2a52ca7c - sched_ext: Add scx_simple and scx_example_qmap example schedulers

Tue, 18 Jun 2024 20:09:17 +0000

sched_ext: Add scx_simple and scx_example_qmap example schedulersAdd two simple example BPF schedulers - simple and qmap.* simple: In terms of scheduling, it behaves identical to not having any operation implemented at all. The two operations it implements are only to improve visibility and exit handling. On certain homogeneous configurations, this actually can perform pretty well.* qmap: A fixed five level priority scheduler to demonstrate queueing PIDs on BPF maps for scheduling. While not very practical, this is useful as a simple example and will be used to demonstrate different features.v7: - Compat helpers stripped out in prepartion of upstreaming as the upstreamed patchset will be the baselinfe. Utility macros that can be used to implement compat features are kept. - Explicitly disable map autoattach on struct_ops to avoid trying to attach twice while maintaining compatbility with older libbpf.v6: - Common header files reorganized and cleaned up. Compat helpers are added to demonstrate how schedulers can maintain backward compatibility with older kernels while making use of newly added features. - simple_select_cpu() added to keep track of the number of local dispatches. This is needed because the default ops.select_cpu() implementation is updated to dispatch directly and won't call ops.enqueue(). - Updated to reflect the sched_ext API changes. Switching all tasks is the default behavior now and scx_qmap supports partial switching when `-p` is specified. - tools/sched_ext/Kconfig dropped. This will be included in the doc instead.v5: - Improve Makefile. Build artifects are now collected into a separate dir which change be changed. Install and help targets are added and clean actually cleans everything. - MEMBER_VPTR() improved to improve access to structs. ARRAY_ELEM_PTR() and RESIZEABLE_ARRAY() are added to support resizable arrays in .bss. - Add scx_common.h which provides common utilities to user code such as SCX_BUG[_ON]() and RESIZE_ARRAY(). - Use SCX_BUG[_ON]() to simplify error handling.v4: - Dropped _example prefix from scheduler names.v3: - Rename scx_example_dummy to scx_example_simple and restructure a bit to ease later additions. Comment updates. - Added declarations for BPF inline iterators. In the future, hopefully, these will be consolidated into a generic BPF header so that they don't need to be replicated here.v2: - Updated with the generic BPF cpumask helpers.Signed-off-by: Tejun Heo Reviewed-by: David Vernet Acked-by: Josh Don Acked-by: Hao Luo Acked-by: Barret Rhoden List of files: /linux-6.15/tools/Makefile

tools/thermal: Add thermal daemon skeletonThis change provides a simple daemon skeleton. It is an example of howto use the thermal library which wraps all the complex code related tothe netlink and transforms it into a callback oriented code.The goal of this skeleton is to give a base brick for anyoneinterested in writing its own thermal engine or as an example to relyon to write its own thermal monitoring implementation.In the future, it will evolve with more features and hopefully morelogic.Signed-off-by: Daniel Lezcano Tested-by: Srinivas Pandruvada Link: https://lore.kernel.org/r/20220420160933.347088-5-daniel.lezcano@linaro.org List of files: /linux-6.15/tools/Makefile

7246f4dc - tools/lib/lockdep: drop liblockdep

Fri, 12 Nov 2021 15:16:02 +0000

tools/lib/lockdep: drop liblockdepTL;DR: While a tool like liblockdep is useful, it probably doesn'tbelong within the kernel tree.liblockdep attempts to reuse kernel code both directly (by directlybuilding the kernel's lockdep code) as well as indirectly (by usingsanitized headers). This makes liblockdep an integral part of thekernel.It also makes liblockdep quite unique: while other userspace code mightuse sanitized headers, it generally doesn't attempt to use kernel codedirectly which means that changes on the kernel side of things don'taffect (and break) it directly.All our workflows and tooling around liblockdep don't support thisuniqueness. Changes that go into the kernel code aren't validated to notbreak in-tree userspace code.liblockdep ended up being very fragile, breaking over and over, to thepoint that living in the same tree as the lockdep code lost most of it'svalue.liblockdep should continue living in an external tree, syncing withthe kernel often, in a controllable way.Signed-off-by: Sasha Levin Cc: Ingo Molnar Cc: Peter Zijlstra Signed-off-by: Linus Torvalds List of files: /linux-6.15/tools/Makefile

