| Subject: MIPS: Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction |
| |
| From: Huacai Chen <chenhc@lemote.com> |
| |
| commit 0add9c2f1cff9f3f1f2eb7e9babefa872a9d14b9 upstream. |
| |
| HPET irq is routed to i8259 and then to MIPS CPU irq (cascade). After |
| commit a3e6c1eff5 (MIPS: IRQ: Fix disable_irq on CPU IRQs), if without |
| IRQF_NO_SUSPEND in cascade_irqaction, HPET interrupts will lost during |
| suspend. The result is machine cannot be waken up. |
