PCI/AER: Remove unused .link_reset() callback
No hardware seems to actually call .link_reset(), and no driver implements it as more than a nop stub. Drop mentions of the callback from everywhere. It's dropped from the documentation as well, but the doc really needs to be updated to reflect reality better (e.g., on PCIe, slot reset is the link reset). This will be done in a later patch.

Pull PCI updates from Bjorn Helgaas:
"PCI changes:
- add support for PCI on ARM64 boxes with ACPI. We already had this
for theoretical spec-compliant hardware; now we're adding quirks
for the actual hardware (Cavium, HiSilicon, Qualcomm, X-Gene)
- add runtime PM support for hotplug ports
- enable runtime suspend for Intel UHCI that uses platform-specific
wakeup signaling
- add yet another host bridge registration interface. We hope this is
extensible enough to subsume the others
- expose device revision in sysfs for DRM
- to avoid device conflicts, make sure any VF BAR updates are done
before enabling the VF
- avoid unnecessary link retrains for ASPM
- allow INTx masking on Mellanox devices that support it
- allow access to non-standard VPD for Chelsio devices
- update Broadcom iProc support for PAXB v2, PAXC v2, inbound DMA,
etc

PCI: Add pci_register_host_bridge() interface
Make the existing pci_host_bridge structure a proper device that is usable by PCI host drivers in a more standard way. In addition to the existing pci_scan_bus(), pci_scan_root_bus(), pci_scan_root_bus_msi(), and pci_create_root_bus() interfaces, this unfortunately means having to add yet another interface doing basically the same thing, and add some extra code in the initial step. However, this time it's more likely to be extensible enough that we won't have to do another one again in the future, and we should be able to reduce code much more as a result. The main idea is to pull the allocation of 'struct pci_host_bridge' out of the registration, and let individual host drivers and architecture code fill the members before calling the registration function. There are a number of things we can do based on this: * Use a single memory allocation for the driver-specific structure and the generic PCI host bridge * consolidate the contents of driver-specific structures by moving them into pci_host_bridge * Add a consistent interface for removing a PCI host bridge again when unloading a host driver module * Replace the architecture specific __weak pcibios_*() functions with callbacks in a pci_host_bridge device * Move common boilerplate code from host drivers into the generic function, based on contents of the structure * Extend pci_host_bridge with additional members when needed without having to add arguments to pci_scan_*(). * Move members of struct pci_bus into pci_host_bridge to avoid having lots of identical copies.

PCI/MSI: Provide pci_alloc_irq_vectors_affinity()
This is a variant of pci_alloc_irq_vectors() that allows passing a struct irq_affinity to provide fine-grained IRQ affinity control. For now this means being able to exclude vectors at the beginning or end of the MSI vector space, but it could also be used for any other quirks needed in the future (e.g. more vectors than CPUs, or excluding CPUs from the spreading).

Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:
"The irq departement proudly presents:
- A rework of the core infrastructure to optimally spread interrupt
for multiqueue devices. The first version was a bit naive and
failed to take thread siblings and other details into account.
Developed in cooperation with Christoph and Keith.
- Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
active then no further softirq processsing on interrupt return
happens. Otherwise we try to delegate and still run another batch
of network packets in the irq return path, which then tries to
delegate to ksoftirqd .....
- A proper machine parseable sysfs based alternative for
/proc/interrupts.
- ACPI support for the GICV3-ITS and ARM interrupt remapping
- Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC
- A new irq chip for the JCore (SuperH)
- The usual pile of small fixlets in core and irqchip drivers"

PCI: pciehp: Allow exclusive userspace control of indicators
PCIe hotplug supports optional Attention and Power Indicators, which are used internally by pciehp. Users can't control the Power Indicator, but they can control the Attention Indicator by writing to a sysfs "attention" file. The Slot Control register has two bits for each indicator, and the PCIe spec defines the encodings for each as (Reserved/On/Blinking/Off). For sysfs "attention" writes, pciehp_set_attention_status() maps into these encodings, so the only useful write values are 0 (Off), 1 (On), and 2 (Blinking). However, some platforms use all four bits for platform-specific indicators, and they need to allow direct user control of them while preventing pciehp from using them at all. Add a "hotplug_user_indicators" flag to the pci_dev structure. When set, pciehp does not use either the Attention Indicator or the Power Indicator, and the low four bits (values 0x0 - 0xf) of sysfs "attention" write values are written directly to the Attention Indicator Control and Power Indicator Control fields.

