Luck has it that the AMDGPU driver supports opencl now and is available.\r\nwhen I run ethminer --list-devices I get this:\r\nListing OpenCL devices.\r\nFORMAT: [deviceID] deviceName\r\n[0] AMD PITCAIRN (DRM 2.43.0, LLVM 3.8.0)\r\n\tCL_DEVICE_TYPE: GPU\r\n\tCL_DEVICE_GLOBAL_MEM_SIZE: 1073741824\r\n\tCL_DEVICE_MAX_MEM_ALLOC_SIZE: 268435456\r\n\tCL_DEVICE_MAX_WORK_GROUP_SIZE: 256\r\n\r\nThe CL Device Global Mem size is set to 50%. The old commands to increase heap size and single alloc that worked with the old drivers doesn't work anymore. I ran:\r\nexport GPU_FORCE_64BIT_PTR=0\r\nexport GPU_MAX_HEAP_SIZE=100\r\nexport GPU_USE_SYNC_OBJECTS=1\r\nexport GPU_MAX_ALLOC_PERCENT=100\r\nexport GPU_SINGLE_ALLOC_PERCENT=100\r\n\r\nNone of them were able to increase the memory the size remains the same. Does anyone know how to free my memory using the new amdgpu kernel driver in Ubuntu 16.04? My R9 290 is sitting idle, i'll tip whoever gives me an answer :)\r\n\r\nRgds\r\n"}}
