The 'power' attribute of the fakephp driver originally only let one turn a
slot off. If one tried to turn a slot on (echo 1 > .../power), it would
return ENODEV, as fakephp did not support this function.
An old (pre-git) patch changed this:
2004/11/11 16:33:31-08:00 jdittmer
[PATCH] fakephp: add pci bus rescan ability
http://article.gmane.org/gmane.linux.kernel/251183
Now writing "1" to the power attribute has the effect of triggering a bus
rescan, but it still returns ENODEV, probably an oversight in the above
patch.
Using the BusyBox echo will not produce an error message, but will
trigger *two* bus rescans (and return an exit code of 1):
~ # strace echo -n 1 > /sys/bus/pci/slots/0000:00:00.0/power
...
write(1, "1", 1) = -1 ENODEV (No such device)
write(1, "1", 1) = -1 ENODEV (No such device)
exit(1) = ?
Using cp gives a write error, even though the write did happen and a rescan
was triggered:
~ # echo -n 1 > tmp ; cp tmp /sys/bus/pci/slots/0000:00:00.0/power
cp: Write Error: No such device
It seems much better to return success instead of failure. The actual
status of the bus rescan is hard to return. It happens asynchronously in a
work thread, so the sysfs store functions returns before any status is
ready (the whole point of the work queue). And even if it didn't do this,
the rescan doesn't have any clear status to return.

This follows up 53a9bf4267. Some newer
CX700 BIOSes from our vendor have PCI Bus Parking disabled but PCI
Master read caching enabled. This creates problems such as system
freezing when both the network controller and the USB controller are
active and one of them is pretty busy (e.g. heavy network traffic).
This patch separates the checks and both the bus parking and the read
caching are disabled independently if either is enabled by the BIOS.

Vital Product Data (VPD) may be exposed by PCI devices in several
ways. It is generally unsafe to read this information through the
existing interfaces to user-land because of stateful interfaces.
This adds:
- abstract operations for VPD access (struct pci_vpd_ops)
- VPD state information in struct pci_dev (struct pci_vpd)
- an implementation of the VPD access method specified in PCI 2.2
(in access.c)
- a 'vpd' binary file in sysfs directories for PCI devices with VPD
operations defined
It adds a probe for PCI 2.2 VPD in pci_scan_device() and release of
VPD state in pci_release_dev().

This patch is for batching up the flushing of the IOTLB for the DMAR
implementation found in the Intel VT-d hardware. It works by building a list
of to be flushed IOTLB entries and a bitmap list of which DMAR engine they are
from.
After either a high water mark (250 accessible via debugfs) or 10ms the list
of iova's will be reclaimed and the DMAR engines associated are IOTLB-flushed.
This approach recovers 15 to 20% of the performance lost when using the IOMMU
for my netperf udp stream benchmark with small packets. It can be disabled
with a kernel boot parameter "intel_iommu=strict".
Its use does weaken the IOMMU protections a bit.

use this generic version instead.
This version is based on powerpc, which seemed most up-to-date. The only

PCI Express ASPM defines a protocol for PCI Express components in the D0
state to reduce Link power by placing their Links into a low power state
and instructing the other end of the Link to do likewise. This
capability allows hardware-autonomous, dynamic Link power reduction
beyond what is achievable by software-only controlled power management.
However, The device should be configured by software appropriately.
Enabling ASPM will save power, but will introduce device latency.
This patch adds ASPM support in Linux. It introduces a global policy for
ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control
it. The interface can be used as a boot option too. Currently we have
below setting:
-default, BIOS default setting
-powersave, highest power saving mode, enable all available ASPM
state and clock power management
-performance, highest performance, disable ASPM and clock power
management
By default, the 'default' policy is used currently.
In my test, power difference between powersave mode and performance mode
is about 1.3w in a system with 3 PCIE links.
Note: some devices might not work well with aspm, either because chipset
issue or device issue. The patch provide API (pci_disable_link_state),
driver can disable ASPM for specific device.

The HP Compaq nc6120 has the same PCI sub-device ID as the nx6110, and the
SMBus is used by ACPI for thermal management on the nc6120, so Linux should
not attach a native driver to it. This means that this quirk is unsafe and
has to be removed.
I also added a comment to help developers realize that adding new IDs to this

particular only after checking that ACPI is not making use of the SMBus.

I have a fix for the ThinkPad docking Oops but if the issue being
discussed here is caused by the transparent bridge sizing removal
change I totally agree that it should be reverted."
The transparent bridge sizing removal change was motivated by
insufficient PCI memory resource for a transparent bridge window that
was being created as a result of expansion ROM(s) being included in
the transparent bridge sizing calculations.
A later "PCI: Remove default PCI expansion ROM memory allocation"
change ( re: http://lkml.org/lkml/2007/12/11/361 ) removes the
expansion ROM(s) from the transparent bridge sizing calculations which
actually resolves the original issue in a different manner. So, even
if the "PCI: remove transparent bridge sizing" is not problematic it
is no longer needed anyway."

In drivers/pci/hotplug/ibmphp_ebda.c::ebda_rsrc_controller(), storage is
allocated with kzalloc() and assigned to 'tmp_slot'. Then lots of
stuff, like ->flag, ->supported_speed etc is set in tmp_slot. A bit
further down there's then this test :
if (!bus_info_ptr1) {
rc = -ENODEV;
goto error;
}
At this point, tmp_slot has not been assigned to anything, so when
erroring-out we want to free it, but nothing at the 'error:' label
free's 'tmp_slot' - and we can't really free 'tmp_slot' at 'error:'
since we may jump to that label later when 'tmp_slot' *has* been used
and we do not want it freed. So, the only sane option left seems to be
to kfree(tmp_slot) just before jumping to the 'error:' label in the one
place where this is what actually makes sense. The following patch does
just that and thus kills off a tiny potential memory leak.

During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.
But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.
For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.
These changes are necessary to fix a hibernation regression related

- Repeating hot-add/hot-remove of pci adapter card increases files

# ls
