ASoC: replace use of system_wq with system_dfl_wq

2025-10-15T09:47:31Z

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. system_wq is a per-CPU worqueue, replaced by system_percpu_wq. Despite that, system_wq in this change has been replaced by system_dfl_wq, because there aren't per-cpu variables. The old wq will be kept for a few release cylces.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

ALSA/ASoC: Intel: clarify Copyright information

2024-05-07T01:37:51Z

Merge series from Pierre-Louis Bossart : This patchset does not change any functionality. It only clarifies the Copyright information in ASoC/HDAudio contributions, where an "All rights reserved" notice was mistakenly added in a number of files over the years, likely due to copy/paste. The Intel template never included this statement.

ASoC: SOF: Intel: clarify Copyright information

2024-05-06T14:59:35Z

For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

ASoC: SOF: Intel: start splitting top-level from common parts

2024-05-05T14:45:45Z

The existing code relies on the 'HDA_COMMON' module and namespace. We need to start splitting top-level parts from the low-level ones, otherwise we will not be able to reuse the low-level parts DMA support for SoundWire/BPT. In the end the dependencies will be: +----------------------------------------------+ | | | v sof-pci-intel-xxx --> sof-intel-hda ------------> sof-hda-common | ^ | | +-> soundwire_intel --> sof_hda_sdw_bpt This patch adds the initial split between the sof-pci-intel-xxx modules and the common parts, in a follow-up patch we will further split the HDA_COMMON parts Since the PCI modules are not all independent, i.e. the CNL parts are also used in JSL and TGL, additional Kconfig and namespace modules were added.

ASoC: SOF: Intel: hda: make DSPless mode work with DSP disabled in BIOS

2023-04-04T11:42:37Z

When the DSP is disabled in the BIOS, the DSP_BAR and PP_BAR cannot be accessed. One possible objection noted in initial reviews is that this patch adds a number of branches. However the number of branches is actually limited in probe/suspend/resume routines mostly, so there isn't really a degradation in terms of readability and maintainability. Adding yet another level of abstraction/ops/callbacks would increase complexity and not really help in terms of code reuse or readability and maintainability. A split between controller and DSP driver would be even more invasive.
