[PATCH] PCI Error Recovery: header file patch

2006-01-09T20:13:21+00:00

Various PCI bus errors can be signaled by newer PCI controllers.
Recovering from those errors requires an infrastructure to notify
affected device drivers of the error, and a way of walking through a
reset sequence.  This patch adds a set of callbacks to be used by error
recovery routines to notify device drivers of the various stages of
recovery.

[PATCH] PCI: Export pci_cfg_space_size

2006-01-09T20:13:19+00:00

The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).

[PATCH] pci: store PCI_INTERRUPT_PIN in pci_dev

2006-01-09T20:13:13+00:00

Store the value of the INTERRUPT_PIN in the pci_dev structure
so that it can be retrieved later.

[PATCH] PCI: automatically set device_driver.owner

2005-11-11T00:09:16+00:00

A nice feature of sysfs is that it can create the symlink from the
driver to the module that is contained in it.

It requires that the device_driver.owner is set, what is not the
case for many PCI drivers.

This patch allows pci_register_driver to set automatically the
device_driver.owner for any PCI driver.

Credits to Al Viro who suggested the method.

[PATCH] PCI: add pci_find_next_capability()

2005-11-11T00:09:14+00:00

Some devices have more than one capability of the same type.  For
example, the PCI header for the PathScale InfiniPath looks like:

	04:01.0 InfiniBand: Unknown device 1fc1:000d (rev 02)
		Subsystem: Unknown device 1fc1:000d
		Flags: bus master, fast devsel, latency 0, IRQ 193
		Memory at fea00000 (64-bit, non-prefetchable) [size=2M]
		Capabilities: [c0] HyperTransport: Slave or Primary Interface
		Capabilities: [f8] HyperTransport: Interrupt Discovery and Configuration

There are _two_ HyperTransport capabilities, and the PathScale driver
wants to look at both of them.

The current pci_find_capability() API doesn't work for this, since it
only allows us to get to the first capability of a given type.  The
patch below introduces a new pci_find_next_capability(), which can be
used in a loop like

	for (pos = pci_find_capability(pdev, );
	     pos;
	     pos = pci_find_next_capability(pdev, pos, )) {
		/* ... */
	}

[PATCH] PCI: Block config access during BIST

2005-10-28T22:36:58+00:00

Some PCI adapters (eg.  ipr scsi adapters) have an exposure today in that they
issue BIST to the adapter to reset the card.  If, during the time it takes to
complete BIST, userspace attempts to access PCI config space, the host bus
bridge will master abort the access since the ipr adapter does not respond on
the PCI bus for a brief period of time when running BIST.  On PPC64 hardware,
this master abort results in the host PCI bridge isolating that PCI device
from the rest of the system, making the device unusable until Linux is
rebooted.  This patch is an attempt to close that exposure by introducing some
blocking code in the PCI code.  When blocked, writes will be humored and reads
will return the cached value.  Ben Herrenschmidt has also mentioned that he
plans to use this in PPC power management.

Remove "must_check" attributes in PCI-land

2005-09-09T22:43:46+00:00

Don't just irritate all other kernel developers.  Fix the users first,
then you can re-introduce the must-check infrastructure to avoid new
cases creeping in.
