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: remove unnecessary waitq before loading firmware

2020-03-13T15:13:25+00:00

The HDA_DSP_IPC_PURGE_FW IPC from ROM is already handled in
cl_dsp_init(), and it will never be received in the IRQ thread,
so the wait condition on this IPC will never be satisfied. The
wait before loading firmware is redundant and can be removed safely.

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: Intel: cnl: Implement feature to support DSP D0i3 in S0

2020-02-11T11:48:07+00:00

This patch implements support for DSP D0i3 when the system
is in S0. The basic idea is to schedule a delayed work after
every successful IPC TX that checks if there are only
D0I3-compatible streams active and if so transition
the DSP to D0I3.

With the introduction of DSP D0I3 in S0, we need to
ensure that the DSP is in D0I0 before sending any new
IPCs. The exception for this would be the
compact IPCs that are used to set the DSP in
D0I3/D0I0 states.

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.
