[PATCH] PCI: PCIE power management quirk

2006-07-12T23:05:48+00:00

When changing power states from D0->DX and then from DX->D0, some
Intel PCIE chipsets will cause a device reset to occur.  This will
cause problems for any D State other than D3, since any state
information that the driver will expect to be present coming from
a D1 or D2 state will have been cleared.  This patch addes a
flag to the pci_dev structure to indicate that devices should
not use states D1 or D2, and will set that flag for the affected
chipsets.  This patch also modifies pci_set_power_state() so that
when a device driver tries to set the power state on
a device that is downstream from an affected chipset, or on one
of the affected devices it only allows state changes to or
from D0 & D3.  In addition, this patch allows the delay time
between D3->D0 to be changed via a quirk.  These chipsets also
need additional time to change states beyond the normal 10ms.

[PATCH] PCI: disable msi mode in pci_disable_device

2006-06-21T19:00:00+00:00

Brice said the pci_save_msi_state breaks his driver in his special usage
(not in suspend/resume), as pci_save_msi_state will disable msi mode. In
his usage, pci_save_state will be called at runtime, and later (after
the device operates for some time and has an error) pci_restore_state
will be called.
In another hand, suspend/resume needs disable msi mode, as device should
stop working completely. This patch try to workaround this issue.
Drivers are expected call pci_disable_device in suspend time after
pci_save_state.

[PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundation

2006-06-21T18:59:59+00:00

Currently, the EDAC (error detection and correction) modules that are in
the kernel contain some features that need to be moved. After some good
feedback on the PCI Parity detection code and interface
(http://www.ussg.iu.edu/hypermail/linux/kernel/0603.1/0897.html) this
patch ADDs an new attribute to the pci_dev structure: Namely the
'broken_parity_status' bit.

When set this indicates that the respective hardware generates false
positives of Parity errors.

The EDAC "blacklist" solution was inferior and will be removed in a
future patch.

Also in this patch is a PCI quirk.c entry for an Infiniband PCI-X card
which generates false positive parity errors.

I am requesting comments on this AND on the possibility of a exposing
this 'broken_parity_status' bit to userland via the PCI device sysfs
directory for devices. This access would allow for enabling of this
feature on new devices and for old devices that have their drivers
updated. (SLES 9 SP3 did this on an ATI motherboard video device). There
is a need to update such a PCI attribute between kernel releases.

This patch just adds a storage place for the attribute and a quirk entry
for a known bad PCI device. PCI Parity reaper/harvestor operations are
in EDAC itself and will be refactored to use this PCI attribute instead
of its own mechanisms (which are currently disabled) in the future.

[PATCH] PCI: Add pci_assign_resource_fixed -- allow fixed address assignments

2006-06-21T18:59:59+00:00

PCI: Add pci_assign_resource_fixed -- allow fixed address assignments

On some embedded systems the PCI address for hotplug devices are not only
known a priori but are required to be at a given PCI address for other
master in the system to be able to access.

An example of such a system would be an FPGA which is setup from user space
after the system has booted.  The FPGA may be access by DSPs in the system
and those DSPs expect the FPGA at a fixed PCI address.

Added pci_assign_resource_fixed() as a way to allow assignment of the PCI
devices's BARs at fixed PCI addresses.

[PATCH] Revive pci_find_ext_capability

2006-05-24T04:27:31+00:00

This patch revives pci_find_ext_capability (has been disabled a couple month
ago since it was not used anywhere. See http://lkml.org/lkml/2006/1/20/247).
It will now be used by the myri10ge driver.

[PATCH] PCI: fix sparse warning about pci_bus_flags

2006-04-14T19:25:25+00:00

Sparse warns about casting to a __bitwise type.  However, it's correct
to do when defining the enum for pci_bus_flags_t, so add a __force to
quiet the warnings.  This will fix getting

    include/linux/pci.h:100:26: warning: cast to restricted type

from sparse all over the build.
