git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core & protocols: - A significant effort all around the stack to guide the compiler to make the right choice when inlining code, to avoid unneeded calls for small helper and stack canary overhead in the fast-path. This generates better and faster code with very small or no text size increases, as in many cases the call generated more code than the actual inlined helper. - Extend AccECN implementation so that is now functionally complete, also allow the user-space enabling it on a per network namespace basis. - Add support for memory providers with large (above 4K) rx buffer. Paired with hw-gro, larger rx buffer sizes reduce the number of buffers traversing the stack, dincreasing single stream CPU usage by up to ~30%. - Do not add HBH header to Big TCP GSO packets. This simplifies the RX path, the TX path and the NIC drivers, and is possible because user-space taps can now interpret correctly such packets without the HBH hint. - Allow IPv6 routes to be configured with a gateway address that is resolved out of a different interface than the one specified, aligning IPv6 to IPv4 behavior. - Multi-queue aware sch_cake. This makes it possible to scale the rate shaper of sch_cake across multiple CPUs, while still enforcing a single global rate on the interface. - Add support for the nbcon (new buffer console) infrastructure to netconsole, enabling lock-free, priority-based console operations that are safer in crash scenarios. - Improve the TCP ipv6 output path to cache the flow information, saving cpu cycles, reducing cache line misses and stack use. - Improve netfilter packet tracker to resolve clashes for most protocols, avoiding unneeded drops on rare occasions. - Add IP6IP6 tunneling acceleration to the flowtable infrastructure. - Reduce tcp socket size by one cache line. - Notify neighbour changes atomically, avoiding inconsistencies between the notification sequence and the actual states sequence. - Add vsock namespace support, allowing complete isolation of vsocks across different network namespaces. - Improve xsk generic performances with cache-alignment-oriented optimizations. - Support netconsole automatic target recovery, allowing netconsole to reestablish targets when underlying low-level interface comes back online. Driver API: - Support for switching the working mode (automatic vs manual) of a DPLL device via netlink. - Introduce PHY ports representation to expose multiple front-facing media ports over a single MAC. - Introduce "rx-polarity" and "tx-polarity" device tree properties, to generalize polarity inversion requirements for differential signaling. - Add helper to create, prepare and enable managed clocks. Device drivers: - Add Huawei hinic3 PF etherner driver. - Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller. - Add ethernet driver for MaxLinear MxL862xx switches - Remove parallel-port Ethernet driver. - Convert existing driver timestamp configuration reporting to hwtstamp_get and remove legacy ioctl(). - Convert existing drivers to .get_rx_ring_count(), simplifing the RX ring count retrieval. Also remove the legacy fallback path. - Ethernet high-speed NICs: - Broadcom (bnxt, bng): - bnxt: add FW interface update to support FEC stats histogram and NVRAM defragmentation - bng: add TSO and H/W GRO support - nVidia/Mellanox (mlx5): - improve latency of channel restart operations, reducing the used H/W resources - add TSO support for UDP over GRE over VLAN - add flow counters support for hardware steering (HWS) rules - use a static memory area to store headers for H/W GRO, leading to 12% RX tput improvement - Intel (100G, ice, idpf): - ice: reorganizes layout of Tx and Rx rings for cacheline locality and utilizes __cacheline_group* macros on the new layouts - ice: introduces Synchronous Ethernet (SyncE) support - Meta (fbnic): - adds debugfs for firmware mailbox and tx/rx rings vectors - Ethernet virtual: - geneve: introduce GRO/GSO support for double UDP encapsulation - Ethernet NICs consumer, and embedded: - Synopsys (stmmac): - some code refactoring and cleanups - RealTek (r8169): - add support for RTL8127ATF (10G Fiber SFP) - add dash and LTR support - Airoha: - AN8811HB 2.5 Gbps phy support - Freescale (fec): - add XDP zero-copy support - Thunderbolt: - add get link setting support to allow bonding - Renesas: - add support for RZ/G3L GBETH SoC - Ethernet switches: - Maxlinear: - support R(G)MII slow rate configuration - add support for Intel GSW150 - Motorcomm (yt921x): - add DCB/QoS support - TI: - icssm-prueth: support bridging (STP/RSTP) via the switchdev framework - Ethernet PHYs: - Realtek: - enable SGMII and 2500Base-X in-band auto-negotiation - simplify and reunify C22/C45 drivers - Micrel: convert bindings to DT schema - CAN: - move skb headroom content into skb extensions, making CAN metadata access more robust - CAN drivers: - rcar_canfd: - add support for FD-only mode - add support for the RZ/T2H SoC - sja1000: cleanup the CAN state handling - WiFi: - implement EPPKE/802.1X over auth frames support - split up drop reasons better, removing generic RX_DROP - additional FTM capabilities: 6 GHz support, supported number of spatial streams and supported number of LTF repetitions - better mac80211 iterators to enumerate resources - initial UHR (Wi-Fi 8) support for cfg80211/mac80211 - WiFi drivers: - Qualcomm/Atheros: - ath11k: support for Channel Frequency Response measurement - ath12k: a significant driver refactor to support multi-wiphy devices and and pave the way for future device support in the