PCI/MSI: irqchip: Fix PCI_MSI dependencies The PCI_MSI symbol is used inconsistently throughout the tree, with some drivers using 'select' and others using 'depends on', or using conditional selects. This keeps causing problems; the latest one is a result of ARCH_ALPINE using a 'select' statement to enable its platform-specific MSI driver without enabling MSI: warning: (ARCH_ALPINE) selects ALPINE_MSI which has unmet direct dependencies (PCI && PCI_MSI) drivers/irqchip/irq-alpine-msi.c:104:15: error: variable 'alpine_msix_domain_info' has initializer but incomplete type static struct msi_domain_info alpine_msix_domain_info = { ^~~~~~~~~~~~~~~ drivers/irqchip/irq-alpine-msi.c:105:2: error: unknown field 'flags' specified in initializer .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^ drivers/irqchip/irq-alpine-msi.c:105:11: error: 'MSI_FLAG_USE_DEF_DOM_OPS' undeclared here (not in a function) .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^~~~~~~~~~~~~~~~~~~~~~~~ There is little reason to enable PCI support for a platform that uses MSI but then leave MSI disabled at compile time.

NWL PCIe controller. The controller can act as Root Port

support root port enabling.
PCI: faraday: Add Faraday Technology FTPCI100 PCI Host Bridge driver Add a host bridge driver for the Faraday Technology FPPCI100 host bridge, used for Cortina Systems Gemini SoC (SL3516) PCI Host Bridge. This code is inspired by the out-of-tree OpenWRT patch and then extensively rewritten for device tree and using the modern helpers to cut down and modernize the code to all new PCI frameworks. A driver exists in U-Boot as well. Tested on the ITian Square One SQ201 NAS with the following result in the boot log (trimmed to relevant parts): OF: PCI: host bridge /soc/pci@50000000 ranges: OF: PCI: IO 0x50000000..0x500fffff -> 0x00000000 OF: PCI: MEM 0x58000000..0x5fffffff -> 0x58000000 ftpci100 50000000.pci: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [bus 00-ff] pci_bus 0000:00: root bus resource [io 0x0000-0xfffff] pci_bus 0000:00: root bus resource [mem 0x58000000-0x5fffffff] ftpci100 50000000.pci: DMA MEM1 BASE: 0x0000000000000000 -> 0x0000000007ffffff config 00070000 ftpci100 50000000.pci: DMA MEM2 BASE: 0x0000000000000000 -> 0x0000000003ffffff config 00060000 ftpci100 50000000.pci: DMA MEM3 BASE: 0x0000000000000000 -> 0x0000000003ffffff config 00060000 PCI: bus0: Fast back to back transfers disabled pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22 pci 0000:00:0c.0: BAR 0: assigned [mem 0x58000000-0x58007fff] pci 0000:00:09.2: BAR 0: assigned [mem 0x58008000-0x580080ff] pci 0000:00:09.0: BAR 4: assigned [io 0x1000-0x101f] pci 0000:00:09.1: BAR 4: assigned [io 0x1020-0x103f] pci 0000:00:09.0: enabling device (0140 -> 0141) pci 0000:00:09.0: HCRESET not completed yet! pci 0000:00:09.1: enabling device (0140 -> 0141) pci 0000:00:09.1: HCRESET not completed yet! pci 0000:00:09.2: enabling device (0140 -> 0142) rt61pci 0000:00:0c.0: enabling device (0140 -> 0142) ieee80211 phy0: rt2x00_set_chip: Info - Chipset detected - rt: 2561, rf: 0003, rev: 000c ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver ehci-pci: EHCI PCI platform driver ehci-pci 0000:00:09.2: EHCI Host Controller ehci-pci 0000:00:09.2: new USB bus registered, assigned bus number 1 ehci-pci 0000:00:09.2: irq 125, io mem 0x58008000 ehci-pci 0000:00:09.2: USB 2.0 started, EHCI 1.00 hub 1-0:1.0: USB hub found hub 1-0:1.0: 4 ports detected uhci_hcd: USB Universal Host Controller Interface driver uhci_hcd 0000:00:09.0: UHCI Host Controller uhci_hcd 0000:00:09.0: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:09.0: HCRESET not completed yet! uhci_hcd 0000:00:09.0: irq 123, io base 0x00001000 hub 2-0:1.0: USB hub found hub 2-0:1.0: config failed, hub doesn't have any ports!

PCI: v3-semi: Add V3 Semiconductor PCI host driver This PCI host bridge from V3 Semiconductor needs no further introduction. An ancient driver for it has been sitting in arch/arm/mach-integrator/pci_v3.* since before v2.6.12 and the initial migration to git. But we need to get the drivers out of arch/arm/* and get proper handling of the old drivers, rewrite and clean up so the PCI maintainer can control the mass of drivers without having to run all over the kernel. We also switch swiftly to all the new infrastructure found in the PCI hosts as of late. Some code is preserved so I have added an extensive list of authors in the top comment section.

But we need to get the drivers out of arch/arm/* and get proper handling of the old drivers, rewrite and clean up so the PCI maintainer can control the mass of drivers without having to run all over the kernel. We also switch swiftly to all the new infrastructure found in the PCI hosts as of late. Some code is preserved so I have added an extensive list of authors in the top comment section.

PCI: iproc: Add iProc PCIe MSI support Add PCIe MSI support for both PAXB and PAXC interfaces on all iProc-based platforms. The iProc PCIe MSI support deploys an event queue-based implementation. Each event queue is serviced by a GIC interrupt and can support up to 64 MSI vectors. Host memory is allocated for the event queues, and each event queue consists of 64 word-sized entries. MSI data is written to the lower 16-bit of each entry, whereas the upper 16-bit of the entry is reserved for the controller for internal processing. Each event queue is tracked by a head pointer and tail pointer. Head pointer indicates the next entry in the event queue to be processed by the driver and is updated by the driver after processing is done. The controller uses the tail pointer as the next MSI data insertion point. The controller ensures MSI data is flushed to host memory before updating the tail pointer and then triggering the interrupt. MSI IRQ affinity is supported by evenly distributing the interrupts to each CPU core. MSI vector is moved from one GIC interrupt to another in order to steer to the target CPU. Therefore, the actual number of supported MSI vectors is: M * 64 / N where M denotes the number of GIC interrupts (event queues), and N denotes the number of CPU cores. This iProc event queue-based MSI support should not be used with newer platforms with integrated MSI support in the GIC (e.g., giv2m or gicv3-its).

Adds support for the Intel Volume Management Device (VMD). VMD is a
secondary PCI host bridge that allows PCI Express root ports,
and devices attached to them, to be removed from the default
PCI domain and placed within the VMD domain. This provides
more bus resources than are otherwise possible with a
single domain. If you know your system provides one of these and
has devices attached to it, say Y; if you are not sure, say N.
To compile this driver as a module, choose M here: the
module will be called vmd.
