Below is a summary of a discussion about the Workqueue API and cpu isolation considerations. Details and more information are available here: "workqueue: Always use wq_select_unbound_cpu() for WORK_CPU_UNBOUND." https://lore.kernel.org/all/20250221112003.1dSuoGyc@linutronix.de/ === Current situation: problems === Let's consider a nohz_full system with isolated CPUs: wq_unbound_cpumask is set to the housekeeping CPUs, for !WQ_UNBOUND the local CPU is selected. This leads to different scenarios if a work item is scheduled on an isolated CPU where "delay" value is 0 or greater then 0: schedule_delayed_work(, 0); This will be handled by __queue_work() that will queue the work item on the current local (isolated) CPU, while: schedule_delayed_work(, 1); Will move the timer on an housekeeping CPU, and schedule the work there. Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. === Plan and future plans === This patchset is the first stone on a refactoring needed in order to address the points aforementioned; it will have a positive impact also on the cpu isolation, in the long term, moving away percpu workqueue in favor to an unbound model. These are the main steps: 1) API refactoring (that this patch is introducing) - Make more clear and uniform the system wq names, both per-cpu and unbound. This to avoid any possible confusion on what should be used. - Introduction of WQ_PERCPU: this flag is the complement of WQ_UNBOUND, introduced in this patchset and used on all the callers that are not currently using WQ_UNBOUND. WQ_UNBOUND will be removed in a future release cycle. Most users don't need to be per-cpu, because they don't have locality requirements, because of that, a next future step will be make "unbound" the default behavior. 2) Check who really needs to be per-cpu - Remove the WQ_PERCPU flag when is not strictly required. 3) Add a new API (prefer local cpu) - There are users that don't require a local execution, like mentioned above; despite that, local execution yeld to performance gain. This new API will prefer the local execution, without requiring it. === Introduced Changes by this patchset === 1) [P 1-2-3] system workqueue rename: system_wq is a per-CPU workqueue, but his name is not clear. system_unbound_wq is to be used when locality is not required. Because of that, system_wq has been renamed in system_percpu_wq, while system_unbound_wq is now system_dfl_wq. The old wq are still around, but if used in queue_work(), a pr_warn_once() will be printed and the wq used is automatically assigned to the new default (system_dfl_wq or system_percpu_wq). 2) [P 4] Introduction of WQ_PERCPU. This patch adds the new WQ_PERCPU flag to explicitly require to be per-cpu. Every alloc_workqueue() caller should use one among WQ_PERCPU or WQ_UNBOUND. This is actually enforced warning if both or none of them are present at the same time. WQ_UNBOUND will be removed in a next release cycle. [P 5-6-7-8] WQ_PERCPU to alloc_workqueue callers This patches adds to every alloc_workqueue() caller that require it, the new WQ_PERCPU flag. This is done in separate patches for 3 different subsystem: mm, fs, net. P 7 introduce the change to all the remaining callers. 3) [P 9] WQ_PERCPU documented in workqueue.rst Added a short section about WQ_PERCPU and a Note under WQ_UNBOUND mentioning that it will be removed in the future. --- Changes in v3: - The introduction of the new wq(s) and the WQ_PERCPU flag have been moved in separated patches (1 for wq(s) and 1 for WQ_PERCPU). - WQ_PERCPU is now added to all the alloc_workqueue callers in separated patches addressing few subsystems first (fs, mm, net). Changes in v2: - Introduction of WQ_PERCPU change has been merged with the alloc_workqueue() patch that pass the WQ_PERCPU flag explicitly to every caller. - (2 drivers) in the code not matched by Coccinelle; WQ_PERCPU added also there. - WQ_PERCPU added to __WQ_BH_ALLOWS. - queue_work() now prints a warning (pr_warn_once()) if a user is using the old wq and redirect the wrong / old wq to the new one. - Changes to workqueue.rst about the WQ_PERCPU flag and a Note about the future of WQ_UNBOUND.
