[BUG][TGL] multi-pipeline playback or capture failed with 'DSP panic' #1924
Description
Describe the bug
Running multiple pipelines can cause DSP Panic on TGL.
To Reproduce
Scenario 1:
Playback via headset (device 0,0) and HDMI monitor (device 0,4) simultaneously.
- In terminal to run "aplay -D hw:0,0 -f dat 48California_Dreaming.wav"
- In other terminal to run "aplay -D hw:0,4 -f dat 48California_Dreaming.wav"
Scenario 2:
Playback and capture via headset simultaneously.
- In terminal to run "aplay -D hw:0,0 -f dat 48California_Dreaming.wav"
- In other terminal to run "arecord -Dhw:0,0 -fs16_le -c2 -r 48000 -vv -i test.wav"
Reproduction Rate
100%
Expected behavior
Can run multi-pipeline on TGL
Actual Result
DSP Panic will happen when starting the 2nd pipeline

@Bin-QA Repro recipe is incomplete - What kernel did you use?
jajanusz commentedon Oct 14, 2019
@Bin-QA We don't work on BUGs with kernel that we don't have, if you want us to reproduce error, please give commit hash of kernel that you see error with.

Please check on a timer-driven pipeline, with SSP or SDW.
To make a pipeline timer-driven in the topology, the 11th param ('time_domain') of PIPELINE_PCM_ADD has to be set to SCHEDULE_TIME_DOMAIN_TIMER.
For reference:

@jajanusz Can you try to dump the exception with sof-coredump-to-gdb.sh?
The exception is attached.
