Pavankumar Kondeti	5b3db45955	sched/walt: Move scheduler techpack to kernel ... The scheduler techpack sources are moved to kernel to ease the development. The weak symbol definitions for WALT functions are no longer required to cover the case of compiling kernel without syncing the scheduler techpack. So remove all the weak symbol references. Change-Id: Ief85bccd3dceaf60dda44aef9893b4138dc63380 Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org>	2021-01-28 17:23:24 +05:30
Jeevan Shriram	7bd4f1b732	sched: use wake_q length only when WALT is enabled ... Upstream commit aa8b37baac ("FROMLIST: sched/fair: Use wake_q length as a hint for wake_wide") that is being carried in msm-5.4 kernel caused CRC checks failures when GKI boot image is used for verification as the commit adds extra argument to select_task_rq(). Fix this issue by wrapping extra argument under CONFIG_SCHED_WALT.

Pavankumar Kondeti	260fab38d8	sched/walt: Remove fixup_walt_sched_stats sched_class method ... fixup_walt_sched_stats method in sched_class was required because fair class need to handle it differently when CFS_BANDWIDTH feature is enabled. Since that is gone, we can remove this method and reduce WALT footprint in other files.

Brendan Jackman	aa8b37baac	FROMLIST: sched/fair: Use wake_q length as a hint for wake_wide ... This patch adds a parameter to select_task_rq, sibling_count_hint allowing the caller, where it has this information, to inform the sched_class the number of tasks that are being woken up as part of the same event. The wake_q mechanism is one case where this information is available. select_task_rq_fair can then use the information to detect that it needs to widen the search space for task placement in order to avoid overloading the last-level cache domain's CPUs. * * * The reason I am investigating this change is the following use case on ARM big.LITTLE (asymmetrical CPU capacity): 1 task per CPU, which all repeatedly do X amount of work then pthread_barrier_wait (i.e. sleep until the last task finishes its X and hits the barrier). On big.LITTLE, the tasks which get a "big" CPU finish faster, and then those CPUs pull over the tasks that are still running: v CPU v ->time-> ------------- 0 (big) 11111 /333 ------------- 1 (big) 22222 /444| ------------- 2 (LITTLE) 333333/ ------------- 3 (LITTLE) 444444/ ------------- Now when task 4 hits the barrier (at |) and wakes the others up, there are 4 tasks with prev_cpu=<big> and 0 tasks with prev_cpu=<little>. want_affine therefore means that we'll only look in CPUs 0 and 1 (sd_llc), so tasks will be unnecessarily coscheduled on the bigs until the next load balance, something like this: v CPU v ->time-> ------------------------ 0 (big) 11111 /333 31313\33333 ------------------------ 1 (big) 22222 /444|424\4444444 ------------------------ 2 (LITTLE) 333333/ \222222 ------------------------ 3 (LITTLE) 444444/ \1111 ------------------------ ^^^ underutilization So, I'm trying to get want_affine = 0 for these tasks. I don't _think_ any incarnation of the wakee_flips mechanism can help us here because which task is waker and which tasks are wakees generally changes with each iteration. However pthread_barrier_wait (or more accurately FUTEX_WAKE) has the nice property that we know exactly how many tasks are being woken, so we can cheat. It might be a disadvantage that we "widen" _every_ task that's woken in an event, while select_idle_sibling would work fine for the first sd_llc_size - 1 tasks. IIUC, if wake_affine() behaves correctly this trick wouldn't be necessary on SMP systems, so it might be best guarded by the presence of SD_ASYM_CPUCAPACITY? * * * Final note.. In order to observe "perfect" behaviour for this use case, I also had to disable the TTWU_QUEUE sched feature. Suppose during the wakeup above we are working through the work queue and have placed tasks 3 and 2, and are about to place task 1: v CPU v ->time-> -------------- 0 (big) 11111 /333 3 -------------- 1 (big) 22222 /444|4 -------------- 2 (LITTLE) 333333/ 2 -------------- 3 (LITTLE) 444444/ <- Task 1 should go here -------------- If TTWU_QUEUE is enabled, we will not yet have enqueued task 2 (having instead sent a reschedule IPI) or attached its load to CPU 2. So we are likely to also place task 1 on cpu 2. Disabling TTWU_QUEUE means that we enqueue task 2 before placing task 1, solving this issue. TTWU_QUEUE is there to minimise rq lock contention, and I guess that this contention is less of an issue on big.LITTLE systems since they have relatively few CPUs, which suggests the trade-off makes sense here.

Peter Zijlstra	6e2df0581f	sched: Fix pick_next_task() vs 'change' pattern race ... Commit 67692435c4 ("sched: Rework pick_next_task() slow-path") inadvertly introduced a race because it changed a previously unexplored dependency between dropping the rq->lock and sched_class::put_prev_task(). The comments about dropping rq->lock, in for example newidle_balance(), only mentions the task being current and ->on_cpu being set. But when we look at the 'change' pattern (in for example sched_setnuma()): queued = task_on_rq_queued(p); /* p->on_rq == TASK_ON_RQ_QUEUED */ running = task_current(rq, p); /* rq->curr == p */ if (queued) dequeue_task(...); if (running) put_prev_task(...); /* change task properties */ if (queued) enqueue_task(...); if (running) set_next_task(...); It becomes obvious that if we do this after put_prev_task() has already been called on @p, things go sideways. This is exactly what the commit in question allows to happen when it does: prev->sched_class->put_prev_task(rq, prev, rf); if (!rq->nr_running) newidle_balance(rq, rf); The newidle_balance() call will drop rq->lock after we've called put_prev_task() and that allows the above 'change' pattern to interleave and mess up the state. Furthermore, it turns out we lost the RT-pull when we put the last DL task. Fix both problems by extracting the balancing from put_prev_task() and doing a multi-class balance() pass before put_prev_task().

