From dc5aef63c037562500723d0041e863a092997124 Mon Sep 17 00:00:00 2001 From: Marco Crivellari Date: Tue, 4 Nov 2025 11:39:42 +0100 Subject: [PATCH] soc/xilinx: replace use of system_unbound_wq with system_dfl_wq 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. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") system_dfl_wq should be the default workqueue so as not to enforce locality constraints for random work whenever it's not required. The old system_unbound_wq will be kept for a few release cycles.
