19939 |
-+What is it? |
19940 |
-+----------- |
19941 |
-+ |
19942 |
-+The framebuffer decorations are a kernel feature which allows displaying a |
19943 |
-+background picture on selected consoles. |
19944 |
-+ |
19945 |
-+What do I need to get it to work? |
19946 |
-+--------------------------------- |
19947 |
-+ |
19948 |
-+To get fbcondecor up-and-running you will have to: |
19949 |
-+ 1) get a copy of splashutils [1] or a similar program |
19950 |
-+ 2) get some fbcondecor themes |
19951 |
-+ 3) build the kernel helper program |
19952 |
-+ 4) build your kernel with the FB_CON_DECOR option enabled. |
19953 |
-+ |
19954 |
-+To get fbcondecor operational right after fbcon initialization is finished, you |
19955 |
-+will have to include a theme and the kernel helper into your initramfs image. |
19956 |
-+Please refer to splashutils documentation for instructions on how to do that. |
19957 |
-+ |
19958 |
-+[1] The splashutils package can be downloaded from: |
19959 |
-+ http://github.com/alanhaggai/fbsplash |
19960 |
-+ |
19961 |
-+The userspace helper |
19962 |
-+-------------------- |
19963 |
-+ |
19964 |
-+The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the |
19965 |
-+kernel whenever an important event occurs and the kernel needs some kind of |
19966 |
-+job to be carried out. Important events include console switches and video |
19967 |
-+mode switches (the kernel requests background images and configuration |
19968 |
-+parameters for the current console). The fbcondecor helper must be accessible at |
19969 |
-+all times. If it's not, fbcondecor will be switched off automatically. |
19970 |
-+ |
19971 |
-+It's possible to set path to the fbcondecor helper by writing it to |
19972 |
-+/proc/sys/kernel/fbcondecor. |
19973 |
-+ |
19974 |
-+***************************************************************************** |
19975 |
-+ |
19976 |
-+The information below is mostly technical stuff. There's probably no need to |
19977 |
-+read it unless you plan to develop a userspace helper. |
19978 |
-+ |
19979 |
-+The fbcondecor protocol |
19980 |
-+----------------------- |
19981 |
-+ |
19982 |
-+The fbcondecor protocol defines a communication interface between the kernel and |
19983 |
-+the userspace fbcondecor helper. |
19984 |
-+ |
19985 |
-+The kernel side is responsible for: |
19986 |
-+ |
19987 |
-+ * rendering console text, using an image as a background (instead of a |
19988 |
-+ standard solid color fbcon uses), |
19989 |
-+ * accepting commands from the user via ioctls on the fbcondecor device, |
19990 |
-+ * calling the userspace helper to set things up as soon as the fb subsystem |
19991 |
-+ is initialized. |
19992 |
-+ |
19993 |
-+The userspace helper is responsible for everything else, including parsing |
19994 |
-+configuration files, decompressing the image files whenever the kernel needs |
19995 |
-+it, and communicating with the kernel if necessary. |
19996 |
-+ |
19997 |
-+The fbcondecor protocol specifies how communication is done in both ways: |
19998 |
-+kernel->userspace and userspace->helper. |
19999 |
-+ |
20000 |
-+Kernel -> Userspace |
20001 |
-+------------------- |
20002 |
-+ |
20003 |
-+The kernel communicates with the userspace helper by calling it and specifying |
20004 |
-+the task to be done in a series of arguments. |
20005 |
-+ |
20006 |
-+The arguments follow the pattern: |
20007 |
-+<fbcondecor protocol version> <command> <parameters> |
20008 |
-+ |
20009 |
-+All commands defined in fbcondecor protocol v2 have the following parameters: |
20010 |
-+ virtual console |
20011 |
-+ framebuffer number |
20012 |
-+ theme |
20013 |
-+ |
20014 |
-+Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the |
20015 |
-+framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. |
20016 |
-+ |
20017 |
-+Fbcondecor protocol v2 specifies the following commands: |
20018 |
-+ |
20019 |
-+getpic |
20020 |
-+------ |
20021 |
-+ The kernel issues this command to request image data. It's up to the |
20022 |
-+ userspace helper to find a background image appropriate for the specified |
20023 |
-+ theme and the current resolution. The userspace helper should respond by |
20024 |
-+ issuing the FBIOCONDECOR_SETPIC ioctl. |
20025 |
-+ |
20026 |
-+init |
20027 |
-+---- |
20028 |
-+ The kernel issues this command after the fbcondecor device is created and |
20029 |
-+ the fbcondecor interface is initialized. Upon receiving 'init', the userspace |
20030 |
-+ helper should parse the kernel command line (/proc/cmdline) or otherwise |
20031 |
-+ decide whether fbcondecor is to be activated. |
20032 |
-+ |
20033 |
-+ To activate fbcondecor on the first console the helper should issue the |
20034 |
-+ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands, |
20035 |
-+ in the above-mentioned order. |
20036 |
-+ |
20037 |
-+ When the userspace helper is called in an early phase of the boot process |
20038 |
-+ (right after the initialization of fbcon), no filesystems will be mounted. |
20039 |
-+ The helper program should mount sysfs and then create the appropriate |
20040 |
-+ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get |
20041 |
-+ current display settings and to be able to communicate with the kernel side. |
20042 |
-+ It should probably also mount the procfs to be able to parse the kernel |
20043 |
-+ command line parameters. |
20044 |
-+ |
20045 |
-+ Note that the console sem is not held when the kernel calls fbcondecor_helper |
20046 |
-+ with the 'init' command. The fbcondecor helper should perform all ioctls with |
20047 |
-+ origin set to FBCON_DECOR_IO_ORIG_USER. |
20048 |
-+ |
20049 |
-+modechange |
20050 |
-+---------- |
20051 |
-+ The kernel issues this command on a mode change. The helper's response should |
20052 |
-+ be similar to the response to the 'init' command. Note that this time the |
20053 |
-+ console sem is held and all ioctls must be performed with origin set to |
20054 |
-+ FBCON_DECOR_IO_ORIG_KERNEL. |
20055 |
-+ |
20056 |
-+ |
20057 |
-+Userspace -> Kernel |
20058 |
-+------------------- |
20059 |
-+ |
20060 |
-+Userspace programs can communicate with fbcondecor via ioctls on the |
20061 |
-+fbcondecor device. These ioctls are to be used by both the userspace helper |
20062 |
-+(called only by the kernel) and userspace configuration tools (run by the users). |
20063 |
-+ |
20064 |
-+The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL |
20065 |
-+when doing the appropriate ioctls. All userspace configuration tools should |
20066 |
-+use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin |
20067 |
-+field when performing ioctls from the kernel helper will most likely result |
20068 |
-+in a console deadlock. |
20069 |
-+ |
20070 |
-+FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console |
20071 |
-+semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire |
20072 |
-+the console sem. |
20073 |
-+ |
20074 |
-+The framebuffer console decoration provides the following ioctls (all defined in |
20075 |
-+linux/fb.h): |

