[MIPS] kgdb: add arch support for the kernel's kgdb core

2008-07-30T20:54:42Z

The new kgdb architecture specific handler registers and unregisters dynamically for exceptions depending on when you configure a kgdb I/O driver. Aside from initializing the exceptions earlier in the boot process, kgdb should have no impact on a device when it is compiled in so long as an I/O module is not configured for use. There have been quite a number of contributors during the existence of this patch (see arch/mips/kernel/kgdb.c). Most recently Jason re-wrote the mips kgdb logic to use the die notification handlers.

[MIPS] kgdb: Remove existing implementation

2008-07-30T20:54:42Z

This patch explicitly removes the kgdb implementation, for mips which is intended to be followed by a patch that adds a kgdb implementation for MIPS that makes use of the kgdb core in the kernel. Signed-off-by: Jason Wessel Signed-off-by: Ralf Baechle

[MIPS] unexport {allocate,free}_irqno

2008-07-15T17:44:29Z

The following routines allocate_irqno() free_irqno() seem not to be used outside of the core kernel code, hence exporting these functions is pointless. This patch removes the export. Signed-off-by: Dmitri Vorobiev Signed-off-by: Ralf Baechle

MIPS: Mark all but i8259 interrupts as no-probe.

2008-02-08T17:22:42Z

Use set_irq_noprobe() to mark all MIPS interrupts as non-probe. Override that default for i8259 interrupts. Signed-off-by: Ralf Baechle Acked-and-tested-by: Rob Landley Cc: Alan Cox Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[MIPS] SMTC: Make ack_bad_irq() safe with no IM backstop.

Issue reported and original patch by Kevin Kissel, cleaner (imho) implementation by me. Signed-off-by: Ralf Baechle

[MIPS] Drop __devinit tag from allocate_irqno() and free_irqno()

2007-05-11T13:28:31Z

This fix these warnings: WARNING: arch/mips/kernel/built-in.o - Section mismatch: reference to .init.text:free_irqno from __ksymtab_gpl between '__ksymtab_free_irqno' (at offset 0x0) and '__ksymtab_allocate_irqno' WARNING: arch/mips/kernel/built-in.o - Section mismatch: reference to .init.text:allocate_irqno from __ksymtab_gpl after '__ksymtab_allocate_irqno' (at offset 0x8) Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] genirq: use name instead of typename

2006-12-06T20:16:08Z

The "typename" field was obsoleted by the "name" field. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] do_IRQ cleanup

2006-11-30T01:14:49Z

Now we have both function and macro version of do_IRQ() and the former is used only by DEC and non-preemptive kernel. This patch makes everyone use the macro version and removes the function version. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] IRQ cleanups

2006-11-30T01:14:46Z

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. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle
