Re: Deadlocks with multiple applications on AMD RX 460 and RX 550 - Update 2

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 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,

Hi everyone, I've tested the kernel from amd-drm-next-4.17-wip at commit 9ab2894122275a6d636bb2654a157e88a0f7b9e2 ( drm/amdgpu: set DRIVER_ATOMIC flag early) on ARMv7l, and the reported issues seem now to have gone. I haven't checked from which commit this is fixed, but it is now fixed! I also

Hi Michel, Christian, Michel, I have tested amd-staging-drm-next at commit "drm/amdgpu/gfx9: only init the apertures used by KGD (v2)" - 0e4946409d11913523d30bc4830d10b388438c7a and the issues remain, both on ARMv7 and on x86 amd64. Christian, in fact if I replay the apitraces obtained on the

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

Re: Deadlocks with multiple applications on AMD RX 460 and RX 550 - Update 2

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

Re: Deadlocks with multiple applications on AMD RX 460 and RX 550 - Update 2

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
