ASoC: SOF: Intel: remove the HDA_DSP_CORE_MASK() macro

2020-09-11T14:29:31+00:00

Remove the HDA_DSP_CORE_MASK() macro and use BIT() and GENMASK() macros directly for more clarity.

ASoC: SOF: rename cores_mask to host_managed_cores_mask

2020-09-11T14:29:29+00:00

Rename the cores_mask in struct sof_intel_dsp_desc to host_managed_cores_mask to be more indicative of the fact that only these cores can be powered up/down by the host.

ASoC: SOF: Intel: Probe compress operations

2020-02-18T21:52:09+00:00

Add HDA handlers for soc_compr_ops and snd_compr_ops which cover probe related operations. Implementation supports both connection purposes. These merely define stream setups as core flow is covered by SOF compress core.

ASoC: SOF: move arch_ops under ops

2019-12-18T20:02:02+00:00

The current structures are not well designed. We include Xtensa information from the ACPI and PCI levels, but at the Kconfig/module level everything Xtensa related is included at the sof/intel level. Move the arch_ops under ops so that Xtensa is hidden in the DSP ops, with a structure that follows the Kconfig/module partition.

ASoC: SOF: Make creation of machine device from SOF core optional

2019-12-09T18:39:35+00:00

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.

ASoC: SOF: Intel: hda: solve MSI issues by merging ipc and stream irq handlers

2019-12-09T18:35:56+00:00

The existing code uses two handlers for a shared edge-based MSI interrupts. In corner cases, interrupts are lost, leading to IPC timeouts. Those timeouts do not appear in legacy mode. This patch merges the two handlers and threads into a single one, and simplifies the mask/unmask operations by using a single top-level mask (Global Interrupt Enable). The handler only checks for interrupt sources using the Global Interrupt Status (GIS) field, and all the actual work happens in the thread. This also enables us to remove the use of spin locks. Stream events are prioritized over IPC ones. This patch was tested with HDaudio and SoundWire platforms, and all known IPC timeout issues are solved in MSI mode. The SoundWire-specific patches will be provided in follow-up patches, where the SoundWire interrupts are handled in the same thread as IPC and stream interrupts.

ASoC: SOF: define INFO_ flags in dsp_ops

2019-10-25T10:07:45+00:00

Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined in the SOF PCM core, which doesn't scale. To account for platform variations, these flags need to be set in DSP ops. This patch only moves the definitions and does not change any functionality.