same driver (rather than splitting to ath13k) - ath12k: support for the QCC2072 chipset - Intel: - iwlwifi: partial Neighbor Awareness Networking (NAN) support - iwlwifi: initial support for U-NII-9 and IEEE 802.11bn - RealTek (rtw89): - preparations for RTL8922DE support - Bluetooth: - implement setsockopt(BT_PHY) to set the connection packet type/PHY - set link_policy on incoming ACL connections - Bluetooth drivers: - btusb: add support for MediaTek7920, Realtek RTL8761BU and 8851BE - btqca: add WCN6855 firmware priority selection feature" * tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1254 commits) bnge/bng_re: Add a new HSI net: macb: Fix tx/rx malfunction after phy link down and up af_unix: Fix memleak of newsk in unix_stream_connect(). net: ti: icssg-prueth: Add optional dependency on HSR net: dsa: add basic initial driver for MxL862xx switches net: mdio: add unlocked mdiodev C45 bus accessors net: dsa: add tag format for MxL862xx switches dt-bindings: net: dsa: add MaxLinear MxL862xx selftests: drivers: net: hw: Modify toeplitz.c to poll for packets octeontx2-pf: Unregister devlink on probe failure net: renesas: rswitch: fix forwarding offload statemachine ionic: Rate limit unknown xcvr type messages tcp: inet6_csk_xmit() optimization tcp: populate inet->cork.fl.u.ip6 in tcp_v6_syn_recv_sock() tcp: populate inet->cork.fl.u.ip6 in tcp_v6_connect() ipv6: inet6_csk_xmit() and inet6_csk_update_pmtu() use inet->cork.fl.u.ip6 ipv6: use inet->cork.fl.u.ip6 and np->final in ip6_datagram_dst_update() ipv6: use np->final in inet6_sk_rebuild_header() ipv6: add daddr/final storage in struct ipv6_pinfo net: stmmac: qcom-ethqos: fix qcom_ethqos_serdes_powerup() ...

As there is only one rescuer per workqueue, a single long-blocking work item could cause high latency for all tasks queued behind it, even after memory pressure is relieved and regular kworkers become available to service them. - Add CONFIG_BOOTPARAM_WQ_STALL_PANIC build-time option and workqueue.panic_on_stall_time parameter for time-based stall panic, giving systems more control over workqueue stall handling. - Replace BUG_ON() with panic() in the stall panic path for clearer intent and more informative output. * tag 'wq-for-6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: replace BUG_ON with panic in panic_on_wq_watchdog workqueue: add time-based panic for stalls workqueue: add CONFIG_BOOTPARAM_WQ_STALL_PANIC option workqueue: Process extra works in rescuer on memory pressure workqueue: Process rescuer work items one-by-one using a cursor workqueue: Make send_mayday() take a PWQ argument directly

Pull SoC devicetree updates from Arnd Bergmann: "There are a handful of new SoCs this time, all of these are more or less related to chips in a wider family: - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first widely available RVA23 implementation. Note that this is entirely unrelated with the similarly named Texas Instruments K3 chip family that follwed the TI Keystone2 SoC. - The Realtek Kent family of SoCs contains three chip models rtd1501s, rtd1861b and rtd1920s, and is related to their earlier Set-top-box and NAS products such as rtd1619, but is built on newer Arm Cortex-A78 cores. - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm Cortex-A720 generation. This one is used in the Fairphone Gen 6 - Qualcomm Kaanapali is a new SoC based around eight high performance Oryon CPU cores - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU cores and I/O interfaces. As part of a cleanup, a number of SoC specific devicetree files got removed because they did not have a single board using the .dtsi files and they were never compile tested as a result: Samsung s3c6400, ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/ r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715. All of these could be restored easily if a new board gets merged. Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only machine, as all remaining users are assumed to be using ACPI based firmware. A relatively small number of 43 boards get added this time, and almost all of them for arm64. Aside from the reference boards for the newly added SoCs, this includes: - Three server boards use 32-bit ASpeed BMCs - One more reference board for 32-bit Microchip LAN9668 - 64-bit Arm single-board computers based on Amlogic s905y4, CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020, NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588 - Two mobile phones using Snapdragon 845 - A gaming device and a NAS box, both based on Rockchips rk356x On top of the newly added boards and SoCs, there is a lot of background activity going into cleanups, in particular towards getting a warning-free dtc build, and the usual work on adding support for more hardware on the previously added machines" * tag 'soc-dt-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (757 commits) dt-bindings: intel: Add Agilex eMMC support arm64: dts: socfpga: agilex: add emmc support arm64: dts: intel: agilex5: Add simple-bus node on top of dma controller node ARM: dts: socfpga: fix dtbs_check warning for fpga-region ARM: dts: socfpga: add #address-cells and #size-cells for sram node dt-bindings: altera: document syscon as fallback for sys-mgr arm64: dts: altera: Use lowercase hex dt-bindings: arm: altera: combine Intel's SoCFPGA into altera.yaml arm64: dts: socfpga: agilex5: Add IOMMUS property for ethernet nodes arm64: dts: socfpga: agilex5: add support for modular board dt-bindings: intel: Add Agilex5 SoCFPGA modular board arm64: dts: socfpga: agilex5: Add dma-coherent