Unable to get xmrig to use GPU ... missing drivers or libs? [SOLVED]

I would like to run a GPU bench using xmrig but am unable to get it to use the GPU. It seems that OPENCL is disabled:

% xmrig --bench=1M --opencl --no-cpu
 * ABOUT        XMRig/6.24.0 gcc/15.1.1 (built for Linux x86-64, 64 bit)
 * LIBS         libuv/1.51.0 OpenSSL/3.5.0 hwloc/2.12.1
 * HUGE PAGES   supported
 * 1GB PAGES    disabled
 * CPU          AMD Ryzen 9 9950X 16-Core Processor (1) 64-bit AES
                L2:16.0 MB L3:64.0 MB 16C/32T NUMA:1

I have the following opencl packages installed, what could be missing that would prevent the benchmark on the GPU?

% for i in opencl amd; do pacman -Qs $i ; done
local/clinfo 3.0.23.01.25-1
    Simple OpenCL application that enumerates all available platform and device properties
local/libclc 20.1.6-1
    Library requirements of the OpenCL C programming language
local/ocl-icd 2.3.3-1
    OpenCL ICD Bindings
local/opencl-headers 2:2024.10.24-1
    OpenCL (Open Computing Language) header files
local/opencl-mesa 1:25.1.4-1
    Open-source OpenCL drivers
local/rocm-opencl-runtime 6.4.1-1
    OpenCL implementation for AMD

    Microcode update image for AMD CPUs
local/comgr 6.4.1-1
    AMDGPU GPU Code Object Manager
local/linux-firmware-amdgpu 20250627-1
    Firmware files for Linux - Firmware for AMD Radeon GPUs
local/rocm-core 6.4.1-1
    AMD ROCm core package (version files)
local/rocm-device-libs 6.4.1-1
    AMD specific device-side language runtime libraries

    OpenCL implementation for AMD
local/xf86-video-amdgpu 23.0.0-2 (xorg-drivers)
    X.org amdgpu video driver

EDIT: Ah, my mistake was using --bench which I guess configures opencl blockage.
