cpuidle: Single/Global registration of idle states

2011-11-07T02:13:58Z

This patch makes the cpuidle_states structure global (single copy) instead of per-cpu. The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.

cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state

2011-11-07T02:13:30Z

Cpuidle governor only suggests the state to enter using the governor->select() interface, but allows the low level driver to override the recommended state. The actual entered state may be different because of software or hardware demotion. Software demotion is done by the back-end cpuidle driver and can be accounted correctly. Current cpuidle code uses last_state field to capture the actual state entered and based on that updates the statistics for the state entered. Ideally the driver enter routine should update the counters, and it should return the state actually entered rather than the time spent there. The generic cpuidle code should simply handle where the counters live in the sysfs namespace, not updating the counters.

serial: sh-sci: Fix up SH-2A SCIF support.

2011-11-04T13:33:30Z

This fixes up support for SH-2(A) SCIFs by introducing a new regtype. As expected, it's close to the SH-4A SCIF with fifodata, but still different enough to warrant its own type. Fixes up a number of FIFO overflows and similar for both SH7203/SH7264. Signed-off-by: Phil Edworthy Tested-by: Federico Fuga Signed-off-by: Paul Mundt

sh: kexec: Add PHYSICAL_START

2011-10-28T06:03:43Z

Add PHYSICAL_START kernel configuration parameter to set the address at which the kernel should be loaded. It has been observed on an sh7757lcr that simply modifying MEMORY_START does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such systems. Signed-off-by: Simon Horman Signed-off-by: Paul Mundt
