Hi everyone,
I have some updates. I left the system idle most of the time during
the weekend and from time to time I played a video on youtube and
turned off the screen. Yesterday night I did the same and today
morning I checked the system and it got hung up during the night. This
time it took a
Hi Christian, Alexander,
I have enabled kmemleak, but memleak didn't detect anything special,
in fact this time, I don't know why, I didn't get any allocation
failure at all, but the GPU did hang after around 4h 6m of uptime with
Xorg.
The log can be found in attachment. I will try again to see
Hi Luis,
please enable kmemleak in your build and watch out for any suspicious
messages in the system log.
Regards,
Christian.

Hi Alexander,
I didn't notice improvements on this issue with that particular patch
applied. It still ends up failing to allocate kernel memory after a
few hours of uptime with Xorg.
I will try to upgrade to mesa 18.0.0-rc3 and to amd-staging-drm-next
head, to see if the issue still occurs with

Hi everyone,
I am getting a new issue with amdgpu with RX460, that is, now I can
play any videos with Kodi or play web videos with firefox and run
OpenGL applications without running into any issues, however after
some uptime with XOrg even when almost inactive I get a kmalloc
allocation failure,
Fixed with this patch:

I've tested the kernel from amd-drm-next-4.17-wip at commit

In this case please open a bug report on fdo and describe exactly how to
reproduce it.
Marek should be able to take a look then.
Thanks,

David, replying to your question... The issue is indeed reproducible
on x86, I just did it with kodi and the same VP9 video. So it is not
arm specific.

Hi Luis,
In general please add information like /proc/iomem and dmesg as
attachment and not mangled inside the mail.
The good news is that your ARM board at least has a memory layout which
should work in theory. So at least one problem rules out.
I don't think that apitrace would be much
Just a small update, regarding to what I have posted...
I've made additional tests with mesa-17.4 at commit "radv: Implement
binning on GFX9" - 6a36bfc64d2096aa338958c4605f5fc6372c07b8 and I was
able to gather a smaller apitrace of kodi playing a video with about
1GB that hangs the GPU, almost
Ok... I've done some of the suggested tests.
I still haven't tested on x86, but I'll get to that.
I've recompiled the kernel to disable Power Management as much as
possible at all levels, including the PCIe, I've also modified
/include/drm/drm_cache.h - static inline bool
when you refer to API traces, you're suggesting to strace
kodi, or what do you mean?
What I meant was apitrace (https://github.com/apitrace/apitrace), but
when even the lightdm login screen crashes than this won't be much helpful.
That strongly sounds like a ARM specific problem, maybe USWC
Dear Mr. David, Mr. Christian,
First of all, thanks for your replies!
David, I will try the same software versions on x86 to see if I am
able to replicate the problem on x86, but I suspect it is ARM
specific... I'll report back when I have more details.
Christian, I'll collect the data you've
Hi Luis,
well first of all that isn't a deadlock, but just a hardware lockup. So
the traces and logs you tried to attach are not really useful.
What we need instead is a full dmesg and/or some kodi logs, API trace
etc.. what exactly is happening when the problem occurs.
Please also try
Did you try it on x86 board? Is there same issue?
We should identify it is ARM specific or genera issue for amdgpu driver.
Thanks,
David Zhou
