ASoC: SOF/Intel: clarify SPDX license with GPL-2.0-only

2020-05-01T16:45:24Z

Remove the ambiguity with GPL-2.0 and use an explicit GPL-2.0-only tag.

ASoC: SOF: Intel: remove unnecessary waitq before loading firmware

2020-03-13T15:13:25Z

The HDA_DSP_IPC_PURGE_FW IPC from ROM is already handled in cl_dsp_init(), and it will never be received in the IRQ thread, so the wait condition on this IPC will never be satisfied. The wait before loading firmware is redundant and can be removed safely.

ASoC: SOF: Intel: hda: remove unnecessary ROM IPC filter function

2020-03-13T15:13:24Z

The HDA_DSP_IPC_PURGE_FW IPC from ROM is already handled in cl_dsp_init(), and as IPC IRQ is disabled at this stage, this IPC will be never received in the IRQ thread. The function hda_dsp_ipc_is_sof for filtering the ROM IPC can be removed safely.

ASoC: SOF: Implement Probe IPC API

2020-02-18T21:52:06Z

Add all required types and methods to support each and every request that driver could sent to firmware. Probe is one of SOF firmware features which allows for data extraction and injection directly from or to DMA stream. Exposes eight IPCs: - addition and removal of injection DMAs - addition and removal of probe points - info retrieval of injection DMAs and probe points - probe initialization and cleanup Signed-off-by: Cezary Rojewski Acked-by: Pierre-Louis Bossart Link: https://lore.kernel.org/r/20200218143924.10565-5-cezary.rojewski@intel.com Signed-off-by: Mark Brown

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

2019-12-09T18:35:56Z

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: Intel: hda: Use generic function for fw ready / mem windows creation

2019-08-09T12:25:22Z

We can use generic sof_fw_ready function and reduce code duplication. Careful here that we need to provide the implementation for get_mailbox_offset and get_window_offset.

ASoC: SOF: Intel: hda: remove misleading error trace from IRQ thread

2019-07-23T11:16:53Z

Downgrade "nothing to do in IRQ thread" message from error to a debug message in the IPC interrupt handler thread. The spurious wake-up can happen if a HDA stream interrupt is raised while the IPC interrupt thread is running. IPC functionality is not impacted by this condition, so debug is a more appropriate trace level.

ASoC: SOF: Intel: ipc: don't check for HIPCCTL register value

2019-06-03T16:49:17Z

The HIPCCTL register controls the IPC interrupts. It can be set or cleared to mask or enable these interrupts, but it makes no sense to read and test its fields in an interrupt (which can only executed if its fields are set). Signed-off-by: Pierre-Louis Bossart Signed-off-by: Mark Brown
