Subject: [PATCH v3 2/4] drm/amdgpu: replace use of system_wq with system_dfl_wq
Date: Wed, 24 Dec 2025 15:47:06 +0100 [thread overview]
Message-ID: <20251224144708.61167-3-marco.crivellari@suse.com> (raw)
In-Reply-To: <20251224144708.61167-1-marco.crivellari@suse.com>
This patch continues the effort to refactor workqueue APIs, which has begun
with the changes 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")
The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.
Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:
system_wq -> system_percpu_wq
system_unbound_wq -> system_dfl_wq
This way the old obsolete workqueues (system_wq, system_unbound_wq) can be
removed in the future.
