Merge branch 'pci/misc' (2025-03-27 13:15:05 -0500)

----------------------------------------------------------------

Enumeration:

- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)

- Log debug messages about reset methods being used (Bjorn Helgaas)

- Avoid reset when it has been disabled via sysfs (Nishanth Aravamudan)

- Add common pci-ep-bus.yaml schema for exporting several peripherals of
a single PCI function via devicetree (Andrea della Porta)

- Create DT nodes for PCI host bridges to enable loading device tree
overlays to create platform devices for PCI devices that have several
features that require multiple drivers (Herve Codina)

Resource management:

- Enlarge devres table[] to accommodate bridge windows, ROM, IOV BARs,
etc., and validate BAR index in devres interfaces (Philipp Stanner)

- Fix typo that repeatedly distributed resources to a bridge instead of
iterating over subordinate bridges, which resulted in too little space
to assign some BARs (Kai-Heng Feng)

- Relax bridge window tail sizing for optional resources, e.g., IOV BARs,
to avoid failures when removing and re-adding devices (Ilpo Järvinen)

- Allow drivers to enable devices even if we haven't assigned optional
IOV resources to them (Ilpo Järvinen)

- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)

- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)

- Fix s390 mmio_read/write syscalls, which didn't cause page faults in
some cases, which broke vfio-pci lazy mapping on first access (Niklas
Schnelle)

- Add pdev->non_mappable_bars to replace CONFIG_VFIO_PCI_MMAP, which was
disabled only for s390 (Niklas Schnelle)

- Support mmap of PCI resources on s390 except for ISM devices (Niklas
Schnelle)

ASPM:

- Delay pcie_link_state deallocation to avoid dangling pointers that
cause invalid references during hot-unplug (Daniel Stodden)

Power management:

- Allow PCI bridges to go to D3Hot when suspending on all non-x86 systems
(Manivannan Sadhasivam)

Power control:

- Create pwrctrl devices in pci_scan_device() to make it more symmetric
with pci_pwrctrl_unregister() and make pwrctrl devices for PCI bridges
possible (Manivannan Sadhasivam)

- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc. can
still access devices after pci_stop_dev() (Manivannan Sadhasivam)

- If there's a pwrctrl device for a PCI device, skip scanning it because
the pwrctrl core will rescan the bus after the device is powered on
(Manivannan Sadhasivam)

- Add a pwrctrl driver for PCI slots based on voltage regulators
described via devicetree (Manivannan Sadhasivam)

Bandwidth control:

- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the
set_pcie_cooling_state.sh test case (Yi Lai)

- Avoid a NULL pointer dereference when we run out of bus numbers to
assign for a bridge secondary bus (Lukas Wunner)

Hotplug:

- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and
NULL pointer checks (Lukas Wunner)

- Drop shpchp module init/exit logging, replace shpchp dbg() with
ctrl_dbg(), and remove unused dbg(), err(), info(), warn() wrappers
(Ilpo Järvinen)

- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)

- Drop unused cpcihp .get_power(), .set_power() function pointers
(Guilherme Giacomo Simoes)

- Disable hotplug interrupts in portdrv only when pciehp is not enabled
to avoid issuing two hotplug commands too close together (Feng Tang)

- Skip pciehp 'device replaced' check if the device has been removed to
address a deadlock when resuming after a device was removed during
system sleep (Lukas Wunner)

- Don't enable pciehp hotplug interupt when resuming in poll mode (Ilpo
Järvinen)

Virtualization:

- Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar
Dave)

DOE:

- Expose supported DOE features via sysfs (Alistair Francis)

- Allow DOE support to be enabled even if CXL isn't enabled (Alistair
Francis)

Endpoint framework:

- Convert PCI device data so pci-epf-test works correctly on big-endian
endpoint systems (Niklas Cassel)

- Add BAR_RESIZABLE type to endpoint framework and add DWC core support
for EPF drivers to set BAR_RESIZABLE type and size (Niklas Cassel)

- Fix pci-epf-test double free that causes an oops if the host reboots
and PERST# deassertion restarts endpoint BAR allocation (Christian
Bruel)

- Fix endpoint BAR testing so tests can skip disabled BARs instead of
reporting them as failures (Niklas Cassel)

- Widen endpoint test BAR size variable to accommodate BARs larger than
INT_MAX (Niklas Cassel)

- Remove unused tools 'pci' build target left over after moving tests to
tools/testing/selftests/pci_endpoint (Jianfeng Liu)

(Stanimir Varbanov)

- Expand inbound window map to 64GB so it can accommodate BCM2712
(Stanimir Varbanov)

- Add BCM2712 support and DT updates (Stanimir Varbanov)

- Apply link speed restriction before bringing link up, not after (Jim
Quinlan)

- Update Max Link Speed in Link Capabilities via the internal writable
register, not the read-only config register (Jim Quinlan)

- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)

- Disable regulators only when removing the bus immediately below a Root
Port because we don't support regulators deeper in the hierarchy (Jim
Quinlan)

Intel VMD host bridge driver:

- Convert vmd_dev.cfg_lock from spinlock_t to raw_spinlock_t so
pci_ops.read() will never sleep, even on PREEMPT_RT where spinlock_t
becomes a sleepable lock, to avoid calling a sleeping function from
invalid context (Ryo Takakura)

MediaTek PCIe Gen3 controller driver:

- Remove leftover mac_reset assert for Airoha EN7581 SoC (Lorenzo
Bianconi)

'reg[config]' for host controllers and 'reg[addr_space]' for endpoint
controllers (Frank Li)

.cpu_addr_fixup() when programming ATU (Frank Li)
