description
on ADLP_RVP_SDW and ADLP_RVP_HDA check-sof-logger failed with logger.error showing "error: Unable to open version file /sys/kernel/debug/sof/fw_version: No such file or directory" which may indicate slow/incomplete firmware boot.

And this failure leads to two FAIL/TIMEOUT in following 2 testcases , eg.
when check-alsabat-headset-playback

ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card
aplay: main:830: audio open error: No such device

when check playback all formats

2021-07-13 21:26:34 UTC [REMOTE_INFO] No SOF sound card found, exporting pipeline parameters from proc file system
error: Unable to open version file /sys/kernel/debug/sof/fw_version: No such file or directory

Something weird is long time to get suspend after ,check-sof-logger failed
after executing check-sof-logger , I got a 'fail' and then I tried 'cat /sys/bus/pci/devices/0000:00:1f.3/power/runtime_status' over and over again .
I got 'active' and then eventually got 'suspend' at the time which is actually 50 seconds after check-sof-logger failed. (You can see a 50 seconds' gap in the following picture)
image

I think after check-sof-logger testcase failed , there should be nothing using audio ,right ? So taking so much time to get suspend looks weird (However I am not quite sure whether this has something to do with 'no SOF sound card found' log in check-playback-all-formats testcase)

    BTW , reloading driver in check-sof-logger.sh is for getting logs from BYT ,right? For those platforms which can provide wanted logs, we can skip driver reloading maybe .

    This bug should be related to the i915 probe taking a long time.

    @marc-hb hi marc , let's discuss about it here .
    Since check the non-stale logs as well as restarting the firmware is necessary , shall we give ADLP_RVP_SDW / ADLP_RVP_HDA more time to complete the firmware boot?
    These two platforms can reboot firmware successfully , they just need more time

    Thanks, I renamed this bug.

    Since check the non-stale logs as well as restarting the firmware is necessary , shall we give ADLP_RVP_SDW / ADLP_RVP_HDA more time to complete the firmware boot?

    I'm just going to temporarily skip the check-sof-logger test on these systems, it will be more visible with less risk to forget to restore the test later.

    In 5288?model=ADLP_RVP_HDA&testcase=check-sof-logger the same test passed! This was on 2021-07-15 02:10:50 UTC and sh-adlp-rvp-hda-01.sh.intel.com at with SOF commit 0fa9f7d and linux kernel commit 9b277b8

    In the 9 minutes older 5285?model=ADLP_RVP_HDA&testcase=check-sof-logger it failed as described above and sh-adlp-rvp-hda-02.sh.intel.com and on sh-adlp-rvp-sdw-03 with the SAME SOF commit 0fa9f7d and kernel commit 9b277b8!

    In the same runs the test passed on other systems like sh-adlp-rvp-nocodec-02 (5285) or sh-adls-rvp-hda-04 (5285) or sh-adls-rvp-hda-05 (5288)

    EDIT: more failure examples listed in (unrelated) thesofproject/sof#4333

    This bug should be related to the i915 probe taking a long time.

    Does this happen randomly? Or is it happening only on certain units? @plbossart , Is it possible to see this long probe time in journalctl -b and if yes how?

    I'm just going to temporarily skip the check-sof-logger test on these systems, it will be more visible with less risk to forget to restore the test later.

    I submitted this in thesofproject/sof-test#741 but I'm closing it because if this bug is intermittent then we first want to know how frequent it is.

    @marc-hb The only indication that the probe workqueue finished is this dynamic debug log:

    dev_dbg(dev, "Completing SOF PCI probe");

    Thanks @plbossart. I took a closer look at the logs on sh-adlp-rvp-hda-02 and it does look indeed like an intermittent, display related issue. I'm copying two extracts from the logs below. The first one is from a successful firmware load, the second log is when the firmware failed to fully load and this happened only minutes later on the same system without any reboot in between.

    Note there are other, earlier differences before the Completing SOF PCI probe message. Any insight?

    Successful log

    any idea what this is @marc-hb ?

    This seems to come even before the card is created?

    Not sure in this particular case but in general this is just systemd monitoring /proc/asound/cards for dependency tracking purposes: other services may require a soundcard - like pulseaudio for instance. Even when disabling pulseaudio systemd still keeps track.

    Very easy to see it for yourself:

    sof-test/tools/kmod/sof_insert.sh
journalctl -f # in a different terminal
Jul 15 16:17:44 up2 systemd[1]: Reached target Sound Card.

sof-test/tools/kmod/sof_remove.sh
Jul 15 16:18:05 up2 systemd[527]: Stopped target Sound Card.

systemctl show sound.target

 => FragmentPath=/lib/systemd/system/sound.target

man systemd.special

       sound.target
           This target is started automatically as soon as a sound card is plugged in or becomes available at boot.

           This may be used to pull in audio management daemons dynamically when audio hardware is found.

    @kv2019i @marc-hb @libinyang
    Adding new PCI IDs manually to i915.force_probe has been a regular step on any bleeding edge platform (otherwise i915 refuses to load on these)

    On ADL DUTs , add following contents can help.

    cat /etc/modprobe.d/i915.conf  (if there is no i915.conf , add it by yourself)
options i915 force_probe=*

    I have modified i915.conf on all ADLP_RVP_SDW ADLP_RVP_HDA DUTs, they all pass check-sof-logger testcase now.

    @kv2019i can you confirm that i915.force_probe is helpful only when i915 REFUSES to load AT ALL? Not when it is flaky like here.

    I have modified i915.conf on all ADLP_RVP_SDW ADLP_RVP_HDA DUTs, they all pass check-sof-logger testcase now.

    This test was failing only from time to time, so maybe you just got lucky.

    Yes so I will track how they perform in daily tests

    @marc-hb Correct, on platforms where i915.force_probe is needed, driver probe will fail every time if the setting is not set.

    It is possible the i915 negotiation failed earlier on some occasions (but i915 was still not functional), but definitely now with recent upstream merge and the force_probe setting, expecation is that at least i915 is no longer causing delays to the probe.

    Thanks @kv2019i!
    @XiaoyunWu6666, at your leisure please remove the i915.force_probe you just added. I don't think they can cause any harm but they can cause confusion.

    @marc-hb @XiaoyunWu6666 no, please keep the i915.force_probe . It's still needed. i915 won't load on new platforms without this option.

    i915 won't load on new platforms without this option.

    @XiaoyunWu6666 changed it only on systems where i915 was already loading.

    FYI, I changed that on ADLP_RVP_SDW and ADLP_RVP_HDA DUTs.
    in inner daily-ADL 5495 5635 they worked well(ADL models have been added back to daily testplan)

    HDMI1 worked well on ADLP_RVP_SDW (-Dhw:0,5 )and ADLP_RVP_HDA(-Dhw:0,3) with latest sof-dev and /etc/modprobe.d/i915.conf

    options i915 force_probe=*

    hi , @kv2019i , shall we close this ? :) thanks
