Commit 9ee3f0d (" ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices") removed DMA wait for IPC3 case. Proceed and remove the wait for IPC4 devices as well. There is no dependency to IPC version in the load logic and checking the firmware status is a sufficient check in case of errors. The removed code also had a bug in that -ETIMEDOUT is returned without stopping the DMA transfer.

When a single-shot DMA is complete, hda_dsp_stream_get_position() will point to hstream->bufsize. Current code zeros out the returned position in this case as ALSA core does not expect to get such values in its pointer callback. While valid in the ALSA case, this is no helpful when debugging other DMA usages, e.g. firmware loading. Allow valid value of hstream->bufsize to be returned as a position.

To help debugging FW load failures, print out the last position of the DMA used to load the firmware image. This allows to see whether DMA transfer has started and whether it completed. Signed-off-by: Kai Vehmanen <[email protected]>

Example how we could add debugging tools back after the IOC check is removed. |
