@ZhendanYang adding a little more context shows it's related to trace init on the first one. |
|
and on APL it is a topology loading issue So this issue is really 2 issues, one for trace init on BYT and the other for topology on APL. |
|
Add BYT DSP panic info: 942 static inline uint32_t arch_interrupt_global_disable(void) |
|
Another Exception Cause on UP2: [ 6.132460] sof-audio sof-audio: ipc tx: 0x80010000 be0166d4: 3f29a2 l32i a10, a9, 252 Test env: |

@keqiaozhang Could you share more analysis info why this is a kernel driver issue? |
|
I tested latest master FW and kernel with hda topology on WHL, no such issue |
|
sorry, with PR:thesofproject/linux#194 and thesofproject/linux#192 |
|
I test latest master FW and kernel with PR 194 and 192 on up2 and minnowboard. This issue still exist. |
|
@RanderWang yep, I see it on up^2 too - looks like something with the topology loading. |
|
@ranj063 Would you please share your finding on kernel side? |
|
we need to make logger work on DSP panic to debug this issue. Please track logger fix on thesofproject/linux#233 |
|
I did some debug on this bug these days. And here is some finding:
|
|
@libinyang please check if #518 improve the logger for your debugging. |
|
@libinyang thesofproject/linux#237 is to fix the logger failure |
|
The bug can still be found: |

@markyang please also make sure you include the context prior to the crash This shows the stream tag is wrong for DMA trace which probably causes the panic |

@Jiangxinx please use markdown when pasting logs - see my above changes. |
|
Move topology issue on up2 to #539 . |
|
It seems this bug is assigned to me. I will debug this issue after I finish some other issues on UP2. |
