1.7.426 mask select stars not working

[alacant]

Hi Ivo, everyone
StarTools-Linux64-GPU opencl via beignet on lubuntu 20.04

mask - auto - stars produces the attached image.
similar result (only part of the image selected) with turning off tracking Track - grain removal

beignet error:
Beignet: "Exec event 0xfc0e50 error, type is 4592 (repeated hundreds of times).

auto star mask working ok for me using windows flavours.

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.
Image size 2571 x 1804

Cheers

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

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!

[admin]

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