C-state/P-state spew fills xm dmesg buffers
I''ve noticed with xen-unstable on my quad-core x dual-thread
(that''s 8 processors to xen), the boot info spewed for all
the C-state/P-state stuff quickly fills the xm dmesg buffer
and I lose some of the early-in-boot lines. Do we really
need to know "reg.{space_id,bit_width,bit_offset,access_size,
address}" and all that other info? Even if so, is there
a more compact way to print it?

Kernel crash with acpi_processor, cpu_idle and intel_idle =y
Hi everyone,
When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE
to y then I cannot boot Xen; there is a crash. If I turn
CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has
booted, xenpm works and gives some sane output, see below. I have
tested this with kernels 3.2 to 3.4.6.
Is it impossible to use INTEL_IDLE with Xen? If this is a known issue
then maybe

[RFC PATCH] Exporting ACPI Pxx/Cxx states to other kernel subsystems (v1).
Hello,
The following patches are a solution to a problem we have encountered
when using the Xen hypervisor:
- Need Pxx/Cxx states to save on power consumption when using Xen (we
do want those datacenters to consume less power!),
- Also need to figure out the Turbo mode so that the scheduler can properly
boost a core for CPU bound guests.
In essence the Xen hypervisor requires that
