platform: surface: replace use of system_wq with system_percpu_wq

2025-11-28T10:07:02+00:00

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.

platform/surface: acpi-notify: add WQ_PERCPU to alloc_workqueue users

2025-11-28T10:06:58+00:00

This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The refactoring is going to alter the default behavior of alloc_workqueue() to be unbound by default. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. For more details see the Link tag below. In order to keep alloc_workqueue() behavior identical, explicitly request WQ_PERCPU.

platform/surface: aggregator: Omit a variable reassignment in ssam_serial_hub_probe()

2025-11-05T08:50:00+00:00

An error code was assigned to a variable and checked accordingly. This value was passed to a dev_err_probe() call in an if branch. This function is documented in the way that the same value is returned. Thus delete a redundant variable reassignment. The source code was transformed by using the Coccinelle software.

ACPI: platform_profile: Remove platform_profile_handler from exported symbols

2025-01-17T17:15:59+00:00

In order to protect the platform_profile_handler from API consumers, allocate it in platform_profile_register() and modify it's signature accordingly. Remove the platform_profile_handler from all consumer drivers and replace them with a pointer to the class device, which is now returned from platform_profile_register(). Replace *pprof with a pointer to the class device in the rest of exported symbols.

ACPI: platform_profile: Add `probe` to platform_profile_ops

2025-01-16T15:26:30+00:00

Add a `probe` callback to platform_profile_ops, which lets drivers initialize the choices member manually. This is a step towards unexposing the struct platform_profile_handler from the consumer drivers.
