ASoC: SOF: ipc4: Add set_core_state pm_ops implementation

2022-06-10T12:31:41+00:00

IPC4 uses the SET_DX message to enable/disable cores managed by the DSP. The dx_state.core_mask indicates which core is going to change state, the dx_state.dx_mask is to power on (1) or off (0) the core. In the dx_mask only those bits (cores) checked which bit is set in the core_mask, other bits (cores) ignored.

ASoC: SOF: ipc: introduce cont_update_posn in sof_ipc_stream_params struct

2022-05-10T13:01:54+00:00

The host stream position is updated when no_stream_position is set as 0. However current implementation updates host stream position only when report data is larger than or equal to host period size which is decided by the period size of host side. It maybe cause host stream position update not in time. Therefore this patch introduces another field "cont_update_posn", a boolean value aimed to update host stream position continuously and based on period size of pipeline. It can get better precise when need to update host stream position from firmware.

ASoC: SOF: make struct snd_sof_dai IPC agnostic

2022-03-09T13:30:09+00:00

Remove the comp_dai and dai_config members of struct snd_sof_dai and replace it with a void *private field. Introduce a new struct sof_dai_private_data that will contain the pointer to these two fields. The topology parser will populate this structure and save it as part of the "private" member in snd_sof_dai. Change all users of these fields to use the private member instead.

ASoC: SOF: Replace zero-length array with flexible-array member

2022-02-17T17:13:36+00:00

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().
