Blender support for AMD HIP on Windows

Building Blender
1

Hello Team,

I have built blender using Visual Studio 2019 and I have found that the blender.exe has issues because there is no support for ROCm on Windows as per the following website link:
https://wiki.blender.org/wiki/Building_Blender/GPU_Binaries
But the ROCm devices work properly using Blender exe downloaded from official website.

It looks like the blender source code is NOT equivalent to the downloadable executable provided at official blender website given above

I would like to have the setting which need to be done while building blender source code so that it will have HIP section enabled in /EDIT–>Preferences–> System and AMD ROCM supported devices can be listed for ROCm on Windows.Currently if I build blender and open blender.exe generated after build, then on clicking HIP section in Edit ->Preferences->system the application crashes.
Please help me how to build blender for getting AMD GPU binaries for ROCm.

thanks,
Raj

I don’t know anything, but I had seen this before.

@Raj,

In order to have the Hip kernels compile you need to install a HIP compiler. When blender build script doesn’t detect a HIP compiler it will disable compilation of it. If you have it installed and the option turned on it will compile the kernels.

Please check the documentation provided in our wiki Building Blender/Windows - Blender Developer Wiki last section refers to Building Blender/GPU Binaries - Blender Developer Wiki .

If your doing actual development it is adviced to disable kernel builds as they can take a long time.

The HIP SDK for building AMD GPU binaries is not currently publicly available, we hope this will be released soon.

It seems the Windows version of HIP SDK is still only available to blender’s build server.

Can you please publish if/when the HIP SDK for AMD GPU becomes publicly available on Windows?
I know I should look for this on AMD, but their care for customers on the GPU front is only second to Google’s starting and killing stuff. This is partly explained by Linux being the more common platform for using AMD GPU as single/double precision accelator, but I hope you guys at Blender might be the first to know and perhaps push a bit.
Thanks in advance!

Only AMD can provide accurate information on this. If the Blender/Cycles developers did know when the HIP SDK would be made publicly available on Windows, they would most likely be unable to share that information until after AMD made their own announcement about it.

Hi There. I don’t have an exact date, but I’m told very soon. (Hopefully next month or so)
