Merge branch 'pci/misc' (2026-06-23 17:32:24 -0500)
----------------------------------------------------------------
Enumeration:
- Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked around
a WiFi device defect; use a quirk or boot-time "pci=pcie_bus_tune_*"
kernel parameter instead (Bjorn Helgaas)
- Always lift 2.5GT/s restriction in PCIe failed link retraining to avoid
clamping a link to 2.5GT/s after hot-plug changes the device (Maciej W.
Rozycki)
- Request bus reassignment when not probe-only to fix an enumeration
regression on Marvell CN106XX and possibly other DT-based systems
(Ratheesh Kannoth)
- Fix procfs race between pci_proc_init() and pci_bus_add_device() that
resulted in 'proc_dir_entry ... already registered' warnings and
pointer corruption (Krzysztof Wilczyński)
- Fix sysfs race that causes 'duplicate filename' warnings and boot
panics by converting PCI resource files to static attributes (Krzysztof
Wilczyński)
- Expose sysfs 'resourceN_resize' attributes only on platforms with PCI
mmap (Krzysztof Wilczyński)
- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize' attributes
(Krzysztof Wilczyński)
- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
mmap path to match the generic path (Krzysztof Wilczyński)
- Use kstrtobool() to parse the 'rom' attribute input to avoid the
unexpected behavior of enabling the ROM when writing '0' with no
trailing newline (Krzysztof Wilczyński)
Resource management:
- Improve resource claim logging for debuggability (Ilpo Järvinen)
- Clean up several uses of const parameters (Ilpo Järvinen)
- Check option ROM header signatures and lengths before accessing to
avoid page faults and alignment faults (Guixin Liu)
ASPM:
- Don't reconfigure ASPM when entering low-power D-state; only do it when
returning back to D0 (Carlos Bilbao)
Power management:
- During suspend, set power state to 'unknown' for all devices, not just
those with drivers (Lukas Wunner)
- Skip restoring Resizable BARs and VF Resizable BARs if device doesn't
respond to config reads, to avoid invalid array accesses (Marco
Nenciarini)
- Add pci_suspend_retains_context() so drivers can tell whether devices
retain internal state across suspend/resume, since some platforms reset
devices on suspend; use this in nvme to avoid issues on Qcom RCs
(Manivannan Sadhasivam)
Power control:
- Only to power on/off devices that actually support power control to
avoid poking at incompatible devices mentioned in DT (Manivannan
Sadhasivam)
Virtualization and resets:
- Log device readiness timeouts as errors, not warnings, because the
device is likely unusable in this case (Bjorn Helgaas)
- Wait for device readiness after soft reset (D3hot -> D0uninitialized
transition), when the device may respond with Request Retry Status
(RRS) if it needs more time to initialize (Bjorn Helgaas)
- Drop unnecessary retries when restoring BARs because resets should now
already include all required delays (Lukas Wunner)
- Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
terminates uncleanly (Jose Ignacio Tornos Martinez)
- Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems, which
seem not to support it correctly (Jose Ignacio Tornos Martinez)
Peer-to-peer DMA:
- Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g., s390
ISM BARs (Matt Evans)
- Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)
Endpoint framework:
- Add endpoint controller APIs for use by function drivers to discover
auxiliary blocks like DMA engines (Koichiro Den)
- Remember DesignWare eDMA engine base/size and expose them via the EPC
aux-resource API (Koichiro Den)
- Add endpoint embedded doorbell fallback, used if MSI allocation fails
(Koichiro Den)
- Validate BAR index and remove dead BAR read in endpoint doorbell test
(Carlos Bilbao)
- Unwind MSI/MSI-X vectors if NTB initialization fails part-way through
(Koichiro Den)
- Cache sleepable pci_irq_vector() value at ISR setup to avoid calling it
from hardirq context (Koichiro Den)
- Call sleepable pci_epc_raise_irq() from a work item instead of atomic
context, e.g., when setting bits in NTB peer doorbells in the
ntb_peer_db_set() path (Koichiro Den)
- Report 0-based vNTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Prevent configfs writes to vNTB db_count and other values that are
already in use after EPC attach (Koichiro Den)
- Account for vNTB db_valid reserved slots (link event 0 and historically
skipped slot 1) so they don't appear as valid doorbells (Koichiro Den)
- Implement vNTB .db_vector_count()/mask() for doorbells so clients can
use multiple vectors and avoid thundering herds (Koichiro Den)
- Report 0-based NTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Fix doorbell bitmask and IRQ vector handling to clear only specified
bits, use the correct vector for non-contiguous Linux IRQ numbers, and
validate incoming vectors (Koichiro Den)
- Implement NTB .db_vector_count()/mask() for doorbells so clients can
use multiple vectors (Koichiro Den)
Native PCIe controller infrastructure:
- Add pci_host_common_link_train_delay() for the mandatory delay after
> 5GT/s Link training completes and use it for cadence HPA, j721e, LGA;
dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)
- Protect root bus removal with rescan lock in altera, brcmstb, cadence,
dwc, iproc, mediatek, plda, rockchip to prevent use-after-free or
crashes when racing with sysfs rescan or hotplug (Hans Zhang)
- Add pci_host_common_parse_ports() for use by any native driver to parse
Root Port properties (per-Link features like width, speed, PHY, power
and reset control, etc should be described in Root Port stanzas, not
the host bridge; currently only reset GPIOs implemented) (Sherry Sun)
New native PCIe controller drivers:
- Add DT binding and driver for UltraRISC DP1000 PCIe controller
(Xincheng Zhang, Jia Wang)

