hwmon: (pmbus/tps25990) Add initial support
Add initial support for the Texas Instruments TPS25990 eFuse. This adds the basic PMBUS telemetry support for the device. From Karol Przybylski: The tps25990_read_word_data function contains a block of unreachable code caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case. Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately exits the function, making the next lines unreachable. This patch removes the return statement, leaving the expected handling.

firmware: cs_dsp: Add mock regmap for KUnit testing
Add a mock regmap implementation to act as a simulated DSP for KUnit testing. This is built as a utility module so that it could be used by clients of cs_dsp to create a mock "DSP" for their own testing. cs_dsp interacts with the DSP only through registers. Most of the register space of the DSP is RAM. ADSP cores have a small set of control registers. HALO Core DSPs have a much larger set of control registers but only a small subset are used. Most writes are "blind" in the sense that cs_dsp does not expect to receive any sort of response from the DSP. So there isn't any need to emulate a "DSP", only a set of registers that can be written and read back. The idea of the mock regmap is to use the cache to accumulate writes which can then be tested against the values that are expected to be in the registers. Stray writes can be detected by dropping the cache entries for all addresses that should have been written and then issuing a regcache_sync(). If this causes bus writes it means there were writes to unexpected registers.

lib: packing: add pack_fields() and unpack_fields()
This is new API which caters to the following requirements: - Pack or unpack a large number of fields to/from a buffer with a small code footprint. The current alternative is to open-code a large number of calls to pack() and unpack(), or to use packing() to reduce that number to half. But packing() is not const-correct. - Use unpacked numbers stored in variables smaller than u64. This reduces the rodata footprint of the stored field arrays. - Perform error checking at compile time, rather than runtime, and return void from the API functions. Because the C preprocessor can't generate variable length code (loops), this is a bit tricky to do with macros. To handle this, implement macros which sanity check the packed field definitions based on their size. Finally, a single macro with a chain of __builtin_choose_expr() is used to select the appropriate macros. We enforce the use of ascending or descending order to avoid O(N^2) scaling when checking for overlap. Note that the macros are written with care to ensure that the compilers can correctly evaluate the resulting code at compile time. In particular, care was taken with avoiding too many nested statement expressions. Nested statement expressions trip up some compilers, especially when passing down variables created in previous statement expressions. There are two key design choices intended to keep the overall macro code size small. First, the definition of each CHECK_PACKED_FIELDS_N macro is implemented recursively, by calling the N-1 macro. This avoids needing the code to repeat multiple times. Second, the CHECK_PACKED_FIELD macro enforces that the fields in the array are sorted in order. This allows checking for overlap only with neighboring fields, rather than the general overlap case where each field would need to be checked against other fields. The overlap checks use the first two fields to determine the order of the remaining fields, thus allowing either ascending or descending order. This enables drivers the flexibility to keep the fields ordered in which ever order most naturally fits their hardware design and its associated documentation. The CHECK_PACKED_FIELDS macro is directly called from within pack_fields and unpack_fields, ensuring that all drivers using the API receive the benefits of the compile-time checks. Users do not need to directly call any of the macros directly. The CHECK_PACKED_FIELDS and its helper macros CHECK_PACKED_FIELDS_(0..50) are generated using a simple C program in scripts/gen_packed_field_checks.c This program can be compiled on demand and executed to generate the macro code in include/linux/packing.h. This will aid in the event that a driver needs more than 50 fields. The generator can be updated with a new size, and used to update the packing.h header file. In practice, the ice driver will need to support 27 fields, and the sja1105 driver will need to support 0 fields. This on-demand generation avoids the need to modify Kbuild. We do not anticipate the maximum number of fields to grow very often. - Reduced rodata footprint for the storage of the packed field arrays. To that end, we have struct packed_field_u8 and packed_field_u16, which define the fields with the associated type. More can be added as needed (unlikely for now). On these types, the same generic pack_fields() and unpack_fields() API can be used, thanks to the new C11 _Generic() selection feature, which can call pack_fields_u8() or pack_fields_16(), depending on the type of the "fields" array - a simplistic form of polymorphism. It is evaluated at compile time which function will actually be called. Over time, packing() is expected to be completely replaced either with pack() or with pack_fields().

