source · #[asid_changed]
Expand description
(Callback) Called when asid changes.
Callback ID: PANDA_CB_ASID_CHANGED
Arguments:
CPUState *env: pointer to CPUState
target_ptr_t oldval: old asid value
target_ptr_t newval: new asid value
Helper call location: target/i386/helper.c, target/arm/helper.c
Return value:
true if the asid should be prevented from being changed
false otherwise

The callback is only invoked implemented for x86 and ARM.
This should break plugins which rely on it to detect context
switches in any other architecture.
Callback arguments: (&mut CPUState
, target_ptr_t
, target_ptr_t
, )
Example
use panda::prelude::*;
#[panda::asid_changed]
fn callback(_: &mut CPUState, _: target_ptr_t, _: target_ptr_t, ) -> bool {
// do stuff
}