(Shuvam Pandey)
- Add .remove() callback to deinitialize the host bridge and power off

Broadcom STB PCIe controller driver:
- No change, but products using certain WiFi devices may be affected by
removal of CONFIG_PCIE_BUS_* (see above)
Freescale i.MX6 PCIe controller driver:
- Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
functions (Richard Zhu)
- Assert PERST# before enabling regulators to ensure that even if power
is enabled, endpoint stays inactive until REFCLK is stable (Sherry Sun)
- Parse reset properties in Root Port nodes (falling back to host bridge)
to help support Key E connectors and the pwrctrl framework (Sherry Sun)
- Configure i.MX95 REF_USE_PAD before PHY reset (Richard Zhu)
- Assert i.MX95 ref_clk_en after reference clock stabilizes (Richard Zhu)
- Integrate new pwrctrl API for DTs with Root Port-level power supplies
(Sherry Sun)
Intel Gateway PCIe controller driver:
- Enable clock before PHY init for correct ordering (Florian Eckert)
- Add .start_link() callback so the driver works again (Florian Eckert)
- Stop overwriting the ATU base address discovered by
dw_pcie_get_resources() (Florian Eckert)
- Add DT 'atu' region since this is hardware-specific, and fall back to
driver default if lacking (Florian Eckert)
Loongson PCIe controller driver:
- Ignore downstream devices only on internal bridges to avoid Loongson
hardware issue (Rong Zhang)
- Quirk old Loongson-3C6000 bridges that advertise incorrect supported

virt_to_phys() (Manivannan Sadhasivam)
- Add EcoNet EN7528 to DT binding (Caleb James DeLisle)
MediaTek PCIe Gen3 controller driver:
- Deassert PCIE_PHY_RSTB so REFCLK is stable for at least 100ms
(PCIE_T_PVPERL_MS) before deasserting PERST# (Jian Yang)
- Add .shutdown() to assert PERST# before powering down device (Jian
Yang)
- Do full device power down on removal, including asserting PERST#, when
removing driver (Chen-Yu Tsai)
- Fix a 'failed to create pwrctrl devices' error message that was
inadvertently skipped (Chen-Yu Tsai)

devices are already in D3hot and wakeup-enabled devices are capable of
generating PME from D3cold (Krishna Chaitanya Chundru)

DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya Chundru)
- Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to avoid
power leakage (Krishna Chaitanya Chundru)
- Decide whether suspend should put the link in L2 and power down using

is enabled (Krishna Chaitanya Chundru)
- Add qcom D3cold support to tear down interconnect bandwidth and OPP
votes (Krishna Chaitanya Chundru)
- Handle unsupported mixed PERST#/PHY DT configurations, e.g., PHY in RP
node while PERST# is in the RC node, but warn about the DT issue (Qiang

- Add RZ/V2N DT support (Lad Prabhakar)
SOPHGO PCIe controller driver:
- Add 'dma-coherent' DT property for sg2042-pcie driver (Han Gao)

- Apply ECRC TLP Digest workaround for all DesignWare cores prior to
5.10a, not just 4.90a and 5.00a (Manikanta Maddireddy)
