@Nightbane112 It sort of works but very unstable. Obviously, every time I need an app to use OpenCL I must launch it from a terminal to make OpenCL "sort of work"

In blender, it takes 3 tries before it stats to render but it is ridiculously slow (like CPU is several times faster. If you try to hit render again, blender will crash.

On Resolve thumbnail previews are completely useless, playback and render does work, however when using power windows resolve crashes.

Still very buggy. I think it is because of the experimental SI support. I wish I didn't have to launch every app via terminal.

@Olympus593 From the looks of it, I don't think its a driver problem. A bit of searching online lead me to this issue on GitHub (

How about appending this to your bashrc file and see if it changes anything?

export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=100

@Nightbane112 I am using the amdgpu kernel driver and I have already enabled experimental support (I already double checked to make sure that the driver does load) but every time I try to use OpenCL (for example Blender Cycles Render) it ends with Error -6 CL_OUT_OF_HOST_MEMORY. Same error with DaVinci Resolve.

@Olympus593 Are you using the amdgpu kernel driver? You can try using the experimental support for your GPU series (

From the official amdgpu-pro driver page (, I could see your GPU is supported but you might need to cross-check on the AMD forums.

Do I need to downgrade Xorg or do some configuration because mine always ends up with Error -6 in any app trying to use OpenCL. I have a GCN 1 card with support provided by the AMDGPU driver.

PSA : I remove my previous comment to avoid confusion as now that this package works with the current version (opencl-amd 18.3.641594).

@stoostranger Haha, seems like this package finally works although still needs the libdrm downgrade shenanigans. Thanks!

I tried downgrading without libdrm and lib32-libdrm downgrade but blender still segfault. then I downgrade libdrm to 2.4.93-1, then install opencl-amd 18.3.641594 again, then now Blender Circle renderer works perfectly. Hope this help

As some of you noticed 18.30.641594-1 does not seem to work with blender. Manual downgrading worked for me. Edit PKGBUILD to match the following values:



also change amdgpu1_2.4.92 to amdgpu1_2.4.91 and as @Nightbane112 mentioned downgrade libdrm and lib32-libdrm to 2.4.93-1

I have same error too on Blender (portable, Manjaro), the only temporary solution I found is, in Blender folder run "blender-softwaregl" file, it uses software and is very slow depend on your system. then I can render with Opencl. I hope it gets sooner fixed.

@IMBJR I am getting roughly the same issue as you when this package is installed.
