As seen in the Vivante kernel driver, most GPUs with the BLT engine have a broken TS cache flush. The workaround is to temporarily set the BLT command to CLEAR_IMAGE, without actually executing the clear. Apparently this state change is enough to trigger the required TS cache flush. As the BLT engine is completely asychronous, we also need a few more stall states to synchronize the flush with the frontend.
