2011-09-21MIPS: Loongson: Mark cascade interrupts IRQF_NO_THREADWu Zhangjin
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.

2010-08-05MIPS: Loongson: Remove unused macro LOONGSON_PERFCNT_IRQWu Zhangjin
LOONGSON2_PERFCNT_IRQ is used for the irq number of the performance overflow interrupts; LOONGSON_PERFCNT_IRQ is unused so remove it.

2010-08-05MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()Wu Zhangjin
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.

2010-08-05MIPS: Loongson: Remove set_irq_trigger_mode()Wu Zhangjin
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().

2010-04-30MIPS: oprofile: Fix breakage when CONFIG_OPROFILE=mWu Zhangjin
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.

2010-02-27MIPS: Loongson: Lemote-2F: Get the machine type from PMON_VERWu Zhangjin
Lemote have used the PMON_VER strings to indicate the loongson-2f machine series: PMON_VER=LM8089 Lemote 8.9'' netbook LM8101 Lemote 10.1'' netbook (The above two netbooks have the same kernel support) LM6XXX Lemote FuLoong(2F) box series LM9XXX Lemote LynLoong PC series Before the machtype is supported by the PMON, we can get the machine type from the PMON_VER for these machines, this will help the users a lot.

2009-12-17MIPS: Lemote 2F: Suspend CS5536 MFGPT TimerWu Zhangjin
Before putting the Loongson 2F into wait mode, suspend the MFGPT Timer and after wake-up resume it. This may save some power.

2009-12-17MIPS: Yeeloong 2F: Add LID open event as the wakeup eventWu Zhangjin
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.

2009-12-17MIPS: Lemote 2F: Add NAS supportWu Zhangjin
Kernel support for this machine is almost the same as Fuloong 2F; the only difference is that it uses the serial port provided by Loongson 2F processor as Yeeloong 2F does.

2009-12-17MIPS: Yeeloong 2F: Add board specific suspend supportWu Zhangjin
Lemote Loongson 2F family machines need an external interrupt to wake the system from the suspend mode. For YeeLoong 2F and Mengloong 2F setup the keyboard interrupt as the wakeup interrupt. The new Fuloong 2F and LingLoong 2F have a button to directly send an interrupt to the CPU so there is no need to setup an interrupt.

2009-12-17MIPS: Lemote 2F: Add IRQ supportWu Zhangjin
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.
