PCI: revert "pcie: utilize pcie transaction pending bit"

2008-03-25T05:38:44+00:00

Revert as it is reported to cause problems for people.

    pcie: utilize pcie transaction pending bit

    PCIE has a mechanism to wait for Non-Posted request to complete. I think
    pci_disable_device is a good place to do this.

devres: implement pcim_iomap_regions_request_all()

2008-03-17T12:26:44+00:00

Some drivers need to reserve all PCI BARs to prevent other drivers
misusing unoccupied BARs.  pcim_iomap_regions_request_all() requests
all BARs and iomap specified BARs.

PCI: fix issue with busses registering multiple times in sysfs

2008-03-13T17:21:09+00:00

PCI busses can be registered multiple times, so we need to detect if we
have registered our bus structure in sysfs already.  If so, don't do it
again.

Thanks to Guennadi Liakhovetski  for reporting
the problem, and to Linus for poking me to get me to believe that it was
a real problem.

rename DECLARE_PCI_DEVICE_TABLE to DEFINE_PCI_DEVICE_TABLE

2008-03-11T01:01:17+00:00

This macro is used to define tables, not to declare them.

PCI: Add DECLARE_PCI_DEVICE_TABLE macro

2008-03-04T23:07:04+00:00

The definitions of struct pci_device_id arrays should generally follow
the same pattern across the entire kernel.  This macro defines this
array as const and puts it into the __devinitconst section.

There are currently many definitions scattered about the kernel that
omit the __devinitdata modifier despite the documentation stating that
it should always be there.  These definitions really also should have
been const, which wasn't possible before but has become so with the
addition of the __devinitconst attribute.

Furthermore, there are definitions that use "const" and __devinitdata,
which is explicitly wrong but the compiler doesn't catch section
mismatches if there's only one such one case in the module (which is
often the case).

Adding the __devinitconst modifier where there was nothing before buys
us memory.  Adding the const modifier gives the compiler a chance to do
its thing.  Changing __devinitdata to __devinitconst where it was wrong
actually fixes some compiler errors in older (mid-release) kernels that
were patched over by "removing" the section attribute altogether (which
wastes memory).

This macro makes it pretty difficult to get this definition wrong in
the future...

Change pci_raw_ops to pci_raw_read/write

2008-02-10T20:52:46+00:00

We want to allow different implementations of pci_raw_ops for standard
and extended config space on x86.  Rather than clutter generic code with
knowledge of this, we make pci_raw_ops private to x86 and use it to
implement the new raw interface -- raw_pci_read() and raw_pci_write().

iommu sg merging: PCI: add dma segment boundary support

2008-02-05T17:44:12+00:00

This adds PCI's accessor for segment_boundary_mask in device_dma_parameters.

The default segment_boundary is set to 0xffffffff, same to the block layer's
default value (and the scsi mid layer uses the same value).

iommu sg merging: PCI: add device_dma_parameters support

2008-02-05T17:44:10+00:00

This adds struct device_dma_parameters in struct pci_dev and properly
sets up a pointer in struct device.

The default max_segment_size is set to 64K, same to the block layer's
default value.

Revert "PCI: PCIE ASPM support"

2008-02-02T19:32:01+00:00

This reverts commit 6c723d5bd89f03fc3ef627d50f89ade054d2ee3b.

It caused build errors on non-x86 platforms, config file confusion, and
even some boot errors on some x86-64 boxes.  All around, not quite ready
for prime-time :(

PCI: make pci_bus a struct device

2008-02-01T23:04:31+00:00

This moves the pci_bus class device to be a real struct device and at
the same time, place it in the device tree in the correct location.

Note, the old "bridge" symlink is now gone, but this was a non-standard
link and no userspace program used it.  If you need to determine the
device that the bus is on, follow the standard device symlink, or walk
up the device tree.
