Do we have something like a kmsdump tool?

[Christian König]

Hi guys,

we are currently debugging a problem with some on screen artifacts and 
I'm wondering if we have some sort of kmsdump tool already?

E.g. similar like kmsgrab which gets a reference to the DMA-buf file 
descriptor which is currently displayed and then mmaping that or 
importing it into VAAPI or stuff like that. But instead writing the 
content to a file for debugging.

Thanks,
Christian.