-+If called for consoles other than the current foreground one, the picture data |
20082 |
-+will be ignored. |
20083 |
-+ |
20084 |
-+If the current virtual console is running in a 8-bpp mode, the cmap substruct |
20085 |
-+of fb_image has to be filled appropriately: start should be set to 16 (first |
20086 |
-+16 colors are reserved for fbcon), len to a value <= 240 and red, green and |
20087 |
-+blue should point to valid cmap data. The transp field is ingored. The fields |
20088 |
-+dx, dy, bg_color, fg_color in fb_image are ignored as well. |

20108 |
-+ |
20109 |
-+Info on used structures: |
20110 |
-+ |
20111 |
-+Definition of struct vc_decor can be found in linux/console_decor.h. It's |
20112 |
-+heavily commented. Note that the 'theme' field should point to a string |
20113 |
-+no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is |
20114 |
-+performed, the theme field should point to a char buffer of length |
20115 |
-+FBCON_DECOR_THEME_LEN. |
20116 |
-+ |
20117 |
-+Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h. |
20118 |
-+The fields in this struct have the following meaning: |
20119 |
-+ |
20120 |
-+vc: |
20121 |
-+Virtual console number. |
20122 |
-+ |
20123 |
-+origin: |
20124 |
-+Specifies if the ioctl is performed as a response to a kernel request. The |
20125 |
-+fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace |
20126 |
-+programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to |
20127 |
-+avoid console semaphore deadlocks. |
20128 |
-+ |
20129 |
-+data: |
20130 |
-+Pointer to a data structure appropriate for the performed ioctl. Type of |
20131 |
-+the data struct is specified in the ioctls description. |

