Hi Ivo, everyone

similar result (only part of the image selected) with turning off tracking Track - grain removal

Hmmm...
If this is a case of the load being to much for the iGPU to handle before the driver triggers a timeout, I just release a new version 1.7.427 that may help with this in some edge cases. I'm worried Beignet still isn't playing ball.

How big was the image (X * Y resolution)?

Thank you,

Hi
Same mask error with 427 but no beignet messages.

I was just able to replicate this on an i5 5300U, also running Beignet. The kernel ring buffer (dmesg) showed this;

[ 3402.936844] [drm] stuck on render ring
[ 3402.937147] [drm] GPU HANG: ecode 8:0:0x8ed1fff2, in StarTools-Linux [8232], reason: Ring hung, action: reset
[ 3402.937149] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 3402.937150] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 3402.937151] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 3402.937152] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[ 3402.937153] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 3402.939322] drm/i915: Resetting chip after gpu hang
[ 3414.937655] [drm] stuck on render ring
[ 3414.938016] [drm] GPU HANG: ecode 8:0:0x8ed9fff2, in StarTools-Linux [8250], reason: Ring hung, action: reset
[ 3414.940179] drm/i915: Resetting chip after gpu hang

I can replicate this if I really stress the system, playing a YouTube video in tandem with processing in StarTools.

Googling this problem seem to point to issues with the Intel drivers in newer Linux kernels.

Does your dmesg show something similar?

Also, I have been reading that changing acceleration method from SNA to UXA is supposed to help....

changing acceleration method from SNA to UXA
How would I do that?

I've had to go back to non GPU for the current session but I'll get the dmesg from the GPU version.

It's a Xorg.conf setting

This should be achievable by creating a file named 20-intel.conf in /usr/share/X11/xorg.conf.d/ (for us Linux Mint / Ubuntu users)

In it, you will want to put;

Code: Select all

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"  "uxa"
EndSection
Afterwards you should no longer see any mention of SNA being used when doing;

Code: Select all

cat /var/log/Xorg.0.log | grep 'intel'

I just processed a 2283x1685 image successfully with those changes on the i5-5300U's iGPU, but as it seems to be an issue with flaky drivers, I can't guarantee that switching to UXA stabilises them without more rigorous testing...

Do let me know if this works for you!

Another update; after some more testing on the i5-5300U, I'm definitely seeing a marked improvement in iGPU stability. This is looking promising!
