[PATCH 0/8] Changes to SOF kcontrol data set/get ops

[PATCH 0/8] Changes to SOF kcontrol data set/get ops

[Ranjani Sridharan]

This set of patches deals with modifications to the signature of kcontrol
get/set data functions to make them more intuitive. The last patch deals
with initializing the binary control data size after boot up.

Peter Ujfalusi (7):
  ASoC: SOF: ipc: Rename send parameter in
    snd_sof_ipc_set_get_comp_data()
  ASoC: SOF: Drop ipc_cmd parameter for snd_sof_ipc_set_get_comp_data()
  ASoC: SOF: topology: Set control_data->cmd alongside scontrol->cmd
  ASoC: SOF: Drop ctrl_cmd parameter for snd_sof_ipc_set_get_comp_data()
  ASoC: SOF: sof-audio: Drop the `cmd` member from struct
    snd_sof_control
  ASoC: SOF: control: Do not handle control notification with component
    type
  ASoC: SOF: Drop ctrl_type parameter for
    snd_sof_ipc_set_get_comp_data()

Ranjani Sridharan (1):
  ASoC: SOF: topology: read back control data from DSP

[PATCH 1/8] ASoC: SOF: ipc: Rename send parameter in snd_sof_ipc_set_get_comp_data()

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

Rename the send parameter to set in snd_sof_ipc_set_get_comp_data() and
sof_set_get_large_ctrl_data() to be more aligned with the function name.

No functional change.

[PATCH 2/8] ASoC: SOF: Drop ipc_cmd parameter for snd_sof_ipc_set_get_comp_data()

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

The correct ipc_cmd can be selected based on the `ctrl_cmd` and the `set`
parameters:
if the ctrl_cmd is SOF_CTRL_CMD_BINARY then SOF_IPC_COMP_*_DATA
otherwise SOF_IPC_COMP_*_VALUE.

The SET or GET direction can be selected with the use of `set` parameter.

[PATCH 3/8] ASoC: SOF: topology: Set control_data->cmd alongside scontrol->cmd

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

Set the scontrol->control_data->cmd early to the same as scontrol->cmd.

This is a preparatory patch to remove the ctrl_cmd parameter for the
snd_sof_ipc_set_get_comp_data() function.

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

The scontrol->control_data->cmd has been configured during initialization
to the correct sof_ipc_ctrl_cmd.

No need to pass duplicated information, let's use the already available
one via scontrol.

[PATCH 5/8] ASoC: SOF: sof-audio: Drop the `cmd` member from struct snd_sof_control

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

There is no need to use two variables to store and check the same
information, the scontrol->cmd is the same as scontrol->control_data->cmd.

Drop the former one and when it is needed, access the cmd from the
control_data.

[PATCH 6/8] ASoC: SOF: control: Do not handle control notification with component type

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

The component type is not used in firmware nor in the kernel currently and
it is not even clear how it should be handled.

Do not even try to handle it to avoid errors.

[PATCH 7/8] ASoC: SOF: Drop ctrl_type parameter for snd_sof_ipc_set_get_comp_data()

[Ranjani Sridharan]

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

The SOF_CTRL_TYPE_VALUE_COMP_* type is not used by the firmware nor in the
kernel side.
It is also not clear what action should be taken for such type.

With this in mind:
The correct ipc_cmd can be selected based on the `ctrl_cmd` and the `set`
parameters:
if the ctrl_cmd is SOF_CTRL_CMD_BINARY then SOF_CTRL_TYPE_DATA_*
otherwise SOF_CTRL_TYPE_VALUE_CHAN_*.

The SET or GET direction can be selected with the use of `set` parameter.

[PATCH 8/8] ASoC: SOF: topology: read back control data from DSP

[Ranjani Sridharan]

Read back the control data from the DSP to initialize the control data
size to match that of the data in the DSP. This is particularly useful
for volatile read-only kcontrols in static pipelines.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