Frederic Weisbecker	d84b31313e	sched/isolation: Offload residual 1Hz scheduler tick ... When a CPU runs in full dynticks mode, a 1Hz tick remains in order to keep the scheduler stats alive. However this residual tick is a burden for bare metal tasks that can't stand any interruption at all, or want to minimize them. The usual boot parameters "nohz_full=" or "isolcpus=nohz" will now outsource these scheduler ticks to the global workqueue so that a housekeeping CPU handles those remotely. The sched_class::task_tick() implementations have been audited and look safe to be called remotely as the target runqueue and its current task are passed in parameter and don't seem to be accessed locally. Note that in the case of using isolcpus, it's still up to the user to affine the global workqueues to the housekeeping CPUs through /sys/devices/virtual/workqueue/cpumask or domains isolation "isolcpus=nohz,domain".

Greg Kroah-Hartman	b24413180f	License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

Thomas Gleixner	90e362f4a7	sched: Provide update_curr callbacks for stop/idle scheduling classes ... Chris bisected a NULL pointer deference in task_sched_runtime() to commit 6e998916df 'sched/cputime: Fix clock_nanosleep()/clock_gettime() inconsistency'. Chris observed crashes in atop or other /proc walking programs when he started fork bombs on his machine. He assumed that this is a new exit race, but that does not make any sense when looking at that commit. What's interesting is that, the commit provides update_curr callbacks for all scheduling classes except stop_task and idle_task. While nothing can ever hit that via the clock_nanosleep() and clock_gettime() interfaces, which have been the target of the commit in question, the author obviously forgot that there are other code paths which invoke task_sched_runtime() do_task_stat(() thread_group_cputime_adjusted() thread_group_cputime() task_cputime() task_sched_runtime() if (task_current(rq, p) && task_on_rq_queued(p)) { update_rq_clock(rq); up->sched_class->update_curr(rq); } If the stats are read for a stomp machine task, aka 'migration/N' and that task is current on its cpu, this will happily call the NULL pointer of stop_task->update_curr. Ooops. Chris observation that this happens faster when he runs the fork bomb makes sense as the fork bomb will kick migration threads more often so the probability to hit the issue will increase. Add the missing update_curr callbacks to the scheduler classes stop_task and idle_task. While idle tasks cannot be monitored via /proc we have other means to hit the idle case.

Peter Zijlstra	3f1d2a3181	sched: Fix hotplug task migration ... Dan Carpenter reported: > kernel/sched/rt.c:1347 pick_next_task_rt() warn: variable dereferenced before check 'prev' (see line 1338) > kernel/sched/deadline.c:1011 pick_next_task_dl() warn: variable dereferenced before check 'prev' (see line 1005) Kirill also spotted that migrate_tasks() will have an instant NULL deref because pick_next_task() will immediately deref prev. Instead of fixing all the corner cases because migrate_tasks() can pass in a NULL prev task in the unlikely case of hot-un-plug, provide a fake task such that we can remove all the NULL checks from the far more common paths. A further problem; not previously spotted; is that because we pushed pre_schedule() and idle_balance() into pick_next_task() we now need to avoid those getting called and pulling more tasks on our dying CPU. We avoid pull_{dl,rt}_task() by setting fake_task.prio to MAX_PRIO+1. We also note that since we call pick_next_task() exactly the amount of times we have runnable tasks present, we should never land in idle_balance().

Dario Faggioli	aab03e05e8	sched/deadline: Add SCHED_DEADLINE structures & implementation ... Introduces the data structures, constants and symbols needed for SCHED_DEADLINE implementation. Core data structure of SCHED_DEADLINE are defined, along with their initializers. Hooks for checking if a task belong to the new policy are also added where they are needed. Adds a scheduling class, in sched/dl.c and a new policy called SCHED_DEADLINE. It is an implementation of the Earliest Deadline First (EDF) scheduling algorithm, augmented with a mechanism (called Constant Bandwidth Server, CBS) that makes it possible to isolate the behaviour of tasks between each other. The typical -deadline task will be made up of a computation phase (instance) which is activated on a periodic or sporadic fashion. The expected (maximum) duration of such computation is called the task's runtime; the time interval by which each instance need to be completed is called the task's relative deadline. The task's absolute deadline is dynamically calculated as the time instant a task (better, an instance) activates plus the relative deadline. The EDF algorithms selects the task with the smallest absolute deadline as the one to be executed first, while the CBS ensures each task to run for at most its runtime every (relative) deadline length time interval, avoiding any interference between different tasks (bandwidth isolation). Thanks to this feature, also tasks that do not strictly comply with the computational model sketched above can effectively use the new policy. To summarize, this patch: - introduces the data structures, constants and symbols needed; - implements the core logic of the scheduling algorithm in the new scheduling class file; - provides all the glue code between the new scheduling class and the core scheduler and refines the interactions between sched/dl and the other existing scheduling classes.

Peter Zijlstra	ac66f54772	sched/numa: Introduce migrate_swap() ... Use the new stop_two_cpus() to implement migrate_swap(), a function that flips two tasks between their respective cpus. I'm fairly sure there's a less crude way than employing the stop_two_cpus() method, but everything I tried either got horribly fragile and/or complex. So keep it simple for now. The notable detail is how we 'migrate' tasks that aren't runnable anymore. We'll make it appear like we migrated them before they went to sleep. The sole difference is the previous cpu in the wakeup path, so we override this.
