Intel Arc 770 no video preview with Davinci Resolve Ubuntu 22.04 and linux Mint

[Daxtas]

  I have an 8GB AMD working with Ubuntu and Davinci, I wanted to upgrade to 16GB. When I installed the card and all the suggested drivers, Davinci Resolve opens but the videos are empty. I did a clean installation with Ubuntu and Linux Mint and I got nothing different. Will this issue be fixed or will I lose my money? I thought that if AMD works with Davinci without problems, Intel, integrated into the kernel, would not cause problems. It works perfectly with Blender, but not with Davinci.
Does anybody have an idea?

Hello Daxtas,

Thank you for posting on the Intel communities. I will be more than happy to help you. Since you are having issues with Davinci Resolve opening the videos but they are empty with your Intel® Arc™ A770 Graphics, to better understand the situation, please answer the following questions:

• Is the graphics card an Intel Branded Card or is it of another brand?
• To know your hardware and software information, download and attach the Intel® System Support Utility for the Linux* Operating System report, you can find the steps on the link Help Guide for the Intel® System Support Utility.

Hello Daxtas,

Were you able to run Intel® SSU to check your system environment? 

Let us know if you still need assistance.

Davinci Resolve needs some extension to the OpenCL driver which is currently not supported by the intel compute stack on linux.

It's not a limitation of the hardware but just of the software.

I have some experimental patches to add support for it and it works for my laptop (12th gen intel) but someone who tested it on Arc reported some issue with it. Not having an Arc GPU myself, I can't debug/fix it ...

What extensions is the OpenCL driver missing and what patches at them? I'm running into the same issue that OP is having but on Fedora.

[tnt]

The cl/gl sharing extensions.

They actually got merged upstream last week so they should make it into a release soon (anything newer than 24.09.xxx should have it).

If you build the `master` branch of intel-compute-runtime, it should work.

Thank you! I'm working through the compile errors now. Hope this works!

This might help : https://gitlab.com/lsde-stuff/intel-compute-runtime/-/tree/f39?ref_type=heads

Someone seems to have made a modified fedora package source with the patch included ...

(No idea how to use it, I'm not a fedora user but maybe you know ...)

Thank you! Based on what I read, it looks like this will fix my issue, however whether I'm compiling intel-compute-runtime or applying that patch to an RPM, I keep running out of memory before the compilation is done. I'm not really sure why either. I have 64 GB of RAM.

*sigh*

I'm gonna keep trying though.

[Myownfriend]

Sorry for being a pain but do you have any idea if it's important for built_ins to be compiled, too? That's what was causing the compilation issues that blew up memory usage. Skipping that step allowed it to complete but now when I import a video into Resolve, it causes Resolve to leak memory and previews still don't show up.

[tnt]

Not really sure what you mean by "built-ins" ... what command line did you use to build ?

[Myownfriend]

It looks like it has to do with building the kernels in shared/source/built_ins/kernels. The command I'm using to compile is from the .spec file from Fedora's intel-compute-runtime RPM.

cmake -DCMAKE_BUILD_TYPE=Release -DNEO_OCL_VERSION_MAJOR=%{neo_major}  -DNEO_OCL_VERSION_MINOR=%{neo_minor} -DNEO_VERSION_BUILD=%{neo_build} -DSKIP_UNIT_TESTS=1 -DNEO_DISABLE_LD_GOLD=1 -DKHRONOS_GL_HEADERS_DIR="/usr/include/GL/" -DKHRONOS_HEADERS_DIR="/usr/include/CL/" -DNEO_ENABLE_i915_PRELIM_DETECTION=1 -DCOMPILE_BUILT_INS=0 -DCL_TARGET_OPENCL_VERSION=300 -G Ninja

The .spec files are used by rpmbuild to make the RPM and I used Copr to offload the build process so I wouldn't have to worry about RAM usage. Even with Copr, the built_ins would not compile. The compilation would just get hung up 674 steps in eventually the subprocess would shut down and the compilation would fail.

Hello the developer https://github.com/smunaut have created a patch to add support for Intel GPUs or APUs to Davinci Resolve for Linux, the issue is that ARC gpus are not currently supported because he doesn't have a ARC GPU to debug and fix the issue, I have decide to create a donation page to collect money an buy a GPU for him, if someone want to cooperate with this fundraising visit the Donorbox page here: https://donorbox.org/arc-gpu-for-developer-of-davinci-resolve-linux-support-patch
