2011-10-31mips: fix implicit smp.h usage in various files.Paul Gortmaker2-0/+2
We need to call out inclusion of smp.h, or with the module.h cleanup we'll get things like: arch/mips/loongson/common/platform.c:21: error: implicit declaration of function 'smp_processor_id' arch/mips/vr41xx/common/giu.c:84: error: implicit declaration of function 'smp_processor_id' arch/mips/vr41xx/common/rtc.c:85: error: implicit declaration of function 'smp_processor_id' Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2010-10-07MIPS: Add missing #inclusions of <linux/irq.h>David Howells2-0/+2
Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should really include it. Note that this can replace #inclusions of <asm/irq.h>. This is required for the patch to sort out irqflags handling function naming to compile on MIPS. The problem is that these files require access to things like setup_irq() - which isn't available by #including <linux/interrupt.h> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Ralf Baechle <ralf@linux-mips.org>

2007-02-06[MIPS] Make I8259A_IRQ_BASE customizableAtsushi Nemoto1-51/+2
Move I8259A_IRQ_BASE from asm/i8259.h to asm/mach-generic/irq.h and make it really customizable. And remove I8259_IRQ_BASE declared on some platforms. Currently only NEC_CMBVR4133 is using custom I8259A_IRQ_BASE value. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-06[MIPS] Define MIPS_CPU_IRQ_BASE in generic headerAtsushi Nemoto1-1/+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.

2006-12-06[MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu2-14/+5
__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.

2006-11-30[MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irqAtsushi Nemoto1-2/+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.

2006-11-30[MIPS] IRQ cleanupsAtsushi Nemoto2-50/+16
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.
