ * precisely, BFQ schedules queues associated to processes. Thanks to the ++ * accurate policy of B-WF2Q+, BFQ can afford to assign high budgets to ++ * I/O-bound processes issuing sequential requests (to boost the ++ * throughput), and yet guarantee a low latency to interactive and soft ++ * real-time applications. ++ * ++ * BFQ is described in [1], where also a reference to the initial, more ++ * theoretical paper on BFQ can be found. The interested reader can find ++ * in the latter paper full details on the main algorithm, as well as ++ * formulas of the guarantees and formal proofs of all the properties. ++ * With respect to the version of BFQ presented in these papers, this ++ * implementation adds a few more heuristics, such as the one that ++ * guarantees a low latency to soft real-time applications, and a ++ * hierarchical extension based on H-WF2Q+. ++ * ++ * B-WF2Q+ is based on WF2Q+, that is described in [2], together with ++ * H-WF2Q+, while the augmented tree used to implement B-WF2Q+ with O(log N) ++ * complexity derives from the one introduced with EEVDF in [3]. ++ * ++ * [1] P.

In this comment we describe, firstly, ++ * the reasons why this fact holds, and, secondly, the next function, which ++ * implements the main steps needed to properly mark these queues so that ++ * they can then be treated in a different way. ++ * ++ * As for the terminology, we say that a queue becomes active, i.e., ++ * switches from idle to backlogged, either when it is created (as a ++ * consequence of the arrival of an I/O request), or, if already existing, ++ * when a new request for the queue arrives while the queue is idle. ++ * Bursts of activations, i.e., activations of different queues occurring ++ * shortly after each other, are typically caused by services or applications ++ * that spawn or reactivate many parallel threads/processes. Examples are ++ * systemd during boot or git grep. ++ * ++ * These services or applications benefit mostly from a high throughput: ++ * the quicker the requests of the activated queues are cumulatively served, ++ * the sooner the target job of these queues gets completed. As a consequence, ++ * weight-raising any of these queues, which also implies idling the device ++ * for it, is almost always counterproductive: in most cases it just lowers ++ * throughput. ++ * ++ * On the other hand, a burst of activations may be also caused by the start ++ * of an application that does not consist in a lot of parallel I/O-bound ++ * threads. In fact, with a complex application, the burst may be just a ++ * consequence of the fact that several processes need to be executed to ++ * start-up the application. To start an application as quickly as possible, ++ * the best thing to do is to privilege the I/O related to the application ++ * with respect to all other I/O. Therefore, the best strategy to start as ++ * quickly as possible an application that causes a burst of activations is ++ * to weight-raise all the queues activated during the burst. This is the ++ * exact opposite of the best strategy for the other type of bursts. ++ * ++ * In the end, to take the best action for each of the two cases, the two ++ * types of bursts need to be distinguished. Fortunately, this seems ++ * relatively easy to do, by looking at the sizes of the bursts. In ++ * particular, we found a threshold such that bursts with a larger size ++ * than that threshold are apparently caused only by services or commands ++ * such as systemd or git grep. For brevity, hereafter we call just 'large' ++ * these bursts. BFQ *does not* weight-raise queues whose activations occur ++ * in a large burst. In addition, for each of these queues BFQ performs or ++ * does not perform idling depending on which choice boosts the throughput ++ * most. The exact choice depends on the device and request pattern at ++ * hand. ++ * ++ * Turning back to the next function, it implements all the steps needed ++ * to detect the occurrence of a large burst and to properly mark all the ++ * queues belonging to it (so that they can then be treated in a different ++ * way). This goal is achieved by maintaining a special "burst list" that ++ * holds, temporarily, the queues that belong to the burst in progress. The ++ * list is then used to mark these queues as belonging to a large burst if ++ * the burst does become large. The main steps are the following. ++ * ++ * . when the very first queue is activated, the queue is inserted into the ++ * list (as it could be the first queue in a possible burst) ++ * ++ * . if the current burst has not yet become large, and a queue Q that does ++ * not yet belong to the burst is activated shortly after the last time ++ * at which a new queue entered the burst list, then the function appends ++ * Q to the burst list ++ * ++ * . if, as a consequence of the previous step, the burst size reaches ++ * the large-burst threshold, then ++ * ++ * . all the queues in the burst list are marked as belonging to a ++ * large burst ++ * ++ * . the burst list is deleted; in fact, the burst list already served ++ * its purpose (keeping temporarily track of the queues in a burst, ++ * so as to be able to mark them as belonging to a large burst in the ++ * previous sub-step), and now is not needed any more ++ * ++ * . the device enters a large-burst mode ++ * ++ * . if a queue Q that does not belong to the burst is activated while ++ * the device is in large-burst mode and shortly after the last time ++ * at which a queue either entered the burst list or was marked as ++ * belonging to the current large burst, then Q is immediately marked ++ * as belonging to a large burst. ++ * ++ * . if a queue Q that does not belong to the burst is activated a while ++ * later, i.e., not shortly after, than the last time at which a queue ++ * either entered the burst list or was marked as belonging to the ++ * current large burst, then the current burst is deemed as finished and: ++ * ++ * . the large-burst mode is reset if set ++ * ++ * . the burst list is emptied ++ * ++ * .