-Subject: [PATCH 2/3] block: introduce the BFQ-v7r7 I/O sched for 4.0 |
22495 |
- |
22496 |
-Add the BFQ-v7r7 I/O scheduler to 4.0. |
22497 |
-The general structure is borrowed from CFQ, as much of the code for |
22498 |
-handling I/O contexts. Over time, several useful features have been |
22499 |
-ported from CFQ as well (details in the changelog in README.BFQ). A |
22500 |
-(bfq_)queue is associated to each task doing I/O on a device, and each |
22501 |
-time a scheduling decision has to be made a queue is selected and served |
22502 |
-until it expires. |
22503 |
- |
22504 |
- - Slices are given in the service domain: tasks are assigned |
22505 |
- budgets, measured in number of sectors. Once got the disk, a task |
22506 |
- must however consume its assigned budget within a configurable |
22507 |
- maximum time (by default, the maximum possible value of the |
22508 |
- budgets is automatically computed to comply with this timeout). |
22509 |
- This allows the desired latency vs "throughput boosting" tradeoff |
22510 |
- to be set. |
22511 |
- |
22512 |
- - Budgets are scheduled according to a variant of WF2Q+, implemented |
22513 |
- using an augmented rb-tree to take eligibility into account while |
22514 |
- preserving an O(log N) overall complexity. |
22515 |
- |
22516 |
- - A low-latency tunable is provided; if enabled, both interactive |
22517 |
- and soft real-time applications are guaranteed a very low latency. |
22518 |
- |
22519 |
- - Latency guarantees are preserved also in the presence of NCQ. |
22520 |
- |
22521 |
- - Also with flash-based devices, a high throughput is achieved |
22522 |
- while still preserving latency guarantees. |
22523 |
- |
22524 |
- - BFQ features Early Queue Merge (EQM), a sort of fusion of the |
22525 |
- cooperating-queue-merging and the preemption mechanisms present |
22526 |
- in CFQ. EQM is in fact a unified mechanism that tries to get a |
22527 |
- sequential read pattern, and hence a high throughput, with any |
22528 |
- set of processes performing interleaved I/O over a contiguous |
22529 |
- sequence of sectors. |
22530 |
- |
22531 |
- - BFQ supports full hierarchical scheduling, exporting a cgroups |
22532 |
- interface. Since each node has a full scheduler, each group can |
22533 |
- be assigned its own weight. |
22534 |
- |
22535 |
- - If the cgroups interface is not used, only I/O priorities can be |
22536 |
- assigned to processes, with ioprio values mapped to weights |
22537 |
- with the relation weight = IOPRIO_BE_NR - ioprio. |
22538 |
- |
22539 |
- - ioprio classes are served in strict priority order, i.e., lower |
22540 |
- priority queues are not served as long as there are higher |
22541 |
- priority queues. Among queues in the same class the bandwidth is |
22542 |
- distributed in proportion to the weight of each queue. A very |
22543 |
- thin extra bandwidth is however guaranteed to the Idle class, to |
22544 |
- prevent it from starving. |

23564 |
-+ * |
23565 |
-+ * BFQ is a proportional-share storage-I/O scheduling algorithm based on |
23566 |
-+ * the slice-by-slice service scheme of CFQ. But BFQ assigns budgets, |
23567 |
-+ * measured in number of sectors, to processes instead of time slices. The |
23568 |
-+ * device is not granted to the in-service process for a given time slice, |
23569 |
-+ * but until it has exhausted its assigned budget. This change from the time |
23570 |
-+ * to the service domain allows BFQ to distribute the device throughput |
23571 |
-+ * among processes as desired, without any distortion due to ZBR, workload |
23572 |
-+ * fluctuations or other factors. BFQ uses an ad hoc internal scheduler, |
23573 |
-+ * called B-WF2Q+, to schedule processes according to their budgets. More |
23574 |
-+ * precisely, BFQ schedules queues associated to processes. Thanks to the |
23575 |
-+ * accurate policy of B-WF2Q+, BFQ can afford to assign high budgets to |
23576 |
-+ * I/O-bound processes issuing sequential requests (to boost the |
23577 |
-+ * throughput), and yet guarantee a low latency to interactive and soft |
23578 |
-+ * real-time applications. |
23579 |
-+ * |
23580 |
-+ * BFQ is described in [1], where also a reference to the initial, more |
23581 |
-+ * theoretical paper on BFQ can be found. The interested reader can find |
23582 |
-+ * in the latter paper full details on the main algorithm, as well as |
23583 |
-+ * formulas of the guarantees and formal proofs of all the properties. |
23584 |
-+ * With respect to the version of BFQ presented in these papers, this |
23585 |
-+ * implementation adds a few more heuristics, such as the one that |
23586 |
-+ * guarantees a low latency to soft real-time applications, and a |
23587 |
-+ * hierarchical extension based on H-WF2Q+. |
23588 |
-+ * |
23589 |
-+ * B-WF2Q+ is based on WF2Q+, that is described in [2], together with |
23590 |
-+ * H-WF2Q+, while the augmented tree used to implement B-WF2Q+ with O(log N) |
23591 |
-+ * complexity derives from the one introduced with EEVDF in [3]. |

23674 |
-+ * duration = (R / r) * T, where r is the peak rate of the device, and |
23675 |
-+ * R and T are two reference parameters. |
23676 |

