PCI: the overdue removal of pci_module_init()

2007-05-03T02:02:38+00:00

Unless we finally completely remove it, people will always add new users.

MSI: Remove dev->first_msi_irq

2007-05-03T02:02:37+00:00

Now that we keep a list of msi descriptors, we don't need first_msi_irq
in the pci dev.

If we somehow have zero MSIs configured list_entry() will give us weird
oopes or nice memory corruption bugs. So be paranoid. Add BUG_ONs and also
a check in pci_msi_check_device() to make sure nvec > 0.

MSI: Use a list instead of the custom link structure

2007-05-03T02:02:37+00:00

The msi descriptors are linked together with what looks a lot like
a linked list, but isn't a struct list_head list. Make it one.

The only complication is that previously we walked a list of irqs, and
got the descriptor for each with get_irq_msi(). Now we have a list of
descriptors and need to get the irq out of it, so it needs to be in the
actual struct msi_desc. We use 0 to indicate no irq is setup.

PCI: Create alloc_pci_dev(), the one true way to create a struct pci_dev

2007-05-03T02:02:37+00:00

There are currently several places in the kernel where we kmalloc()
a struct pci_dev and start initialising it. It'd be preferable to
have an allocator so we can ensure the pci_dev is correctly initialised
in one place.

PCI: define pci_request/release_regions() for CONFIG_PCI=n

2007-05-03T02:02:35+00:00

Balance declarations of pci_request_regions() and pci_release_regions() with
empty inline definitions for the CONFIG_PCI=n case -- otherwise my patch to
drivers/net/3c59x.c in the -mm tree doesn't compile. :-)

pci: New PCI-E reset API

2007-05-03T02:02:34+00:00

Adds a new API which can be used to issue various types
of PCI-E reset, including PCI-E warm reset and PCI-E hot reset.
This is needed for an ipr PCI-E adapter which does not properly
implement BIST. Running BIST on this adapter results in PCI-E
errors. The only reliable reset mechanism that exists on this
hardware is PCI Fundamental reset (warm reset). Since driving
this type of reset is architecture unique, this provides the
necessary hooks for architectures to add this support.

driver core: per-subsystem multithreaded probing

2007-04-27T17:57:28+00:00

Make multithreaded probing work per subsystem instead of per driver.

It doesn't make much sense to probe the same device for multiple drivers in
parallel (after all, only one driver can bind to the device).  Instead, create
a probing thread for each device that probes the drivers one after another. 
Also make the decision to use multi-threaded probe per bus instead of per
device and adapt the pci code.

[PATCH] pci: Repair pci_save/restore_state so we can restore one save many times.

2007-03-12T23:31:50+00:00

Because we do not reserve space for the pci-x and pci-e state in struct
pci dev we need to dynamically allocate it.  However because we need
to support restore being called multiple times after a single save
it is never safe to free the buffers we have allocated to hold the
state.

So this patch modifies the save routines to first check to see
if we have already allocated a state buffer before allocating
a new one.  Then the restore routines are modified to not free
the state after restoring it.  Simple and it fixes some subtle
error path handling bugs, that are hard to test for.
