zero-copy Out of bound access

Will an out-of-bound access by a kernel on a zero-copy buffer result in system in-stablity?

What is the expected outcome?

If it is global memory - we know it is a segfault.

If it is zero-copy memory - what will be the effect?

Unspecified launch error, just like global memory.

Vow! Thats wonderful! Thanks!

Is it guaranteed that every such single attempt will be trapped and wrapped up as a launch failure?

Why I ask this is – May b, the implementation maps a PCI-e bus error (like target abort) to launch failure and not actively check each and every access…

Thanks!
