[Mesa-dev] OpenCL for radeon Hawaii?

[Sam Halliday]

Hello everybody,

I recently got a Radeon R9 290x (aka Hawaii). I run ArchLinux, which has
mesa 12.0.1.

I am keen to try out mesa's partial OpenCL implementation. Ideally to
use a BLAS implementation such as https://github.com/CNugteren/CLBlast
but I'd also be happy to just write something basic like dense
matrix/matrix multiplication in OpenCL.


However, when I tried to run the "luxmark" OpenCL benchmark (the only
way I could think to test if my card is supported), I got this error

[PathOCLBaseRenderThread::0] Compiling kernels 
[PathOCLBaseRenderThread::0] PathOCL kernel compilation error ERROR clBuildProgram[CL_INVALID_BUILD_OPTIONS]: 
RUNTIME ERROR: PathOCLBase kernel compilation error

which, I'm guessing, means that my GPU isn't supported for OpenCL by
mesa yet. Is that correct? (I don't know how to get any more output or
logs than this).


Could somebody please help by letting me know if there is a ticket I
could subscribe to track progress of support for my card (a simple
search of the bug database didn't bring up anything obvious). This
message is to the -dev list, so I am suppose I am saying that I am
prepared to get my hands dirty... but I am primarily a Scala developer
and haven't done any C in years so the extent of my help is limited.

If somebody who knows what they are doing would be willing to implement
some of the functionality needed, I'd be prepared to buy this GPU for
them to use for their hacking - it's the least I could do (but it is an
absolute monster, I didn't even know GPUs could be this big! I needed to
get a bigger case for it).


Somewhat tangentially, if OpenCL support is really not a possibility
anytime soon, could somebody please point me in the direction of a way
to use this card programmatically for something like matrix/matrix
multiplication? (I'm prepared to go really low level if there is
sufficient documentation).


I'm not at all interested in using proprietary drivers for OpenCL.
