First there is a compilation error that needs to be fixed:

does this mean it is no longer up to the IPC messages to allocate the buffers?

@cujomalainey sorry not following the question. Which buffers are you alluding to? This list of buffers is a replacement for mod->local_buff which assumes there's only one sink for a module. So we expand it to a list to support multiple sinks

what does mean "support multiple sinks".?

@lenghonglin imagine a demux where you can have a single source split and copied to multiple sinks. Thats is what I mean by "support multiple sinks"

Add a sink_buffer_list to struct processing_module to support multiple output buffers for modules. Allocate sink buffers for all sinks during prepare and copy the produced samples from the output_buffers into the respective sink buffers during copy.

Add a helper function to copy from local buffer to the sink buffer. This will be used to copy from all output buffers. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Modify all codec implementations to copy the produced samples to the output_buffer. Copy the produced samples from all output buffers in the sink_buffer_list. Remove local_buff from struct processing_module as it is no longer needed. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

@markbartonxperi can you please check if this PR works for you?

markbartonxperi · 2022-03-18T08:58:15Z

@ranj063 Looks good. Thanks!

dbaluta

Thanks @ranj063 this works fine for i.MX. Also, incremental patches compile fine.

lgirdwood · 2022-03-18T14:47:55Z

CI looks good.

+
+copy_period:
+	comp_get_copy_limits_with_lock(src_buffer, sink_buffer, &cl);
+	copy_bytes = cl.frames * cl.source_frame_bytes;


What if copy_bytes is zero?

I dont think you can get here is copy_bytes is 0. we get to this point only if audio_stream_get_avail_bytes(&src_buffer->stream) conditions above are met

for dai comp, if comsumer(codec) slow than producter(codec_adapter), the dai buffer will be fulled, so in this condition, copy_bytes should be 0.

@lenghonglin even if copy_bytes is 0, the operations below will return without doing anything in that case. But sure, I can add a check for this in a follow up PR

hlleng · 2022-03-22T08:52:55Z

There is another thing that i wanna disscuss.
For example, the mp3 is mpeg2 layer 3 16k 16bit . so codec_adapter input size is 72 bytes, output size is 1152 bytes. and the comp buffer size is 4k.
when host send TRIGER_STOP. there is 4k buffer in sof is not to be comused

So what time for host to send TRIGER_STOP?

dbaluta · 2022-03-22T08:55:34Z

So, you say that we don't play the entire mp3 file till the end right? I think the solution here is to implement DRAIN. Patches are welcomed if you can implement this.

I have this on my todo list but with low prio this quarter.

hlleng · 2022-03-22T09:13:58Z

ok, i will add this thing in my todolist
