OpenCL v>=1.2 on amd radeon rx460/debian stretch (inst/cfg)

Postby khelair » 2017-07-19 21:57

I upgraded to stretch in order to locate more up-to-date libraries for an OpenCL version >= 1.2 that will work with my AMD Radeon RX460 for GPU computing. Although I have the correct x server installed, configured, and confirmed video acceleration working, I have yet to find (or configure correctly) an OpenCL other than 1.1.

Current clinfo output reports 0 platforms, though I've tried reinstalling everything applicable via a search for 'opencl' from synaptic. I'm afraid I'm a bit of a neophyte when it comes to working with GPU computing/OpenCL applications. I don't really know what other sources of system information/package install logs or anything to include that might be useful here. Please let me know if I should be including anything else.

I desperately wish to be utilizing the GPU for things, though, and I really hate having to constantly reboot to Doze7 (dual boot, obviously) in order to keep the GPU utilized when I'm not actively doing anything requiring linux. Did I mention I hate 'doze? Regardless, this is a highly sub-optimal situation for me. I would be very grateful for any assistance that may be offered. Thanks in advance for help & pointers in the right direction!

Re: OpenCL v>=1.2 on amd radeon rx460/debian stretch (inst/c

Postby khelair » 2017-10-22 03:53

I don't mean to pointlessly bump, but is there seriously still no OpenCL v1.2+ available for the AMD Radeon rx460 and friends? :cry:
