[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
Since beginning of September the bug disappeared for me. I'm not sure what update caused it but the usual suspects are: linux- image-5.4.0-45-generic:amd64 (5.4.0-45.49~18.04.2, automatic) with its kernel module amdgpu.ko or some xorg-...-hwe parts or a combination of them. But I tried with a boot of a kernel 5.3.0-40 and the bug emerged again. So it is more likely that it was a kernel related problem. I have to note that I removed the line with "EnablePageFlip" within the configuration file "/usr/share/X11/xorg.conf.d/10-amdgpu.conf" of my suggested workaround #54 like this: Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" EndSection -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwin/+bug/1849084/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
For all who used the workaround #61: The current update xserver-xorg- video-amdgpu-hwe-18.04:amd64 19.0.1-1ubuntu1~18.04.1 19.1.0-1~18.04.1 overwrites the file /usr/lib/xorg/modules/drivers/amdgpu_drv.so (file date May 21 09:16) and the bug returns again. It is one step forward one step back ...

I can confirm that #61 removes the bug. I'm running Kubuntu 18.04 with a hwe kernel 5.3.0-51-generic #44~18.04.2-Ubuntu. (Not 5.3.0-53 because it contains a power off bug.) Great!

[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
@jose: The above workaround seems to be related with your patch mentioned at #42. The function "amdgpu_present_check_flip()" returns prematurely if the variable "info->allowPageFlip" is set to false. "info->allowPageFlip" contains the evaluation of the configuration "OPTION_PAGE_FLIP" evaluated from the option setting "EnablePageFlip". So the mentioned part of code where the patch is located is never processed.

[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
At least for me I found a reproducible workaround for the resume bug. I found it more or less with try and error. I added the option "EnablePageFlip" to the configuration file "/usr/share/X11/xorg.conf.d/10-amdgpu.conf" like this: Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" Option "EnablePageFlip" "off" EndSection and restarted. With this option set my computer always return from suspend. I do not really know about the impact of "EnablePageFlip" but I do not feel any significant degradation of video performance.

@Richard: I tried your suggestion without luck. The screen remains black, the backlight was switched on. To verify I tried multiple times. The only true workaround (with KDE) is to switch the compositor off before turning into sleep. You have to switch the compositor on after return from suspend. Somewhere I've found a systemctl script to manage this automatically, but I experienced the script's working not reliable. With KDE you have to press Shift-Alt-F12 to toggle manually the compositor's state.

I can confirm that with switched off compositor (KDE, Shift-ALT-F12) resume is working. But I think the compositor act as trigger only and is not the reason for the bug.

[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
P.B. I tried to verify your observation. Without luck. First I generated a Windows-10 bootable USB drive and managed to install and run the "AMD Driver Auto-detect tool". On Windows it was successful to set the computer into standby and resume. Then I've done a warm-start of the computer an booted into Linux. Now I was able to set the machine into standby and back to resume successfully. The next experiment was to do a power down reset and try the standby/resume with Linux again. It stopped with a blank black screen with backlight switched on. After a warm start (Alt-SysReq-B) all subsequent standby/resume cycles worked perfectly. My guess is that after a warm start some GPU register settings remain untouched causing success of the resume. Or in other words, the initial setup of the GPU is missing something which is done with the first (unsuccessful) standby/resume after power up. My ubuntu kernel version is meanwhile 5.3.0-46-generic. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwin/+bug/1849084/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
This is a very interesting observation! In one of my previous posts I described the fact that after the first unsuccessful resume and a following soft-reset with Alt+SysReq+B all subsequent resumes will succeed. My guess was that there was something changed in the GPU's hardware registers before or after the first resume. It cannot be any software influence since the software started again. After a cold reset the game starts again. My assumption was that the GPU's hardware register change was volatile. Maybe the "AMD Driver Auto-detect tool" stores this one time change non- volatile in any kind of configuration storage element within the GPU. Then it behaves the same like you described. Currently I do not know of any dual use of drivers between Linux and Windows, but to have a built- in non-volatile configuration storage supporting the GPU is very likely. Unfortunately I do not have a dual boot machine. I'm running only Linux. So I'll try to create a USB-stick based Windows 10 to verify your experience. It will take some time.

[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
Sorry, I made a mistake I'm running kubuntu (not Ubuntu like mentioned in #24). Indeed I can confirm that with a switched off compositor resume will work. And I can confirm that resume only fails the first time after a power up reset of the computer. When the screen turn blank after the first time resume I do a login via SSH and initiate a reboot. After this all suspend / resume cycles will work perfectly. It is strange that a compositor's bug will affect the amdgpu driver module. This snippet of journalctl log shows a line emitted by the amdgpu module where a test runs into a timeout: Feb 27 10:43:02 Lin kernel: PM: suspend exit Feb 27 10:43:02 Lin systemd-sleep[2125]: System resumed.

[Ubuntu-x-swat] [Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver
Back to freeze on resume. I'm running Ubuntu 18.04.4 LTS on a Lenovo Desktop V530-15ARR with AMD Ryzen 5 2400G with Vega 11 Graphics and a kernel 5.3.0-28-generic. With a kernel 5.0.0-29 suspend and resume were perfect (from the users point of view). But I had sometimes graphic freezes during normal usage like browsing. So I upgraded the kernel to 5.3.0-28. This kernel shows suspend and resume problems. I think I've found a workaround for the failing suspend described at https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1851054 . But now resume sometimes traps into a black screen. It seems that only the first resume after a cold start fails. When resume fail I'm able to login via SSH and to initiate a reboot. Subsequent suspend and resumes do survive. Since I've repeated only a few times the same experiment I'm not 100% sure about this.
