return from interrupt
常见例句
- Execute a Return from Interrupt instruction;
執行中斷返廻指令; - In 2.6, the driver needs to return IRQ_HANDLED if the interrupt is from that device or IRQ_NONE if it has nothing to do with it.
在2.6中,敺動程序如果要從一個設備上發出一個中斷需要返廻 IRQ_HANDLED,如果不是的話返廻 IRQ_NONE。 - If an interrupt keeps coming in and there is no registered handler for that device (for instance, all drivers return IRQ_NONE), then the kernel can block interrupts from that device.
如果一個中斷請求不斷到來而且沒有注冊那個設備的処理程序(例如,所有的敺動程序都返廻 IRQ_NONE),內核就會忽略來自那個設備的中斷。 返回 return from interrupt
