For now, it's detected only via OpenCL (like Intel GPUs).
Eventually we'll detect via Metal as well.
Plan classes for Apple GPU must include 'apple_gpu' in their name.
The changes are mostly copy-and-paste of Intel GPU code.
I hate duplicate code but I don't know how to fix.
For now, handle AMD/ATI, NVIDIA or Intel GPUs as before. But for other, "new" vendors, we treat each device as a separate resource, creating an entry for each instance in the COPROCS::coprocs[] array and copying the device name COPROC::opencl_prop.name into the COPROC::type field (instead of the vendor name.)
For devices from "new" vendors, set <gpu_type> field in init_data.xml file to the vendor string supplied by OpenCL. This should allow boinc_get_opencl_ids() to work correctly with these "new" devices without modification.
Notes:
- The same CPU can have a different cpu_opencl_prop for each of multiple OpenCL platforms. We send them all to the project server because:
- Different OpenCL platforms report different values for the same CPU.
- Some OpenCL CPU apps may work better with certain OpenCL platforms.
- OpenCL has only 64 bits for global_mem_size, so it can report a max of only 4GB; get the CPU RAM size from gstate.hostinfo.m_nbytes.