e23db805 - tracing/tools: Add the latency-collector to tools directory

Fri, 12 Feb 2021 13:44:21 +0000

tracing/tools: Add the latency-collector to tools directoryThis is a tool that is intended to work around the fact that thepreemptoff, irqsoff, and preemptirqsoff tracers only work inoverwrite mode. The idea is to act randomly in such a way that wedo not systematically lose any latencies, so that if enough testingis done, all latencies will be captured. If the same burst oflatencies is repeated, then sooner or later we will have captured allthe latencies.It also works with the wakeup_dl, wakeup_rt, and wakeup tracers.However, in that case it is probably not useful to use the randomsleep functionality.The reason why it may be desirable to catch all latencies with a longtest campaign is that for some organizations, it's necessary to testthe kernel in the field and not practical for developers to workiteratively with field testers. Because of cost and project schedulesit is not possible to start a new test campaign every time a latencyproblem has been fixed.It uses inotify to detect changes to /sys/kernel/tracing/trace.When a latency is detected, it will either sleep or printimmediately, depending on a function that act as an unfair cointoss.If immediate print is chosen, it means that we open/sys/kernel/tracing/trace and thereby cause a blackout periodthat will hide any subsequent latencies.If sleep is chosen, it means that we wait before opening/sys/kernel/tracing/trace, by default for 1000 ms, to see ifthere is another latency during this period. If there is, then we willlose the previous latency. The coin will be tossed again with adifferent probability, and we will either print the new latency, orpossibly a subsequent one.The probability for the unfair coin toss is chosen so that thereis equal probability to obtain any of the latencies in a burst.However, this assumes that we make an assumption of how manylatencies there can be. By default the program assumes that thereare no more than 2 latencies in a burst, the probability of immediateprintout will be:1/2 and 1Thus, the probability of getting each of the two latencies will be 1/2.If we ever find that there is more than one latency in a series,meaning that we reach the probability of 1, then the table will beexpanded to:1/3, 1/2, and 1Thus, we assume that there are no more than three latencies and eachwith a probability of 1/3 of being captured. If the probability of 1is reached in the new table, that is we see more than two closelyoccurring latencies, then the table will again be extended, and soon.On my systems, it seems like this scheme works fairly well, aslong as the latencies we trace are long enough, 300 us seems to beenough. This userspace program receive the inotify event at the endof a latency, and it has time until the end of the next latencyto react, that is to open /sys/kernel/tracing/trace. Thus,if we trace latencies that are >300 us, then we have at least 300 usto react.The minimum latency will of course not be 300 us on all systems, itwill depend on the hardware, kernel version, workload andconfiguration.Example usage:In one shell, give the following command:sudo latency-collector -rvv -t preemptirqsoff -s 2000 -a 3This will trace latencies > 2000us with the preemptirqsoff tracer,using random sleep with maximum verbosity, with a probabilitytable initialized to a size of 3.In another shell, generate a few bursts of latencies:root@host:~# modprobe preemptirq_delay_test delay=3000 test_mode=alternateburst_size=3root@host:~# echo 1 > /sys/kernel/preemptirq_delay_test/triggerroot@host:~# echo 1 > /sys/kernel/preemptirq_delay_test/triggerroot@host:~# echo 1 > /sys/kernel/preemptirq_delay_test/triggerroot@host:~# echo 1 > /sys/kernel/preemptirq_delay_test/triggerIf all goes well, you should be getting stack traces that showsall the different latencies, i.e. you should see all the threefunctions preemptirqtest_0, preemptirqtest_1, preemptirqtest_2 in thestack traces.Link: https://lkml.kernel.org/r/20210212134421.172750-2-Viktor.Rosendahl@bmw.deSigned-off-by: Viktor Rosendahl Signed-off-by: Steven Rostedt (VMware) List of files: /linux-6.15/tools/Makefile
