ASoC: SOF: Compile and runtime IPC version selection

2022-06-14T10:22:12+00:00

The new IPC4 version is only supported by Intel platforms, iMX, AMD and MediaTek only uses the standard SOF IPC. There is no need for these platforms to build kernel support for IPC4 as it is just dead code for them. SND_SOC_SOF_IPC3 and SND_SOC_SOF_INTEL_IPC4 is introduced to allow compile time selection and exclusion of IPC implementations. To avoid randconfig failures add also support for runtime selection of the IPC ops in ipc.c based on sdev->pdata->ipc_type Signed-off-by: Peter Ujfalusi Reviewed-by: Bard Liao Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20220614075618.28605-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown

ASoC: SOF: Convert the generic probe support to SOF client

2022-02-10T15:19:12+00:00

Add a new client driver for probes support and move all the probes-related code from the core to the client driver. The probes client driver registers a component driver with one CPU DAI driver for extraction and creates a new sound card with one DUMMY DAI link with a dummy codec that will be used for extracting audio data from specific points in the audio pipeline. The probes debugfs ops are based on the initial implementation by Cezary Rojewski and have been moved out of the SOF core into the client driver making it easier to maintain. This change will make it easier for the probes functionality to be added for all platforms without having the need to modify the existing(15+) machine drivers.

ASoC: SOF: Convert the generic IPC flood test into SOF client

2022-02-10T15:19:09+00:00

Move the IPC flood test code out from the debug file as separate SOF client driver. Based on the kernel configuration, the device registration for the new IPC flood test is going to happen in the core. With the separate client driver it is going to be possible to run multiple flood tests in parallel to increase the stress, the new Kconfig option can be used to select this (defaults to 1). In order to preserve backward compatibility with existing SW/scripts, the first IPC flood test's debugfs files have been linked to the old files.

ASoC: SOF: Introduce IPC SOF client support

2022-02-10T15:19:06+00:00

A client in the SOF (Sound Open Firmware) context is a driver that needs to communicate with the DSP via IPC messages. The SOF core is responsible for serializing the IPC messages to the DSP from the different clients. One example of an SOF client would be an IPC test client that floods the DSP with test IPC messages to validate if the serialization works as expected. Multi-client support will also add the ability to split the existing audio cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated client instead of adding HDMI to all cards. This patch introduces descriptors for SOF client driver and SOF client device along with APIs for registering and unregistering a SOF client driver, sending IPCs from a client device and accessing the SOF core debugfs root entry. Along with this, add a couple of new members to struct snd_sof_dev that will be used for maintaining the list of clients.

ASoC: SOF: Kconfig: Make the SOF_DEVELOPER_SUPPORT depend on SND_SOC_SOF

2021-12-17T11:06:22+00:00

SND_SOC_SOF_DEVELOPER_SUPPORT contains options affecting how the built SOF driver stack will behave, enables debug options and other features. These options have no meaning if the SND_SOC_SOF is not even enabled. If we have SOF client options under developer_support and debug they can be selected to be built even without the core, but they do need symbols from the core (the sof-client API) which can result build failure. In Kconfig we can have SND_SOC_SOF_TOPLEVEL=y SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST=y for example, which will make the flood client to be built, but the SOF core is not as SND_SOC_SOF is not selected.