net: lan969x: fix cyclic dependency reported by depmod
Depmod reports a cyclic dependency between modules sparx5-switch.ko and
lan969x-switch.ko:
depmod: ERROR: Cycle detected: lan969x_switch -> sparx5_switch -> lan969x_switch
depmod: ERROR: Found 2 modules in dependency cycles!
make[2]: *** [scripts/Makefile.modinst:132: depmod] Error 1
make: *** [Makefile:224: __sub-make] Error 2
This makes sense, as they both require symbols from each other.
Fix this by compiling lan969x support into the sparx5-switch.ko module.
In order to do this, in a sensible way, we move the lan969x/ dir into
the sparx5/ dir and do some code cleanup of code that is no longer
required.
After this patch, depmod will no longer complain, as lan969x support is
compiled into the sparx5-swicth.ko module, and can no longer be compiled
as a standalone module.

hyperv: Add new Hyper-V headers in include/hyperv
These headers contain definitions for regular Hyper-V guests (as in hyperv-tlfs.h), as well as interfaces for more privileged guests like the root partition (aka Dom0). These files are derived from headers exported from Hyper-V, rather than being derived from the TLFS document. (Although, to preserve compatibility with existing Linux code, some definitions are copied directly from hyperv-tlfs.h too). The new files follow a naming convention according to their original use: - hdk "host development kit" - gdk "guest development kit" With postfix "_mini" implying userspace-only headers, and "_ext" for extended hypercalls. The use of multiple files and their original names is primarily to keep the provenance of exactly where they came from in Hyper-V code, which is helpful for manual maintenance and extension of these definitions. Microsoft maintainers importing new definitions should take care to put them in the right file. However, Linux kernel code that uses any of the definitions need not be aware of the multiple files or assign any meaning to the new names. Linux kernel code should always just include hvhdk.h Note the new headers contain both arm64 and x86_64 definitions. Some are guarded by #ifdefs, and some are instead prefixed with the architecture, e.g. hv_x64_*. These conventions are kept from Hyper-V code as another tactic to simplify the process of importing and maintaining the definitions, rather than splitting them up into their own files in arch/x86/ and arch/arm64/. These headers are a step toward importing headers directly from Hyper-V in the future, similar to Xen public files in include/xen/interface/.

arm64 fixes for 6.13-rc2:
- MTE/hugetlbfs:
- Set VM_MTE_ALLOWED in the arch code and remove it from the core code
for hugetlbfs mappings
- Fix copy_highpage() warning when the source is a huge page but not
MTE tagged, taking the wrong small page path
- drivers/virt/coco:
- Add the pKVM and Arm CCA drivers under the arm64 maintainership
- Fix the pkvm driver to fall back to ioremap() (and warn) if the
MMIO_GUARD hypercall fails
- Keep the Arm CCA driver default 'n' rather than 'm'
- A series of fixes for the arm64 ptrace() implementation, potentially
leading to the kernel consuming uninitialised stack variables when
PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and ZONE_DMA
is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a call
to page_to_phys() (from patch_map()) which checks pfn_valid() before
vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI ops
when the kernel assumes 8-bit ASIDs but running under a hypervisor on
a system that implements 16-bit ASIDs (found running Linux under
Parallels on Apple M4)
- ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it is
using the same SMMU PMCG as HIP09 and suffers from the same errata
- Add GCS to cpucap_is_possible(), missed in the recent merge

i2c-for-6.13-rc1-part3
core: add of based component probing Some devices are designed and manufactured with some components having multiple drop-in replacement options. These components are often connected to the mainboard via ribbon cables, having the same signals and pin assignments across all options. These may include the display panel and touchscreen on laptops and tablets, and the trackpad on laptops. Sometimes which component option is used in a particular device can be detected by some firmware provided identifier, other times that information is not available, and the kernel has to try to probe each device. Instead of a delicate dance between drivers and device tree quirks, this change introduces a simple I2C component probe function. For a given class of devices on the same I2C bus, it will go through all of them, doing a simple I2C read transfer and see which one of them responds. It will then enable the device that responds. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmdMOCwACgkQFA3kzBSg KbaLWQ//e+29c9Trh+Typ6YCknuCFmM12xNUEPgce93EldERZjfCsdlHEchJnjEe RX5Mw+UxT7NqFUD6G2YQQw35LMj/PDws4Q/q3OwAvurj2PqoKEGIbdTxUEbGrLtT aYRUjGoqjPk3gAkqfKEQp8X8bvqKJfQ/xeXcZyy7Ij8xPU1LC/W6So4vpZA7oZkZ UfwrUXu2NM/DKfLATeSH3vnlBrrpco9BdjImDanP8BpuYHQ0aNt7IToDytd3/rLZ WKQPbHqVzzBUHm8Tf+DTyeVtII/ID078z+RW7htPrzPtzhVu2DN56w3z7/+EsVIy XKb1PiJo5HlFev4gxhIcUgf8L5JYE8MyU8eeRWAcDObiBYVcSP34P7Xoykczjuq9 22IFNSdaqMVdigo9v4p7U99fVjoi3oUqIVsSb2HkmND8bPw3+jtyq1GxTFvTeOw8 EVJGuGjYrPiko26zNgK/WZaumpB+fsH7uRioSb1ejlSQk0BcNv4YqjYaMx9aT7Xj +zF7luuxpkWTkPCjk57GX55K/BFzkA9jhJdKqjImBS+Q9Rn3k5bHyRdNPUDIeWs0 Yl5dhg6QbLHyuPC2R/hJiV6X4uFloH9+Oh99T3lLzcVNc2mllPQDN9F4I8q5nWB8 Eq5U95fnegfdVkiWnbNCnTCux/mypm35Gx46BffTiAJL2U9pSIE= =MAxU -----END PGP SIGNATURE----- Merge tag 'i2c-for-6.13-rc1-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c component probing support from Wolfram Sang: "Add OF component probing.

Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
subsystem updates for 6.13-rc1. Sorry for doing this at the end of the
merge window, conference and holiday travel got in the way on my side
(hence the 5am pull request emails...)
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible. I think this is the tipping point,
expect to see way more rust drivers going forward now that these
bindings are present. Next merge window hopefully we will have pci
and platform drivers working, which will fully enable almost all
driver subsystems to start accepting (or at least getting) rust
drivers. This is the end result of a lot of work from a lot of
people, congrats to all of them for getting this far, you've proved
many of us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes
- loads of other small char/misc/etc driver updates and additions,
full details in the shortlog.
Note, there is a semi-hairy rust merge conflict when pulling this. The
resolution has been in linux-next for a while and can be seen here:
https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
All of these have been in linux-next for a while, with no other reported
issues other than that merge conflict.

Staging driver changes for 6.13-rc1
Here is the big set of staging driver changes for 6.13-rc1.
Lots of changes this merge cycle, drivers removed and drivers added.
Highlights include:
- removals of the following staging drivers due to no forward progress
and no one having either the hardware or the time/energy to deal
with them anymore:
- fieldbus
- gdm724x
- olpc_dcon
- rtl8712
- rts5208
- vt6655
- vt6656
If anyone has this hardware and wants to work on the drivers, it can
be an easy revert to get them back.
- addition of the gpib driver subsystem. Lots of drivers for
really old and semi-old interfaces to lab equipments. We expect lots
of churn in these drivers as they get cleaned up to "working" order.
These were added at the request of a user and the maintainer/author
of them is helping out with the effort
- loads and loads of tiny coding style cleanups for almost all staging
drivers. Too many to list, see the shortlog for details.
Note, this pull request contains a portion of the wireless tree, as the
removal of some of the staging wifi drivers came in through there to
coordinate things. These should already be in your tree already, so the
diffstat will (and should) look different when you do your merge.
All of these have been in linux-next for a very long time with no
reported issues.

i2c: Introduce OF component probe function
Some devices are designed and manufactured with some components having multiple drop-in replacement options. These components are often connected to the mainboard via ribbon cables, having the same signals and pin assignments across all options. These may include the display panel and touchscreen on laptops and tablets, and the trackpad on laptops. Sometimes which component option is used in a particular device can be detected by some firmware provided identifier, other times that information is not available, and the kernel has to try to probe each device. This change attempts to make the "probe each device" case cleaner. The current approach is to have all options added and enabled in the device tree. The kernel would then bind each device and run each driver's probe function. This works, but has been broken before due to the introduction of asynchronous probing, causing multiple instances requesting "shared" resources, such as pinmuxes, GPIO pins, interrupt lines, at the same time, with only one instance succeeding. Work arounds for these include moving the pinmux to the parent I2C controller, using GPIO hogs or pinmux settings to keep the GPIO pins in some fixed configuration, and requesting the interrupt line very late. Such configurations can be seen on the MT8183 Krane Chromebook tablets, and the Qualcomm sc8280xp-based Lenovo Thinkpad 13S. Instead of this delicate dance between drivers and device tree quirks, this change introduces a simple I2C component probe function. For a given class of devices on the same I2C bus, it will go through all of them, doing a simple I2C read transfer and see which one of them responds. It will then enable the device that responds. This requires some minor modifications in the existing device tree. The status for all the device nodes for the component options must be set to "fail-needs-probe". This makes it clear that some mechanism is needed to enable one of them, and also prevents the prober and device drivers running at the same time.

