GPU Command and Syncpoint Analysis on SM8650 Platform

On the SM8650 platform, GLES issues synchronous and draw commands that the kernel‑mode driver translates into kgsl_drawobj structures, queues them in per‑context dispatch lists, processes fence, timestamp, and timeline syncpoints via dedicated kernel threads, and finally submits draw objects to the GPU firmware, with eglSwapBuffers triggering a fence syncpoint, a draw command, and a GPU fence creation.