PCI: Add PTM clock granularity information
The PTM Control register (PCIe r3.1, sec 7.32.3) contains an Effective Granularity field: This provides information relating to the expected accuracy of the PTM clock, but does not otherwise affect the PTM mechanism. Set the Effective Granularity based on the PTM Root and any intervening PTM Time Sources. This does not set Effective Granularity for Root Complex Integrated Endpoints because I don't know how to figure out clock granularity for them. The spec says: ... system software must set [Effective Granularity] to the value reported in the Local Clock Granularity field by the associated PTM Time Source. but I don't know how to identify the associated PTM Time Source. Normally it's the upstream bridge, but an integrated endpoint has no upstream bridge. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PCI: Use positive flags in pci_alloc_irq_vectors()
Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of certain interrupt types, pass positive flags like PCI_IRQ_LEGACY, PCI_IRQ_MSI, etc., to specify the acceptable interrupt types. This is based on a number of pending driver conversions that just happend to be a whole more obvious to read this way, and given that we have no users in the tree yet it can still easily be done. I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting all interrupt types very simple.

PCI: Allow additional bus numbers for hotplug bridges
A user may hot add a switch requiring more than one bus to enumerate. This previously required a system reboot if BIOS did not sufficiently pad the bus resource, which they frequently don't do. Add a kernel parameter so a user can specify the minimum number of bus numbers to reserve for a hotplug bridge's subordinate buses so rebooting won't be necessary. The default is 1, which is equivalent to previous behavior. Signed-off-by: Keith Busch <keith.busch@intel.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PCI: Spread interrupt vectors in pci_alloc_irq_vectors()
Set the affinity_mask in the PCI device before allocating vectors so that the affinity can be propagated through the MSI descriptor structures to the core IRQ code. To facilitate this, new __pci_enable_msi_range() and __pci_enable_msix_range() helpers are factored out of their not prefixed variants which assigning the new IRQ affinity mask in the PCI device so that the low-level interrupt code can perform the interrupt affinity assignment and do node-local allocations. A new PCI_IRQ_NOAFFINITY flag is added to pci_alloc_irq_vectors() so that this function can also be used by drivers that don't wish to use the automatic affinity assignment.

PCI: Add pcibios_setup_bridge()
Currently, PowerPC PowerNV platform utilizes ppc_md.pcibios_fixup(), which is called for once after PCI probing and resource assignment are completed, to allocate platform required resources for PCI devices: PE#, IO and MMIO mapping, DMA address translation (TCE) table etc. Obviously, it's not hotplug friendly. This adds weak function pcibios_setup_bridge(), which is called by pci_setup_bridge(). PowerPC PowerNV platform will reuse the function to assign above platform required resources to newly plugged PCI devices during PCI hotplug in subsequent patches.

PCI: Put PCIe ports into D3 during suspend
Currently the Linux PCI core does not touch power state of PCI bridges and
PCIe ports when system suspend is entered. Leaving them in D0 consumes
power unnecessarily and may prevent the CPU from entering deeper C-states.
With recent PCIe hardware we can power down the ports to save power given
that we take into account few restrictions:
- The PCIe port hardware is recent enough, starting from 2015.
- Devices connected to PCIe ports are effectively in D3cold once the port
is transitioned to D3 (the config space is not accessible anymore and
the link may be powered down).
- Devices behind the PCIe port need to be allowed to transition to D3cold
and back. There is a way both drivers and userspace can forbid this.
- If the device behind the PCIe port is capable of waking the system it
needs to be able to do so from D3cold.
This patch adds a new flag to struct pci_device called 'bridge_d3'. This
flag is set and cleared by the PCI core whenever there is a change in power
management state of any of the devices behind the PCIe port. When system
later on is suspended we only need to check this flag and if it is true
transition the port to D3 otherwise we leave it in D0.
Also provide override mechanism via command line parameter
"pcie_port_pm=[off|force]" that can be used to disable or enable the
feature regardless of the BIOS manufacturing date.

PCI/ACPI: Add generic MCFG table handling

PCI, of: Move PCI I/O space management to PCI core code
No functional changes in this patch. PCI I/O space mapping code does not depend on OF; therefore it can be moved to PCI core code. This way we will be able to use it, e.g., in ACPI PCI code.

