[Query] How can I use sof-logger with Zephyr .ri image? #4420
Description
Describe the query
I have a zephyr.ri image, obtained by building SOF with Zephyr.
This is loaded and booted and I have my sof card available:
root@imx8qmmek:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: btscoaudio [bt-sco-audio], device 0: 59040000.sai-bt-sco-pcm-wb bt-sco-pcm-wb-0 [59040000.sai-bt-sco-pcm-wb bt-sco-pcm-wb-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: sofwm8960audio [sof-wm8960-audio], device 0: Port0 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
root@imx8qmmek:~#
How can I use sof-logger to check the traces obtained in SOF?
What .ldc file can I use?
How can I obtained the .ldc file from SOF with Zephyr? Is it possible?
To Reproduce
I've tried reading the trace with the ldc file obtained from SOF with XTOS and I'm getting:
root@imx8qmmek:~# ./sof-logger -t -l /lib/firmware/imx/sof-gcc/sof-imx8.ldc 2>&1 | tee trace.txt
error: src hash value from version file (0x0) differ from src hash version saved in dictionary (0x2fd09907).
root@imx8qmmek:~# ./sof-logger -l /lib/firmware/imx/sof-gcc/sof-imx8.ldc 2>&1 | tee trace.txt
error: Unable to open in file /sys/kernel/debug/sof/etrace: No such file or directory

I'm working on this, will hopefully submit something working this week. Related:
Add new mtrace_printf() and use it for DMA init error handling and demoting banner to INFO level #4389
Restore early tracing #4334
ipc_send_queued_msg() has a hard dependency on the EDF scheduler #4356
Also take note of
[BUG]Empty or stuck DMA trace - Initial FW ABI banner message not found in logger.data.txt #4333

Sorry forgot to mention that there is a partial solution that already works: zephyrproject-rtos/zephyr#35186
At least it works for Intel hardware, dunno about IMX sorry.

Thanks, @marc-hb!
For now, I'll try the partial solution, see if it works for i.MX.

BTW you'll need to revert 4e8743f
zephyr: imx: split initializationthat just got merged in #4217 . I'm curious why you needed that, maybe it was just a copy/paste of cavs commit cf8e35f? I submitted a revert of the latter in #4452iuliana-prodan commentedon Jul 8, 2021
@marc-hb I've tried you're commits from #4452 and I've reverted mine - here's the commit from my branch, but now I cannot load the topology:
Is this working on Intel's platforms with Zephyr?
On i.MX, without enabling dma trace, so without this commit, I can load the topology and have my sof audio card:
Am I forgetting something?

@iuliana-prodan first a disclaimer: I'm not claiming the DMA trace is ready for prime time, not even with #4452 . This being said, I do not observe any or the errors you posted. I have "other problems" :-)
In general I think a good rule of thumb is to ignore all errors past the first one. So I would first look into the sof_ext_man and ABI warnings - unless of course you know exactly what they mean.
Then the
error: ipc timed out for 0x90030000 size 80seems interesting, it looks a bit like #4428. Strange.marc-hb commentedon Jul 8, 2021
Forgot this sorry: we are seeing scheduling issues and IPC timeouts in Zephyr even without enabling the DMA trace. So it could also be just the messenger.
If you don't absolutely need it right now then I would recommend not trying it yet.

More specifically:
After reverting these two locally I think I'm back on track.
marc-hb commentedon Jul 16, 2021
A few rough edges and not reviewed yet but PR #4503 works4me if you want to give it a try. Tested only with a revert of #4377 for now.

Mostly works now
