Hi All,
Here is my first take at implementing an idle PM governor that takes
full advantage of NO_HZ. I call it the 'menu' governor because it
considers the full list of idle states before each entry.
I've kept the implementation fairly simple. It attempts to guess the
next residency time and t
This patch prepares cpuidle for the menu governor. It adds an optional
stage after idle state entry to give the governor an opportunity to
check why the state was exited. Also it makes sure the idle loop
returns after each state entry, allowing the appropriate dynticks code
to run.
Thanks,
Adam

This patch prevents the PCI<->PCI bridge driver from binding to PCI
express devices. This is needed to coexist with the PCI express root
port driver. Eventually we may want to rework and better integrate
linux PCI express link support, but for now this should work.

The PCI bridge driver now checks if changing bridge_ctrl is necessary.
It also restores the original bridge_ctl settings when finished scanning
for devices. Finally, a pci_bus setup fix is included.

Hi all,
I'm in the process of overhauling some aspects of the PCI subsystem.
This patch series is a rewrite of the PCI probing and detection code.
It creates a well defined PCI bus class API and allows a standard PCI
driver to bind to PCI bridge devices. This results in the following:

Hi Pierre,
The platform bus does not show the actual physical relationship either. For
x86, ACPI is typically needed to determine this. It would be easy to bind to
spawn pnp devices off of an ISA bridge device, attached to the pci bus, but
whether it's the actual physical parent would be very dif
Hi,
This patch adds initial support for driver matching priorities to the
driver model. It is needed for my work on converting the pci bridge
driver to use "struct device_driver". It may also be helpful for driver
with more complex (or long id lists as I've seen in many cases) matching
criteria.
