How To Begin Using OpenCL With Radeon Gallium3D

Earlier this month I wrote about how you can sort of begin using OpenCL acceleration out of the Radeon Gallium3D driver, but in the short time since, the code has continued to advance and now here's a guide for trying out this GPGPU computing technology on the open-source Radeon Linux driver.

AMD Is Still Struggling With HD 7000 On Catalyst

While most Linux enthusiasts know by now that there still isn't open-source Radeon HD 7000 series support from AMD under Linux, the Catalyst situation isn't so clear. While they've been committed to launch-day Catalyst hardware enablement under Windows and Linux, for the penguin OS that doesn't seem to always be the case for the HD 7000 series.

AMD Catalyst A.I. Useless Under Linux?

AMD today launched the Radeon HD 7570/7770 graphics cards as the latest GPUs built on the GCN architecture. Unfortunately there still is not any open-source support for the Radeon HD 7000 series hardware nor has AMD sent out any review samples to Phoronix. But there is some other Catalyst Linux news to share.

Image Quality Comparison: Radeon Gallium3D vs. Catalyst

Coming up in the next few days will be benchmarks of Mesa 8.0 with Morphological Anti-Aliasing (a.k.a. MLAA) plus some other imaging-oriented work/announcements to come in the near future. With that said, this weekend prior to leaving for Munich I ran some tests of the Radeon Gallium3D and Catalyst drivers when comparing the image quality.

Community Beats AMD To New Radeon Audio Code

It was just yesterday that I was writing about AMD still not having any new HDMI audio support code available to the public for the Radeon HD 5000 series and newer. The hold-up on this HDMI audio code for the open-source Radeon driver has been due to the patches failing to clear AMD's legal review multiple times. Well, leave it up the community, and now this morning there's some Evergreen patches for this support.
