PCI/pwrctl: Rescan bus on a separate thread
If we trigger the bus rescan from sysfs, we'll try to lock the PCI rescan
mutex recursively and deadlock - the platform device will be populated and
probed on the same thread that handles the sysfs write.
Add a workqueue to the pwrctl code on which we schedule the rescan for
controlled PCI devices. While at it: add a new interface for initializing
the pwrctl context where we'd now assign the parent device address and
initialize the workqueue.

PCI: Don't rely on of_platform_depopulate() for reused OF-nodes
of_platform_depopulate() doesn't play nicely with reused OF nodes - it
ignores the ones that are not marked explicitly as populated and it may
happen that the PCI device goes away before the platform device in which
case the PCI core clears the OF_POPULATED bit.
Unconditionally unregister the platform devices for child nodes when
stopping the PCI device.

iommu: Allow ATS to work on VFs when the PF uses IDENTITY
PCI ATS has a global Smallest Translation Unit field that is located in the PF but shared by all of the VFs. The expectation is that the STU will be set to the root port's global STU capability which is driven by the IO page table configuration of the iommu HW. Today it becomes set when the iommu driver first enables ATS. Thus, to enable ATS on the VF, the PF must have already had the correct STU programmed, even if ATS is off on the PF. Unfortunately the PF only programs the STU when the PF enables ATS. The iommu drivers tend to leave ATS disabled when IDENTITY translation is being used. Thus we can get into a state where the PF is setup to use IDENTITY with the DMA API while the VF would like to use VFIO with a PAGING domain and have ATS turned on. This fails because the PF never loaded a PAGING domain and so it never setup the STU, and the VF can't do it. The simplest solution is to have the iommu driver set the ATS STU when it probes the device. This way the ATS STU is loaded immediately at boot time to all PFs and there is no issue when a VF comes to use it. Add a new call pci_prepare_ats() which should be called by iommu drivers in their probe_device() op for every PCI device if the iommu driver supports ATS. This will setup the STU based on whatever page size capability the iommu HW has.

PCI: qcom-ep: Disable MHI RAM data parity error interrupt for SA8775P SoC
SA8775P SoC has support for the hardware parity check feature on the MHI
RAM (entity that holds MHI registers, etc.) But due to a hardware bug in
the parity check logic, the data parity error interrupt is getting
generated all the time when using MHI. So the hardware team has suggested
disabling the parity check error to work around the hardware bug.
Mask the parity error interrupt in PARF_INT_ALL_5_MASK register.
Fixes:

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)
- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)
Resource management:
- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)
- Export find_resource_space() for use by PCI core, which needs to
learn whether there is available space for a bridge window (Ilpo
Järvinen)
- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)
- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)
- Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)
- Extend use of DT "linux,pci-probe-only" property so it works
per-host bridge as well as globally (Vidya Sagar)
- Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)
Driver binding:
- Add devres infrastructure for managed request and map of partial
BAR resources (Philipp Stanner)
- Deprecate pcim_iomap_table() because uses like
"pcim_iomap_table()[0]" have no good way to return errors (Philipp
Stanner)
- Add an always-managed pcim_request_region() for use instead of
pci_request_region() and similar, which are sometimes managed
depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)
- Reimplement pcim_set_mwi() so it doesn't need to keep store MWI
state (Philipp Stanner)
- Add pcim_intx() for use instead of pci_intx(), which is sometimes
managed depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)
- Add managed pcim_iomap_range() to allow mapping of a partial BAR
(Philipp Stanner)
- Fix a devres mapping leak in drm/vboxvideo (Philipp Stanner)
Error handling:
- Add missing bridge locking in device reset path and add a warning
for other possible lock issues (Dan Williams)
- Fix use-after-free on concurrent DPC and hot-removal (Lukas Wunner)
Power management:
- Disable AER and DPC during suspend to avoid spurious wakeups if
they share an interrupt with PME (Kai-Heng Feng)
PCIe native device hotplug:
- Detect if a device was removed or replaced during system sleep so
we don't assume a new device is the one that used to be there
(Lukas Wunner)
Virtualization:
- Add an ACS quirk for Broadcom BCM5760X multi-function NIC; it
prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)
Peer-to-peer DMA:
- Add a "pci=config_acs=" kernel command-line parameter to relax
default ACS settings to enable additional peer-to-peer
configurations. Requires expert knowledge of topology and ACS
operation (Vidya Sagar)
Endpoint framework:
- Remove unused struct pci_epf_group.type_group (Christophe JAILLET)
- Fix error handling in vpci_scan_bus() and epf_ntb_epc_cleanup()
(Dan Carpenter)
- Make struct pci_epc_class constant (Greg Kroah-Hartman)
- Remove unused pci_endpoint_test_bar_{readl,writel} functions
(Jiapeng Chong)
- Rename "BME" to "Bus Master Enable" (Manivannan Sadhasivam)
- Rename struct pci_epc_event_ops.core_init() callback to epc_init()
(Manivannan Sadhasivam)
- Move DMA init to MHI .epc_init() callback for uniformity
(Manivannan Sadhasivam)
- Cancel EPF test delayed work when link goes down (Manivannan
Sadhasivam)
- Add struct pci_epc_event_ops.epc_deinit() callback for cleanup
needed on fundamental reset (Manivannan Sadhasivam)
- Add 64KB alignment to endpoint test to support Rockchip rk3588
(Niklas Cassel)
- Optimize endpoint test by using memcpy() instead of readl() (Niklas
Cassel)
Device tree bindings:
- Add generic "ats-supported" property to advertise that a PCIe Root
Complex supports ATS (Jean-Philippe Brucker)
Amazon Annapurna Labs PCIe controller driver:
- Validate IORESOURCE_BUS presence to avoid NULL pointer dereference
(Aleksandr Mishin)
Axis ARTPEC-6 PCIe controller driver:
- Rename .cpu_addr_fixup() parameter to reflect that it is a PCI
address, not a CPU address (Niklas Cassel)
Freescale i.MX6 PCIe controller driver:
- Convert to agnostic GPIO API (Andy Shevchenko)
Freescale Layerscape PCIe controller driver:
- Make struct mobiveil_rp_ops constant (Christophe JAILLET)
- Use new generic dw_pcie_ep_linkdown() to handle link-down events
(Manivannan Sadhasivam)

