[PATCH] request_irq(): remove warnings from irq probing

2006-04-28T15:33:46+00:00

- Add new SA_PROBEIRQ which suppresses the new sharing-mismatch warning.
  Some drivers like to use request_irq() to find an unused interrupt slot.

- Use it in i82365.c

- Kill unused SA_PROBE.

[PATCH] warn if free_irq() is called from IRQ context

2006-03-26T16:56:53+00:00

Warn if free_irq() is called in IRQ context - free_irq() can execute /proc
VFS work, which must not be done in IRQ context.

[PATCH] Add SA_PERCPU_IRQ flag support

2006-03-25T16:23:01+00:00

Add support for SA_PERCPU_IRQ (only mmtimer.c uses this at this stage).

[PATCH] IRQ: prevent enabling of previously disabled interrupt

2006-03-25T16:22:55+00:00

This fix prevents re-disabling and enabling of a previously disabled
interrupt.  On an SMP system with irq balancing enabled; If an interrupt is
disabled from within its own interrupt context with disable_irq_nosync and is
also earmarked for processor migration, the interrupt is blindly moved to the
other processor and enabled without regard for its current "enabled" state.
If there is an interrupt pending, it will unexpectedly invoke the irq handler
on the new irq owning processor (even though the irq was previously disabled)

The more intuitive fix would be to invoke disable_irq_nosync and
enable_irq, but since we already have the desc->lock from __do_IRQ, we
cannot call them directly.  Instead we can use the same logic to disable
and enable found in disable_irq_nosync and enable_irq, with regards to the
desc->depth.

This now prevents a disabled interrupt from being re-disabled, and more
importantly prevents a disabled interrupt from being incorrectly enabled on
a different processor.

[PATCH] kernel/: small cleanups

2006-01-09T04:13:48+00:00

This patch contains the following cleanups:
- make needlessly global functions static
- every file should include the headers containing the prototypes for
  it's global functions

[PATCH] Alpha: convert to generic irq framework (generic part)

2006-01-06T16:33:40+00:00

Thanks to Christoph for doing most of the work.

This allows automatic SMP IRQ affinity assignment other than default "all
interrupts on all CPUs" which is rather expensive.  This might be useful if
the hardware can be programmed to distribute interrupts among different
CPUs, like Alpha does.
