[ 94.483736] BUG: kernel NULL pointer dereference, address: 0000000000000000 |
|
@Vamshigopal Any occurence data? Can this be reproduced? |
|
@kv2019i reproduces always, 1/1 tries arecord -Dhw:0,6 -f s16_le -c 2 -r 48000 /tmp/rec.wav localhost ~ # arecord -l |
|
@kv2019i if we use RPL001 FW ( tried on ADL -P) with below kernel, then the panic comes on boot itself. Same signature. https://github.com/dineshXadireddi/Backport-series/commits/working_branch_New_Nov26 is the kernel used for v5.10 |
|
it fails exactly when finding BE for corresponding FE |
|
I could reproduce the problem. It seems there are multiple issues in upstream kernel with this topology. The use-case does work if playback is started first on PCM0, but the mechanism to return -ENODATA on PCM6 if PCM0 is not running, is not working correctly. I'll send a PR to fix the kernel issue (so it doesn't crash), but it would seem additional fixes are needed on FW side. CRAS should open the PCMs in correct order though (the oops needs to be fixed of course). |
|
@kv2019i the sequence in CRAS is to start this only after starting speaker playback. But there should be no panic on starting this out of sequence. Error out is the right way. |

#4085 fixes the kernel oops. I'm still looking at why FW times out to TRIG_STOP after -ENODATA. |
If pipeline trigger fails, the pipeline state may be left in intermediate state like COMP_TRIGGER_PRE_START. This is a problem in case a new trigger is sent to the same pipeline. The pipeline state may indicate the pipeline task is running, while in practise this is not the case. This can lead to IPC timeout as the trigger is incorrectly sent to delayed processing in the pipeline task (which is not running). One case is the echo reference capture pipeline. This pipeline will return -ENODATA in case the linked playback pipeline is not running. Host may send a TRIG_STOP for the pipeline, and this will lead to IPC timeout: [ 100212.287685] ( 20.468750) c0 pipe 9.47 ..../pipeline-schedule.c:64 ERROR pipeline_task_cmd(): failed to trigger components: -61 [ 100233.121017] ( 20.833332) c0 ll-schedule ./schedule/ll_schedule.c:142 INFO task complete 0xbe1d00c0 pipe-task <f11818eb-e92e-4082-82a3-dc54c604ebb3> [ 100251.766850] ( 18.645832) c0 ll-schedule ./schedule/ll_schedule.c:145 INFO num_tasks 2 total_num_tasks 2 [ 163209.316431] ( 62957.550781) c0 ipc src/ipc/ipc3/handler.c:1576 INFO ipc: new cmd 0x60050000 [ 163237.441430] ( 28.124998) c0 pipe 9.47 ....../pipeline-stream.c:261 INFO pipe trigger cmd 0 Firmware will be stuck here as the command is never handled.

FW side fix to handle the IPC timeout -> thesofproject/sof#6753 |

@Vamshigopal can you clarify which machine driver is used for this platform? I'd like to make sure the dailink used for the speaker is declared with both dpcm_playback and dpcm_capture = 1; Thanks! |
|
@plbossart i'm seeing this on max98360a. i think Vamshi also seeing on the maxim codec only. |
|
@plbossart i can see only dpcm_playback=1 is declared for speaker. for smart amp speakers like max98373 both dpcm_playback and dpcm_capture=1 are declared. |
|
I think @plbossart you are aware of the Echo ref design on dump codecs, just to bring this to context here on Dumb codec, we provide the playback data back to Echo ref PCM. So from cras the logic ensures Echo ref is started only after speaker starts and stops also together. But if we manually open the Echo ref PCM, we are seeing this panic. This is not a valid scenario, but we should err out rather than panic and reboot. 1 more observation is when i use same kernel stack with RPL001 FW, i see the same panic on boot itself - i dont need to open the Echo ref PCM for triggering the panic. I'm trying to understand whats changed there as well. |

UPDATE: moved the comment #4085 pull request |
|
@Vamshigopal can you add dpcm_capture = 1 for the dailink and recheck if that makes the kernel oops go away. If yes, that would confirm my analysis that the be_substream is not allocated because the substream count is zero in that case. |
The amplifier may provide hardware support for I/V feedback, or alternatively the firmware may generate an echo reference attached to the SSP and dailink used for the amplifier. To avoid any issues with invalid/NULL substreams in the latter case, always unconditionally set dpcm_capture. Link: thesofproject#4083 Signed-off-by: Pierre-Louis Bossart <[email protected]>

@Vamshigopal @sathyap-chrome please try #4092, this should fix things for you. @kv2019i PR #4085 is very much needed to deal with invalid configurations, but those configurations should be fixed in the first place when they are known. |
A BE is used without an allocated substream is either an error case or a configuration where the BE is notional, e.g. for DSP-generated echo reference. The existing code has multiple filters in startup/trigger, this patch suggesting plugging the remaining holes in DAI hw_params and stop cases.

@plbossart with #4092 changes i have below observation.
|
|
@Vamshigopal that's a different problem you are reporting, no? I see an IPC error. What happens if you only apply PR #4085 and run the same tests? |

Steps to reproduce:
start echo reference capture
Expected result:
Echo reference capture should take the feedback from speaker.
Actual result:
Seeing BUG: kernel NULL pointer dereference, address: 0000000000000000
with kernel panic.
