The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now responsible for allocating and freeing the linux irq in addition to setting up the the linux irq to work with the interrupt. arch_setup_msi_irq now takes a pci_device and a msi_desc and returns an irq. With this change in place this code should be useable by all platforms except those that won't let the OS touch the hardware like ppc RTAS. Signed-off-by:

We need to be able to get from an irq number to a struct msi_desc. The msi_desc array in msi.c had several short comings the big one was that it could not be used outside of msi.c. Using irq_data in struct irq_desc almost worked except on some architectures irq_data needs to be used for something else. So this patch adds a msi_desc pointer to irq_desc, adds the appropriate wrappers and changes all of the msi code to use them. The dynamic_irq_init/cleanup code was tweaked to ensure the new field is left in a well defined state. Signed-off-by:

Since msi_remove_pci_irq_vectors is designed to be called during hotplug remove it is actively wrong to query the hardware and expect meaningful results back. To that end remove the pci_find_capability calls. Testing dev->msi_enabled and dev->msix_enabled gives us all of the information we need. Signed-off-by:

With the removal of msi_lookup_irq all of the functions using msi_lock operated on a single device and none of them could reasonably be called on that device at the same time. Since what little synchronization that needs to happen needs to happen outside of the msi functions, msi_lock could never be contended and as such is useless and just complicates the code.

The function msi_lookup_irq was horrible. As a side effect of running it changed dev->irq, and then the callers would need to change it back. In addition it does a global scan through all of the irqs, which seems to be the sole justification of the msi_lock. To remove the neede for msi_lookup_irq I added first_msi_irq to struct pci_dev. Then depending on the context I replaced msi_lookup_irq with dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled. msi_enabled and msix_enabled were already present in pci_dev for other reasons.

The PCI save/restore code doesn't need to care about MSI vs MSI-X, all it really wants is to say "save/restore all MSI(-X) info for this device". This is borne out in the code, we call the MSI and MSI-X save routines side by side, and similarly with the restore routines. So combine the MSI/MSI-X routines into pci_save_msi_state() and pci_restore_msi_state(). It is up to those routines to decide what state needs to be saved. Signed-off-by:

I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature. Signed-off-by:

Speed up the Intel SMBus PCI quirk by avoiding tests which can only fail. This also makes the compiled code significantly smaller when using gcc 3.2/3.4. gcc 4.x appears to optimize the code by itself so this change doesn't make a difference there. Signed-off-by:

There's an existing quirk for the kernel to use 1k IO space granularity on the Intel P64H2. It turns out however that pci_setup_bridge() in drivers/pci/setup-bus.c reads in the IO base and limit address register masks it off to the nearest 4k, and writes it back. This causes the kernel to be on 1k boundaries and the hardware to be 4k aligned. The patch below fixes the problem. Signed-off-by:

This patch adds the following changes into generic PCI code especially for PCI legacy I/O port free drivers. - Added new pci_request_selected_regions() and pci_release_selected_regions() for PCI legacy I/O port free drivers in order to request/release only the selected regions. - Added helper routine pci_select_bars() which makes proper mask of BARs from the specified resource type. This would be very helpful for users of pci_enable_device_bars(). Signed-off-by:Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Cc: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by:
