Did anyone get SVM to work? I'm having trouble with it both in the emulator and on the SoC.
Using the function "clGetDeviceInof" to query SVM capabilities I get the following positives:
CL_DEVICE_SVM_COARSE_GRAIN_BUFFER
CL_DEVICE_SVM_FINE_GRAIN_BUFFER
CL_DEVICE_SVM_FINE_GRAIN_SYSTEM
As far as I know this means I should be able to allocate memory with "clSVMAllocAltera", however the following call always returns NULL (emulator):
clSVMAllocAltera(context, CL_MEM_READ_WRITE | CL_MEM_SVM_FINE_GRAIN_BUFFER, 1024, 0)
Specifying an alignment value does not seem to help either. Unfortunately I don't know of any way to get further Information about what error occurred. I get a valid pointer when I remove the CL_MEM_SVM_FINE_GRAIN_BUFFER flag, but according to the device info call fine grained buffers should be available.
When building for the SoC I get various linker errors, so I haven't been able to test it there yet.