After that, the application may issue a new batch, ++ * and so on. ++ * For this reason the next function is invoked to compute ++ * soft_rt_next_start only for applications that meet this requirement, ++ * whereas soft_rt_next_start is set to infinity for applications that do ++ * not. ++ * ++ * Unfortunately, even a greedy application may happen to behave in an ++ * isochronous way if the CPU load is high.

For this reason, the return value of this function plays a ++ * critical role for both throughput boosting and service guarantees. The ++ * return value is computed through a logical expression. In this rather ++ * long comment, we try to briefly describe all the details and motivations ++ * behind the components of this logical expression. ++ * ++ * First, the expression is false if bfqq is not sync, or if: bfqq happened ++ * to become active during a large burst of queue activations, and the ++ * pattern of requests bfqq contains boosts the throughput if bfqq is ++ * expired. In fact, queues that became active during a large burst benefit ++ * only from throughput, as discussed in the comments to bfq_handle_burst. ++ * In this respect, expiring bfqq certainly boosts the throughput on NCQ- ++ * capable flash-based devices, whereas, on rotational devices, it boosts ++ * the throughput only if bfqq contains random requests. ++ * ++ * On the opposite end, if (a) bfqq is sync, (b) the above burst-related ++ * condition does not hold, and (c) bfqq is being weight-raised, then the ++ * expression always evaluates to true, as device idling is instrumental ++ * for preserving low-latency guarantees (see [1]). If, instead, conditions ++ * (a) and (b) do hold, but (c) does not, then the expression evaluates to ++ * true only if: (1) bfqq is I/O-bound and has a non-null idle window, and ++ * (2) at least one of the following two conditions holds. ++ * The first condition is that the device is not performing NCQ, because ++ * idling the device most certainly boosts the throughput if this condition ++ * holds and bfqq is I/O-bound and has been granted a non-null idle window. ++ * The second compound condition is made of the logical AND of two components. ++ * ++ * The first component is true only if there is no weight-raised busy ++ * queue. This guarantees that the device is not idled for a sync non- ++ * weight-raised queue when there are busy weight-raised queues. The former ++ * is then expired immediately if empty. Combined with the timestamping ++ * rules of BFQ (see [1] for details), this causes sync non-weight-raised ++ * queues to get a lower number of requests served, and hence to ask for a ++ * lower number of requests from the request pool, before the busy weight- ++ * raised queues get served again. ++ * ++ * This is beneficial for the processes associated with weight-raised ++ * queues, when the request pool is saturated (e.g., in the presence of ++ * write hogs). In fact, if the processes associated with the other queues ++ * ask for requests at a lower rate, then weight-raised processes have a ++ * higher probability to get a request from the pool immediately (or at ++ * least soon) when they need one. Hence they have a higher probability to ++ * actually get a fraction of the disk throughput proportional to their ++ * high weight. This is especially true with NCQ-capable drives, which ++ * enqueue several requests in advance and further reorder internally- ++ * queued requests. ++ * ++ * In the end, mistreating non-weight-raised queues when there are busy ++ * weight-raised queues seems to mitigate starvation problems in the ++ * presence of heavy write workloads and NCQ, and hence to guarantee a ++ * higher application and system responsiveness in these hostile scenarios. ++ * ++ * If the first component of the compound condition is instead true, i.e., ++ * there is no weight-raised busy queue, then the second component of the ++ * compound condition takes into account service-guarantee and throughput ++ * issues related to NCQ (recall that the compound condition is evaluated ++ * only if the device is detected as supporting NCQ). ++ * ++ * As for service guarantees, allowing the drive to enqueue more than one ++ * request at a time, and hence delegating de facto final scheduling ++ * decisions to the drive's internal scheduler, causes loss of control on ++ * the actual request service order. In this respect, when the drive is ++ * allowed to enqueue more than one request at a time, the service ++ * distribution enforced by the drive's internal scheduler is likely to ++ * coincide with the desired device-throughput distribution only in the ++ * following, perfectly symmetric, scenario: ++ * 1) all active queues have the same weight, ++ * 2) all active groups at the same level in the groups tree have the same ++ * weight, ++ * 3) all active groups at the same level in the groups tree have the same ++ * number of children. ++ * ++ * Even in such a scenario, sequential I/O may still receive a preferential ++ * treatment, but this is not likely to be a big issue with flash-based ++ * devices, because of their non-dramatic loss of throughput with random ++ * I/O. Things do differ with HDDs, for which additional care is taken, as ++ * explained after completing the discussion for flash-based devices. ++ * ++ * Unfortunately, keeping the necessary state for evaluating exactly the ++ * above symmetry conditions would be quite complex and time-consuming. ++ * Therefore BFQ evaluates instead the following stronger sub-conditions, ++ * for which it is much easier to maintain the needed state: ++ * 1) all active queues have the same weight, ++ * 2) all active groups have the same weight, ++ * 3) all active groups have at most one active child each. ++ * In particular, the last two conditions are always true if hierarchical ++ * support and the cgroups interface are not enabled, hence no state needs ++ * to be maintained in this case. ++ * ++ * According to the above considerations, the second component of the ++ * compound condition evaluates to true if any of the above symmetry ++ * sub-condition does not hold, or the device is not flash-based. Therefore, ++ * if also the first component is true, then idling is allowed for a sync ++ * queue. These are the only sub-conditions considered if the device is ++ * flash-based, as, for such a device, it is sensible to force idling only ++ * for service-guarantee issues. In fact, as for throughput, idling ++ * NCQ-capable flash-based devices would not boost the throughput even ++ * with sequential I/O; rather it would lower the throughput in proportion ++ * to how fast the device is. In the end, (only) if all the three ++ * sub-conditions hold and the device is flash-based, the compound ++ * condition evaluates to false and therefore no idling is performed. ++ * ++ * As already said, things change with a rotational device, where idling ++ * boosts the throughput with sequential I/O (even with NCQ). Hence, for ++ * such a device the second component of the compound condition evaluates ++ * to true also if the following additional sub-condition does not hold: ++ * the queue is constantly seeky. Unfortunately, this different behavior ++ * with respect to flash-based devices causes an additional asymmetry: if ++ * some sync queues enjoy idling and some other sync queues do not, then ++ * the latter get a low share of the device throughput, simply because the ++ * former get many requests served after being set as in service, whereas ++ * the latter do not. As a consequence, to guarantee the desired throughput ++ * distribution, on HDDs the compound expression evaluates to true (and ++ * hence device idling is performed) also if the following last symmetry ++ * condition does not hold: no other queue is benefiting from idling. Also ++ * this last condition is actually replaced with a simpler-to-maintain and ++ * stronger condition: there is no busy queue which is not constantly seeky ++ * (and hence may also benefit from idling). ++ * ++ * To sum up, when all the required symmetry and throughput-boosting ++ * sub-conditions hold, the second component of the compound condition ++ * evaluates to false, and hence no idling is performed. This helps to ++ * keep the drives' internal queues full on NCQ-capable devices, and hence ++ * to boost the throughput, without causing 'almost' any loss of service ++ * guarantees. The 'almost' follows from the fact that, if the internal ++ * queue of one such device is filled while all the sub-conditions