items. Currently, the clEnqueueNDRangeKernel flushes the batchbuffer every time, and thus the clFlush is also an empty function. We also need to optimize it to track the states and avoid some unnecessary pipe controls for each kernel. But our team’s current
focus is to implement the missing opencl features, and try hard to pass the piglit test. After that, we will turn to these items. And as usual, if everyone from the community want to contribute on these items, we will be more than happy to review and accept
it.<o:p></o:p></span></p>
