Hi, All
I am trying to debug my OpenCL code. I am using AMD gDEBugger 6.2 Catalyst 12.8 . I have HD7800 graphics adapter.
The program is very simple, i just create some buffers then set them as parameters to the kernel. and run kernel.
But at any point i cannot see contents of my buffers.
Here is how i create buffers:
cl_mem buf = clCreateBuffer(context, CL_MEM_READ_ONLY|CL_MEM_HOST_WRITE_ONLY, size, 0, &status);
status = clEnqueueWrite(queue, buf, TRUE, size, pdata, 0,0,0);
then i set it up like this:
status = clSetKernelArg(my_kernel, 0, sizeof(cl_mem), (void*)&buf);
check_status;
and execute my kernel:
const size_t gws[2] = { 16, 16};
cl_event eventND[1];
clEnqueueNDRangeKernel(queue, my_kern, 2, NULL, (const size_t*)gws, 0,0,0, eventND);
check_status;
then i wait for event:
while(st!=CL_COMPLETE)
{
status = clGetEventInfo(..., &st, NULL);
check_status;
}
part of my kernel :
__kernel void my_kern(
__global CHUNK_DATA* pcd,
__constant int* buf // c++ example was shown for this buffer, but pcd is created in same way
//.. other __constant buffers (total about 16, max available for my adapter is 8 but i assume, driver merges some of them, so there are no errors)
)
{
...
}
I've checked, there are no CL errors. I tried to run on bot GPU and CPU and have same problem.
Any thoughts on where can be a problem?
Thanks
check_status;
