Comment on attachment 413860 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=413860&action=review r=me > Source/WebKit/ChangeLog:9 > + When enabling all GPU runtime flags on iOS, there is an iokit-open sandbox violation for the IOKit class AGXDeviceUserClient Is it a violation? Or just a violation report indicating that the access was allowed? I suspect it's the latter (i.e., we always allowed it, but we were logging in a case where we expected the access).

This was actually an IOKit open violation, which caused a crash. Thanks for reviewing!