Pull PCI updates from Bjorn Helgaas:
"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)

Like AutoFDO, Propeller uses hardware sampling to gather information about the frequency of execution of different code paths within a binary. This information is then used to guide the compiler's optimization decisions, resulting in a more efficient binary. The support requires a Clang compiler LLVM 19 or later, and the create_llvm_prof tool (https://github.com/google/autofdo/releases/tag/v0.30.1). This commit is limited to x86 platforms that support PMU features like LBR on Intel machines and AMD Zen3 BRS. Here is an example workflow for building an AutoFDO+Propeller optimized kernel: 1) Build the kernel on the host machine, with AutoFDO and Propeller build config CONFIG_AUTOFDO_CLANG=y CONFIG_PROPELLER_CLANG=y then $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile> “<autofdo_profile>” is the profile collected when doing a non-Propeller AutoFDO build. This step builds a kernel that has the same optimization level as AutoFDO, plus a metadata section that records basic block information. This kernel image runs as fast as an AutoFDO optimized kernel. 2) Install the kernel on test/production machines. 3) Run the load tests. The '-c' option in perf specifies the sample event period. We suggest using a suitable prime number, like 500009, for this purpose. For Intel platforms: $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> \ -o <perf_file> -- <loadtest> For AMD platforms: The supported system are: Zen3 with BRS, or Zen4 with amd_lbr_v2 # To see if Zen3 support LBR: $ cat proc/cpuinfo | grep " brs" # To see if Zen4 support LBR: $ cat proc/cpuinfo | grep amd_lbr_v2 # If the result is yes, then collect the profile using: $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a \ -N -b -c <count> -o <perf_file> -- <loadtest> 4) (Optional) Download the raw perf file to the host machine. 5) Generate Propeller profile: $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> \ --format=propeller --propeller_output_module_name \ --out=<propeller_profile_prefix>_cc_profile.txt \ --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt “create_llvm_prof” is the profile conversion tool, and a prebuilt binary for linux can be found on https://github.com/google/autofdo/releases/tag/v0.30.1 (can also build from source). "<propeller_profile_prefix>" can be something like "/home/user/dir/any_string". This command generates a pair of Propeller profiles: "<propeller_profile_prefix>_cc_profile.txt" and "<propeller_profile_prefix>_ld_profile.txt". 6) Rebuild the kernel using the AutoFDO and Propeller profile files. CONFIG_AUTOFDO_CLANG=y CONFIG_PROPELLER_CLANG=y and $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile> \ CLANG_PROPELLER_PROFILE_PREFIX=<propeller_profile_prefix> Co-developed-by: Han Shen <shenhan@google.com> Signed-off-by: Han Shen <shenhan@google.com> Signed-off-by: Rong Xu <xur@google.com> Suggested-by: Sriraman Tallam <tmsriram@google.com> Suggested-by: Krzysztof Pszeniczny <kpszeniczny@google.com> Suggested-by: Nick Desaulniers <ndesaulniers@google.com> Suggested-by: Stephane Eranian <eranian@google.com> Tested-by: Yonghong Song <yonghong.song@linux.dev> Tested-by: Nathan Chancellor <nathan@kernel.org> Reviewed-by: Kees Cook <kees@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