23677 |
-+ * and T is a reference time: given the systems that are likely to be |
23678 |
-+ * installed on the reference device according to its speed class, T is |
23679 |
-+ * about the maximum time needed, under BFQ and while reading two files in |
23680 |
-+ * parallel, to load typical large applications on these systems. |
23681 |
-+ * In practice, the slower/faster the device at hand is, the more/less it |
23682 |
-+ * takes to load applications with respect to the reference device. |
23683 |

23684 |
-+ * applications. |
23685 |
-+ * |
23686 |

23688 |
-+ * . whether the device is slow, such as old or portable HDDs, as well as |

-+ * R_slow[1]/R_fast[1] and T_slow[1]/T_fast[1] are the reference values for |

-+ * If many queues happen to become active shortly after each other, then, |
24178 |
-+ * to help the processes associated to these queues get their job done as |
24179 |
-+ * soon as possible, it is usually better to not grant either weight-raising |
24180 |
-+ * or device idling to these queues. In this comment we describe, firstly, |
24181 |
-+ * the reasons why this fact holds, and, secondly, the next function, which |
24182 |
-+ * implements the main steps needed to properly mark these queues so that |
24183 |
-+ * they can then be treated in a different way. |
24184 |
-+ * |
24185 |
-+ * As for the terminology, we say that a queue becomes active, i.e., |
24186 |
-+ * switches from idle to backlogged, either when it is created (as a |
24187 |
-+ * consequence of the arrival of an I/O request), or, if already existing, |
24188 |
-+ * when a new request for the queue arrives while the queue is idle. |
24189 |
-+ * Bursts of activations, i.e., activations of different queues occurring |
24190 |
-+ * shortly after each other, are typically caused by services or applications |
24191 |
-+ * that spawn or reactivate many parallel threads/processes. Examples are |
24192 |
-+ * systemd during boot or git grep. |
24193 |
-+ * |
24194 |
-+ * These services or applications benefit mostly from a high throughput: |
24195 |
-+ * the quicker the requests of the activated queues are cumulatively served, |
24196 |
-+ * the sooner the target job of these queues gets completed. As a consequence, |
24197 |
-+ * weight-raising any of these queues, which also implies idling the device |
24198 |
-+ * for it, is almost always counterproductive: in most cases it just lowers |
24199 |
-+ * throughput. |
24200 |
-+ * |
24201 |
-+ * On the other hand, a burst of activations may be also caused by the start |
24202 |
-+ * of an application that does not consist in a lot of parallel I/O-bound |
24203 |
-+ * threads. In fact, with a complex application, the burst may be just a |
24204 |
-+ * consequence of the fact that several processes need to be executed to |
24205 |
-+ * start-up the application. To start an application as quickly as possible, |
24206 |
-+ * the best thing to do is to privilege the I/O related to the application |
24207 |
-+ * with respect to all other I/O. Therefore, the best strategy to start as |
24208 |
-+ * quickly as possible an application that causes a burst of activations is |
24209 |
-+ * to weight-raise all the queues activated during the burst. This is the |
24210 |
-+ * exact opposite of the best strategy for the other type of bursts. |
24211 |
-+ * |
24212 |
-+ * In the end, to take the best action for each of the two cases, the two |
24213 |
-+ * types of bursts need to be distinguished. Fortunately, this seems |
24214 |
-+ * relatively easy to do, by looking at the sizes of the bursts. In |
24215 |
-+ * particular, we found a threshold such that bursts with a larger size |
24216 |
-+ * than that threshold are apparently caused only by services or commands |
24217 |
-+ * such as systemd or git grep. For brevity, hereafter we call just 'large' |
24218 |
-+ * these bursts. BFQ *does not* weight-raise queues whose activations occur |
24219 |
-+ * in a large burst. In addition, for each of these queues BFQ performs or |
24220 |
-+ * does not perform idling depending on which choice boosts the throughput |
24221 |
-+ * most. The exact choice depends on the device and request pattern at |
24222 |
-+ * hand. |
24223 |
-+ * |
24224 |
-+ * Turning back to the next function, it implements all the steps needed |
24225 |
-+ * to detect the occurrence of a large burst and to properly mark all the |
24226 |
-+ * queues belonging to it (so that they can then be treated in a different |
24227 |
-+ * way). This goal is achieved by maintaining a special "burst list" that |
24228 |
-+ * holds, temporarily, the queues that belong to the burst in progress. The |
24229 |
-+ * list is then used to mark these queues as belonging to a large burst if |
24230 |
-+ * the burst does become large. The main steps are the following. |
24231 |
-+ * |
24232 |
-+ * . when the very first queue is activated, the queue is inserted into the |
24233 |
-+ * list (as it could be the first queue in a possible burst) |
24234 |
-+ * |
24235 |
-+ * . if the current burst has not yet become large, and a queue Q that does |
24236 |
-+ * not yet belong to the burst is activated shortly after the last time |
24237 |
-+ * at which a new queue entered the burst list, then the function appends |
24238 |
-+ * Q to the burst list |
24239 |
-+ * |
24240 |
-+ * . if, as a consequence of the previous step, the burst size reaches |
24241 |
-+ * the large-burst threshold, then |
24242 |
-+ * |
24243 |
-+ * . all the queues in the burst list are marked as belonging to a |
24244 |
-+ * large burst |
24245 |
-+ * |
24246 |
-+ * . the burst list is deleted; in fact, the burst list already served |
24247 |
-+ * its purpose (keeping temporarily track of the queues in a burst, |
24248 |
-+ * so as to be able to mark them as belonging to a large burst in the |
24249 |
-+ * previous sub-step), and now is not needed any more |
24250 |
-+ * |
24251 |
-+ * . the device enters a large-burst mode |
24252 |
-+ * |
24253 |
-+ * . if a queue Q that does not belong to the burst is activated while |
24254 |
-+ * the device is in large-burst mode and shortly after the last time |
24255 |
-+ * at which a queue either entered the burst list or was marked as |
24256 |
-+ * belonging to the current large burst, then Q is immediately marked |
24257 |
-+ * as belonging to a large burst. |
24258 |
-+ * |
24259 |
-+ * . if a queue Q that does not belong to the burst is activated a while |
24260 |
-+ * later, i.e., not shortly after, than the last time at which a queue |
24261 |
-+ * either entered the burst list or was marked as belonging to the |
24262 |
-+ * current large burst, then the current burst is deemed as finished and: |
24263 |
-+ * |
24264 |
-+ * . the large-burst mode is reset if set |
24265 |
-+ * |
24266 |
-+ * . the burst list is emptied |
24267 |
-+ * |
24268 |
-+ * . Q is inserted in the burst list, as Q may be the first queue |
24269 |
-+ * in a possible new burst (then the burst list contains just Q |

