* MIPS: Loongson: Mark cascade interrupts IRQF_NO_THREADWu Zhangjin2011-09-211-1/+2
| | | | | | | | | | | | | There are two cascade interrupts in Loongson machines, one for bonito northbridge, another for the 8259A controller in the southbridge. Both want to be non threaded.

* MIPS: Loongson: Remove unused macro LOONGSON_PERFCNT_IRQWu Zhangjin2010-08-051-1/+0
| | | | | | | | | | LOONGSON2_PERFCNT_IRQ is used for the irq number of the performance overflow interrupts; LOONGSON_PERFCNT_IRQ is unused so remove it.

* MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()Wu Zhangjin2010-08-051-3/+1
| | | | | | | | | | | | | | On FuLoong-2F IP6 is shared by the performance counter overflow interrupt and the Bonito northbridge interrupt. To reduce overhead only call do_IRQ() when oprofile is enabled to reduce overhead. This patch adds an inline function do_perfcnt_IRQ() to hide the #if's , which can be shared by the other Loongson machines, i.e. gdium.

* MIPS: Loongson: Remove set_irq_trigger_mode()Wu Zhangjin2010-08-051-7/+4
| | | | | | | | | | | | | set_irq_trigger_mode() is not needed on all platforms so remove it and move the related source code to mach_init_irq(). This will allow gdium to share the common irq.c without adding an empty set_irq_trigger_mode().

* MIPS: oprofile: Fix breakage when CONFIG_OPROFILE=mWu Zhangjin2010-04-301-1/+1
| | | | | | | | | | When the oprofile is compiled as a module do_IRQ() is not called in arch/mips/loongson/lemote-2f/irq.c due to a wrong #ifdef there.

* MIPS: Yeeloong 2F: Add LID open event as the wakeup eventWu Zhangjin2009-12-171-1/+3
| | | | | | | | | | | | | | Yeeloong 2F netbook has an KB3310B embedded controller to manage the LID action. When the LID is closed or opened a SCI interrupt is sent out and the corresponding event is saved to an EC register for later query. Allow the LID open interrupt to wake the processor from wait mode if it is in the suspend mode.

* MIPS: Lemote 2F: Add IRQ supportWu Zhangjin2009-12-171-0/+132
The generic i8259_irq() will make kernel hang on booting, so Loongson 2F needs its own polling method. IP6 is shared by the bonito interrupt and perfcounter interrupts.