property arm64: dts: realtek: Add Kent SoC and EVB device trees dt-bindings: arm: realtek: Add Kent Soc family compatibles ARM: dts: samsung: Drop s3c6400.dtsi ARM: dts: nuvoton: Minor whitespace cleanup MAINTAINERS: Add Falcon DB arm64: dts: a7k: add COM Express boards ARM: dts: microchip: Drop usb_a9g20-dab-mmx.dtsi arm64: dts: rockchip: Fix rk3588 PCIe range mappings ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Ingo Molnar: "Lock debugging: - Implement compiler-driven static analysis locking context checking, using the upcoming Clang 22 compiler's context analysis features (Marco Elver) We removed Sparse context analysis support, because prior to removal even a defconfig kernel produced 1,700+ context tracking Sparse warnings, the overwhelming majority of which are false positives. On an allmodconfig kernel the number of false positive context tracking Sparse warnings grows to over 5,200... On the plus side of the balance actual locking bugs found by Sparse context analysis is also rather ... sparse: I found only 3 such commits in the last 3 years. So the rate of false positives and the maintenance overhead is rather high and there appears to be no active policy in place to achieve a zero-warnings baseline to move the annotations & fixers to developers who introduce new code. Clang context analysis is more complete and more aggressive in trying to find bugs, at least in principle. Plus it has a different model to enabling it: it's enabled subsystem by subsystem, which results in zero warnings on all relevant kernel builds (as far as our testing managed to cover it). Which allowed us to enable it by default, similar to other compiler warnings, with the expectation that there are no warnings going forward. This enforces a zero-warnings baseline on clang-22+ builds (Which are still limited in distribution, admittedly) Hopefully the Clang approach can lead to a more maintainable zero-warnings status quo and policy, with more and more subsystems and drivers enabling the feature. Context tracking can be enabled for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default disabled), but this will generate a lot of false positives.

Each CBB and each IMH die has its own discovery domain. - Unlike prior CPUs that retrieve the global discovery table portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON discovery and MSR for CBB PMON discovery. - DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR, PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6. - IIO free-running counters in DMR are MMIO-based, unlike SPR. - Also add support for Add missing PMON units for Intel Panther Lake, and support Nova Lake (NVL), which largely maps to Panther Lake.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "The kthread code provides an infrastructure which manages the preferred affinity of unbound kthreads (node or custom cpumask) against housekeeping (CPU isolation) constraints and CPU hotplug events. One crucial missing piece is the handling of cpuset: when an isolated partition is created, deleted, or its CPUs updated, all the unbound kthreads in the top cpuset become indifferently affine to _all_ the non-isolated CPUs, possibly breaking their preferred affinity along the way. Solve this with performing the kthreads affinity update from cpuset to the kthreads consolidated relevant code instead so that preferred affinities are honoured and applied against the updated cpuset isolated partitions. The dispatch of the new isolated cpumasks to timers, workqueues and kthreads is performed by housekeeping, as per the nice Tejun's suggestion. As a welcome side effect, HK_TYPE_DOMAIN then integrates both the set from boot defined domain isolation (through isolcpus=) and cpuset isolated partitions. Housekeeping cpumasks are now modifiable with a specific RCU based synchronization.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "By the number of commits, cpufreq is the leading party (again) and the most visible change there is the removal of the omap-cpufreq driver that has not been used for a long time (good riddance). There are also quite a few changes in the cppc_cpufreq driver, mostly related to fixing its frequency invariance engine in the case when the CPPC registers used by it are not in PCC. In addition to that, support for AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev list is updated for some platforms. The remaining cpufreq changes are assorted fixes and cleanups. Next up is cpuidle and the changes there are dominated by intel_idle driver updates, mostly related to the new command line facility allowing users to adjust the list of C-states used by the driver. There are also a few updates of cpuidle governors, including two menu governor fixes and some refinements of the teo governor, and a MAINTAINERS update adding Christian Loehle as a cpuidle reviewer. [Thanks for stepping up Christian!] The most significant update related to system suspend and hibernation is the one to stop freezing the PM runtime workqueue during system PM transitions which allows some deadlocks to be avoided. There is also a fix for possible concurrent bit field updates in the core device suspend code and a few other minor fixes. Apart from the above, several drivers are updated to discard the return value of pm_runtime_put() which is going to be converted to a void function as soon as everybody stops using its return value, PL4 support for Ice Lake is added to the Intel RAPL power capping driver, and there are assorted cleanups, documentation fixes, and some cpupower utility improvements.

