Merge tag 'pci-v3.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas:
"I'll be on vacation until Aug 11, and I suspect the merge window will
open before then, so I'm sending this to you early. There are more
things I'd like to get into v3.17, so I hope to send another pull
request soon after I return.
The most notable pieces here are:
- Support BARs up to 128GB (up from 8GB)
- Fix SR-IOV resource assignment when we fail to expand a resource
- Rework pciehp to handle a common hardware erratum
- Cleanup MSI
- Fix NIC renaming issue
- Fix VGA default device issue on EFI systems
- Fix ASPM configuration (previously we didn't enable it as expected)
Alex Williamson has graciously agreed to take care of any major issues
with this if you take it before I return.
Details:
Resource management
- Support BAR sizes up to 128GB (Yinghai Lu)
- Keep original resource if we fail to expand it (Guo Chao)
- Return conventional error values from pci_revert_fw_address() (Bjorn Helgaas)
- Tidy resource assignment messages (Bjorn Helgaas)
- Don't exclude low BIOS area for non-PCI cards (Christoph Schulz)
PCI device hotplug
- Prevent NULL dereference during pciehp probe (Andreas Noever)
- Make pciehp pcie_wait_cmd() self-contained (Bjorn Helgaas)
- Wait for pciehp hotplug command completion lazily (Bjorn Helgaas)
- Compute pciehp timeout from hotplug command start time (Bjorn Helgaas)
- Remove pciehp assumptions about which commands cause completion events (Bjorn Helgaas)
- Clear pciehp Data Link Layer State Changed during init (Myron Stowe)
- Remove pciehp struct controller.no_cmd_complete (Rajat Jain)
- Remove cpqphp unnecessary null test (Fabian Frederick)
- Remove "invalid IRQ" warning for hot-added PCIe ports (Jiang Liu)
IOMMU
- Add DMA alias quirk for Intel 82801 bridge (Alex Williamson)
MSI
- Add internal msix_clear_and_set_ctrl() (Yijing Wang)
- Remove unused msi_enabled_mask() (Yijing Wang)
- Cache Multiple Message Capable in struct msi_desc (Yijing Wang)
- Add msi_setup_entry() to clean up initialization (Yijing Wang)
- Remove unused msi_remove_pci_irq_vectors() (Yijing Wang)
- Retrieve first MSI IRQ from msi_desc rather than pci_dev (Yijing Wang)
- Remove unused list access in __pci_restore_msix_state() (Yijing Wang)
- Use irq_get_msi_desc() to simplify code (Yijing Wang)
Generic host bridge driver
- Fix GPL v2 license string typo (Bjorn Helgaas)
Marvell MVEBU
- Fix GPL v2 license string typo (Thierry Reding)
NVIDIA Tegra
- Use correct initial HW settings (Phil Edworthy)
- Remove rcar_pcie_setup_window() resource argument (Phil Edworthy)
- Fix GPL v2 license string typo (Thierry Reding)
Renesas R-Car
- Remove redundant config accessor register checks (Sergei Shtylyov)
- Fix GPL v2 license string typo (Bjorn Helgaas)
Virtualization
- Factor secondary bus reset logic (Gavin Shan)
- Remove duplicate powerpc reset logic (Gavin Shan)
Miscellaneous
- Rework default VGA detection for EFI (Bruno Prémont)
- Fix sysfs "acpi_index" and "label" errors for NIC renaming (Simone Gotti)
- Configure ASPM at pci_enable_device()-time (Vidya Sagar)
- Add include/linux/pci_ids.h include guard (Rasmus Villemoes)"
