[GIT PULL] PCI changes for v4.17
From: Bjorn Helgaas
Date: Fri Apr 06 2018 - 15:02:11 EST
PCI changes:
- move pci_uevent_ers() out of pci.h (Michael Ellerman)
- skip ASPM common clock warning if BIOS already configured it (Sinan
Kaya)
- fix ASPM Coverity warning about threshold_ns (Gustavo A. R. Silva)
- remove last user of pci_get_bus_and_slot() and the function itself
(Sinan Kaya)
- add decoding for 16 GT/s link speed (Jay Fang)
- add interfaces to get max link speed and width (Tal Gilboa)
- add pcie_bandwidth_capable() to compute max supported link bandwidth
(Tal Gilboa)
- add pcie_bandwidth_available() to compute bandwidth available to device
(Tal Gilboa)
- add pcie_print_link_status() to log link speed and whether it's limited
(Tal Gilboa)
- use PCI core interfaces to report when device performance may be
limited by its slot instead of doing it in each driver (Tal Gilboa)
- fix possible cpqphp NULL pointer dereference (Shawn Lin)
- rescan more of the hierarchy on ACPI hotplug to fix Thunderbolt/xHCI
hotplug (Mika Westerberg)
- add support for PCI I/O port space that's neither directly accessible
via CPU in/out instructions nor directly mapped into CPU physical
memory space. This is fairly intrusive and includes minor changes to
interfaces used for I/O space on most platforms (Zhichang Yuan, John
Garry)
- add support for HiSilicon Hip06/Hip07 LPC I/O space (Zhichang Yuan,
John Garry)
- use PCI_EXP_DEVCTL2_COMP_TIMEOUT in rapidio/tsi721 (Bjorn Helgaas)

- report quirks that take longer than 10ms (Bjorn Helgaas)
- add and use Altera Vendor ID (Johannes Thumshirn)
- tidy Makefiles and comments (Bjorn Helgaas)
- don't set up INTx if MSI or MSI-X is enabled to align cris, frv, ia64,
and mn10300 with x86 (Bjorn Helgaas)
- move pcieport_if.h to drivers/pci/pcie/ to encapsulate it (Frederick
Lawler)
- merge pcieport_if.h into portdrv.h (Bjorn Helgaas)
- move workaround for BIOS PME issue from portdrv to PCI core (Bjorn
Helgaas)
- completely disable portdrv with "pcie_ports=compat" (Bjorn Helgaas)
- remove portdrv link order dependency (Bjorn Helgaas)
- remove support for unused VC portdrv service (Bjorn Helgaas)
- simplify portdrv feature permission checking (Bjorn Helgaas)
- remove "pcie_hp=nomsi" parameter (use "pci=nomsi" instead) (Bjorn
Helgaas)
- remove unnecessary "pcie_ports=auto" parameter (Bjorn Helgaas)
- use cached AER capability offset (Frederick Lawler)
- don't enable DPC if BIOS hasn't granted AER control (Mika Westerberg)
- rename pcie-dpc.c to dpc.c (Bjorn Helgaas)
- use generic pci_mmap_resource_range() instead of powerpc and xtensa
arch-specific versions (David Woodhouse)
- support arbitrary PCI host bridge offsets on sparc (Yinghai Lu)
- remove System and Video ROM reservations on sparc (Bjorn Helgaas)
- probe for device reset support during enumeration instead of runtime
(Bjorn Helgaas)
- add ACS quirk for Ampere (née APM) root ports (Feng Kan)
- add function 1 DMA alias quirk for Marvell 88SE9220 (Thomas
Vincent-Cross)
- protect device restore with device lock (Sinan Kaya)

Ahmed)
- consolidate VPD code in vpd.c (Bjorn Helgaas)
- add Tegra dependency on PCI_MSI_IRQ_DOMAIN (Arnd Bergmann)
- add DT support for R-Car r8a7743 (Biju Das)
- fix a PCI_EJECT vs PCI_BUS_RELATIONS race condition in Hyper-V host
bridge driver that causes a general protection fault (Dexuan Cui)
- fix Hyper-V host bridge hang in MSI setup on 1-vCPU VMs with SR-IOV
(Dexuan Cui)
- fix Hyper-V host bridge hang when ejecting a VF before setting up MSI
(Dexuan Cui)
- make several structures static (Fengguang Wu)
- increase number of MSI IRQs supported by Synopsys DesignWare bridges
from 32 to 256 (Gustavo Pimentel)
- implemented multiplexed IRQ domain API and remove obsolete MSI IRQ API
from DesignWare drivers (Gustavo Pimentel)
- add Tegra power management support (Manikanta Maddireddy)
- add Tegra loadable module support (Manikanta Maddireddy)
- handle 64-bit BARs correctly in endpoint support (Niklas Cassel)
- support optional regulator for HiSilicon STB (Shawn Guo)
- use regulator bulk API for Qualcomm apq8064 (Srinivas Kandagatla)
- support power supplies for Qualcomm msm8996 (Srinivas Kandagatla)
You should see these merge conflicts:
1) Conflicts in:
drivers/pci/quirks.c
drivers/pci/vpd.c
from these commits:
7dcf688d4c78 ("PCI/cxgb4: Extend T3 PCI quirk to T4+ devices")
996058573b22 ("PCI/VPD: Move VPD quirks to vpd.c")
The body of the quirk updated by 7dcf688d4c78 needs to move to vpd.c.
2) Conflicts in:
drivers/net/ethernet/mellanox/mlx5/core/en_main.c
from these commits:
0608d4dbaf4e ("net/mlx5e: Unify slow PCI heuristic")
33523a361307 ("net/mlx5e: Use pcie_bandwidth_available() to compute bandwidth")
0608d4dbaf4e moved usage of mlx5e_get_pci_bw(), and 33523a361307
replaced that usage with pcie_bandwidth_available().
