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

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: - Add Nvidia Vera Rubin to list of platforms that support P2PDMA (Leon Romanovsky) Endpoint framework: -

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 and resume (Sherry Sun) -

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) -

Flush MSI writes from endpoint before unmapping the iATU, as we already do for MSI-X writes (Niklas Cassel) - Unmap MSI iATU window before mapping MSI-X window, to avoid a subsequent MSI write using a disabled aperture and losing the interrupt (Niklas Cassel) -

Wed, 05 Aug 2026 12:50:14 +0200

PCI: cadence: Fix host/endpoint dependencies for cadence-plat driverThe cadence-plat driver has a single platform driver that can be built-inor a loadable module, but it calls two separate backend drivers dependingon whether it is a host or endpoint.If one of the mode is build as built-in and another as loadable module,we end up with a situation where the built-in pcie-cadence-plat drivertries to call the modular host or endpoint driver, which causes a linkfailure: ld: error: undefined symbol: cdns_pcie_ep_setup >>> referenced by pcie-cadence-plat.c >>> drivers/pci/controller/cadence/pcie-cadence-plat.o:(cdns_plat_pcie_probe) in archive vmlinux.a ld: error: undefined symbol: cdns_pcie_host_setup >>> referenced by pcie-cadence-plat.c >>> drivers/pci/controller/cadence/pcie-cadence-plat.o:(cdns_plat_pcie_probe) in archive vmlinux.aFix this by moving the 'select' of PCIE_CADENCE_HOST and PCIE_CADENCE_EPfrom the individual PLAT_HOST/PLAT_EP symbols into the common PCIE_CADENCE_PLATsymbol, conditioned on which backends (modes) are enabled.Fixes: 611627a4e5e4 ("PCI: cadence: Add module support for platform controller driver")Reported-by: Randy Dunlap Closes: https://lore.kernel.org/linux-next/589ea512-93c6-4e1c-83d7-ba45a0b35843@infradead.org/Signed-off-by: Aksh Garg Signed-off-by: Manivannan Sadhasivam Signed-off-by: Bjorn Helgaas Tested-by: Randy Dunlap Acked-by: Randy Dunlap Link: https://patch.msgid.link/20260805105014.3952686-1-a-garg7@ti.com List of files: /linux/drivers/pci/controller/cadence/Kconfig
