Merge branch 'pci/misc' (2026-10-21 13:20:39 -0500)
You should see this trivial drivers/pci/pcie/aer.c conflict:
upstream 79c168e2aa95 ("PCI/AER: Skip error recovery on false alarms")
vs PCI d4c842c3af5b ("PCI/AER: Fix memory leak in aer_recover_work_func() when pci_dev is missing")
Preferred resolution at https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/tree/drivers/pci/pcie/aer.c?h=v7.4-merge#n1395
----------------------------------------------------------------
Enumeration:
- Set supported_speeds in set_pcie_port_type() so sparc64 and powerpc,
which call it via of_create_pci_dev() instead of the usual
pci_setup_device(), correctly set the supported PCIe link speeds (Stian
Halseth)
- When pcie_set_mps() changes MPS, update the value in the saved state so
a subsequent restore doesn't restore an invalid value (Niklas Cassel)
- Skip Target Speed quirk on clamped ports with no link (Maciej W.
Rozycki)
Driver binding:
- Assume control of portdrv-related features only when portdrv is
enabled, since we can't use them without portdrv (Kuppuswamy
Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
(Kuppuswamy Sathyanarayanan)
Error handling:
- Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
mention a device that no longer exists (Priyank Rathod)
- Fix aer_process_err_devices() leak when a device is recorded as an
error source purely by being mentioned in the Root Port Error Source
and the device is inaccessible or logged only masked errors (Priyank
Rathod)
ASPM:
- Disable ASPM when drivers request that, even if the OS doesn't own
ASPM; otherwise drivers do it on their own, which is worse (Ilpo
Järvinen)
Power management:
- Align hibernate poweroff flow with suspend flow for bridges so they can
be powered down at hibernate as they are for suspend (Mario
Limonciello)
- Restore BARs after powering up during enumeration to fix a regression
on devices that don't preserve state in D3hot (Keng-Yu Lin)
- Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting them
in D3hot takes down the whole switch (Imre Kaloz)
Power control:
- Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
Elder)
- Add DT documentation and pwrctrl driver support for TC9563 embedded
GPIO controller (Lorenzo Bianconi)
- Switch the tc9563 per-port reset to use the GPIO descriptor API instead
of direct regmap accesses (Lorenzo Bianconi)
- Only destroy devices created by pwrctrl core, so that when removing a
PCIe controller driver that uses pwrctrl, we don't remove devices
populated by another mechanism (Shawn Lin)
- Power off child devices on power-on failure (Lorenzo Bianconi)
PCIe native device hotplug:
- Make the 'pciehp_poll_mode' parameter read-only to prevent changes via
sysfs, which can cause errors when unbinding (Runyu Xiao)
Virtualization:
- Read SR-IOV VF Revision ID and Subsystem ID from VF instead of assuming
they're the same as VF 0; they may differ (Logan Odell)
- Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)
Peer-to-peer DMA:
- Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
bridges to allowlist (LeoLiu-oc)
- Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)
- Add Intel Haswell client host bridge to allowlist (Scott Lee)
- Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)
- Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
unmapping a BAR if registering another fails and (b) use after free of
p2p_pgmap (Leon Romanovsky)
- Wait for RCU readers before freeing state to avoid use-after-free of
pdev->p2pdma (Leon Romanovsky)
- Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
Romanovsky)
- Safely terminate ACS redirect lists to avoid out-of-bounds access to
the buffer (Leon Romanovsky)
- Silence 'Host bridge not in P2PDMA whitelist' warnings unless caller,
e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon Romanovsky)
Sysfs:
- Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes when
Device Name _DSM fails, not -1, which is interpreted as -EPERM
(Krzysztof Wilczyński)
- Return valid sysfs 'acpi_index' attribute even if the Device Name _DSM
returned an invalid 'label' (Krzysztof Wilczyński)
- Expose sysfs 'acpi_index' and 'label' based on whether the Device Name
_DSM returns valid data, not merely whether the _DSM is implemented
(Krzysztof Wilczyński)
- Avoid out-of-bounds reads of the label returned by the Device Name
_DSM, which is in UTF-16 characters, not bytes (Krzysztof Wilczyński)
- Reject unaligned resource I/O port accesses, which can oops on arm64
(Deepanshu Kartikey)
Endpoint framework:
- Pass the correct physical and virtual endpoint function numbers when
setting translation of inbound memory windows (Koichiro Den)
- Make embedded doorbell IRQ non-shared, since currently only the first
EPF can allocate doorbells (Koichiro Den)
- MSI doorbells currently target the first EPF attached to an EPC; let
other EPFs try the embedded doorbell instead of failing when they can't
use the MSI doorbell (Koichiro Den)
- Serialize scan of vNTB virtual PCI bus with other PCI topology changes
(Koichiro Den)
- Manage vNTB lifetimes to avoid leaking virtual devices and buses and
allow removal (Koichiro Den)
- Track vNTB link state from both sides so both see the same effective
link state (Koichiro Den)
- Configure vNTB MSI-X when supported to avoid IOMMU faults and failure
to deliver doorbell interrupts on RC (Koichiro Den)
APM X-Gene PCIe controller driver:
- Use devm for clocks so they're automatically disabled, unprepared, and
released if errors happen during probe (Yuho Choi)
ASPEED PCIe controller driver:
- Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
Zhenlong)
Broadcom iProc PCIe controller driver:
- Expose devm_pci_alloc_host_bridge_release() so drivers can share a devm
release function even if they don't need the device tree parsing done
by devm_pci_alloc_host_bridge() (Bjorn Helgaas)
- Request only the memory window from BCMA Enumeration ROM and warn if it
doesn't match the one in DT, which fixes an iproc-bcma probe failure
(Semih Baskan)
Broadcom STB PCIe controller driver:
- Replace bool properties for each SoC configuration with a u32 bitvector
and a BFLAG() helper (Jim Quinlan)
- Use a similar BQUIRK() helper to test various SoC quirks (Jim Quinlan)
Cadence PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY core
itself adds them (Vladimir Oltean)
- Return error (not success) from cdns_plat_pcie_probe() if
pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir Oltean)
- Correct the driver data pointer usage; previously .probe() stored
'struct cdns_plat_pcie *', but .shutdown() used the pointer as 'struct
cdns_pcie *', resulting in accessing garbage (Linmao Li)
ESWIN PCIe controller driver:
- Publish the platform driver MODULE_DEVICE_TABLE so the driver can be
autoloaded when built as a module (Pengpeng Hou)
Freescale i.MX6 PCIe controller driver:
- Fix resource and pwrctrl device leaks .probe() (Zhijian Han)
- Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
default 120 to 140 (Richard Zhu)
- Use dev_err_probe() in host init error path to silence -EPROBE_DEFER
messages (Alexander Stein)
- Avoid dereferencing NULL clock names when 'clocks' includes more
phandles than 'clock-names' has names (Rudi Heitbaum)
- Add suspend_poweroff flag so platforms like i.MX that power off RC
controllers during suspend can enter L2 so endpoints can get
PME_Turn_Off notifications before power loss (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
controllers on LX2160A (Vincent Jardin)
Intel VMD host bridge driver:
- Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
before write has completed, resulting in an nvme 30 second stall before
a QID timeout and possibly other similar problems (Rickey Bartlett)
- Flush DMA writes before handling MSI on Arrow Lake (Vladimir
Nedoshivin)
Marvell Aardvark PCIe controller driver:
- Disable PHY on probe failures (Myeonghun Pak)
Marvell MVEBU PCIe controller driver:
- Refcount child OF nodes during .probe() to make a concurrent OF overlay
removal safe (Krzysztof Kozlowski)
MediaTek PCIe controller driver:
- Find INTx DT property by 'interrupt-controller' name instead of
assuming it's the first child node (Zhengping Zhang)
MediaTek PCIe Gen3 controller driver:
- Fix a 64-bit type truncation in mtk_pcie_set_trans_table() to avoid
issues with windows above or larger than 4GB (Sreeraj S Kurup)
NVIDIA Tegra264 PCIe controller driver:
- Fix the Link Capabilities offset so we read the correct register (Bjorn
Helgaas)
Qualcomm PCIe controller driver:
- Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
resets used by downstream devices like USB controllers (Christopher
Obbard)
- Block accesses to downstream devices on link down to reduce a storm of
Completion Timeout AER interrupts (Qiang Yu)
- Skip system suspend/resume for firmware-managed PCIe, where firmware
manages clocks, regulators, resets, etc (Mrinmay Sarkar)
- Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
(Manivannan Sadhasivam)
- Deinitialize endpoint on remove (Guangshuo Li)
- Treat Root Port error recovery as successful even if link doesn't come
up after reset because the device was hot-unplugged (Konrad Dybcio)
- Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
indicating an external MSI controller (Ayiluri Naga Rashmi)
Renesas R-Car PCIe controller driver:
- Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
Vasut)
- Support PERST# via reset subsystem as well as the existing GPIO support
to prepare for R-Car Gen5 SoCs (Marek Vasut)
- Add DT and driver support for the R-Car Gen 5 X5H (R8A78000) PCIe Gen 4
core (Marek Vasut)
- Add Application/Local register reset DT description and driver support
for both host and endpoint mode (Marek Vasut)
- Add PM ops so controller works after suspend/resume (Marek Vasut)
Renesas RZ/G3S PCIe controller driver:
- Disable refclk on probe failure (Lad Prabhakar)
- Propagate platform_get_irq_byname() errors so probe deferral works
correctly (Lad Prabhakar)
- Tear down INTx handlers if subsequent initialization fails (Lad
Prabhakar)
- Add RZ/G3L (R9A08G046) DT and driver support (Biju Das)
Rockchip PCIe controller driver:
- Limit host and endpoint controllers to 2.5 GT/s since 5.0 GT/s is
unsafe per Rockchip (Geraldo Nascimento)
Synopsys DesignWare PCIe controller driver:
- Set DMA_BYPASS bit in outbound IATU CTRL2 register to avoid data
corruption if the iATU translates DMA engine transactions (Sumit Kumar)
- Use FIELD_PREP() to remove need for *_SHIFT definitions (Hans Zhang)
TI DRA7xx PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY core
itself adds them (Vladimir Oltean)
- Fix optional clock leak when .probe() fails by using
devm_clk_get_optional_enabled() (Felix Gu)
TI Keystone PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY core
itself adds them (Vladimir Oltean)
UltraRISC PCIe controller driver:
- Allow DWC drivers to skip outbound iATU setup if they don't need
translation between CPU and PCI addresses (Xincheng Zhang)
- Skip MEM outbound iATU setup on DP1000 (Xincheng Zhang)

- Add DT and driver support for optional PERST# for use in warm reset
scenarios (Sai Krishna Musham)
