            Bug ID: 106447
           Summary: System freeze after resuming from suspend (amdgpu)
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: kugel@rockbox.org

Similar to #104649 but happening on amdgpu.

The system immediately locks up when resuming from suspend. I get to see the
mouse cursor and the blue background of KDE's screen lock (but no password
entry or anything like that), but cannot do anything.

I can also reproduce on 4.16.7 and 4.17-rc4. This does not happen with amdgpu
blacklisted, or with Arch Linux' LTS kernel (4.14.39) though I get other random
failures on the LTS kernel.

Unfortunately, the systemd journal does not contain anything after entering
suspend so I have no possibility to get at a backtrace.

System:
Arch Linux w/ Linux 4.16.7
DMI: HP ZBook 14u G5/83B2, BIOS Q78 Ver. 01.00.05 01/25/2018
Intel Kaby Refresh 8550u

Generation)

commit 08810a4119aaebf6318f209ec5dd9828e969cba4
Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Date:   Wed Oct 25 14:12:29 2017 +0200

    PM / core: Add NEVER_SKIP and SMART_PREPARE driver flags

    The motivation for this change is to provide a way to work around
    a problem with the direct-complete mechanism used for avoiding
    system suspend/resume handling for devices in runtime suspend.

    The problem is that some middle layer code (the PCI bus type and
    the ACPI PM domain in particular) returns positive values from its
    system suspend ->prepare callbacks regardless of whether the driver's
    ->prepare returns a positive value or 0, which effectively prevents
    drivers from being able to control the direct-complete feature.
    Some drivers need that control, however, and the PCI bus type has
    grown its own flag to deal with this issue, but since it is not
    limited to PCI, it is better to address it by adding driver flags at
    the core level.

    To that end, add a driver_flags field to struct dev_pm_info for flags
    that can be set by device drivers at the probe time to inform the PM
    core and/or bus types, PM domains and so on on the capabilities and/or
    preferences of device drivers.  Also add two static inline helpers
    for setting that field and testing it against a given set of flags
    and make the driver core clear it automatically on driver remove
    and probe failures.

    Define and document two PM driver flags related to the direct-
    complete feature: NEVER_SKIP and SMART_PREPARE that can be used,
    respectively, to indicate to the PM core that the direct-complete
    mechanism should never be used for the device and to inform the
    middle layer code (bus types, PM domains etc) that it can only
    request the PM core to use the direct-complete mechanism for
    the device (by returning a positive value from its ->prepare
    callback) if it also has been requested by the driver.

    While at it, make the core check pm_runtime_suspended() when
    setting power.direct_complete so that it doesn't need to be
    checked by ->prepare callbacks.

(I haven't tried reverting just this on top of 4.16 yet).

Interestingly, this commit seems to also affect my wifi. I.e. the good commits
(from the susped pov) do not have working wifi, while bad commits have working
wifi.

I'll attach a dmesg output when running on the last good commit

I can suspend+resume just fine with amdgpu blacklisted, so I'm under the

That's debatable, given you bisected to a non-amdgpu commit, which affects WiFi

I'll report the bug on the other site as well. 

In my view: Loading the amdgpu module breaks resuming from suspend. Maybe the
module isn't correctly adapted to the changes made in generic subsystems
earlier.

--- Comment #15 from Thomas Martitz <kugel@rockbox.org> ---
I investigated the commit found by git bisect a bit more, and found that the
following patch (which reverts part of said commit) repairs resuming.

I can't tell the consequences, however reading the commit message suggests this
part is non-critical:

> While at it, make the core check pm_runtime_suspended() when
> setting power.direct_complete so that it doesn't need to be
> checked by ->prepare callbacks.

PM_EVENT_SUSPEND;
        spin_unlock_irq(&dev->power.lock);
        return 0;
 }

So, what to do with this information / potential fix?

[Bug 106447] System freeze after resuming from suspend (amdgpu)

Hello ,

i don't know if this is the correct place to state this,
but i have a Desktop PC running 

Ubuntu 16.04 

and i noticed too that the system won't resume from suspend after installation
of 

amdgpu-driver of rx560


this happens with the AMD Driver for 16.04 Xenial

https://www.amd.com/en/support/kb/release-notes/rn-prorad-lin-amdgpupro


but also with the AMDGPU.PRO driver for 18.04

https://www.amd.com/pl/support/1881



I have to say that i use Kubuntu instead of Ubuntu.

 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64
x86_64 x86_64 GNU/Linux


The System is

Ryzen 5 2600
AMD RX560 2GB
16 GB RAM.



Withouth the AMDGPU Driver there is no problem with suspend as it seems.
