* ASoC: SOF: Add PM supportLiam Girdwood2019-04-281-0/+385
| | | | | | | | | | | | | | | | | | | | | | Add support for saving and restoring DSP context in D3 to host DDR. The suspend callback includes: suspend all pcm's stream that are running, send CTX_SAVE ipc, drop all ipc's, release trace dma and then power off the DSP. And the resume callback performs the following steps: load FW, run FW, re-initialize trace, restore pipeline, restore the kcontrol values and finally send the ctx restore ipc to the dsp. The streams that are suspended are resumed by the ALSA resume trigger. If the streams are paused during system suspend, they are marked explicitly so they can be restored during PAUSE_RELEASE.

* ASoC: SOF: Add DSP firmware logger supportLiam Girdwood2019-04-281-0/+297
| | | | | | | | | | | | | | | | | | | | | This patch adds support for real-time DSP logging (timestamped events and bespoke binary data) for firmware debug. The current solution relies on DMA transfers to system memory that is then accessed by userspace tools such as sof-logger. For Intel platforms, two types of DMAs are currently used (GP-DMA for Baytrail/CherryTrail and HDaudio DMA for SKL+) Due to historical reasons, the driver code follows the DSP firmware conventions and refers to 'traces', but it is currently unrelated to the Linux trace subsystem. Future solutions will include support for more advanced hardware (e.g. MIPI Sys-T), additional formats and the ability to enable/disable specific traces dynamically.

| | | | | | | | | | | | SOF uses topology to define the DAPM graphs and widgets, DAIs, PCMs and set parameters for init and run time usage.

* ASoC: SOF: Add PCM operations supportLiam Girdwood2019-04-281-0/+719
| | | | | | | | | | | | | | | Add support for exposing PCMs to userspace. PCMs are defined by topology and the operations in this patch map to SOF IPC calls. The .get_module_upon_open field is set to allow for module load/unload tests. There is no risk of the sof-pci/acpi-dev module being removed while the platform components are in use. This may need to be revisited when DT platforms are supported.

| | | | | | | | | | | | | | | | | | | | | Add debugFS files that can be used to expose DSP memories and and peripherals to userspace to assist with firmware debugging. Since we cannot rely on debugFS, errors are logged but don't stop execution. When a resource cannot be read in D3, it is optionally cached on suspend. Copying memories from IO will increase the suspend latency, this should only used in engineering builds w/ debug options. This part will have to be enhanced when support for D0ix states is provided, currently only D0 and D3 are supported.

* ASoC: SOF: Add Sound Open Firmware KControl supportLiam Girdwood2019-04-281-0/+552
| | | | | | | | | | | | | | | | | | | | | | SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. The current implementation is aligned with previous Intel solutions, but is not optimal and can be improved: a) for every get/put the host wakes up the DSP and generates an IPC. The kernel should cache the values and generate an IPC only when strictly necessary. b) the firmware can be implemented to only instantiate the pipelines and related control-related parts that are needed at a given time, and power-gate the relevant SRAM blocks. The development tasks for these two improvements has started, once validated they will be provided in an update.

* ASoC: SOF: Add Sound Open Firmware driver coreLiam Girdwood2019-04-282-0/+1138
The Sound Open Firmware driver core is a generic architecture independent layer that allows SOF to be used on many different architectures and platforms. It abstracts DSP operations and IO methods so that the target DSP can be an internal memory mapped or external SPI or I2C based device. This abstraction also allows SOF to be run on many different VMs on the same physical HW. SOF also requires some data in ASoC PCM runtime data for looking up SOF data during ASoC PCM operations.
