Merge tag 'pci-v7.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Resource management:

- Add hotplug reservation only once (not at each level of the
hierarchy) so bridge windows don't grow more than necessary (Ilpo
Järvinen)

Driver binding:

- Rework device matching so device ID lifetime only needs to cover
the probe path since dynamic IDs can be removed at any time (Gary
Guo)

Error handling:

- Update mappings of AER errors to agent & layer and log them for
each individual error when multiple errors detected (Lukas Wunner)

- Log Error Source only once, not twice in separate messages (Lukas
Wunner)

- Emit TLP Log only for unmasked errors (Lukas Wunner)

- Support Advisory Non-Fatal Errors (Lukas Wunner)

- Allow DPC on all Downstream Ports, not just Root Ports, when OS
controls AER (Darshit Shah)

ASPM:

- Program the same ASPM Control values for every function of
multi-function devices, as recommended by the PCIe spec (Krishna
Chaitanya Chundru)

- Avoid L0s for Realtek RTS525A, where it causes an AER interrupt
storm (Max Lee)

- Avoid ASPM L0s, L1, and L1 PM Substates based on 'aspm-no-l0s',
'aspm-no-l1' [1], and 'aspm-no-l1ss' DT properties (Krishna
Chaitanya Chundru)

Power management:

- Allow D3 for native hotplug-capable Root Ports on non-x86 platforms
(we avoid D3 for these ports on x86 because some old platforms
didn't validate it) (Manivannan Sadhasivam)

- Allow portdrv to claim Ports even if they don't support services
(AER, PME, DPC, hotplug, etc) so it can do power management (Brian
Norris)

Power control:

- Add support for PCIe WAKE# interrupt when described via DT (Krishna
Chaitanya Chundru)

- For the TC9563 PCIe switch:

- Take a reference on the I2C adapter to avoid uninterruptible
hang when unloading an I2C module while in-use (Johan Hovold)

- Update DT binding and driver to restrict Tx Amplitude, DFE and
N_FTS to USP, DSP1 and DSP2 (Manivannan Sadhasivam)

- Power off only external-facing ports (DSP1, DSP2), leaving USP
and DSP3 (aka VDSP) powered up (Manivannan Sadhasivam)

- Move integrated MAC Endpoint out of the list of internal ports
and configure it separately (Manivannan Sadhasivam)

Virtualization:

- Add ACS quirk for Pericom PI7C9X2G608 switches (Tim Harvey)

- Fix a long-standing bug in the Intel PCH Root Port MPC ACS quirk
that didn't update the intended INTEL_MPC_REG_IRBNCE bit because it
used a 16-bit config write when a 32-bit write was intended
(Mohamad Raizudeen)

Procfs:

- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)

- Warn on user-space writes to kernel-exclusive config space regions,
as we already do for sysfs (Krzysztof Wilczyński)

- Check credentials of opener, not reader, for config space reads, as
we already do for sysfs (Krzysztof Wilczyński)

Sysfs:

- In pci_write_legacy_io(), avoid out-of-bounds reads from the user
buffer and fix incorrect ioport write data (1-byte writes on
little-endian powerpc, 2- and 4-byte writes on big-endian powerpc)
(Krzysztof Wilczyński)

- In pci_read_legacy_io(), fix incorrect ioport read data for 2- and
4-byte reads on big-endian powerpc (Krzysztof Wilczyński)

- Fix I/O port accessor argument order in Alpha pci_legacy_write()
(Krzysztof Wilczyński)

- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)

- Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because
the arch doesn't support it, as we do for procfs (Krzysztof
Wilczyński)

- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we
do for other config space accessors (Krzysztof Wilczyński)

Peer-to-peer DMA:

Native PCIe controllers:

- Use common wait time definitions for PCIe link monitoring instead
of defining driver-private duplicates (Thierry Reding)

Generic host bridge driver:

- Fix NULL pointer dereference that caused enumeration failures on
32-bit CAM systems (Steffen Persvold)