hold, ++ * but at some point in time some sub-condition stops to hold, then it may ++ * become impossible to let requests be served in the new desired order ++ * until all the requests already queued in the device have been served. ++ */ ++static inline bool bfq_bfqq_must_not_expire(struct bfq_queue *bfqq) ++{ ++ struct bfq_data *bfqd = bfqq->bfqd; ++#ifdef CONFIG_CGROUP_BFQIO ++#define symmetric_scenario (!bfqd->active_numerous_groups && \ ++ !bfq_differentiated_weights(bfqd)) ++#else ++#define symmetric_scenario (!bfq_differentiated_weights(bfqd)) ++#endif ++#define cond_for_seeky_on_ncq_hdd (bfq_bfqq_constantly_seeky(bfqq) && \ ++ bfqd->busy_in_flight_queues == \ ++ bfqd->const_seeky_busy_in_flight_queues) ++ ++#define cond_for_expiring_in_burst (bfq_bfqq_in_large_burst(bfqq) && \ ++ bfqd->hw_tag && \ ++ (blk_queue_nonrot(bfqd->queue) || \ ++ bfq_bfqq_constantly_seeky(bfqq))) ++ ++/* ++ * Condition for expiring a non-weight-raised queue (and hence not idling ++ * the device). ++ */ ++#define cond_for_expiring_non_wr (bfqd->hw_tag && \ ++ (bfqd->wr_busy_queues > 0 || \ ++ (symmetric_scenario && \ ++ (blk_queue_nonrot(bfqd->queue) || \ ++ cond_for_seeky_on_ncq_hdd)))) ++ ++ return bfq_bfqq_sync(bfqq) && ++ !cond_for_expiring_in_burst && ++ (bfqq->wr_coeff > 1 || ++ (bfq_bfqq_IO_bound(bfqq) && bfq_bfqq_idle_window(bfqq) && ++ !cond_for_expiring_non_wr) ++ ); ++} ++ ++/* ++ * If the in-service queue is empty but sync, and the function ++ * bfq_bfqq_must_not_expire returns true, then: ++ * 1) the queue must remain in service and cannot be expired, and ++ * 2) the disk must be idled to wait for the possible arrival of a new ++ * request for the queue. ++ * See the comments to the function bfq_bfqq_must_not_expire for the reasons ++ * why performing device idling is the best choice to boost the throughput ++ * and preserve service guarantees when bfq_bfqq_must_not_expire itself ++ * returns true. ++ */ ++static inline bool bfq_bfqq_must_idle(struct bfq_queue *bfqq) ++{ ++ struct bfq_data *bfqd = bfqq->bfqd; ++ ++ return RB_EMPTY_ROOT(&bfqq->sort_list) && bfqd->bfq_slice_idle != 0 && ++ bfq_bfqq_must_not_expire(bfqq); ++} ++ ++/* ++ * Select a queue for service.

There are two +typical cases: in the first case, processes read fixed-size chunks of +data at a fixed distance from each other, while in the second case processes +may read variable-size chunks at variable distances. The latter case occurs +for example with QEMU, which splits the I/O generated by the guest into +multiple chunks, and lets these chunks be served by a pool of cooperating +processes, iteratively assigning the next chunk of I/O to the first +available process. CFQ uses actual queue merging for the first type of +rocesses, whereas it uses preemption to get a sequential read pattern out +of the read requests performed by the second type of processes. In the end +it uses two different mechanisms to achieve the same goal: boosting the +throughput with interleaved I/O. + +This patch introduces Early Queue Merge (EQM), a unified mechanism to get a +sequential read pattern with both types of processes. The main idea is +checking newly arrived requests against the next request of the active queue +both in case of actual request insert and in case of request merge. By doing +so, both the types of processes can be handled by just merging their queues. +EQM is then simpler and more compact than the pair of mechanisms used in +CFQ. + +Finally, EQM also preserves the typical low-latency properties of BFQ, by +properly restoring the weight-raising state of a queue when it gets back to +a non-merged state. + +Signed-off-by: Mauro Andreolini +Signed-off-by: Arianna Avanzini +Signed-off-by: Paolo Valente +--- + block/bfq-iosched.c | 743 +++++++++++++++++++++++++++++++++++++--------------- + block/bfq-sched.c | 28 -- + block/bfq.h | 54 +++- + 3 files changed, 573 insertions(+), 252 deletions(-) + +diff --git a/block/bfq-iosched.c b/block/bfq-iosched.c +index b919b03..bbfb4e1 100644 +--- a/block/bfq-iosched.c ++++ b/block/bfq-iosched.c +@@ -571,6 +571,57 @@ static inline unsigned int bfq_wr_duration(struct bfq_data *bfqd) + return dur; + } + ++static inline unsigned ++bfq_bfqq_cooperations(struct bfq_queue *bfqq) ++{ ++ return bfqq->bic ?