PCI: Reverse standard ACS vs device-specific ACS enabling
The original thought was that if a device implemented ACS, then surely we want to use that... well, it turns out that devices can make an ACS capability so broken that we still need to fall back to quirks. Reverse the order of ACS enabling to give quirks first shot at it. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PCI: Add support for multiple DMA aliases
Solve IOMMU support issues with PCIe non-transparent bridges that use Requester ID look-up tables (RID-LUT), e.g., the PEX8733. The NTB connects devices in two independent PCI domains. Devices separated by the NTB are not able to discover each other. A PCI packet being forwared from one domain to another has to have its RID modified so it appears on correct bus and completions are forwarded back to the original domain through the NTB. The RID is translated using a preprogrammed table (LUT) and the PCI packet propagates upstream away from the NTB. If the destination system has IOMMU enabled, the packet will be discarded because the new RID is unknown to the IOMMU. Adding a DMA alias for the new RID allows IOMMU to properly recognize the packet. Each device behind the NTB has a unique RID assigned in the RID-LUT. The current DMA alias implementation supports only a single alias, so it's not possible to support mutiple devices behind the NTB when IOMMU is enabled. Enable all possible aliases on a given bus (256) that are stored in a bitset. Alias devfn is directly translated to a bit number. The bitset is not allocated for devices that have no need for DMA aliases.

PCI/IOV: Rename and export virtfn_{add, remove}
During EEH recovery, hotplug is applied to the devices which don't
have drivers or their drivers don't support EEH. However, the hotplug,
which was implemented based on PCI bus, can't be applied to VF directly.
Instead, we unplug and plug individual PCI devices (VFs).
This renames virtn_{add,remove}() and exports them so they can be used
in PCI hotplug during EEH recovery.

PCI: Add pci_ops.{add,remove}_bus() callbacks
Add pci_ops.{add,remove}_bus() callbacks, which will be called on every
newly created bus and when a bus is being removed, respectively. This can
be used by drivers to implement driver-specific initialization and teardown
of the bus, in addition to the architecture-specifics implemented by the
pcibios_add_bus() and the pcibios_remove_bus() functions.

PCI: Consolidate PCI DMA constants and interfaces in linux/pci-dma-compat.h
Christoph added a generic include/linux/pci-dma-compat.h, so now there's
one place with most of the PCI DMA interfaces. Move more PCI DMA-related
things there:
- The PCI_DMA_* direction constants from linux/pci.h
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
CONFIG_PCI implementations from drivers/pci/pci.c
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()

PCI: Move pci_dma_* helpers to common code
For a long time all architectures implement the pci_dma_* functions using the generic DMA API, and they all use the same header to do so. Move this header, pci-dma-compat.h, to include/linux and include it from the generic pci.h instead of having each arch duplicate this include.

PCI: Disable IO/MEM decoding for devices with non-compliant BARs
The PCI config header (first 64 bytes of each device's config space) is defined by the PCI spec so generic software can identify the device and manage its usage of I/O, memory, and IRQ resources. Some non-spec-compliant devices put registers other than BARs where the BARs should be. When the PCI core sizes these "BARs", the reads and writes it does may have unwanted side effects, and the "BAR" may appear to describe non-sensical address space. Add a flag bit to mark non-compliant devices so we don't touch their BARs. Turn off IO/MEM decoding to prevent the devices from consuming address space, since we can't read the BARs to find out what that address space would be.

PCI: Update VPD definitions
The 'end' tag is actually 0x0f; it's the representation as a small resource data type tag that's 0x78 (i.e., shifted by 3). Correct PCI_VPD_STIN_END and PCI_VPD_SRDT_END accordingly. Also, add helper functions to extract the resource data type tags for both large and small resource data types.

PCI: Move pci_set_flags() from asm-generic/pci-bridge.h to linux/pci.h
The PCI flag management constants and functions were previously declared in include/asm-generic/pci-bridge.h. But they are not specific to bridges, and arches did not include pci-bridge.h consistently. Move the following interfaces and related constants to include/linux/pci.h and remove pci-bridge.h: pci_set_flags() pci_add_flags() pci_clear_flags() pci_has_flag() This fixes these warnings when building for some arches: drivers/pci/host/pcie-designware.c:562:20: error: 'PCI_PROBE_ONLY' undeclared (first use in this function) drivers/pci/host/pcie-designware.c:562:7: error: implicit declaration of function 'pci_has_flag' [-Werror=implicit-function-declaration] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

acpi: pci: Setup MSI domain for ACPI based pci devices
This patch introduces pci_msi_register_fwnode_provider() for irqchip to register a callback, to provide a way to determine appropriate MSI domain for a pci device. It also introduces pci_host_bridge_acpi_msi_domain(), which returns the MSI domain of the specified PCI host bridge with DOMAIN_BUS_PCI_MSI bus token. Then, it is assigned to pci device.

