The following series consists of a bunch of fixes for
cpuidle back-end driver for ppc64 (pSeries) platform.
The series applies on 3.6-rc7 and has been tested on ppc64 pSeries
POWER7 system with snooze and nap states.
With these fixes, avg idle residency for nap on 50 percent idle system
smt_snooze_delay was designed to delay idle loop's nap entry
in the native idle code before it got ported over to use as part of
the cpuidle framework.
A -ve value assigned to smt_snooze_delay should result in
busy looping, in other words disabling the entry to nap state.
-
Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states. smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different
Remove the redundant target residency initialisation in
pseries_cpuidle_driver_init().
This is currently over-writing the residency time updated as part of the static
table, resulting in all the idle states having the same target
residency of 100us which is incorrect. This may result in the menu

Running below Coccinelle lookup pattern like below on the
latest kernel showed about 52 hits. This patch series is a subset
of those 52 patches, so that it will be easy for maintainers to review.
Hopefully these patches will get rid of some

Hi,
The current virtual address space of a 32-bit userspace process looks
like this on powerpc:
# cat /proc/28922/maps
0010-00102000 r-xp 00:00 0 [vdso]
Currently, when booting MPC52xx based platforms, we get:
mpc52xx_irqhost_map: invalid irq: virq=16, l1=0, l2=3
irq: irq-16==hwirq-0x3 mapping failed: -22
[WARNing skipped]
The warning is wrong since the mapping itself is valid. However, there is no
support for that type
