Expand description
Struct that defines a upcall that can be passed to a process. The upcall
takes four arguments that are Driver
and upcall specific, so they are
represented generically here.
Likely these four arguments will get passed as the first four register values, but this is architecture-dependent.
A FunctionCall
also identifies the upcall that scheduled it, if any, so
that it can be unscheduled when the process unsubscribes from this upcall.
Fields§
§source: FunctionCallSource
Whether the kernel called this directly or this is an upcall.
argument0: usize
The first argument to the function.
argument1: usize
The second argument to the function.
argument2: usize
The third argument to the function.
argument3: CapabilityPtr
The userdata provided by the process via subscribe
pc: CapabilityPtr
The PC of the function to execute.
