Hi,
I would prefer that you use the branch in the git tree below instead
which is the final correction

Hi Tixy,
These patches are mine and Olivier's, can you tell me what your config is to
see even a 90s boot? I haven't noticed any boot-time extension on my system,
but I'm booting from the A15 cluster. I'd like to reproduce your system here.
The build error is my mistake, I need to know which CP

With the coupled cpuidle driver (but probably also with other drivers),
a CPU loops in a temporary safe state while waiting for other CPUs of its
cluster to be ready to enter the coupled C-state. If an IRQ or a softirq
occurs, the CPU will stay in this internal loop if there is no need
to resched.
The function nohz_kick_needed modifies NOHZ_IDLE flag that is used to update
the nr_busy_cpus of the sched_group.
When the sched_domain are updated (because of the unplug of a CPUs as an
example) a null_domain is attached to CPUs. We have to test
likely(!on_null_domain(cpu) first in order to detect
The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
- when the SCHED softirq is raised on an idle core for idle load balance but
the platform doesn't go out of the cpuidle state
- when some CPUs enter id
On my smp platform which is made of 5 cores in 2 clusters,I have the
nr_busy_cpu field of sched_group_power struct that is not null when the
platform is fully idle. The root cause seems to be:
During the boot sequence, some CPUs reach the idle loop and set their
NOHZ_IDLE flag while waiting for oth

Hi Tixy,
I've got your kernel and the JB filesystem modified for USB booting here. There
is no boot delay for me - it takes just over 70s from boot monitor to mouse
pointer.
Catch you in the morning :)

Certain gcc tool chains convert the division on a 64-bit dividend into a
__aeabi_uldivmod call which does unnecessary 64-bit by 64-bit divides
although the divisor is 32-bit.This 64 by 64 bit division is not implemented
in the kernel for reasons of efficiency,which results in undefined reference

This adds following helper routines:
- of_property_read_u8_array()
- of_property_read_u16_array()
- of_property_read_u8()
- of_property_read_u16()
This expects arrays from DT to be passed as:
- u8 array:
property = /bits/ 8 <0x50 0x60 0x70>;
- u16 array:
property = /bits/ 16 <0x500
