ASoC: SOF: dai-intel: add SOF_DAI_INTEL_SSP_CLKCTRL_MCLK/BCLK_ES bits

2021-10-05T12:08:13+00:00

Add two clks_control bits. MCLK and/or BCLK will start during hw_params
and stop during hw_free if the corresponding bit is set.

While the kernel does not do anything with these bitfields, this is
also tagged as part of the ABI 3.19 changes.

ASoC: SOF: dai: include new flags for DAI_CONFIG

2021-10-05T12:08:11+00:00

Mirror changes done in SOF tree. The changes do not rely on
BIT/GENMASK on purpose to keep the structure and flags common with the
firmware tree.

The DAI_CONFIG IPC is currently used in multiple ways. It is sent to
the DSP firmware when enabling static or dynamic pipelines, in
hw_params or prepare callbacks for Intel SSP, HDaudio and ALH, on
trigger_stop and hw_free.

This IPC has been abused a bit in the past, i.e. the values used for
some of the DAI-specific fields are used to either allocate or free
resources. Two typical examples are Intel HDaudio and SoundWire/ALH
DAIs, where using a zero DMA channel number or stream tag signals to
the firmware the DMA channels or tags allocated earlier can be freed.

Rather than add a new IPC for 'hw_params' and 'hw_free', this patch
suggests supporting a 2-bit value conveying the 'stage' information in
an existing IPC structure. Only 3 possible values are used.

The mapping between HW_PARAMS and HW_FREE flags and ALSA definitions
is not strictly 1:1, e.g. in some cases the HW_PARAM flag might be set
during the .prepare callback, while the HW_FREE might be sent during the
ALSA .trigger for stop/suspend.

The semantics of the flags is to reserve and start/stop all needed
resources, typically hardware related such as DMAs or clocks, when the
HW_PARAMS is set, while the HW_FREE flag allows the firmware to
release the resources allocated. The data transfers are still
controlled within the firmware through the propagation of the trigger
command.

The driver can then pass information that the DAI_CONFIG was invoked
in e.g. a pipeline/DAI setup, hw_params or hw_free stage without
having to use a special DAI-specific encoding. Unfortunately we can't
remove old encodings due to backwards-compatibility requirements but
for new cases, such as the SSP in follow-up patches, we can make the
IPC less cryptic.

This change is tagged as ABI 3.19 and is completely backwards compatible.

ASoC: SOF: dai: mirror group_id definition added in firmware

2021-10-05T12:08:10+00:00

This was added in ABI 3.17 but never added to the kernel tree. The
group_id is not currently used but this patch is required before
additional changes.

ASoC: SOF: trace: Add runtime trace filtering mechanism

2020-12-07T14:22:05+00:00

The "filter" debugfs file defines the log levels used by
the firmware and reported by sof-logger.

The file contains the formatted entry list, where each entry
follows the following syntax in plain text:
log_level uuid_id pipe_id comp_id;

This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.

An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.

When the file is modified, an IPC command is sent to FW with new
trace levels for selected components in filter elements list.
