2020-02-11ASoC: SOF: Move DSP power state transitions to platform-specific opsRanjani Sridharan1-7/+9
The DSP device substates such as D0I0/D0I3 are platform-specific. Therefore, the d0_substate field of struct snd_sof_dev is replaced with the dsp_power_state field which represents the current state of the DSP. This field holds both the device state and the platform-specific substate values. With the DSP device substates being platform-specific, the DSP power state transitions need to be performed in the platform-specific suspend/resume ops as well. In order to achieve this, the ops signature has to be modified to pass the target device state as an argument. The target substate will be determined by the platform-specific ops before performing the transition. For example, in the case of the system suspending to S0IX, the top-level SOF device suspend callback needs to only determine if the DSP will be entering D3 or remain in D0. The target substate in case the device needs to remain in D0 (D0I0 or D0I3) will be determined by the platform-specific suspend op. With the addition of the extended set of power states for the DSP, the set_power_state op for HDA platforms has to be extended to handle only the appropriate state transitions. So, the implementation for the Intel HDA platforms is also modified.

2019-12-09ASoC: SOF: Make creation of machine device from SOF core optionalDaniel Baluta1-0/+34
Currently, SOF probes machine drivers by creating a platform device and passing the machine description as private data. This is driven by the ACPI restrictions. Ideally, ACPI tables should contain the description for the machine driver. This is not possible because ACPI tables are frozen and used on multiple OS-es (e.g Windows). In the case of Device Tree we don't have this restriction, so we choose to probe the machine drivers by creating a DT node as is the standard ALSA way. This patch makes the probing of machine drivers from SOF core optional allowing for Device Tree platforms to decouple the SOF core from machine driver probing. Along with this, it also consolidates the machine driver selection for Intel platforms by defining optional ops for selecting the machine driver based on the ACPI match for HDA and non-HDA platforms and setting the mach params.

2019-07-23ASoC: SOF: Introduce snd_sof_dsp_get_bar_index opsDaniel Baluta1-0/+19
FW encapsulates information about section types (e.g DRAM, IRAM) inside module block header. This information can be used in order to correctly load the section to the appropriate place in memory. SOF Linux driver needs to know for each platform how to map the section type with the corresponding memory BAR. So, this patch introduces get_bar_index, a new operation inside snd_sof_dsp_ops. Intel platforms, usually load all the section in a contiguous memory area (usually denoted by sdev->mmio_bar) so things are relatively simple there. Anyhow, on i.MX8 IRAM and DRAM for example are mapped to distinct BARs. By default, if no get_bar function is provided the core implementation will always return sdev->mmio_bar so that there will be no need for a change to existing Intel code.

2019-05-03ASoC: SOF: intel: hda: add hw_params_upon_resume flag for hda streamRanjani Sridharan1-0/+6
The prepare() ioctl for BE dai link gets called both when the stream is started and when it is resumed from suspend. SOF uses this ioctl to set the hw params again only if the stream has been suspended. When the stream is started, the hw_params ioctl gets called before prepare() and hw_params is set for the BE dai link. So the prepare call does not need to do anything further. When the stream resumes after system suspend, SOF requires that the hw_params be set again for the BE dai. In order to determine which streams should set the hw params during prepare(), an internal flag called "hw_params_upon_resume" is introduced in struct sof_intel_hda_stream. The flag is set for hda streams when the sof device suspends and is cleared after hw_params is set.
