ASoC: SOF/Intel: clarify SPDX license with GPL-2.0-only

2020-05-01T16:45:24+00:00

Remove the ambiguity with GPL-2.0 and use an explicit GPL-2.0-only
tag.

ASoC: SOF: Intel: Probe compress operations

2020-02-18T21:52:09+00:00

Add HDA handlers for soc_compr_ops and snd_compr_ops which cover probe
related operations. Implementation supports both connection purposes.
These merely define stream setups as core flow is covered by SOF
compress core.

ASoC: SOF: move arch_ops under ops

2019-12-18T20:02:02+00:00

The current structures are not well designed. We include Xtensa
information from the ACPI and PCI levels, but at the Kconfig/module
level everything Xtensa related is included at the sof/intel level.

Move the arch_ops under ops so that Xtensa is hidden in the DSP ops,
with a structure that follows the Kconfig/module partition.

ASoC: SOF: Make creation of machine device from SOF core optional

2019-12-09T18:39:35+00:00

Currently, SOF probes machine drivers by creating a platform device
and passing the machine description as private data.

This is driven by the ACPI restrictions. Ideally, ACPI tables
should contain the description for the machine driver. This is
not possible because ACPI tables are frozen and used on multiple
OS-es (e.g Windows).

In the case of Device Tree we don't have this restriction, so we
choose to probe the machine drivers by creating a DT node as is
the standard ALSA way.

This patch makes the probing of machine drivers from SOF
core optional allowing for Device Tree platforms to decouple
the SOF core from machine driver probing.

Along with this, it also consolidates the machine driver selection
for Intel platforms by defining optional ops for selecting the machine
driver based on the ACPI match for HDA and non-HDA platforms and
setting the mach params.

ASoC: SOF: Intel: hda: solve MSI issues by merging ipc and stream irq handlers

2019-12-09T18:35:56+00:00

The existing code uses two handlers for a shared edge-based MSI interrupts.
In corner cases, interrupts are lost, leading to IPC timeouts. Those
timeouts do not appear in legacy mode.

This patch merges the two handlers and threads into a single one, and
simplifies the mask/unmask operations by using a single top-level mask
(Global Interrupt Enable). The handler only checks for interrupt
sources using the Global Interrupt Status (GIS) field, and all the
actual work happens in the thread. This also enables us to remove the
use of spin locks. Stream events are prioritized over IPC ones.

This patch was tested with HDaudio and SoundWire platforms, and all
known IPC timeout issues are solved in MSI mode. The
SoundWire-specific patches will be provided in follow-up patches,
where the SoundWire interrupts are handled in the same thread as IPC
and stream interrupts.

ASoC: SOF: define INFO_ flags in dsp_ops

2019-10-25T10:07:45+00:00

Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined
in the SOF PCM core, which doesn't scale. To account for platform
variations, these flags need to be set in DSP ops.

This patch only moves the definitions and does not change any
functionality.

ASoC: SOF: Intel: implement runtime idle for CNL/APL

2019-07-06T11:23:47+00:00

Implement runtime idle for CNL/APL devices using similar runtime
PM idle logic as the Intel AZX HDA driver. If any HDA codecs are
powered when runtime suspend request comes, return -EBUSY. By doing
this, strict ordering is enforced between HDA codec and the HDA
controller.
