The open-source AMD RadeonSI
Gallium3D driver is beginning to work when it comes to running simple OpenCL programs on the Radeon HD 7000 series graphics cards.
The open-source AMD OpenCL support is in even worse shape than the lacking and not-always-fast OpenGL support, but in the past few months for the HD 5000/6000 series hardware with the R600g driver it's begun to work for simple and small OpenCL programs, including open-source Bit Coin mining
. Now the RadeonSI Gallium3D OpenCL support is beginning to run small OpenCL exercises too, and the ability to run "bfgminer" for those into open-source currency mining.
AMD's Tom Stellard noted with a new patch series
, "These patches along with the associated LLVM changes improve compute support on radeonsi to the point were it can run a number of simple apps, including the bitcoin mining program bfgminer."
