2021-02-11ASoC: SOF: relax ABI checks and avoid unnecessary warningsKai Vehmanen
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.

2020-03-02ASoC: SOF: ipc: check ipc return value before data copyJaska Uimonen
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.

2020-02-11ASoC: SOF: Intel: cnl: Implement feature to support DSP D0i3 in S0Ranjani Sridharan
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.

2019-12-18ASoC: SOF: Introduce state machine for FW bootRanjani Sridharan
Add a state machine for FW boot to track the different stages of FW boot and replace the boot_complete field with fw_state field in struct snd_sof_dev. This will be used to determine the actions to be performed during system suspend. One of the main motivations for adding this change is the fact that errors during the top-level SOF device probe cannot be propagated and therefore suspending the SOF device normally during system suspend could potentially run into errors. For example, with the current flow, if the FW boot failed for some reason and the system suspends, the SOF device suspend could fail because the CTX_SAVE IPC would be attempted even though the FW never really booted successfully causing it to time out. Another scenario that the state machine fixes is when the runtime suspend for the SOF device fails and the DSP is powered down nevertheless, the CTX_SAVE IPC during system suspend would timeout because the DSP is already powered down.

Move all the audio-specific code in the core, audio-specific logic in the top-level PM callbacks and the core header files into a separate file (sof-audio.*) in preparation for adding an audio client device. In the process of moving all structure definitions for widget, routes, pcm's etc, the snd_sof_dev member in all these structs is replaced with the snd_soc_component member. Also, use the component device instead of the snd_sof_dev device wherever possible in the PCM component driver, control IO functions and the topology parser as the component device will be moved over to the client device later on.

2019-05-28ASoC: SOF: ipc: fix a race, leading to IPC timeoutsGuennadi Liakhovetski
Currently on all supported platforms the IPC IRQ thread first signals the sender when an IPC response is received from the DSP, then unmasks the IPC interrupt. Those actions are performed without holding any locks, so the thread can be interrupted between them. IPC timeouts have been observed in such scenarios: if the sender is woken up and it proceeds with sending the next message without unmasking the IPC interrupt, it can miss the next response. This patch takes a spin-lock to prevent the IRQ thread from being preempted at that point. It also makes sure, that the next IPC transmission by the host cannot take place before the IRQ thread has finished updating all the required IPC registers.
