This patch causes a warning:
/home/yr /beignet/src/cl_khr_icd.c:187:3: warning: initialization from
incompatible pointer type
clGetKernelSubGroupInfoKHR,
/home/yr/maintain/beignet/src/cl_khr_icd.c:187:3: warning: (near initialization
for ‘cl_khr_icd_dispatch.clUnknown136’)
I checked the 2.2.8's ocl_icd.h:
#ifdef CL_VERSION_2_0
CL_API_ENTRY cl_int (CL_API_CALL*clGetKernelSubGroupInfoKHR)(
cl_kernel /* in_kernel */,
cl_device_id /*in_device*/,
cl_kernel_sub_group_info /* param_name */,
size_t /*input_value_size*/,
const void * /*input_value*/,
size_t /*param_value_size*/,
void* /*param_value*/,
size_t* /*param_value_size_ret*/ ) CL_EXT_SUFFIX__VERSION_2_0;
#else
CL_API_ENTRY cl_int (CL_API_CALL* clUnknown136)(void);
#endif
clGetKernelSubGroupInfoKHR is available from OpenCL2.0, also need OpenCL
version check in beignet?
BTW: ocl-icd 2.2.8's OCL_ICD_IDENTIFIED_FUNCTIONS is 128, is it a typo?
