RUNTIME_PM_BLACKLIST doesn't work on ThunderBolt3 dock

[plumlis]

Describe the bug

My usb soundcard have some poping noise when using on thunderbolt3 dock.
And I found there is a device called 00:16.0 is set to battery saved.
I changed it to "bad" in Powertop so problem sloved

Expected behavior

I add this devices( 00:16.0 ) to RUNTIME_PM_BLACKLIST and it seems doesn't work on Thunderblot3 dock device.

To Reproduce

Steps to reproduce the unexpected behavior:

1. add a thunderbolt3 dock connected device to RUNTIME_PM_BLACKLIST
2. connect laptop to thunderbolt3 dock
3. check powetop
4. found this device still in battery save mode

here is my tlp-stat

The actual expected result when blacklisting a device isn't that the device (magically) works, but rather that power saving gets disabled, which is obviously the case (control=on means disabled, control=auto means enabled):

/sys/bus/pci/devices/0000:00:16.0/power/control = on (0x078000, Communication controller, mei_me)

However, the whole blacklisting is redundant, because TLP will set control=on for all PCIe devices on AC power anyway, it's the default config:

/etc/tlp.conf L0302: RUNTIME_PM_ON_AC="on"

What i do not understand at all is what the intel management engine (driver mei_me) has to do with the problem.

EDIT: your USB sound card(s) are blacklisted already (implicitly because of the usbhid driver):

Bus 005 Device 003 ID 0b05:183c control = on, autosuspend_delay_ms = 2000 -- ASUSTek Computer, Inc. Xonar U7 MKII (snd-usb-audio, usbhid)
Bus 003 Device 002 ID 17ef:306a control = on, autosuspend_delay_ms = 2000 -- Lenovo ThinkPad Thunderbolt 3 Dock USB Audio (snd-usb-audio, usbhid)

Please be so kind and post long outputs via https://gist.github.com/ (as requested in the bug report template). Thanks for your understanding

[plumlis]

Sorry for the long outputs.

I know that RUNTIME_PM_ON_AC="on" is default setting and it shoud be work for all PCIe devices.

But actually it doesn't work on thunderbolt dock devices.

You can see the "good" parts PCI devices, they are all about thunderblot3 dock.

no matter I tried tlp ac / tlp bat they are still on "Good". It seems TLP doesn't work on this.

[linrunner]

Powertop can generate an html report, you may view it in a browser too:

sudo powertop -r report.html

I suggest your create two reports:

1. The exact state TLP produces on boot
2. With your manual change(s) to solve the audio problem

Attach the results as files.

[plumlis]

Here are the reports.

powertop.zip

with tlp naming is The exact state TLP produces on boot

another one is with manual change to solve the audio problem.

[linrunner]

OK, the difference is as expected after setting the device to "bad" manually:

echo 'auto' > '/sys/bus/pci/devices/0000:00:16.0/power/control';

The question is why the blacklisting fails for both driver and device.

Please provide a trace for boot an AC power – via https://gist.github.com/ please.

[plumlis]

Thanks for your reply
Here is my logfile

https://gist.github.com/plumlis/8c4fb5197e38607542b8f5eb7e4e549e

[linrunner]

So for your test case blacklisting works as designed. The device address based rule acts and no change is applied:

AC > BAT

21:11:38 plum-laptop tlp[13593]: set_runtime_pm(1).bloack_address: /sys/bus/pci/devices/0000:00:16.0 [0x078000]

Compare with the other log entries with 'rc=0', where TLP actually writes to control (successful).

[linrunner]

But i asked you for the trace of a different test case i.e. booting on AC power. Can you provide that trace too?

[plumlis]

Thank you for your reply.

Here are more logfiles

Both of them don't change the status of device 0000:00:16.0, Still "Good" in Powertop.

[linrunner]

Both of your boot test cases hit a blacklist:

1. [Blacklist on] Device in RUNTIME_PM_DRIVER

14 21:26:35 plum-laptop tlp[1871]: set_runtime_pm(0).bloack_address: /sys/bus/pci/devices/0000:00:16.0 [0x078000]

2. [Remove Blacklist] But device driver mei_me still in RUNTIME_PM_DRIVER_BLACKLIST

14 21:34:50 plum-laptop tlp[1366]: set_runtime_pm(0).black_driver: /sys/bus/pci/devices/0000:00:16.0 [0x078000]

Conclusion: auto is in fact the kernel driver default and blacklisting just preserves it (works as designed).

Next step: remove mei_me from RUNTIME_PM_DRIVER_BLACKLIST, reboot and provide trace.

Actually I haven't enable RUNTIME_PM_DRIVER_BLACKLIST before
So I made these logs

With default RUNTIME_PM_DRIVER_BLACKLIST enabled ,"mei_me" included.
https://gist.github.com/plumlis/570bc3a167cc5edcd3a4bf7f6d04a7ec

RUNTIME_PM_DRIVER_BLACKLIST enabled, without "mei_me"
https://gist.github.com/plumlis/bcc91b06910d7ecea7e6e68c2c1c34f2

Finally, With

RUNTIME_PM_DRIVER_BLACKLIST="amdgpu nouveau nvidia pcieport radeon"

and devices/0000:00:16.0 is set to "Bad" in Powertop.

Very well. If you consider this solved now, feel free to close.

Actually I haven't enable RUNTIME_PM_DRIVER_BLACKLIST before

Of course, but it's enabled by default and mei_me was added as a workaround for shutdown hangs. The line must be uncommented and changed to deviate from the intrinsic default. I know it's a bit unintuitive ...

Thank you for your help.
Issue sloved.