Rust changes for v6.13
Toolchain and infrastructure:
- Enable a series of lints, including safety-related ones, e.g. the
compiler will now warn about missing safety comments, as well as
unnecessary ones. How safety documentation is organized is a frequent
source of review comments, thus having the compiler guide new
developers on where they are expected (and where not) is very nice.
- Start using '#[expect]': an interesting feature in Rust (stabilized
in 1.81.0) that makes the compiler warn if an expected warning was
_not_ emitted. This is useful to avoid forgetting cleaning up locally
ignored diagnostics ('#[allow]'s).
- Introduce '.clippy.toml' configuration file for Clippy, the Rust
linter, which will allow us to tweak its behaviour. For instance, our
first use cases are declaring a disallowed macro and, more
importantly, enabling the checking of private items.
- Lints-related fixes and cleanups related to the items above.
- Migrate from 'receiver_trait' to 'arbitrary_self_types': to get the
kernel into stable Rust, one of the major pieces of the puzzle is the
support to write custom types that can be used as 'self', i.e. as
receivers, since the kernel needs to write types such as 'Arc' that
common userspace Rust would not. 'arbitrary_self_types' has been
accepted to become stable, and this is one of the steps required to
get there.
- Remove usage of the 'new_uninit' unstable feature.
- Use custom C FFI types. Includes a new 'ffi' crate to contain our
custom mapping, instead of using the standard library 'core::ffi'
one. The actual remapping will be introduced in a later cycle.
- Map '__kernel_{size_t,ssize_t,ptrdiff_t}' to 'usize'/'isize' instead
of 32/64-bit integers.
- Fix 'size_t' in bindgen generated prototypes of C builtins.
- Warn on bindgen < 0.69.5 and libclang >= 19.1 due to a double issue
in the projects, which we managed to trigger with the upcoming
tracepoint support. It includes a build test since some distributions
backported the fix (e.g. Debian -- thanks!). All major distributions
we list should be now OK except Ubuntu non-LTS.
'macros' crate:
- Adapt the build system to be able run the doctests there too; and
clean up and enable the corresponding doctests.
'kernel' crate:
- Add 'alloc' module with generic kernel allocator support and remove
the dependency on the Rust standard library 'alloc' and the extension
traits we used to provide fallible methods with flags.
Add the 'Allocator' trait and its implementations '{K,V,KV}malloc'.
Add the 'Box' type (a heap allocation for a single value of type 'T'
that is also generic over an allocator and considers the kernel's GFP
flags) and its shorthand aliases '{K,V,KV}Box'. Add 'ArrayLayout'
type. Add 'Vec' (a contiguous growable array type) and its shorthand
aliases '{K,V,KV}Vec', including iterator support.
For instance, now we may write code such as:
let mut v = KVec::new();
v.push(1, GFP_KERNEL)?;
assert_eq!(&v, &[1]);
Treewide, move as well old users to these new types.
- 'sync' module: add global lock support, including the
'GlobalLockBackend' trait; the 'Global{Lock,Guard,LockedBy}' types
and the 'global_lock!' macro. Add the 'Lock::try_lock' method.
- 'error' module: optimize 'Error' type to use 'NonZeroI32' and make
conversion functions public.
- 'page' module: add 'page_align' function.
- Add 'transmute' module with the existing 'FromBytes' and 'AsBytes'
traits.
- 'block::mq::request' module: improve rendered documentation.
- 'types' module: extend 'Opaque' type documentation and add simple
examples for the 'Either' types.
drm/panic:
- Clean up a series of Clippy warnings.
Documentation:
- Add coding guidelines for lints and the '#[expect]' feature.
- Add Ubuntu to the list of distributions in the Quick Start guide.
MAINTAINERS:
- Add Danilo Krummrich as maintainer of the new 'alloc' module.
And a few other small cleanups and fixes.

NFSD 6.13 Release Notes
Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation. This improvement is intended to increase the rate at which NFSD can safely recall NFSv4 delegations from clients, to avoid the need to revoke them. Revoking requires a slow state recovery process. A wide variety of bug fixes and other incremental improvements make up the bulk of commits in this series. As always I am grateful to the NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmdEgLQACgkQM2qzM29m f5cwmg/9HcfG7blepU/2qNHopzSYRO5vZw1YNJQ5/Wi3bmqIea83lf8OcCY1G/aj 6K+jnenzHrwfhaA4u7N2FPXPVl8sPSMuOrJXY5zC4yE5QnIbranjcyEW5l5zlj3n ukkTYQgjUsKre3pHlvn3JmDHfUhNPEfzirsJeorP7DS3omne+OFA1LNncNP6emRu h0aEC6EJ43zUkYiz9nZYqPwIAwrUIA0WOrvVnq7vsi6gR4/Muk7nS+X/y4qFjli3 9enVskEv8sFmmOAIMK3CHJq+exEeKtKEKUuYkD23QgPt2R4+IwqS70o9IM/S1ypf APiv958BIhxm/SwUn1IjoxIckTB5EdksMxU5/4qGr1ZxprPG4/ruKO80BkrxLzW2 n1HmJ4ZNnpWPQvHN7RQ0WOsPNzL8byxJbGr1bpNgU4AGXnTFWPrAnB6juiyX4xb+ YNfgkQGDY79o7r1OJ5UUdCyx0QBSnaLNACTGm2u2FpI/ukMFPdrWIE99QbBgSe1p MgWaiPwSY+9crFfGPJeQ4t6/siRAec6L3RO9KT9Epcd2S7/Uts3NXYRdJfwZ+Qza TkPY2bm7T/WCcMhW7DN372hqgfRHPWOf4tacJ1Tob+As1d6p6qXEX2zi6piCCOLj dmTVDSVPClRXt8YigF9WqosyWv1jUzSnh9ne+eYPBpj93Ag2YBY= =wBvS -----END PGP SIGNATURE----- Merge tag 'nfsd-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation.

