is it possible to show currently used / free GPU free memory either with aticonfig or any other tool?
I'm using a HD7970 on Linux.
try look into AMD ADL SDK or OpenGL GL_ATI_meminfo extension.
I am not sure if you have posted the question in right category. As far as opencl is concerned you can get this information using clGetDeviceinfo API. Can you give more details about your intentions in knowing it using aticonfig?
As far as I know with clGetDeviceinfo I can only get the size of the usable global memory not the amount of free memory at runtime.
yes, that is true. But buffers are not tied to a device in OpenCL, so you may be able to create buffers of more memory than is currently free in the device.
