 Posted: Thu Jun 04, 2020 4:40 pm Post subject: OpenCL on older Radeon (Redwood)? |
 |
|
I've been poking around for a bit trying to see whether I can get OpenCL from the stock Gentoo repo (no overlays) to work on my older Radeon (Redwood PRO - Radeon HD 5570).
I enabled the opencl USE flag on media-libs/mesa (to get the Clover OpenCL implementation), media-video/ffmpeg and media-libs/x264 (not globally) and they build successfully, but I haven't tried anything to verify OpenCL yet. Things that depend on them but that probably don't exercise OpenCL (e.g. glxgears, VLC playing a video) work properly.
These are installed:
| Code: | dev-libs/ocl-icd-2.2.12-r3
dev-util/clinfo-2.2.18.04.06-r1
dev-util/intel-ocl-sdk-2.0.31360
dev-util/opencl-headers-2020.03.13-r1
media-libs/mesa-19.3.5
media-video/ffmpeg-4.2.3
virtual/ffmpeg-9-r2
virtual/opencl-3-r1
x11-apps/mesa-progs-8.4.0

/etc/env.d/03opencl is currently set to Intel, and there is nothing under /usr/lib64/OpenCL/vendors/ocl-icd so I apparently can't fiddle with it to select ocl-icd.
A couple of packages that depend on ffmpeg but that do not themselves have a opencl use flag (chromium, qtwebengine) now fail to link (after a loooong build  ) with this:

...and Mesa Clover appears dead (no upstream commits in ten years).
I'm reluctant to just dive into dev-libs/amdgpu-pro-opencl because the AMD website for it claims loudly:
| Quote: | | This Radeon™ Software for Linux® release is only compatible with the Radeon RX 5700 Series of cards – no other products are supported. |
So, I'm asking for some advice. Is this hardware simply too old to try to use OpenCL at all and I should give up? Or will the dev-libs/amdgpu-pro-opencl package actually work and I should get that installed? Has anyone actually gotten OpenCL working with this generation of AMD GPU? Do I need to use an overlay?
Thanks! |

The compiler errors are because you have the intel libs installed - you shouldn't unless you have an Intel igp.
eselect-opencl and ocl-icd are both obsolete and should be uninstalled; if you insist on compiling things with USE=opencl, replace those with opencl-icd-loader first.
Clover is all you have on that card. Most of the things you're trying to compile with opencl support don't work with 1.1. amdgpu-pro absolutely won't work on a R600. It works with polaris10/11/12 though. |

Ok, thanks, I'll remove that. I'm not sure why that got installed...

Ugh, that isn't promising.
Thanks, I'll see where that takes me. |