i2c-for-6.13-part2
Andi was super busy the last weeks, so this pull requests contains one
series (nomadik) and a number of smaller additions which were ready to
go but nearly overlooked. Despite the late collection, they have been
properly reviewed and have been in -next for 6 days now in Andi's tree.
New feature support:
- Added support for frequencies up to 3.4 MHz on Nomadik I2C.
- DesignWare now accounts for bus capacitance and clock
optimisation (declared as new parameters in the binding) to
improve the calculation of signal rise and fall times
(t_high and t_low).
New Hardware support:
- DWAPB I2C controller on FUJITSU-MONAKA (new ACPI HID).
- Allwinner A523 (new compatible ID).
- Mobileye EyeQ6H (new compatible ID).

Summary
* sysctl ctl_table constification
Constifying ctl_table structs prevents the modification of proc_handler
function pointers. All ctl_table struct arguments are const qualified in the
sysctl API in such a way that the ctl_table arrays being defined elsewhere
and passed through sysctl can be constified one-by-one. We kick the
constification off by qualifying user_table in kernel/ucount.c and expect all
the ctl_tables to be constified in the coming releases.
* Misc fixes
Adjust comments in two places to better reflect the code. Remove superfluous
dput calls. Remove Luis from sysctl maintainership. Replace comments about
holding a lock with calls to lockdep_assert_held.
* Testing
All these went through 0-day and they have all been in linux-next for at
least 1 month (since Oct-24). I also rand these through the sysctl selftest
for x86_64.

MTD device changes: Aside from the platform_driver::remove() switch, two
misc issues got fixed.
SPI-NAND changes:
A load of fixes to Winbond manufacturer driver have been done, plus a
structure constification.
Raw NAND changes:
The GPMI driver has been improved on the power management side.
The Davinci driver has been cleaned up.
A leak in the Atmel driver plus some typos in the core have been fixed.
SPI NOR changes:
Introduce byte swap support for 8D-8D-8D mode and a user for it:
macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary when
configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the
controllers swap the bytes back at runtime. This avoids breaking the
boot sequence because of the endianness problems that appear when the
bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap
support. Along with the SPI MEM byte swap support we queue a patch for
the SPI MXIC controller that swaps the bytes back at runtime.

The core framework gained a clk provider helper, a clk consumer helper, and
some unit tests for the assigned clk rates feature in DeviceTree. On the vendor
driver side, we gained a whole pile of SoC driver support detailed below. The
majority in the diffstat is Qualcomm, but there's also quite a few Samsung and
Mediatek clk driver additions in here as well. The top vendors is quite common,
but the sheer amount of new drivers is uncommon, so I'm anticipating a larger
number of fixes for clk drivers this cycle.
Core:
- devm_clk_bulk_get_all_enabled() to return number of clks acquired
- devm_clk_hw_register_gate_parent_hw() helper to modernize drivers
- KUnit tests for clk-assigned-rates{,-u64}
New Drivers:
- Marvell PXA1908 SoC clks
- Mobileye EyeQ5, EyeQ6L and EyeQ6H clk driver
- TWL6030 clk driver
- Nuvoton Arbel BMC NPCM8XX SoC clks
- MediaTek MT6735 SoC clks
- MediaTek MT7620, MT7628 and MT7688 MMC clks
- Add a driver for gated fixed rate clocks
- Global clock controllers for Qualcomm QCS8300 and IPQ5424 SoCs
- Camera, display and video clock controllers for Qualcomm SA8775P SoCs
- Global, display, GPU, TCSR, and RPMh clock controllers for Qualcomm SAR2130P
- Global, camera, display, GPU, and video clock controllers for Qualcomm
SM8475 SoCs
- RTC power domain and Battery Backup Function (VBATTB) clock support for the
Renesas RZ/G3S SoC
- Qualcomm IPQ9574 alpha PLLs
- Support for i.MX91 CCM in the i.MX93 driver
- Microchip LAN969X SoC clks