25400 |
-+ * The second requirement is that the request pattern of the application is |
25401 |
-+ * isochronous, i.e., that, after issuing a request or a batch of requests, |
25402 |
-+ * the application stops issuing new requests until all its pending requests |
25403 |
-+ * have been completed. After that, the application may issue a new batch, |
25404 |
-+ * and so on. |
25405 |
-+ * For this reason the next function is invoked to compute |
25406 |
-+ * soft_rt_next_start only for applications that meet this requirement, |
25407 |
-+ * whereas soft_rt_next_start is set to infinity for applications that do |
25408 |
-+ * not. |
25409 |
-+ * |
25410 |
-+ * Unfortunately, even a greedy application may happen to behave in an |
25411 |
-+ * isochronous way if the CPU load is high. In fact, the application may |
25412 |
-+ * stop issuing requests while the CPUs are busy serving other processes, |
25413 |
-+ * then restart, then stop again for a while, and so on. In addition, if |
25414 |
-+ * the disk achieves a low enough throughput with the request pattern |
25415 |
-+ * issued by the application (e.g., because the request pattern is random |
25416 |
-+ * and/or the device is slow), then the application may meet the above |
25417 |
-+ * bandwidth requirement too. To prevent such a greedy application to be |
25418 |
-+ * deemed as soft real-time, a further rule is used in the computation of |
25419 |
-+ * soft_rt_next_start: soft_rt_next_start must be higher than the current |
25420 |
-+ * time plus the maximum time for which the arrival of a request is waited |
25421 |
-+ * for when a sync queue becomes idle, namely bfqd->bfq_slice_idle. |
25422 |
-+ * This filters out greedy applications, as the latter issue instead their |
25423 |
-+ * next request as soon as possible after the last one has been completed |
25424 |
-+ * (in contrast, when a batch of requests is completed, a soft real-time |
25425 |
-+ * application spends some time processing data). |
25426 |
-+ * |
25427 |
-+ * Unfortunately, the last filter may easily generate false positives if |
25428 |
-+ * only bfqd->bfq_slice_idle is used as a reference time interval and one |
25429 |
-+ * or both the following cases occur: |
25430 |
-+ * 1) HZ is so low that the duration of a jiffy is comparable to or higher |
25431 |
-+ * than bfqd->bfq_slice_idle. This happens, e.g., on slow devices with |
25432 |
-+ * HZ=100. |
25433 |
-+ * 2) jiffies, instead of increasing at a constant rate, may stop increasing |
25434 |
-+ * for a while, then suddenly 'jump' by several units to recover the lost |
25435 |
-+ * increments. This seems to happen, e.g., inside virtual machines. |
25436 |
-+ * To address this issue, we do not use as a reference time interval just |
25437 |
-+ * bfqd->bfq_slice_idle, but bfqd->bfq_slice_idle plus a few jiffies. In |
25438 |
-+ * particular we add the minimum number of jiffies for which the filter |
25439 |
-+ * seems to be quite precise also in embedded systems and KVM/QEMU virtual |
25440 |

-+ * returns true. For this reason, the return value of this function plays a |
25626 |
-+ * critical role for both throughput boosting and service guarantees. The |
25627 |
-+ * return value is computed through a logical expression. In this rather |
25628 |
-+ * long comment, we try to briefly describe all the details and motivations |
25629 |
-+ * behind the components of this logical expression. |
25630 |
-+ * |
25631 |
-+ * First, the expression is false if bfqq is not sync, or if: bfqq happened |
25632 |
-+ * to become active during a large burst of queue activations, and the |
25633 |
-+ * pattern of requests bfqq contains boosts the throughput if bfqq is |
25634 |
-+ * expired. In fact, queues that became active during a large burst benefit |
25635 |
-+ * only from throughput, as discussed in the comments to bfq_handle_burst. |
25636 |
-+ * In this respect, expiring bfqq certainly boosts the throughput on NCQ- |
25637 |
-+ * capable flash-based devices, whereas, on rotational devices, it boosts |
25638 |
-+ * the throughput only if bfqq contains random requests. |
25639 |
-+ * |
25640 |
-+ * On the opposite end, if (a) bfqq is sync, (b) the above burst-related |
25641 |
-+ * condition does not hold, and (c) bfqq is being weight-raised, then the |
25642 |
-+ * expression always evaluates to true, as device idling is instrumental |
25643 |
-+ * for preserving low-latency guarantees (see [1]). If, instead, conditions |
25644 |
-+ * (a) and (b) do hold, but (c) does not, then the expression evaluates to |
25645 |
-+ * true only if: (1) bfqq is I/O-bound and has a non-null idle window, and |
25646 |
-+ * (2) at least one of the following two conditions holds. |
25647 |
-+ * The first condition is that the device is not performing NCQ, because |
25648 |
-+ * idling the device most certainly boosts the throughput if this condition |
25649 |
-+ * holds and bfqq is I/O-bound and has been granted a non-null idle window. |
25650 |
-+ * The second compound condition is made of the logical AND of two components. |
25651 |
-+ * |
25652 |
-+ * The first component is true only if there is no weight-raised busy |
25653 |
-+ * queue. This guarantees that the device is not idled for a sync non- |
25654 |
-+ * weight-raised queue when there are busy weight-raised queues. The former |
25655 |
-+ * is then expired immediately if empty. Combined with the timestamping |
25656 |
-+ * rules of BFQ (see [1] for details), this causes sync non-weight-raised |
25657 |
-+ * queues to get a lower number of requests served, and hence to ask for a |
25658 |
-+ * lower number of requests from the request pool, before the busy weight- |
25659 |
-+ * raised queues get served again. |
25660 |
-+ * |
25661 |
-+ * This is beneficial for the processes associated with weight-raised |
25662 |
-+ * queues, when the request pool is saturated (e.g., in the presence of |
25663 |
-+ * write hogs). In fact, if the processes associated with the other queues |
25664 |
-+ * ask for requests at a lower rate, then weight-raised processes have a |
25665 |
-+ * higher probability to get a request from the pool immediately (or at |
25666 |
-+ * least soon) when they need one. Hence they have a higher probability to |
25667 |
-+ * actually get a fraction of the disk throughput proportional to their |
25668 |
-+ * high weight. This is especially true with NCQ-capable drives, which |
25669 |
-+ * enqueue several requests in advance and further reorder internally- |
25670 |
-+ * queued requests. |
25671 |
-+ * |
25672 |
-+ * In the end, mistreating non-weight-raised queues when there are busy |
25673 |
-+ * weight-raised queues seems to mitigate starvation problems in the |
25674 |
-+ * presence of heavy write workloads and NCQ, and hence to guarantee a |
25675 |
-+ * higher application and system responsiveness in these hostile scenarios. |
25676 |
-+ * |
25677 |
-+ * If the first component of the compound condition is instead true, i.e., |
25678 |
-+ * there is no weight-raised busy queue, then the second component of the |
25679 |
-+ * compound condition takes into account service-guarantee and throughput |
25680 |
-+ * issues related to NCQ (recall that the compound condition is evaluated |
25681 |
-+ * only if the device is detected as supporting NCQ). |
25682 |
-+ * |
25683 |
-+ * As for service guarantees, allowing the drive to enqueue more than one |
25684 |
-+ * request at a time, and hence delegating de facto final scheduling |
25685 |
-+ * decisions to the drive's internal scheduler, causes loss of control on |
25686 |
-+ * the actual request service order. In this respect, when the drive is |
25687 |
-+ * allowed to enqueue more than one request at a time, the service |
25688 |
-+ * distribution enforced by the drive's internal scheduler is likely to |
25689 |
