This should not be bandwidth issue as the 4 capture pipelines take < 20% of the bandwidth.

@mwasko @slawblauciak looks like the DMIC IRQ handler again, did we not remove this since it did nothing but report an error (and consume cycles) ?
slawblauciak commentedon Mar 23, 2021
@zrombel can you try reproducing it on our RVPs?
zrombel commentedon Mar 23, 2021
Ok, will do.
mwasko commentedon Mar 23, 2021
@lgirdwood we cannot completely ignore and suppress DMIC xrun. However to avoid DMIC xrun storm of interrupts the change was introduced to stop DMIC when xrun occurs.
keyonjie commentedon Mar 24, 2021
I realize there could be this possibility for DMIC pipelines, as the DMIC is started first and DMA later. The reason we don't see this in the SSP pipelines is we are not observing xrun interrupts there.
keyonjie commentedon Mar 24, 2021
once we can reproduce this stably, maybe worth to try if the PR #3952 help.

@keqiaozhang still an issue today ?
lgirdwood commentedon May 27, 2021
@keqiaozhang @XiaoyunWu6666 still an issue today ?
keqiaozhang commentedon May 31, 2021
@lgirdwood , yes, this issue can still be reproduced on TGL-RVP-NOCODEC platform in today's CI test. Daily test ID:4290
keyonjie commentedon Jun 3, 2021
@keqiaozhang @XiaoyunWu6666 looks this is fixed according to the latest daily result, please help to double check and close it if true.

run test case 500 iterations, this issue is not reproduced, close.