- Rename find_resource() to find_resource_space() to make it more descriptive for exporting outside resource.c (Ilpo Järvinen) - Document find_resource_space() and the resource_constraint struct it uses (Ilpo Järvinen) - Add typedef resource_alignf to make it simpler to declare allocation constraint alignf callbacks (Ilpo Järvinen) - Open-code the no-constraint simple alignment case to make the simple_align_resource() default callback unnecessary (Ilpo Järvinen) - Export find_resource_space() because PCI bridge window allocation needs to learn whether there's space for a window (Ilpo Järvinen) - Fix a double-counting problem in PCI calculate_memsize() that led to allocating larger windows each time a bus was removed and rescanned (Ilpo Järvinen) - When we don't have space to allocate larger bridge windows, allocate windows only large enough for the downstream devices to prevent cases where a device worked originally, but not after being removed and re-added (Ilpo Järvinen) * pci/resource: PCI: Relax bridge window tail sizing rules PCI: Make minimum bridge window alignment reference more obvious PCI: Fix resource double counting on remove & rescan resource: Export find_resource_space() resource: Handle simple alignment inside __find_resource_space() resource: Use typedef for alignf callback resource: Document find_resource_space() and resource_constraint resource: Rename find_resource() to find_resource_space() |

Merge branch 'pci/hotplug'
- Detect if a device was removed or replaced during system sleep so we don't assume a new device is the one that used to be there. This uses Vendor/Device/Subsystem/Class/Revision and Device Serial Number (if implemented), so it's not fool-proof and drivers may know how to detect more cases (Lukas Wunner) - Add missing MODULE_DESCRIPTION() macro (Jeff Johnson) * pci/hotplug: PCI: acpiphp: Add missing MODULE_DESCRIPTION() macro PCI: pciehp: Detect device replacement during system sleep |

Merge branch 'pci/devres'
- Add pcim_add_mapping_to_legacy_table() and pcim_remove_mapping_from_legacy_table() helper functions to simplify devres iomap table (Philipp Stanner) - Reimplement devres that take a bit mask of BARs in a way that can be used to map partial BARs as well as entire BARs (Philipp Stanner) - Deprecate pcim_iomap_table() and pcim_iomap_regions_request_all() in favor of pcim_* request plus pcim_* mapping (Philipp Stanner) - Add pcim_request_region(), a managed interface to request a single BAR (Philipp Stanner) - Use the existing pci_is_enabled() interface to replace the struct devres.enabled bit (Philipp Stanner) - Move the struct pci_devres.pinned bit to struct pci_dev (Philipp Stanner) - Reimplement pcim_set_mwi() so it uses its own devres cleanup callback instead of a special-purpose bit in struct pci_devres (Philipp Stanner) - Add pcim_intx(), which is unambiguously managed, unlike pci_intx(), which is managed if pcim_enable_device() has been called but unmanaged otherwise (Philipp Stanner) - Remove pcim_release(), which is no longer needed after previous cleanups of pcim_set_mwi() and pci_intx() (Philipp Stanner) - Add pcim_iomap_range(), a managed interface to map part of a BAR (Philipp Stanner) - Fix vboxvideo leak by using the new pcim_iomap_range() instead of the unmanaged pci_iomap_range() (Philipp Stanner) * pci/devres: drm/vboxvideo: fix mapping leaks PCI: Add managed pcim_iomap_range() PCI: Remove legacy pcim_release() PCI: Add managed pcim_intx() PCI: Give pcim_set_mwi() its own devres cleanup callback PCI: Move struct pci_devres.pinned bit to struct pci_dev PCI: Remove struct pci_devres.enabled status bit PCI: Document hybrid devres hazards PCI: Add managed pcim_request_region() PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all() PCI: Add managed partial-BAR request and map infrastructure PCI: Add devres helpers for iomap table PCI: Add and use devres helper for bit masks |

PCI: loongson: Enable MSI in LS7A Root Complex
The LS7A chipset can be used as part of a PCIe Root Complex with Loongson-3C6000 and similar CPUs. In this case, DEV_LS7A_PCIE_PORT5 has a PCI_CLASS_BRIDGE_HOST class code, and it is a Type 0 Function whose config space provides access to Root Complex registers. The DEV_LS7A_PCIE_PORT5 has an MSI Capability, and its MSI Enable bit must be set before other devices below the Root Complex can use MSI. This is not the standard PCI behavior of MSI Enable, so the normal PCI MSI code does not set it. Set the DEV_LS7A_PCIE_PORT5 MSI Enable bit via a quirk so other devices below the Root Complex can use MSI.
