It ran OK, but only when I switched from my X11 session to console, or if I= run it as root. Being inside X, it reports: > radeon: Failed to get PCI ID, error number -13 > Using platform: Clover > No devices found. Check OpenCL installation! devel/clinfo also behaves this way (finds no devices) and spits out the same error. My user belongs to "video" group, and permissions on /dev/dri/* are sane (default, "rw-" for "video" group). -13 indicates "permission denied" (-EACCES). Apparently, similar (or perha= ps related) bug was discovered and fixed in Mesa back in 2012 [3]. The code in current Mesa is different though. Perhaps FreeBSD needs special treatment,= or original bug resurfaced. I'm not an expert on Mesa codebase but will gladly provide any additional details and happy to test patches.
