(Get the code!)
Hello @kaihengfeng, In your test (bug #1858751, post #4):
>Running glxgears at 4K, and it keeps 60FPS after running an hour.
>glxgears dropped to 10 FPS after 5 mins with original firmware.
What is the device under test? In my case (device 0x1002:0x6604) - no such problem before update - speed shakes between 59.98-60.00FPS for half hour, spread uniformly (only 3 samples are below 59.99!). Next the update, everything fail! Different firmware for different devices might be needed (the driver responsibility).
