ASoC: SOF: relax ABI checks and avoid unnecessary warnings

2021-02-11T17:31:56+00:00

With recent SOF 1.7 pre-releases, kernel has been emitting following warnings at probe: [10006.645216] sof-audio-pci 0000:00:1f.3: warn: FW ABI is more recent than kernel [10006.652137] sof-audio-pci 0000:00:1f.3: warn: topology ABI is more recent than kernel The warnings are emitted due to increase of the patch-level in firmware mainline (to 3.17.1). But the patch level should not be considered even in the strict ABI check, so modify the kernel side logic that makes the check and only consider the major.minor components.

ASoC: SOF: IPC: reduce verbosity of IPC pointer updates

2020-08-25T19:39:37+00:00

When using dynamic debug, the console is swamped with verbose position pointer logs, which really don't add much information. Move then to vdbg to keep traces usable and allow for easier end-user support.

ASoC: SOF: ipc: ignore DSP replies received when they are not expected

2020-05-27T13:06:57+00:00

We currently ignore the reply messages from the DSP when they are not expected but call it out as an error. Change the error message to a debug message.

ASoC: SOF: ipc: check ipc return value before data copy

2020-03-02T14:13:48+00:00

In tx_wait_done the ipc payload is copied before the DSP transaction error code is checked. This might lead to corrupted data in kernel side even though the error would be handled later. It is also pointless to copy the data in case of error. So change the order of error check and copy.

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.
