Sometimes when using qtcreator for a while a gpu lockup error occurred, on this basis, we guess that this gpulock error caused by qtcreator's welcome plugin, so we use a script to test the qtcreator's Welcome plugin as follows:

while true do for i in `seq 100` do qtcreator -test Welcome & done wait done

The time of the error is random, and sometimes appear once a half hour, sometimes half a day, that is , not a fixed time. Currently we have tried a lot of ways to deal with cpu and gpu out of sync. E.g: dpm=0/pm_method=profile. Pipeline timeout. Use GTT for stream resources.
