2007-06-21[MIPS] Don't drag a platform specific header into generic arch code.Ralf Baechle7-52/+34

2007-02-27[MIPS] Kill redundant EXTRA_AFLAGSAtsushi Nemoto1-2/+0
Many Makefiles in arch/mips have EXTRA_AFLAGS := $(CFLAGS) line. This is redundant while AFLAGS contains $(cflags-y) and any options only listed in CFLAGS (not in cflags-y) should be unnecessary for asm sources.

2007-02-06[MIPS] Define MIPS_CPU_IRQ_BASE in generic headerAtsushi Nemoto4-7/+5
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.

2006-11-30[MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irqAtsushi Nemoto3-2/+5
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 Nemoto1-22/+6
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.

2006-09-27[MIPS] Patch to arch/mips/mips-boards/generic/time.cKevin D. Kissell1-21/+36
In hooking up the perf counter overflow interrupt to the experimental deprecated-real-soon-now /proc/perf interface last night, I had to revisit arch/mips/mips-boards/generic/time.c, and discovered that when the 2.6.9-based SMTC prototype was merged with the more recent tree, it was missed that arch/mips/kernel/time.c had changed so that even in SMP kernels, timer_interrupt() calls local_timer_interrupt(), so there is no longer a need to invoke it directly from mips_timer_interrupt() in those cases where timer_interrupt() has been called. So I got rid of that, and added the invocation of perf_irq() if Cause.PCI is set, more-or-less following the same logic as in the non-SMTC case, with the modifications that (a) a runtime check for Release 2 isn't done, because it's redundant in SMTC), and (b) we check for a clock interrupt regardless of the value returned by the perf counter service - I don't understand why we'd want to control that with perf_irq(), but maybe one of you knows the story. I also got rid of the stupid warning about the unused variable when compiled for SMTC (another artifact of the merge). The result hasn't been beaten to death, but boots, seems stable, and supports extended precision event counting. Signed-off-by: Kevin D.

2006-07-11[PATCH] tty: Remove include of screen_info.h from tty.hJon Smirl1-1/+1
screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.