-+ * coincide with the desired device-throughput distribution only in the |
25690 |
-+ * following, perfectly symmetric, scenario: |
25691 |
-+ * 1) all active queues have the same weight, |
25692 |
-+ * 2) all active groups at the same level in the groups tree have the same |
25693 |
-+ * weight, |
25694 |
-+ * 3) all active groups at the same level in the groups tree have the same |
25695 |
-+ * number of children. |
25696 |
-+ * |
25697 |
-+ * Even in such a scenario, sequential I/O may still receive a preferential |
25698 |
-+ * treatment, but this is not likely to be a big issue with flash-based |
25699 |
-+ * devices, because of their non-dramatic loss of throughput with random |
25700 |
-+ * I/O. Things do differ with HDDs, for which additional care is taken, as |
25701 |
-+ * explained after completing the discussion for flash-based devices. |
25702 |
-+ * |
25703 |
-+ * Unfortunately, keeping the necessary state for evaluating exactly the |
25704 |
-+ * above symmetry conditions would be quite complex and time-consuming. |
25705 |
-+ * Therefore BFQ evaluates instead the following stronger sub-conditions, |
25706 |
-+ * for which it is much easier to maintain the needed state: |
25707 |
-+ * 1) all active queues have the same weight, |
25708 |
-+ * 2) all active groups have the same weight, |
25709 |
-+ * 3) all active groups have at most one active child each. |
25710 |
-+ * In particular, the last two conditions are always true if hierarchical |
25711 |
-+ * support and the cgroups interface are not enabled, hence no state needs |
25712 |
-+ * to be maintained in this case. |
25713 |
-+ * |
25714 |
-+ * According to the above considerations, the second component of the |
25715 |
-+ * compound condition evaluates to true if any of the above symmetry |
25716 |
-+ * sub-condition does not hold, or the device is not flash-based. Therefore, |
25717 |
-+ * if also the first component is true, then idling is allowed for a sync |
25718 |
-+ * queue. These are the only sub-conditions considered if the device is |
25719 |
-+ * flash-based, as, for such a device, it is sensible to force idling only |
25720 |
-+ * for service-guarantee issues. In fact, as for throughput, idling |
25721 |
-+ * NCQ-capable flash-based devices would not boost the throughput even |
25722 |
-+ * with sequential I/O; rather it would lower the throughput in proportion |
25723 |
-+ * to how fast the device is. In the end, (only) if all the three |
25724 |
-+ * sub-conditions hold and the device is flash-based, the compound |
25725 |
-+ * condition evaluates to false and therefore no idling is performed. |
25726 |
-+ * |
25727 |
-+ * As already said, things change with a rotational device, where idling |
25728 |
-+ * boosts the throughput with sequential I/O (even with NCQ). Hence, for |
25729 |
-+ * such a device the second component of the compound condition evaluates |
25730 |
-+ * to true also if the following additional sub-condition does not hold: |
25731 |
-+ * the queue is constantly seeky. Unfortunately, this different behavior |
25732 |
-+ * with respect to flash-based devices causes an additional asymmetry: if |
25733 |
-+ * some sync queues enjoy idling and some other sync queues do not, then |
25734 |
-+ * the latter get a low share of the device throughput, simply because the |
25735 |
-+ * former get many requests served after being set as in service, whereas |
25736 |
-+ * the latter do not. As a consequence, to guarantee the desired throughput |
25737 |
-+ * distribution, on HDDs the compound expression evaluates to true (and |
25738 |
-+ * hence device idling is performed) also if the following last symmetry |
25739 |
-+ * condition does not hold: no other queue is benefiting from idling. Also |
25740 |
-+ * this last condition is actually replaced with a simpler-to-maintain and |
25741 |
-+ * stronger condition: there is no busy queue which is not constantly seeky |
25742 |
-+ * (and hence may also benefit from idling). |
25743 |
-+ * |
25744 |
-+ * To sum up, when all the required symmetry and throughput-boosting |
25745 |
-+ * sub-conditions hold, the second component of the compound condition |
25746 |
-+ * evaluates to false, and hence no idling is performed. This helps to |
25747 |
-+ * keep the drives' internal queues full on NCQ-capable devices, and hence |
25748 |
-+ * to boost the throughput, without causing 'almost' any loss of service |
25749 |
-+ * guarantees. The 'almost' follows from the fact that, if the internal |
25750 |
-+ * queue of one such device is filled while all the sub-conditions hold, |
25751 |
-+ * but at some point in time some sub-condition stops to hold, then it may |
25752 |
-+ * become impossible to let requests be served in the new desired order |
25753 |
-+ * until all the requests already queued in the device have been served. |

