Merge tag 'pci-v6.17-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Enumeration:

- Allow built-in drivers, not just modular drivers, to use async
initial probing (Lukas Wunner)

- Support Immediate Readiness even on devices with no PM Capability
(Sean Christopherson)

- Consolidate definition of PCIE_RESET_CONFIG_WAIT_MS (100ms), the
required delay between a reset and sending config requests to a
device (Niklas Cassel)

- Add pci_is_display() to check for "Display" base class and use it
in ALSA hda, vfio, vga_switcheroo, vt-d (Mario Limonciello)

- Allow 'isolated PCI functions' (multi-function devices without a
function 0) for LoongArch, similar to s390 and jailhouse (Huacai
Chen)

Power control:

- Add ability to enable optional slot clock for cases where the PCIe
host controller and the slot are supplied by different clocks
(Marek Vasut)

PCIe native device hotplug:

- Fix runtime PM ref imbalance on Hot-Plug Capable ports caused by
misinterpreting a config read failure after a device has been
removed (Lukas Wunner)

- Avoid creating a useless PCIe port service device for pciehp if the
slot is handled by the ACPI hotplug driver (Lukas Wunner)

- Ignore ACPI hotplug slots when calculating depth of pciehp hotplug
ports (Lukas Wunner)

Virtualization:

- Save VF resizable BAR state and restore it after reset (Michał
Winiarski)

- Allow IOV resources (VF BARs) to be resized (Michał Winiarski)

- Add pci_iov_vf_bar_set_size() so drivers can control VF BAR size
(Michał Winiarski)

Endpoint framework:

- Add RC-to-EP doorbell support using platform MSI controller,
including a test case (Frank Li)

- Allow BAR assignment via configfs so platforms have flexibility in
determining BAR usage (Jerome Brunet)

Native PCIe controller drivers:

- Convert amazon,al-alpine-v[23]-pcie, apm,xgene-pcie,
axis,artpec6-pcie, marvell,armada-3700-pcie, st,spear1340-pcie to
DT schema format (Rob Herring)

- Use dev_fwnode() instead of of_fwnode_handle() to remove OF
dependency in altera (fixes an unused variable), designware-host,
mediatek, mediatek-gen3, mobiveil, plda, xilinx, xilinx-dma,
xilinx-nwl (Jiri Slaby, Arnd Bergmann)

- Convert aardvark, altera, brcmstb, designware-host, iproc,
mediatek, mediatek-gen3, mobiveil, plda, rcar-host, vmd, xilinx,
xilinx-dma, xilinx-nwl from using pci_msi_create_irq_domain() to
using msi_create_parent_irq_domain() instead; this makes the
interrupt controller per-PCI device, allows dynamic allocation of
vectors after initialization, and allows support of IMS (Nam Cao)

APM X-Gene PCIe controller driver:

- Rewrite MSI handling to MSI CPU affinity, drop useless CPU hotplug
bits, use device-managed memory allocations, and clean things up
(Marc Zyngier)

- Probe xgene-msi as a standard platform driver rather than a
subsys_initcall (Marc Zyngier)

Broadcom STB PCIe controller driver:

- Add optional DT 'num-lanes' property and if present, use it to
override the Maximum Link Width advertised in Link Capabilities
(Jim Quinlan)

Cadence PCIe controller driver:

- Use PCIe Message routing types from the PCI core rather than
defining private ones (Hans Zhang)

Freescale i.MX6 PCIe controller driver:

(Richard Zhu)

- Configure LUT for MSI/IOMMU in Endpoint mode so Root Complex can
trigger doorbel on Endpoint (Frank Li)

- Remove apps_reset (LTSSM_EN) from
imx_pcie_{assert,deassert}_core_reset(), which fixes a hotplug
regression on i.MX8MM (Richard Zhu)

Zhu)

Intel VMD host bridge driver:

- Add Intel Panther Lake (PTL)-H/P/U Vendor ID (George D Sworo)

Qualcomm PCIe controller driver:

- Add DT binding and driver support for SA8255p, which supports ECAM
for Configuration Space access (Mayank Rana)

- Update DT binding and driver to describe PHYs and per-Root Port
resets in a Root Port stanza and deprecate describing them in the
host bridge; this makes it possible to support multiple Root Ports
in the future (Krishna Chaitanya Chundru)

- Add Qualcomm QCS615 to SM8150 DT binding (Ziyue Zhang)

- Add Qualcomm QCS8300 to SA8775p DT binding (Ziyue Zhang)

- Drop TBU and ref clocks from Qualcomm SM8150 and SC8180x DT
bindings (Konrad Dybcio)

- Document 'link_down' reset in Qualcomm SA8775P DT binding (Ziyue
Zhang)

(Niklas Cassel)

Rockchip PCIe controller driver:

- Drop unused PCIe Message routing and code definitions (Hans Zhang)

- Remove several unused header includes (Hans Zhang)

- Prevent race between link training and register update via DBI by
inhibiting link training after hot reset and link down (Wilfred
Mallawa)

- Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
(Niklas Cassel)

Sophgo PCIe controller driver:

- Add DT binding and driver for Sophgo SG2044 PCIe controller driver
in Root Complex mode (Inochi Amaoto)

Synopsys DesignWare PCIe controller driver:

- Add required PCIE_RESET_CONFIG_WAIT_MS after waiting for Link up on
Ports that support > 5.0 GT/s. Slower Ports still rely on the
not-quite-correct PCIE_LINK_WAIT_SLEEP_MS 90ms default delay while
waiting for the Link (Niklas Cassel)"

Merge tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)

- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)

Resource management:

- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)

- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)

- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)

- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)

Error handling:

- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)

- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)

- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)

- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)

Power management:

- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)

- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)

Power control:

- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)

- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)

Bandwidth control:

- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)

- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)

PCIe native device hotplug:

- Ignore Presence Detect Changed caused by DPC.

pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)

- Ignore Link Down/Up caused by Secondary Bus Reset.

On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)

Virtualization:

- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)

Endpoint framework:

- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)

- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)

- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)

- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

Common host controller library:

- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)

Apple PCIe controller driver:

- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)

- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)

- Skip ports disabled in DT when setting up ports (Janne Grunau)

- Add t6020 compatible string (Alyssa Rosenzweig)

- Add T602x PCIe support (Hector Martin)

- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)

- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)

- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)

- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)

Cadence PCIe controller driver:

- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)

- Make the cadence core buildable as a module (Kishon Vijay Abraham I)

- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)

Freescale i.MX6 PCIe controller driver:

- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)

- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)

- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)

- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)

- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

Mobiveil PCIe controller driver:

- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)

NVIDIA Tegra194 PCIe controller driver:

- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)

Qualcomm PCIe controller driver:

- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)

- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)

- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)

- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)

- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

Renesas R-Car PCIe controller driver:

- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)

Rockchip PCIe controller driver:

- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)

- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)

Rockchip DesignWare PCIe controller driver:

- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)

- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)

- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)

- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)

Synopsys DesignWare PCIe controller driver:

- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)

- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)

- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)

TI J721E PCIe driver:

- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)

- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)

Device tree bindings:

- Add qcom DT binding for 'global' interrupt (PCIe controller and
link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan

Miscellaneous:

- Drop 'pci' suffix from intel_mid_pci.c filename to match similar

PCI: mobiveil: Return bool from link up check

PCIe link status check is supposed to return a boolean to indicate whether
the link is up or not. So update ls_g4_pcie_link_up() to return bool and
also simplify the LTSSM state check.

Merge tag 'pci-v6.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

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)

pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)

"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)

prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)
