IrqDisabledToken

strat9_kernel::sync

Struct IrqDisabledToken 

Source 
pub struct IrqDisabledToken(/* private fields */);
Expand description

Preuve typée que les IRQ sont masquées sur le CPU courant.

L’allocateur mémoire consomme ce token pour empêcher à la compilation les appels depuis des contextes où une interruption pourrait ré-entrer sur le même verrou et provoquer un deadlock.

Intentionnellement non-Copy et non-Clone : le token ne doit pas pouvoir s’échapper du contexte IRQ-off dans lequel il a été créé.

Implementations§

Source§

impl IrqDisabledToken