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The core framework gained a clk provider helper, a clk consumer
helper, and some unit tests for the assigned clk rates feature in
DeviceTree. On the vendor driver side, we gained a whole pile of SoC
driver support detailed below. The majority in the diffstat is
Qualcomm, but there's also quite a few Samsung and Mediatek clk driver
additions in here as well. The top vendors is quite common, but the
sheer amount of new drivers is uncommon, so I'm anticipating a larger
number of fixes for clk drivers this cycle.
Core:
- devm_clk_bulk_get_all_enabled() to return number of clks acquired
- devm_clk_hw_register_gate_parent_hw() helper to modernize drivers
- KUnit tests for clk-assigned-rates{,-u64}
New Drivers:
- Marvell PXA1908 SoC clks
- Mobileye EyeQ5, EyeQ6L and EyeQ6H clk driver
- TWL6030 clk driver
- Nuvoton Arbel BMC NPCM8XX SoC clks
- MediaTek MT6735 SoC clks

accel/amdxdna: Support hardware mailbox
The hardware mailboxes are used by the driver to submit requests to firmware and receive the completion notices from hardware. Initially, a management mailbox channel is up and running. The driver may request firmware to create/destroy more channels dynamically through management channel. Add driver internal mailbox interfaces. - create/destroy a mailbox channel instance - send a message to the firmware through a specific channel - wait for a notification from the specific channel Co-developed-by: George Yang <George.Yang@amd.com> Signed-off-by: George Yang <George.Yang@amd.com> Co-developed-by: Min Ma <min.ma@amd.com> Signed-off-by: Min Ma <min.ma@amd.com> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Signed-off-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241118172942.2014541-4-lizhi.hou@amd.com |

i2c-for-6.13-rc1
i2c-core (Wolfram)
- drivers can now use a GPIO as a side channel for SMBus Alerts
using a generic binding
- regular stuff like mem leak fix, Makefile maintenance...
i2c-host updates (Andi)
Major Improvements and Refactoring:
- All controllers using the 'remove_new' callback have been
reverted to use the 'remove' callback.
- Intel SCH controller underwent significant refactoring,
this brings love and a modern look to the driver.
- PIIX4 driver refactored to enable usage by other drivers
(e.g., AMD ASF).
- iMX/MXC improved message handling to reduce protocol overhead:
Refactored DMA/non-DMA read/write and bus polling mechanisms
to achieve this.
- ACPI documentation for PIIX4.
New Features:
- i2c-cadence added support for atomic transfers.
- Qualcomm CII added support for a 32MHz serial engine clock.
Deprecated Features:
- Dropped outdated support for AMD756 S4882 and NFORCE2 S4985. If
somebody misses this, Jean will rewrite support using the proper
i2c mux framework.
New Hardware Support:
- Added support for:
- Intel Panther Lake (new ID)
- AMD ASF (new driver)
- S32G2/S32G3 SoCs (new ID)
- Realtek RTL I2C Controller (new driver)

Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase

Merge tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core:
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.

PCI/pwrctrl: Rename pwrctl files to pwrctrl
To slightly reduce confusion between "pwrctl" (the power controller and power sequencing framework) and "bwctrl" (the bandwidth controller), rename "pwrctl" to "pwrctrl" so they use the same "ctrl" suffix. Rename drivers/pci/pwrctl/ to drivers/pci/pwrctrl/, including the related MAINTAINERS, include file (include/linux/pci-pwrctl.h), Makefile, and Kconfig changes. This is the minimal rename of files only. A subsequent commit will rename functions and data structures.

soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending the
set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
and drivers/memory, including changing back the .remove_new callback
to .remove, as well as a few other updates for freescale (powerpc)
soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

