Merge branch 'pci/misc' (2025-10-03 12:13:25 -0500)
----------------------------------------------------------------
Enumeration:
- Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that take
config space accessor functions; implement pci_find_capability(),
pci_find_ext_capability(), and dwc, dwc endpoint, and cadence
capability search interfaces with them (Hans Zhang)
- Leave parent unit address 0 in 'interrupt-map' so that when we build
devicetree nodes to describe PCI functions that contain multiple
peripherals, we can build this property even when interrupt controllers
lack 'reg' properties (Lorenzo Pieralisi)
- Add a Xeon 6 quirk to disable Extended Tags and limit Max Read Request
Size to 128B to avoid a performance issue (Ilpo Järvinen)
- Add sysfs 'serial_number' file to expose the Device Serial Number
(Matthew Wood)
- Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)
Resource management:
- Align m68k pcibios_enable_device() with other arches (Ilpo Järvinen)
- Remove sparc pcibios_enable_device() implementations that don't do
anything beyond what pci_enable_resources() does (Ilpo Järvinen)
- Remove mips pcibios_enable_resources() and use pci_enable_resources()
instead (Ilpo Järvinen)
- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:
- Leave non-claimed bridge windows disabled
- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices
- Preserve bridge window type when releasing the resource, since the
type is needed for reassignment
- Consolidate selection of bridge windows into two new interfaces,
pbus_select_window() and pbus_select_window_for_type(), so this is
done consistently
- Compute bridge window start and end earlier to avoid logging stale
information
MSI:
- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)
Error handling:
- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)
- If error recovery fails, emit FAILED_RECOVERY uevents for the devices,
not for the bridge leading to them; this makes them correspond to
BEGIN_RECOVERY uevents (Lukas Wunner)
- Align AER with EEH by calling err_handler.error_detected() callbacks to
notify drivers if error recovery fails (Lukas Wunner)
- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback;
this is earlier than before the err_handler.resume() callback (Lukas
Wunner)
- Emit a BEGIN_RECOVERY uevent when driver's err_handler.error_detected()
requests a reset, as well as when it says recovery is complete or can
be done without a reset (Niklas Schnelle)
- Align s390 with AER and EEH by emitting uevents during error recovery
(Niklas Schnelle)
- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the result
of err_handler.error_detected() (Niklas Schnelle)
- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES error
information identifies a device without an AER Capability (Breno
Leitao)
- Update error decoding and TLP Log printing for new errors in current
PCIe base spec (Lukas Wunner)
- Update error recovery documentation to match the current code and use
consistent nomenclature (Lukas Wunner)
ASPM:
- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM
This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)
- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)
Power management:
- If a device has already been disconnected, e.g., by a hotplug removal,
don't bother trying to resume it to D0 when detaching the driver; this
avoids annoying "Unable to change power state from D3cold to D0"
messages (Mario Limonciello)
- Ensure devices are powered up before config reads for 'max_link_width',
'current_link_speed', 'current_link_width', 'secondary_bus_number', and
'subordinate_bus_number' sysfs files; this prevents using invalid data
(~0) in drivers or lspci and, depending on how the PCIe controller
reports errors, may avoid error interrupts or crashes (Brian Norris)
Virtualization:
- Add rescan/remove locking when enabling/disabling SR-IOV, which avoids
list corruption on s390, where disabling SR-IOV also generates hotplug
events (Niklas Schnelle)
Peer-to-peer DMA:
- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)
Endpoint framework:
- Document sysfs interface for BAR assignment of vNTB endpoint functions
(Jerome Brunet)
- Fix array underflow in endpoint BAR test case (Dan Carpenter)
- Skip endpoint IRQ test if the IRQ is out of range to avoid false errors
(Christian Bruel)
- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)
- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)
- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)
- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)
- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)
- Handle errors in tegra194 BPMP transactions so we don't mistakenly skip
future PERST# assertion (Vidya Sagar)
AMD MDB PCIe controller driver:
- Update DT binding example to separate PERST# to a Root Port stanza to
make multiple Root Ports possible in the future (Sai Krishna Musham)
- Add driver support for PERST# being described in a Root Port stanza,
falling back to the host bridge if not found there (Sai Krishna Musham)
Freescale i.MX6 PCIe controller driver:
- Enable the 3.3V Vaux supply if available so devices can request wakeup
with either Beacon or WAKE# (Richard Zhu)
MediaTek PCIe Gen3 controller driver:
- Add optional sys clock ready time setting to avoid sys_clk_rdy signal
glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)
- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)
NVIDIA Tegra PCIe controller driver:
- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)
- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
Qualcomm PCIe controller driver:
- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)
- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused probe
failures (Krishna Chaitanya Chundru)
- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)
- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root Port
node or the host bridge node (Manivannan Sadhasivam)
- Fetch and map the ELBI register space in the DWC core rather than in
each driver individually (Krishna Chaitanya Chundru)
- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG Shift
Feature' and use this in the qcom driver (Krishna Chaitanya Chundru)
- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)
- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)
Renesas R-Car PCIe controller driver:
- Fix a typo that prevented correct PHY initialization (Marek Vasut)
- Add a missing 1ms delay after PWR reset assertion as required by the
V4H manual (Marek Vasut)
- Assure reset has completed before DBI access to avoid SError (Marek
Vasut)
- Fix inverted PHY initialization check, which sometimes led to timeouts
and failure to start the controller (Marek Vasut)
- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain() (Claudiu
Beznea)
- Drop the spinlock protecting the PMSR register; it's no longer required
since pci_lock already serializes accesses (Marek Vasut)
- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
SOPHGO PCIe controller driver:
- Check for existence of struct cdns_pcie.ops before using it to allow
Cadence drivers that don't need to supply ops (Chen Wang)
- Add DT binding and driver for the SOPHGO SG2042 PCIe controller (Chen
Wang)
STMicroelectronics STM32MP25 PCIe controller driver:
- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)
- Add pinctrl_pm_select_init_state() for use by stm32 driver, which needs
it during resume (Christian Bruel)
- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)
Synopsys DesignWare PCIe controller driver:
- Add support for x16 in devicetree 'num-lanes' property (Konrad Dybcio)
- Verify that if DT specifies a single IRQ for all eDMA channels, it is
named 'dma' (Niklas Cassel)
TI J721E PCIe driver:
- Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
Vadapalli)
- Power controller off before configuring the glue layer so the
controller latches the correct values on power-on (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)
- Add Peripheral Virtualization Unit (PVU), which restricts DMA from PCIe
devices to specific regions of host memory, to the ti,am65 binding (Jan
Kiszka)
Xilinx NWL PCIe controller driver:
- Clear bootloader E_ECAM_CONTROL before merging in the new driver value
to avoid writing invalid values (Jani Nurminen)
