I'm chasing an issue that looks like retype'd memory has nonsense data. If I read the kernel code correctly it looks like the object returned by an seL4_UntypeRetype syscall should be zero'd (looks to happen when an untyped memory object is reset here https://github.com/seL4/seL4/blob/master/src/object/untyped.c#L254). Is that correct? I don't see anything called out in the manual
If the untyped isn't device untyped then it should be zeroed before it is
typed into an object. Device untyped is not allowed to be accessed by the kernel and so is not written to.
When are you observing the odd behaviour?