PCI: Turn off Request Attributes to avoid Chelsio T5 Completion erratum
The Chelsio T5 has a PCIe compliance erratum that causes Malformed TLP or Unexpected Completion errors in some systems, which may cause device access timeouts. Per PCIe r3.0, sec 2.2.9, "Completion headers must supply the same values for the Attribute as were supplied in the header of the corresponding Request, except as explicitly allowed when IDO is used." Instead of copying the Attributes from the Request to the Completion, the T5 always generates Completions with zero Attributes. The receiver of a Completion whose Attributes don't match the Request may accept it (which itself seems non-compliant based on sec 2.3.2), or it may handle it as a Malformed TLP or an Unexpected Completion, which will probably lead to a device access timeout. Work around this by disabling "Relaxed Ordering" and "No Snoop" in the Root Port so it always generate Requests with zero Attributes. This does affect all other devices which are downstream of that Root Port, but these are performance optimizations that should not make a functional difference. Note that Configuration Space accesses are never supposed to have TLP Attributes, so we're safe waiting till after any Configuration Space accesses to do the Root Port "fixup". Based on original work by Casey Leedom <leedom@chelsio.com> [bhelgaas: changelog, comments, rename to pci_find_pcie_root_port(), rework to use pci_upstream_bridge() and check for Root Port device type, edit diagnostics to clarify intent and devices affected] Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PCI: Set MPS to match upstream bridge
Firmware typically configures the PCIe fabric with a consistent Max Payload Size setting based on the devices present at boot. A hot-added device typically has the power-on default MPS setting (128 bytes), which may not match the fabric. The previous Linux default, in the absence of any "pci=pcie_bus_*" options, was PCIE_BUS_TUNE_OFF, in which we never touch MPS, even for hot-added devices. Add a new default setting, PCIE_BUS_DEFAULT, in which we make sure every device's MPS setting matches the upstream bridge. This makes it more likely that a hot-added device will work in a system with optimized MPS configuration. Note that if we hot-add a device that only supports 128-byte MPS, it still likely won't work because we don't reconfigure the rest of the fabric. Booting with "pci=pcie_bus_peer2peer" is a workaround for this because it sets MPS to 128 for everything.

This is not exported because I'd like to replace the variety of "scan root bus" interfaces with a single, more extensible interface that can handle the MSI controller, domain, pci_ops, resources, etc. I hope this interface is temporary.

PCI: Allocate ATS struct during enumeration
Previously, we allocated pci_ats structures when an IOMMU driver called
pci_enable_ats(). An SR-IOV VF shares the STU setting with its PF, so when
enabling ATS on the VF, we allocated a pci_ats struct for the PF if it
didn't already have one. We held the sriov->lock to serialize threads
concurrently enabling ATS on several VFS so only one would allocate the PF
pci_ats.
Gregor reported a deadlock here:
pci_enable_sriov
sriov_enable
virtfn_add
mutex_lock(dev->sriov->lock) # acquire sriov->lock
pci_device_add
device_add
BUS_NOTIFY_ADD_DEVICE notifier chain
iommu_bus_notifier
amd_iommu_add_device # iommu_ops.add_device
init_iommu_group
iommu_group_get_for_dev
iommu_group_add_device
__iommu_attach_device
amd_iommu_attach_device # iommu_ops.attach_device
attach_device
pci_enable_ats
mutex_lock(dev->sriov->lock) # deadlock
There's no reason to delay allocating the pci_ats struct, and if we
allocate it for each device at enumeration-time, there's no need for
locking in pci_enable_ats().
Allocate pci_ats struct during enumeration, when we initialize other
capabilities.
Note that this implementation requires ATS to be enabled on the PF first,
before on any of the VFs because the PF controls the STU for all the VFs.

PCI: Hold pci_slot_mutex while searching bus->slots list
Previously, pci_setup_device() and similar functions searched the pci_bus->slots list without any locking. It was possible for another thread to update the list while we searched it. Add pci_dev_assign_slot() to search the list while holding pci_slot_mutex.

PCI: Protect pci_bus->slots with pci_slot_mutex, not pci_bus_sem
Rajat Jain reported a deadlock when PCIe hot-add and AER recovery happen at
the same time:
thread 1:
pciehp_enable_slot
pciehp_configure_device
pci_bus_add_devices
pci_bus_add_device
device_attach
device_lock(dev) # acquire device lock
...
pciehp_probe
init_slot
pci_hp_register
pci_create_slot
down_write(pci_bus_sem) # deadlock here
thread 2:
aer_isr_one_error
aer_process_err_device
do_recovery
broadcast_error_message(..., report_error_detected)
pci_walk_bus(..., cb=report_error_detected, ...)
down_read(&pci_bus_sem) # acquire pci_bus_sem
report_error_detected(dev) # cb()
device_lock(dev) # deadlock here
Previously, the bus->devices and bus->slots list were protected by
pci_bus_sem. In pci_create_slot(), we held it for writing so we could
add to the bus->slots list.
Add a new local pci_slot_mutex to protect bus->slots. Hold pci_bus_sem for
reading while searching the bus->devices list.
