alpha: Use generic show_interrupts()

2011-03-29T12:47:58+00:00

The only subtle difference is that alpha uses ACTUAL_NR_IRQS and
prints the IRQF_DISABLED flag.

Change the generic implementation to deal with ACTUAL_NR_IRQS if
defined.

The IRQF_DISABLED printing is pointless, as we nowadays run all
interrupts with irqs disabled.

alpha: irq: Convert affinity to use irq_data

2011-03-02T19:57:59+00:00

affinity is moving to irq_data. Fix it up.

alpha: fix WARN_ON in __local_bh_enable()

Interrupts ought to be disabled _before_ irq_enter().

alpha: kill off alpha_do_IRQ

2011-01-17T04:42:13+00:00

Good riddance... Nuke a pile of redundant handlers that the
generic code takes care of as well.

alpha: irq clean up

2011-01-17T04:42:12+00:00

Stop touching irq_desc[irq] directly, instead use accessor
functions provided. Use irq_has_action instead of directly
testing the irq_desc.

alpha: use set_irq_chip and push down __do_IRQ to the machine types

2011-01-17T04:42:11+00:00

Also kill superfluous IRQ_DISABLED initialization, since that's the
default state of the irq_desc[i].status field.

alpha: add performance monitor interrupt counter

2010-08-10T03:45:03+00:00

The following patches implement hardware performance events for the Alpha
EV67 and later CPUs.  I have had this running on a Compaq XP1000 (EV67,
single CPU) for a few days now.  Pretty cool -- discovered that the glibc
exp2() library routine uses on average 985 cycles to execute 777 CPU
instructions whereas Compaq's CPML library version of exp2() uses on
average 32 cycles to execute 47 CPU instructions to achieve the same
thing!

This patch:

Add performance monitor interrupt counternd and export the count to user
space via /proc/interrupts.