Amlogic Meson PCIe controller driver:

- Correct the PERST# GPIO state so it remains asserted until power
and REFCLK become stable to fix enumeration failure (Ronald
Claveau)

Freescale i.MX6 PCIe controller driver:

- Add imx6 intr/aer/pme interrupt lines for i.MX95 (Richard Zhu)

the host bridge (Sherry Sun)

- Fix build issues when PCI_PWRCTRL_GENERIC or PCI_HOST_COMMON is a
module (Arnd Bergmann)

- Create pwrctrl devices only once by doing it from imx_pcie_probe()
instead of imx_pcie_host_init(), which is used during both probe

during suspend to preserve wakeup capability (Sherry Sun)

- Add runtime PM support for i.MX95 to allow dynamic power management

Intel VMD host bridge driver:

- Support device ID 0x28C1 and assume that BIOS has already
enumerated the hierarchy below VMD and stored bus range info for OS
to use (Nirmal Patel)

- Add support for VMCONFIG BUS_RESTRICT_CFG=3, which makes it
possible to enumerate downstream devices on Intel Arrow Lake-HX
systems and probably others (Ali Alaei)

subsequent MSI write using a disabled aperture and losing the
interrupt (Niklas Cassel)

- Change endpoint .pre_init() and .init() callbacks to return errors
and handle them (Marek Vasut)

UltraRISC PCIe controller driver:

- Add 'core', 'dbi', and 'aux' clocks to DT binding and manage them

PCI: dw-rockchip: Implement .reset_root_port() and use for link down

The PCIe link may go down in cases like firmware crashes or unstable
connections. When this occurs, the Root Port must be reset to restore the
functionality. However, the current driver lacks link down handling,
forcing users to reboot the system to recover.

Implement the .reset_root_port() callback for link down handling for the
Rockchip DWC PCIe host controller. The RC is reset, reconfigured, and link
training initiated to recover from the link down event.

This also by extension fixes issues with sysfs-initiated bus resets.
Currently, the endpoint device is non-functional after a sysfs initiated
bus reset (it may link up with downgraded link status). With the link down
handling support, a sysfs initiated bus reset works as intended. Testing
conducted on a ROCK5B board with an M.2 NVMe drive.

PCI: rcar-gen4: Configure AXIINTC if iMSI-RX is not used

When MSI is enabled but the DWC built-in iMSI-RX is not used, MSI must
be handled via the GIC ITS. Configure all controller MSI registers
accordingly.

Set or clear the MSICAP0 MSIE bit and the PCIEINTSTS0EN MSI_CTRL_INT
bit based on the MSI enable state. Set both bits when MSI is enabled.
Clear both bits when MSI is disabled.

When MSI is disabled, or when MSI is enabled together with iMSI-RX,
clear AXIINTCADDR and AXIINTCCONT to disable any pass through of MSI
TLPs onto the AXI bus and further into the GIC ITS translation
registers.

When MSI is enabled and iMSI-RX is not used, program AXIINTCADDR with
the target address of the GIC ITS translation register, and program
AXIINTCCONT to enable MSI TLP pass through onto the AXI bus and into
the GIC ITS. This configuration allows the GIC ITS to handle MSI
instead of the integrated iMSI-RX.

The driver includes linux/irqchip/arm-gic-v3.h which pulls in headers
which are available only on ARM and ARM64, on other architectures the
headers are not present and the driver fails to build. This driver is
used only on ARM64 hardware, so isolate its build only to ARM64 to avoid
build failures on other architectures.

Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

Merge tag 'pci-v7.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
around a WiFi device defect; use a quirk or boot-time
"pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)

- Always lift 2.5GT/s restriction in PCIe failed link retraining to
avoid clamping a link to 2.5GT/s after hot-plug changes the device
(Maciej W. Rozycki)

- Request bus reassignment when not probe-only to fix an enumeration
regression on Marvell CN106XX and possibly other DT-based systems
(Ratheesh Kannoth)

- Fix procfs race between pci_proc_init() and pci_bus_add_device()
that resulted in 'proc_dir_entry ... already registered' warnings
and pointer corruption (Krzysztof Wilczyński)

- Fix sysfs race that causes 'duplicate filename' warnings and boot
panics by converting PCI resource files to static attributes
(Krzysztof Wilczyński)

- Expose sysfs 'resourceN_resize' attributes only on platforms with
PCI mmap (Krzysztof Wilczyński)

- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
attributes (Krzysztof Wilczyński)

- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
mmap path to match the generic path (Krzysztof Wilczyński)

- Use kstrtobool() to parse the 'rom' attribute input to avoid the
unexpected behavior of enabling the ROM when writing '0' with no
trailing newline (Krzysztof Wilczyński)

Resource management:

avoid page faults and alignment faults (Guixin Liu)

ASPM:

- Don't reconfigure ASPM when entering low-power D-state; only do it
when returning back to D0 (Carlos Bilbao)

Power management:

- During suspend, set power state to 'unknown' for all devices, not
just those with drivers (Lukas Wunner)

- Skip restoring Resizable BARs and VF Resizable BARs if device
doesn't respond to config reads, to avoid invalid array accesses
(Marco Nenciarini)

- Add pci_suspend_retains_context() so drivers can tell whether
devices retain internal state across suspend/resume, since some
platforms reset devices on suspend; use this in nvme to avoid
issues on Qcom RCs (Manivannan Sadhasivam)

Power control:

- Only to power on/off devices that actually support power control to
avoid poking at incompatible devices mentioned in DT (Manivannan
Sadhasivam)

Virtualization and resets:

- Log device readiness timeouts as errors, not warnings, because the
device is likely unusable in this case (Bjorn Helgaas)

- Wait for device readiness after soft reset (D3hot ->
D0uninitialized transition), when the device may respond with
Request Retry Status (RRS) if it needs more time to initialize
(Bjorn Helgaas)

- Drop unnecessary retries when restoring BARs because resets should
now already include all required delays (Lukas Wunner)

- Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
terminates uncleanly (Jose Ignacio Tornos Martinez)

which seem not to support it correctly (Jose Ignacio Tornos
Martinez)

through (Koichiro Den)

- Cache sleepable pci_irq_vector() value at ISR setup to avoid
calling it from hardirq context (Koichiro Den)

atomic context, e.g., when setting bits in NTB peer doorbells in
the ntb_peer_db_set() path (Koichiro Den)

- Report 0-based vNTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)

- Prevent configfs writes to vNTB db_count and other values that are
already in use after EPC attach (Koichiro Den)

- Account for vNTB db_valid reserved slots (link event 0 and
historically skipped slot 1) so they don't appear as valid
doorbells (Koichiro Den)

can use multiple vectors and avoid thundering herds (Koichiro Den)

- Report 0-based NTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)

- Fix doorbell bitmask and IRQ vector handling to clear only
specified bits, use the correct vector for non-contiguous Linux IRQ
numbers, and validate incoming vectors (Koichiro Den)

- Implement NTB .db_vector_count()/mask() for doorbells so clients
can use multiple vectors (Koichiro Den)

j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)

- Protect root bus removal with rescan lock in altera, brcmstb,
cadence, dwc, iproc, mediatek, plda, rockchip to prevent
use-after-free or crashes when racing with sysfs rescan or hotplug
(Hans Zhang)

- Add pci_host_common_parse_ports() for use by any native driver to
parse Root Port properties (per-Link features like width, speed,
PHY, power and reset control, etc should be described in Root Port
stanzas, not the host bridge; currently only reset GPIOs
implemented) (Sherry Sun)

Freescale i.MX6 PCIe controller driver:

- Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
functions (Richard Zhu)

- Add .shutdown() to assert PERST# before powering down device (Jian
Yang)

- Do full device power down on removal, including asserting PERST#,

since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
Chundru)

- Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