28999 |

29000 |
-+ * active @bfq_entity. |
29001 |
-+ * @queue_weights_tree: rbtree of weight counters of @bfq_queues, sorted by |
29002 |
-+ * weight. Used to keep track of whether all @bfq_queues |
29003 |

29008 |

29023 |
-+ * The reason why the field is updated also for non- |
29024 |
-+ * NCQ-capable rotational devices is related to the |
29025 |

29026 |

29027 |

29028 |
-+ * this possibility into account, to avoid unbalanced |
29029 |
-+ * increments/decrements, would imply more overhead |
29030 |
-+ * than just updating busy_in_flight_queues |
29031 |
-+ * regardless of the value of @hw_tag. |
29032 |
-+ * @const_seeky_busy_in_flight_queues: number of constantly-seeky @bfq_queues |

29037 |
-+ * @bfq_queue if constantly seeky. This |
29038 |
-+ * field is updated only if the device |
29039 |
-+ * is rotational, but used only if the |
29040 |

29042 |

29074 |
-+ * @bfq_max_budget_async_rq: maximum budget (in nr of requests) allotted to |
29075 |
-+ * async queues. |
29076 |
-+ * @bfq_timeout: timeout for bfq_queues to consume their budget; used to |
29077 |
-+ * to prevent seeky queues to impose long latencies to well |
29078 |
-+ * behaved ones (this also implies that seeky queues cannot |
29079 |
-+ * receive guarantees in the service domain; after a timeout |
29080 |
-+ * they are charged for the whole allocated budget, to try |
29081 |

29096 |
-+ * each other; for more details about this and the |

29098 |
-+ * activations, see the comments to the function |
29099 |
-+ * @bfq_handle_burst. |
29100 |
-+ * @bfq_burst_interval: reference time interval used to decide whether a |
29101 |
-+ * queue has been activated shortly after |

29111 |
-+ * queue is multiplied. |
29112 |
-+ * @bfq_wr_max_time: maximum duration of a weight-raising period (jiffies). |
29113 |
-+ * @bfq_wr_rt_max_time: maximum duration for soft real-time processes. |
29114 |
-+ * @bfq_wr_min_idle_time: minimum idle period after which weight-raising |
29115 |

-Subject: [PATCH 3/3] block, bfq: add Early Queue Merge (EQM) to BFQ-v7r7 for |
29468 |
- 4.0.0 |
29469 |
- |
29470 |
-A set of processes may happen to perform interleaved reads, i.e.,requests |
29471 |
-whose union would give rise to a sequential read pattern. There are two |
29472 |
-typical cases: in the first case, processes read fixed-size chunks of |
29473 |
-data at a fixed distance from each other, while in the second case processes |
29474 |
-may read variable-size chunks at variable distances. The latter case occurs |
29475 |
-for example with QEMU, which splits the I/O generated by the guest into |
29476 |
-multiple chunks, and lets these chunks be served by a pool of cooperating |
29477 |
-processes, iteratively assigning the next chunk of I/O to the first |
29478 |
-available process. CFQ uses actual queue merging for the first type of |
29479 |
-rocesses, whereas it uses preemption to get a sequential read pattern out |
29480 |
-of the read requests performed by the second type of processes. In the end |
29481 |
-it uses two different mechanisms to achieve the same goal: boosting the |
29482 |
-throughput with interleaved I/O. |
29483 |
- |
29484 |
-This patch introduces Early Queue Merge (EQM), a unified mechanism to get a |
29485 |
-sequential read pattern with both types of processes. The main idea is |
29486 |
-checking newly arrived requests against the next request of the active queue |
29487 |
-both in case of actual request insert and in case of request merge. By doing |
29488 |
-so, both the types of processes can be handled by just merging their queues. |
29489 |
-EQM is then simpler and more compact than the pair of mechanisms used in |
29490 |
-CFQ. |
29491 |
- |
29492 |
-Finally, EQM also preserves the typical low-latency properties of BFQ, by |
29493 |
-properly restoring the weight-raising state of a queue when it gets back to |
29494 |
-a non-merged state. |

-WARNING - this version of the patch works with version 4.9+ of gcc and with |
30694 |
-kernel version 3.15.x+ and should NOT be applied when compiling on older |
30695 |
-versions due to name changes of the flags with the 4.9 release of gcc. |
30696 |
-Use the older version of this patch hosted on the same github for older |
30697 |

-It also changes 'atom' to 'bonnell' in accordance with the gcc v4.9 changes. |
30707 |
-Note that upstream is using the deprecated 'match=atom' flags when I believe it |
30708 |
-should use the newer 'march=bonnell' flag for atom processors. |
