Current error message just prints the contents of PARF_INT_ALL_STATUS
register as if like the IRQ event number. It could mislead the users.
Reword it to make it clear that the error message is actually showing the
interrupt status register to help debug spurious IRQ events.
While at it, let's also switch over to dev_WARN_ONCE() so that any IRQ
storm won't flood the kernel log buffer.

Once the events are disabled in PARF_INT_ALL_MASK register, only the
enabled events will generate global IRQ. So there is no need to do the
masking again in the IRQ handler, drop it.
If there are any spurious IRQs getting generated, they will be reported
using the existing dev_err() in the handler.

The ACSPCIE module is capable of driving the reference clock required by
the PCIe Endpoint device. It is an alternative to on-board and external
reference clock generators. Enabling the output from the ACSPCIE module's
PAD IO Buffers requires clearing the "PAD IO disable" bits of the
ACSPCIE_PROXY_CTRL register in the CTRL_MMR register space.
Add support to enable the ACSPCIE reference clock output using the optional
device-tree property "ti,syscon-acspcie-proxy-ctrl".

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.

MSGF_LEG_MASK is laid out with INTA in bit 0, INTB in bit 1, INTC in bit 2,
and INTD in bit 3. Hardware IRQ numbers start at 0, and we register
PCI_NUM_INTX IRQs. So to enable INTA (aka hwirq 0) we should set bit 0.
Remove the subtraction of one.
This bug would cause INTx interrupts not to be delivered, as enabling INTB
would actually enable INTA, and enabling INTA wouldn't enable anything at
all. It is likely that this got overlooked for so long since most PCIe
hardware uses MSIs. This fixes the following UBSAN error:

With commit 5b6272e0efd5 ("PCI: qcom: Add OPP support to scale
performance"), OPP was used to control the interconnect and power domains
if the platform supported OPP. Also to maintain the backward compatibility
with platforms not supporting OPP but just ICC, the above mentioned commit
assumed that if ICC was not available on the platform, it would resort to
OPP.
Unfortunately, some old platforms don't support either ICC or OPP. On those
platforms, resorting to OPP in the absence of ICC throws below errors from
OPP core during suspend and resume:
qcom-pcie 1c08000.pcie: dev_pm_opp_set_opp: device opp doesn't exist
qcom-pcie 1c08000.pcie: _find_key: OPP table not found (-19)
Also, it doesn't make sense to invoke the OPP APIs when OPP is not
supported by the platform at all.
Add a "use_pm_opp" flag to identify whether OPP is supported and use it to
control invoking the OPP APIs.

__pci_reset_bus() calls pci_bridge_secondary_bus_reset() to perform the
reset and also waits for the Secondary Bus to become again accessible.
__pci_reset_bus() then calls pci_bus_restore_locked() that restores the PCI
devices connected to the bus, and if necessary, recursively restores also
the subordinate buses and their devices.
The logic in pci_bus_restore_locked() does not take into account that after
restoring a device on one level, there might be another Link Downstream
that can only start to come up after restore has been performed for its
Downstream Port device. That is, the Link may require additional wait until
it becomes accessible.
Similarly, pci_slot_restore_locked() lacks wait.
Amend pci_bus_restore_locked() and pci_slot_restore_locked() to wait for
the Secondary Bus before recursively performing the restore of that bus.

Bjorn suggests using pdev->dev.groups for attribute_groups constructed on
PCI device enumeration:
"Is it feasible to build an attribute group in pci_doe_init() and
add it to dev->groups so device_add() will automatically add them?"
https://lore.kernel.org/r/20231019165829.GA1381099@bhelgaas
Unfortunately on s390, pcibios_device_add() usurps pdev->dev.groups for
arch-specific attribute_groups, preventing its use for anything else.
Introduce an ARCH_PCI_DEV_GROUPS macro which arches can define in
<asm/pci.h>. The macro is visible in drivers/pci/pci-sysfs.c through the
inclusion of <linux/pci.h>, which in turn includes <asm/pci.h>.
On s390, define the macro to the three attribute_groups previously assigned
to pdev->dev.groups. Thereby pdev->dev.groups is made available for use by
the PCI core.
As a side effect, arch/s390/pci/pci_sysfs.c no longer needs to be compiled
into the kernel if CONFIG_SYSFS=n.

The sysfs "attention" file normally controls the Slot Control Attention

576243b3f9ea ("PCI: pciehp: Allow exclusive userspace control of
indicators") added pciehp_set_raw_indicator_status() to allow userspace to
directly control all four bits in both the Attention Indicator and the
Power Indicator fields via the "attention" file.
This is used on Intel VMD bridges so utilities like "ledmon" can use sysfs
"attention" to control up to 16 indicators for NVMe device RAID status.
abaaac4845a0 ("PCI: hotplug: Use FIELD_GET/PREP()") broke this by masking
the sysfs data with PCI_EXP_SLTCTL_AIC, which discards the upper two bits
intended for the Power Indicator Control field (PCI_EXP_SLTCTL_PIC).
For NVMe devices behind an Intel VMD, ledmon settings that use the
PCI_EXP_SLTCTL_PIC bits, i.e., ATTENTION_REBUILD (0x5), ATTENTION_LOCATE
(0x7), ATTENTION_FAILURE (0xD), ATTENTION_OFF (0xF), no longer worked
correctly.

pci_intx() becomes managed if pcim_enable_device() has been called in
advance. Commit 25216afc9db5 ("PCI: Add managed pcim_intx()") changed this
behavior so that pci_intx() always leads to creation of a separate device
resource for itself, whereas earlier, a shared resource was used for all
PCI devres operations.
Unfortunately, pci_intx() seems to be used in some drivers' remove() paths;
in the managed case this causes a device resource to be created on driver
detach, which causes .probe() to fail if the driver is reloaded:
pci 0000:00:1f.2: Resources present before probing
Fix the regression by only redirecting pci_intx() to its managed twin
pcim_intx() if the pci_command changes.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"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:

BAR resources (Philipp Stanner)
- Deprecate pcim_iomap_table() because uses like
"pcim_iomap_table()[0]" have no good way to return errors (Philipp
Stanner)

state (Philipp Stanner)
- Add pcim_intx() for use instead of pci_intx(), which is sometimes

- 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

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

- Rename .cpu_addr_fixup() parameter to reflect that it is a PCI
address, not a CPU address (Niklas Cassel)
TI Keystone PCIe controller driver:
- Validate IORESOURCE_BUS presence to avoid NULL pointer dereference
(Aleksandr Mishin)
- Work around AM65x/DRA80xM Errata #i2037 that corrupts TLPs and
causes processor hangs by limiting Max_Read_Request_Size (MRRS) and
Max_Payload_Size (MPS) (Kishon Vijay Abraham I)
- Leave BAR 0 disabled for AM654x to fix a regression caused by
6ab15b5e7057 ("PCI: dwc: keystone: Convert .scan_bus() callback to
use add_bus"), which caused a 45-second boot delay (Siddharth
Vadapalli)
Xilinx Versal CPM PCIe controller driver:
- Fix overlapping bridge registers and 32-bit BAR addresses in DT
binding (Thippeswamy Havalige)
MicroSemi Switchtec management driver:
- Make struct switchtec_class constant (Greg Kroah-Hartman)
Miscellaneous:
- Remove unused struct acpi_handle_node (Dr. David Alan Gilbert)
- Add missing MODULE_DESCRIPTION() macros (Jeff Johnson)"
