[JustinCappos]

I find this confusing. I don't really understand. Is there a location where this information is stored that persists? Do we just do a table lookup for this?

[JustinCappos]

I do still need some help here. Is this really a Rust problem? Isn't this that you need to restore the state and you don't get passed what you need lower in the call stack?

[JustinCappos]

I think that 3i will contain the information (in the optional info of the register_handler / make_syscall calls) to handle this. Do you need a table still?

[JustinCappos]

Sorry, this only contains the jump address. If the tid / pid (cageid) are consistent, then I think you could look this up in the cases you need the context.

[JustinCappos]

I'm realizing we also need an explanation of how the stack looks and where it lives, etc. I find this part very confusing. How do we return back up the call stack after a series of grates?

[JustinCappos]

I need some clarity here too. Probably need to chat.

[JustinCappos]

I made the fixes I could. Needs more discussion. Happy to work more on this once I understand a few things.

[JustinCappos]

I do still need some help here. Is this really a Rust problem? Isn't this that you need to restore the state and you don't get passed what you need lower in the call stack?

[JustinCappos]

I need some clarity here too. Probably need to chat.

[JustinCappos]

Does the tid indicate which VMContext is used to run a request in the grate?

[rennergade]

i think the thread per instance distinction needs to move closer to the beginning, also some confusion in module vs instance on my end

[rennergade]

asked for a minor clarification but this makes sense to me

[JustinCappos]

What does it mean to capture here? Is this just putting a pointer in or are you copying a data structure?

Do these pointers ever change or are they the same for a Context throughout its lifetime?
