Now we have a SPURR cpu feature bit, we can export it to userspace in
sysfs.

[POWERPC] Add DSCR SPR to sysfs

2006-12-09T00:39:05+00:00

POWER6 adds a new SPR, the data stream control register (DSCR). It can
be used to adjust how agressive the prefetch mechanisms are.

Its possible we may want to context switch this, but for now just export
it to userspace via sysfs so we can adjust it.

[PATCH] i386: change the 'no_control' field to 'hotpluggable' in the struct cpu

2006-12-07T01:14:10+00:00

Change the 'no_control' field in the cpu struct to a more positive
and better term 'hotpluggable'. And change(/cleanup) the logic accordingly.

[POWERPC] sysfs: add support for adding/removing spu sysfs attributes

2006-10-25T04:20:22+00:00

This patch adds two functions to create and remove sysfs attributes and
attribute_group to all cpus.  That allows to register sysfs attributes in
a subdirectory like: /sys/devices/system/cpu/cpuX/group_name/what_ever
This will be used by cbe_thermal to group all attributes dealing with
thermal support in one directory.

[POWERPC] Always call cede in pseries dedicated idle loop

2006-09-26T05:24:34+00:00

The smt_snooze_delay logic changed a bit when the idle loops were
consolidated. A value of 0 used to mean we always polled, now it means
we always sleep. Instead of restoring the old behaviour, lets put a
reasonable default in smt_snooze_delay. This means we spin for a bit
(in case an external interrupt comes in) and then sleep.

Also the pseries dedicated idle loop currently does not cede both
threads in an SMT pair. The hypervisor wants us to call in so it can
power manage, so lets do that.

[PATCH] cpu hotplug: replace devinit* with cpuinit* for cpu notifications

2006-07-31T20:28:39+00:00

Few of the callback functions and notifier blocks that are associated with cpu
notifications incorrectly have __devinit and __devinitdata.  They should be
__cpuinit and __cpuinitdata instead.

It makes no functional difference but wastes text area when CONFIG_HOTPLUG is
enabled and CONFIG_HOTPLUG_CPU is not.

This patch fixes all those instances.

[POWERPC] Constify & voidify get_property()

2006-07-31T05:55:04+00:00

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

powerpc core changes.
