The following changes since commit 8f0b4cce4481fb22653697cced8d0d04027cb1e8:
Linux 6.19-rc1 (2025-12-14 16:05:07 +1200)

Merge branch 'pci/misc' (2026-02-06 17:09:53 -0600)
You should see this conflict:
upstream 0cc13256b605 ("PCI: qcom: Remove ASPM L0s support for MSM8996 SoC")
vs PCI 8d8db7dbf218 ("PCI: qcom: Rename PERST# assert/deassert helpers for uniformity")
6a1394990902 ("PCI: qcom: Remove DPC Extended Capability")
7c29cd0fdc07 ("PCI: qcom: Remove MSI-X Capability for Root Ports")
If you merge the IOMMU PR first, you might see this conflict:
iommu f5b16b802174 ("PCI: Suspend iommu function prior to resetting a device")
vs PCI 183c291caa34 ("PCI: Use lockdep_assert_held(pci_bus_sem) to verify lock is held")
(adjacent #includes added)
My resolution is here:
https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/log/?h=v7.0-merge
----------------------------------------------------------------
Enumeration:
- Don't try to enable Extended Tags on VFs since that bit is Reserved and
causes misleading log messages (Håkon Bugge)
- Initialize Endpoint Read Completion Boundary to match Root Port,
regardless of ACPI _HPX (Håkon Bugge)
- Apply _HPX PCIe Setting Record only to AER configuration, and only when
OS owns PCIe hotplug but not AER, to avoid clobbering Extended Tag and
Relaxed Ordering settings (Håkon Bugge)
Resource management:
- Move CardBus code to setup-cardbus.c and only build it when
CONFIG_CARDBUS is set (Ilpo Järvinen)
- Fix bridge window alignment with optional resources, where additional
alignment requirement was previously lost (Ilpo Järvinen)
- Stop over-estimating bridge window size since they are now assigned
without any gaps between them (Ilpo Järvinen)
- Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening for
nested bridges and endpoints (Ilpo Järvinen)
- Add pbus_mem_size_optional() to handle sizes of optional resources
(SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)
- Don't claim disabled bridge windows to avoid spurious claim failures
(Ilpo Järvinen)
Driver binding:
- Fix device reference leak in pcie_port_remove_service() (Uwe
Kleine-König)
- Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
portdrv.c (Uwe Kleine-König)
- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)
Error handling:
- Clear stale errors on reporting agents upon probe so they don't look
like recent errors (Lukas Wunner)
- Add generic RAS tracepoint for hotplug events (Shuai Xue)
- Add RAS tracepoint for link speed changes (Shuai Xue)
Power management:
- Avoid redundant delay on transition from D3hot to D3cold if the device
was already in D3hot (Brian Norris)
- Prevent runtime suspend until devices are fully initialized to avoid
saving incompletely configured device state (Brian Norris)
Power control:
- Add power_on/off callbacks with generic signature to pwrseq, tc9563,
and slot drivers so they can be used by pwrctrl core (Manivannan
Sadhasivam)
- Add PCIe M.2 connector support to the slot pwrctrl driver (Manivannan
Sadhasivam)
- Switch to pwrctrl interfaces to create, destroy, and power on/off
devices, calling them from host controller drivers instead of the PCI
core (Manivannan Sadhasivam)
- Drop qcom .assert_perst() callbacks since this is now done by the
controller driver instead of the pwrctrl driver (Manivannan Sadhasivam)
Virtualization:
- Remove an incorrect unlock in pci_slot_trylock() error handling (Jinhui
Guo)
- Lock the bridge device for slot reset (Keith Busch)
- Enable ACS after IOMMU configuration on OF platforms so ACS is enabled
an all devices; previously the first device enumerated (typically a
Root Port) didn't have ACS enabled (Manivannan Sadhasivam)
- Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
work around hardware erratum; previously ACS SV was only temporarily
disabled, which worked for enumeration but not after reset (Manivannan
Sadhasivam)
Peer-to-peer DMA:
- Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
when removing the PCI device (Hou Tao)
- Remove incorrect p2pmem_alloc_mmap() warning about page refcount (Hou
Tao)
Endpoint framework:
- Add configfs sub-groups synchronously to avoid NULL pointer dereference
when racing with removal (Liu Song)
- Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
functions (Manikanta Maddireddy)
ASPEED PCIe controller driver:
- Add ASPEED Root Complex DT binding and driver (Jacky Chou)
Freescale i.MX6 PCIe controller driver:
- Add DT binding and driver support for an optional external refclock in
addition to the refclock from the internal PLL (Richard Zhu)
- Fix CLKREQ# control so host asserts it during enumeration and Endpoints
can use it afterwards to exit the L1.2 link state (Richard Zhu)
NVIDIA Tegra PCIe controller driver:
- Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear down
MSI domains to be built as modules (Aaron Kling)
- Allow pci-tegra to be built as a module (Aaron Kling)
NVIDIA Tegra194 PCIe controller driver:
- Relax Kconfig so tegra194 can be built for platforms beyond Tegra194
(Vidya Sagar)
Qualcomm PCIe controller driver:
- Merge SC8180x DT binding into SM8150 (Krzysztof Kozlowski)
- Move SDX55, SDM845, QCS404, IPQ5018, IPQ6018, IPQ8074 Gen3, IPQ8074,
IPQ4019, IPQ9574, APQ8064, MSM8996, APQ8084 to dedicated schema
(Krzysztof Kozlowski)
- Add DT binding and driver support for SA8255p Endpoint being configured
by firmware (Mrinmay Sarkar)
- Parse PERST# from all PCIe bridge nodes for future platforms that will
have PERST# in Switch Downstream Ports as well as in Root Ports
(Manivannan Sadhasivam)
Renesas RZ/G3S PCIe controller driver:
- Use pci_generic_config_write() since the writability provided by the
custom wrapper is unnecessary (Claudiu Beznea)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi Amaoto)
Synopsys DesignWare PCIe controller driver:
- Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
pointer to the preceding Capability, to allow removal of Capabilities
that are advertised but not fully implemented (Qiang Yu)
- Remove MSI and MSI-X Capabilities in platforms that can't support them,
so the PCI core automatically falls back to INTx (Qiang Yu)
- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status for
drivers that support this (Shawn Lin)
- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if link
is not up to avoid an unnecessary timeout (Manivannan Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up IRQs
to trigger enumeration instead of waiting for link to be up because the
PCI core doesn't allocate bus number space for hierarchies that might
be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming it
dynamically, which is slow and racy with respect to other concurrent
traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with the
link (Manivannan Sadhasivam)
- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers are
not accessible after PME_Turn_Off, simply wait 10ms instead of polling
for L2/L3 Ready (Richard Zhu)
- Use multiple iATU entries to map large bridge windows and DMA ranges
when necessary instead of failing (Samuel Holland)
- Add EPC dynamic_inbound_mapping feature bit for Endpoint Controllers
that can update BAR inbound address translation without requiring EPF
driver to clear/reset the BAR first, and advertise it for DWC-based
Endpoints (Koichiro Den)
- Add EPC subrange_mapping feature bit for Endpoint Controllers that can
map multiple independent inbound regions in a single BAR, implement
subrange mapping, advertise it for DWC-based Endpoints, and add
Endpoint selftests for it (Koichiro Den)
- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)
- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings, and
Address Match Mode (Aksh Garg)
- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)
Miscellaneous:
- Use system_percpu_wq and WQ_PERCPU to explicitly request per-CPU work
so WQ_UNBOUND can eventually be removed (Marco Crivellari)
