genirq: Support per-IRQ thread disabling.

2011-04-23T13:56:24Z

This adds support for disabling threading on a per-IRQ basis via the IRQ status instead of the IRQ flow, which is necessary for interrupts that don't follow the natural IRQ flow channels, such as those that are virtually created. The new APIs added are simply: irq_set_thread() irq_set_nothread() which follow the rest of the IRQ status routines. Chained handlers also have IRQ_NOTHREAD set on them automatically, making the lack of threading explicit rather than implicit. Subsequently, the nothread flag can be viewed through the standard genirq debugging facilities.

genirq: Remove desc->status when GENERIC_HARDIRQS_NO_COMPAT=y

2011-02-19T11:58:22Z

If everything uses the right accessors, then enabling GENERIC_HARDIRQS_NO_COMPAT should just work. If not it will tell you. Don't be lazy and use the trick which I use in the core code! git grep status_use_accessors will unearth it in a split second. Offenders are tracked down and not slapped with stinking trouts. This time we use frozen shark for a better educational value. Signed-off-by: Thomas Gleixner

genirq: Cleanup irq.h

2011-02-19T11:58:21Z

Put the constants into an enum and document them. Signed-off-by: Thomas Gleixner

genirq: Force wrapped access to desc->status in core code

2011-02-19T11:58:21Z

Force the usage of wrappers by another nasty CPP substitution. Signed-off-by: Thomas Gleixner

genirq: Wrap the remaning IRQ_* flags

2011-02-19T11:58:21Z

Use wrappers to keep them away from the core code. Signed-off-by: Thomas Gleixner

genirq: Mirror irq trigger type bits in irq_data.state

2011-02-19T11:58:20Z

That's the data structure chip functions get provided. Also allow them to signal the core code that they updated the flags in irq_data.state by returning IRQ_SET_MASK_OK_NOCOPY. The default is unchanged. The type bits should be accessed via: val = irqd_get_trigger_type(irqdata); and irqd_set_trigger_type(irqdata, val); Coders who access them directly will be tracked down and slapped with stinking trouts.

genirq: Move IRQ_AFFINITY_SET to core

Keep status in sync until last abuser is gone. Signed-off-by: Thomas Gleixner

genirq: Mirror IRQ_PER_CPU and IRQ_NO_BALANCING in irq_data.state

2011-02-19T11:58:20Z

That's the right data structure to look at for arch code. Accessor functions are provided. irqd_is_per_cpu(irqdata); irqd_can_balance(irqdata); Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner

genirq: Add IRQ_MOVE_PENDING to irq_data.state

2011-02-19T11:58:18Z

chip implementations need to know about it. Keep status in sync until all users are fixed. Accessor function: irqd_is_setaffinity_pending(irqdata) Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner
