Bug in intel iGPU

[Asif2]

Unable to use Compute shader to calculate 2D FTs

code is available on https://bitbucket.org/asif_bahrainwala/csimage_2d_ft/src

you will need to read the README file

change SIZEX and SIZEY from 100 to 400:

#define SIZEX 400ul
#define SIZEY 400ul

Environment:

 device:Intel(R) UHD Graphics 630 (CFL GT2) $$ 16027 $$ 1

Ubuntu 22.04 (Linux 117LU22-AB2142 6.5.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Mar 12 10:22:43 UTC 2 x86_64 x86_64 x86_64 GNU/Linux)

To build, you will need qmake

qmake CSImage_2d_FFT.pro

This will generate your make file

This issue is also seen on our edge device using Pentium silver j5040

Please help me solve this.

This issue is not seen on Iris GPU.

Do keep in mind that this shader code is intensive and takes a lot of time to execute , I guess there is some timeout issue on the driver side.

As a work around, I am using a more optimized shader.

I did try to disable TDR:

I still get device lost issue
