* @padding: padding to align to 8-byte
|
* @gpu_freq_khz_max: The maximum GPU frequency. Reported to applications by
|
* clGetDeviceInfo()
|
* @log2_program_counter_size: Size of the shader program counter, in bits.
|
* @texture_features: TEXTURE_FEATURES_x registers, as exposed by the GPU. This
|
* is a bitpattern where a set bit indicates that the format is supported.
|
* Before using a texture format, it is recommended that the corresponding
|
* bit be checked.
|
* @paddings: Padding bytes.
|
* @gpu_available_memory_size: Theoretical maximum memory available to the GPU.
|
* It is unlikely that a client will be able to allocate all of this memory
|
* for their own purposes, but this at least provides an upper bound on the
|
* memory available to the GPU.
|
* This is required for OpenCL's clGetDeviceInfo() call when
|
* CL_DEVICE_GLOBAL_MEM_SIZE is requested, for OpenCL GPU devices. The
|
* client will not be expecting to allocate anywhere near this value.
