Attribute Macro panda_macros::guest_hypercall

#[guest_hypercall]

(Callback) Called when a program inside the guest makes a hypercall to pass information from inside the guest to a plugin

Callback ID: PANDA_CB_GUEST_HYPERCALL

   Arguments:
    CPUState *env: the current CPU state

   Helper call location: target/i386/misc_helper.c

   Return value:
    true if the callback has processed the hypercall, false if the
    hypercall has been ignored.

   Notes:
    On x86, this is called whenever CPUID is executed. On ARM, the
    MCR instructions is used. Plugins should check for magic values
    in the registers to determine if it really is a guest hypercall.
    Parameters can be passed in other registers. If the plugin
    processes the hypercall, it should return true so the execution
    of the normal instruction is skipped.

Callback arguments: (&mut CPUState, )

Example

use panda::prelude::*;

#[panda::guest_hypercall]
fn callback(_: &mut CPUState, ) -> bool {
    // do stuff
}
