* PCI MSI: Refactor interrupt masking codeMatthew Wilcox2009-03-20
| | | | | | | | | | | | | | | | | | Since most of the callers already know whether they have an MSI or an MSI-X capability, split msi_set_mask_bits() into msi_mask_irq() and msix_mask_irq(). The only callers which don't (mask_msi_irq() and unmask_msi_irq()) can share code in msi_set_mask_bit(). This then becomes the only caller of msix_flush_writes(), so we can inline it. The flushing read can be to any address that belongs to the device, so we can eliminate the calculation too. We can also get rid of maskbits_mask from struct msi_desc and simply recalculate it on the rare occasion that we need it. The single-bit 'masked' element is replaced by a copy of the 32-bit 'masked' register, so this patch does not affect the size of msi_desc.

* PCI MSI: msi_desc->dev is always initialisedMatthew Wilcox2009-03-20
| | | | | | | | | By passing the pci_dev into alloc_msi_entry() we can be sure that the ->dev entry is always assigned and so we don't need to check it. Also, we used kzalloc() so we don't need to initialise ->irq to 0. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
* PCI MSI: Replace 'type' with 'is_msix'Matthew Wilcox2009-03-20
| | | | | | | | | | By changing from a 5-bit field to a 1-bit field, we free up some bits that can be used by a later patch. Also rearrange the fields for better packing on 64-bit platforms (reducing the size of msi_desc from 72 bytes to 64 bytes).

| | | | | | | | | | | | | This adds a remove_id sysfs entry to allow users of new_id to later remove the added dynid. One use case is management tools that want to dynamically bind/unbind devices to pci-stub driver while devices are assigned to KVM guests.

* PCI/alpha: pci sysfs resourcesIvan Kokshaysky2009-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This closes http://bugzilla.kernel.org/show_bug.cgi?id=10893 which is a showstopper for X development on alpha. The generic HAVE_PCI_MMAP code (drivers/pci-sysfs.c) is not very useful since we have to deal with three different types of MMIO address spaces: sparse and dense mappings for old ev4/ev5 machines and "normal" 1:1 MMIO space (bwx) for ev56 and later. Also "write combine" mappings are meaningless on alpha - roughly speaking, alpha does write combining, IO reordering and other optimizations by default, unless user splits IO accesses with memory barriers. I think the cleanest way to deal with resource files on alpha is to convert the default no-op pci_create_resource_files() and pci_remove_resource_files() for !HAVE_PCI_MMAP case into __weak functions and override them with alpha specific ones. Another alpha hook is needed for "legacy_" resource files to handle sparse addressing (pci_adjust_legacy_attr). With the "standard" resourceN files on ev56/ev6 libpciaccess works "out of the box". Handling of resourceN_sparse/resourceN_dense files on older machines obviously requires some userland work. Sparse/dense stuff has been tested on sx164 (pca56/pyxis, normally uses bwx IO) with the kernel hacked into "cia compatible" mode.

* PCI/MSI: Allow arch code to return the number of MSI-X availableMichael Ellerman2009-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | There is code in msix_capability_init() which, when the requested number of MSI-X couldn't be allocated, calculates how many MSI-X /could/ be allocated and returns that to the driver. That allows the driver to then make a second request, with a number of MSIs that should succeed. The current code requires the arch code to setup as many msi_descs as it can, and then return to the generic code. On some platforms the arch code may already know how many MSI-X it can allocate, before it sets up any of the msi_descs. So change the logic such that if the arch code returns a positive error code, that is taken to be the number of MSI-X that could be allocated. If the error code is negative we still calculate the number available using the old method. Because it's a little subtle, make sure the error return code from arch_setup_msi_irq() is always negative. That way only implementations of arch_setup_msi_irqs() need to be careful about returning a positive error code.

Because of this, there is no way to detect those events on empty slots in the current pciehp implementation.

| | | | | | | | | | | | | | | | | | | | | | If MSI-X interrupt mode is used by the PCI Express port driver, too many vectors are allocated and it is not ensured that the right vectors will be used for the right services. Namely, the PCI Express specification states that both PCI Express native PME and PCI Express hotplug will always use the same MSI or MSI-X message for signalling interrupts, which implies that the same vector will be used by both of them. Also, the VC service does not use interrupts at all. Moreover, is not clear which of the vectors allocated by pci_enable_msix() in the current code will be used for PME and hotplug and which of them will be used for AER if all of these services are configured. For these reasons, rework the allocation of interrupts for PCI Express ports so that if MSI-X are enabled, the right vectors will be used for the right purposes. Signed-off-by: Rafael J.

Also, both existing port service drivers (AER and PCIe HP) don't even use the vendor and device fields for device matching.

This patch is absolutely trivial, as the integrated USB-IDE bridge is already identified to be an "unusual" device, only the bcdDevice is different (lower) to the bcdDeviceMin already included in the kernel. It is a Prolific 2507 bridge.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic cdc-acm driver is now the best one to handle Sony Ericsson F3507g-based devices (which the Dell 5530 is a rebrand of), now that all the pieces are in place (ie, cac477e8f1038c41b6f29d3161ce351462ef3df7). Removing the IDs from option allows cdc-acm to handle the device. Signed-off-by: Dan Williams <dcbw@redhat.com> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
