Merge branch 'pci/typos' (2024-11-25 13:41:00 -0600)
NB:
- Rebased this morning to remove duplicate commits. Result is git
diff-identical to 0f3d0b32cf72, which has been in linux-next since
Nov 22.
- Conflict in drivers/pci/probe.c between existing 1d59d474e1cb ("PCI:
Hold rescan lock while adding devices during host probe") and new
dc421bb3c0db ("PCI: Enable runtime PM of the host bridge").
- Conflict in drivers/pci/pwrctrl/pci-pwrctrl-pwrseq.c between existing
ad783b9f8e78 ("PCI/pwrctl: Abandon QCom WCN probe on pre-pwrseq
device-trees") and new 086bf79a4d45 ("PCI/pwrctrl: Rename pwrctl files
to pwrctrl") and e826ea4c7f26 ("PCI/pwrctrl: Rename pwrctrl functions
and structures"). Note the names in pci_pwrctrl_pwrseq_of_match[]
that need to be updated but aren't flagged as a conflict.
----------------------------------------------------------------
Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers
can't stop a device multiple times, even as we migrate from the global
pci_rescan_remove_lock to finer-grained locking (Keith Busch)
- Improve pci_walk_bus() implementation by making it recursive and moving
locking up to avoid need for a 'locked' parameter (Keith Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by the
PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence 'trustworthy'
by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface'
ACPI properties are not quite enough (Esther Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties when
building dynamic DT nodes so systems where PCI and CPU addresses differ
work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce redundancy
(Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish the
conversion from returning 'int' to being 'void' (Sergio Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request all
BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and release
a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when there
was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as
required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate() to
create pwrctl platform devices so we can control it based on the child
nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power supply
property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a race
where pwrctl could change device power state while the PCI driver was
active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node() instead of
searching all children of the parent (Manivannan Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into pcie_lbms_seen(),
where it can be shared between the bandwidth controller and quirks that
use it to help retrain failed links (Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address the
reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers can
manage PCIe Link speed based on thermal or other constraints (Ilpo
Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the existing
thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function device
where function 0 has a management console interface to enable/disable
and provision various personalities for the other functions (Shijith
Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and doesn't
handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR
were set, so the functions can be in independent IOMMU groups (Mengyuan
Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a request
to the mailbox to avoid failures if the mailbox is still busy from a
previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if the
requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle
controller-specific size and alignment constraints, and add test cases
to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe
DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT
property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when removing
the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware erratum
that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of clocks
for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire Root
Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the host
to the notifier that tells us the host has deasserted PERST#, when
refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a previous
commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the host
to the notifier that tells us the host has deasserted PERST#, when
refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP v5.80a
and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml
DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom
platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the link
comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to
support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang
Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align
value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead of
searching for it, and verify that the address was mapped (Damien Le
Moal)
- When mapping an endpoint window, verify that the address hasn't been
mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to rockchip_pcie_ep_get_resources()
for consistency with similar DT interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do it
only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it (Damien
Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated resets
and start link training after PERST# is deasserted (Damien Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match an
ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us),
before deasserting PERST# to ensure power and refclk are stable
(Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex
mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we can do
(Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)
- Fix incorrect printf format specifiers in pcitest (Luo Yifan)