gpio updates for v6.13-rc1
GPIOLIB core:
- use the new mem_is_zero() instead of memchr_inv(s, 0, n)
- don't store debounce period twice needlessly
- clean-up debugfs handling
- remove leftover comments referring to no longer used spinlocks
- unduplicate some operations like SRCU locks and initializing GPIO descriptors
- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for consistency with
other places
- modify the behavior of the sysfs interface by no longer exporting lines that
are named inside the driver code or board files with the sysfs links bearing
the line names as this has for many years been largely unused due to the
prevalence of DT, ACPI and firmware nodes over board files and made the API
inconsistent
- for GPIO interrupt providers: free irqs that are still requested by users
when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested, released,
reconfigured) triggered from the kernel as well (until now we'd only do
this for changes triggered from user-space)
- to that end: modify the internal workings of the notification mechanism by
switching to an atomic notifier which allows us to send events from atomic
context
- also to that end store the debounce period in the GPIO descriptor struct
and not in the character device context struct
- while at it, also cover the corner-case of users introducing changes over
sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to user-space as it
can still request them as GPIOs
New drivers:
- add a driver for the GPIO functionality of the MFD Congatec Board Controller
- add a driver for the PolarFire GPIO controller
- add a driver supporting the GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones across
many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci, ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or entirely
remove the driver's remove() callback (grgpio, amdpt, menz127, max730x,
ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid some
line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the fwnode
on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby, xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the conversion to
remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop this
deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in gpiolib-of
and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio
Other:
- kernel doc and comments tweaks
- fix typos in TODO
- reorder headers alphabetically in some drivers
- fix incorrect format specifiers in gpio tools

Pull gpio updates from Bartosz Golaszewski:
"Three new drivers, support for some new models in existing ones and
lots of various tweaks and improvements across the board (switching to
using recommended APIs, code shrink and simplification, etc.).
Also a new feature in the character device uAPI where we now notify
the user-space about changes triggered by in-kernel users as well, not
only when they were done by other user-space agents.

spi: Updates for v6.13
The only real core work we've got this time around is the completion of
the transition to the new host/target naming for the core APIs, Kconfig
still needs doing but that's a lot less invasive. Otherwise the big
changes are the new drivers that have been added:
- Completion of the conversion to spi_alloc_host()/_target() and
removal of the old naming.
- Cleanups for Rockchip drivers, these brought in a new logging helper
in the driver core for warnings during probe.
- Support for configuration of the word delay via spidev_test.
- Support for AMD HID2 controllers, Apple SPI controller and Realtek
SPI-NAND controllers.
The Rockchip cleanups

kgdb patches for 6.13
A relatively modest collection of changes:
* Adopt kstrtoint() and kstrtol() instead of the simple_strtoXX family
for better error checking of user input.
* Align the print behavour when breakpoints are enabled and disabled by
adopting the current behaviour of breakpoint disable for both.
* Remove some of the (rather odd and user hostile) hex fallbacks and
require kdb users to prefix with 0x instead.
* Tidy up (and fix) control code handling in kdb's keyboard code. This
makes the control code handling at the keyboard behave the same way
as it does via the UART.
* Switch my own entry in MAINTAINERS to my @kernel.org address.

A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the signal
of the timer is ignored so that the timer signal can be delivered once
the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small intervals
and keeps the system pointlessly out of low power states for no value.
This is a long standing non-trivial problem due to the lock order of
posix-timer lock and the sighand lock along with life time issues as
the timer and the sigqueue have different life time rules.
Cure this by:
* Embedding the sigqueue into the timer struct to have the same life
time rules. Aside of that this also avoids the lookup of the timer
in the signal delivery and rearm path as it's just a always valid
container_of() now.
* Queuing ignored timer signals onto a seperate ignored list.
* Moving queued timer signals onto the ignored list when the signal is
switched to SIG_IGN before it could be delivered.
* Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal delivery
code to rearm the timer.
This also required to consolidate the signal delivery rules so they are
consistent across all situations. With that all self test scenarios
finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time stamps
by default and switch to fine grained time stamps when inode attributes
are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that the
VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
* Move all sleep and timeout functions into one file
* Rework udelay() and ndelay() into proper documented inline functions
and replace the hardcoded magic numbers by proper defines.
* Rework the fsleep() implementation to take the reality of the timer
wheel granularity on different HZ values into account. Right now the
boundaries are hard coded time ranges which fail to provide the
requested accuracy on different HZ settings.
* Update documentation for all sleep/timeout related functions and fix
up stale documentation links all over the place
* Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as that's
the clock which drives the timekeeping adjustments via the various user
space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file descriptor
based posix clocks, but their usability is very limited. They can't be
accessed fast as they always go all the way out to the hardware and
they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the kernel
provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework converts
timekeeping and adjtimex(2) into generic functionality which operates
on pointers to data structures instead of using static variables.
This allows to provide time accessors and adjtimex(2) functionality for
the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less straight
forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the core
code and a few usage sites of the less frequently used interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is already
prepared and scheduled for the next merge window.
- Drivers:
* Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with other
clusters.
* Mostly boring cleanups, fixes, improvements and code movement

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.

life time rules. Aside of that this also avoids the lookup of
