[POWERPC] PA6T PMC support

2007-02-07T03:03:19Z

Support for PA6T-style PMC registers. PMCs are completely implementation-dependent on PPC, and PA6T numbers them differently from the IBM model. Signed-off-by: Olof Johansson Signed-off-by: Paul Mackerras

[POWERPC] Add SPURR SPR to sysfs

2006-12-09T00:39:06Z

Now we have a SPURR cpu feature bit, we can export it to userspace in sysfs. Signed-off-by: Anton Blanchard Signed-off-by: Paul Mackerras

[POWERPC] Add DSCR SPR to sysfs

2006-12-09T00:39:05Z

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. Signed-off-by: Anton Blanchard Signed-off-by: Paul Mackerras

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

2006-12-07T01:14:10Z

Change the 'no_control' field in the cpu struct to a more positive and better term 'hotpluggable'. And change(/cleanup) the logic accordingly. Signed-off-by: Suresh Siddha Signed-off-by: Andi Kleen Cc: Andi Kleen Cc: "Li, Shaohua" Signed-off-by: Andrew Morton

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

2006-10-25T04:20:22Z

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

2006-09-26T05:24:34Z

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.

[POWERPC] Enable PURR sysfs entry correctly

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

2006-07-31T20:28:39Z

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.
