* [MIPS] Define MIPS_CPU_IRQ_BASE in generic headerAtsushi Nemoto2007-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.

* [MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu2006-12-062-14/+0
| | | | | | | | | | | | | | | | | __do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

* [MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irqAtsushi Nemoto2006-11-302-2/+4
| | | | | | | | | | | | | | Further incorporation of generic irq framework. Replacing __do_IRQ() by proper flow handler would make the irq handling path a bit simpler and faster. * use generic_handle_irq() instead of __do_IRQ(). * use handle_level_irq for obvious level-type irq chips. * use handle_percpu_irq for irqs marked as IRQ_PER_CPU. * setup .eoi routine for irq chips possibly used with handle_percpu_irq.

* [MIPS] IRQ cleanupsAtsushi Nemoto2006-11-302-72/+17
| | | | | | | | | | | | | | | | | | | | | This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.