Make the menu cpuidle governor always check the time till the closest timer event when the scheduler tick has been stopped to prevent it from mistakenly selecting the deepest available idle state (Rafael Wysocki) - Update the teo cpuidle governor to avoid making suboptimal decisions in certain corner cases and generally improve idle state selection accuracy (Rafael Wysocki) - Remove an unlikely() annotation on the early-return condition in menu_select() that leads to branch misprediction 100% of the time on systems with only 1 idle state enabled, like ARM64 servers (Breno Leitao) -

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "This one is significantly larger than previous ACPI support pull requests because several significant updates have coincided in it. First, there is a routine ACPICA code update, to upstream version 20251212, but this time it covers new ACPI 6.6 material that has not been covered yet. Among other things, it includes definitions of a few new ACPI tables and updates of some others, like the GICv5 MADT structures and ARM IORT IWB node definitions that are used for adding GICv5 ACPI probing on ARM (that technically is IRQ subsystem material, but it depends on the ACPICA changes, so it is included here). The latter alone adds a few hundred lines of new code. Second, there is an update of ACPI _OSC handling including a fix that prevents failures from occurring in some corner cases due to careless handling of _OSC error bits. On top of that, the "system resource" ACPI device objects with the PNP0C01 and PNP0C02 are now going to be handled by the ACPI core device enumeration code instead of handing them over to the legacy PNP system driver which causes device enumeration issues to occur. Some of those issues have been worked around in device drivers and elsewhere and those workarounds should not be necessary any more, so they are going away. Moreover, the time has come to convert all "core ACPI" device drivers that were still using struct acpi_driver objects for device binding into proper platform drivers that use struct platform_driver for this purpose. These updates are accompanied by some requisite core ACPI device enumeration code changes. Next, there are ACPI APEI updates, including changes to avoid excess overhead in the NMI handler and in SEA on the ARM side, changes to unify ACPI-based HW error tracing and logging, and changes to prevent APEI code from reaching out of its allocated memory. There are also some ACPI power management updates, mostly related to the ACPI cpuidle support in the processor driver, suspend-to-idle handling on systems with ACPI support and to ACPI PM of devices. In addition to the above, bugs are fixed and the code is cleaned up in assorted places all over. Specifics: - Update the ACPICA code in the kernel to upstream version 20251212 which includes the following changes: * Add support for new ACPI table DTPR (Michal Camacho Romero) * Release objects with acpi_ut_delete_object_desc() (Zilin Guan) * Add UUIDs for Microsoft fan extensions and UUIDs associated with TPM 2.0 devices (Armin Wolf) * Fix NULL pointer dereference in acpi_ev_address_space_dispatch() (Alexey Simakov) * Add KEYP ACPI table definition (Dave Jiang) * Add support for the Microsoft display mux _OSI string (Armin Wolf) * Add definitions for the IOVT ACPI table (Xianglai Li) * Abort AML bytecode execution on AML_FATAL_OP (Armin Wolf) * Include all fields in subtable type1 for PPTT (Ben Horgan) * Add GICv5 MADT structures and Arm IORT IWB node definitions (Jose Marinho) * Update Parameter Block structure for RAS2 and add a new flag in Memory Affinity Structure for SRAT (Pawel Chmielewski) * Add _VDM (Voltage Domain) object (Pawel Chmielewski) - Add support for GICv5 ACPI probing on ARM which is based on the GICv5 MADT structures and ARM IORT IWB node definitions recently added to ACPICA (Lorenzo Pieralisi) - Rework ACPI PM notification setup for PCI root buses and modify the ACPI PM setup for devices to register wakeup source objects under physical (that is, PCI, platform, etc.) devices instead of doing that under their ACPI companions (Rafael Wysocki) - Adjust debug messages regarding postponed ACPI PM printed during system resume to be more accurate (Rafael Wysocki) - Remove dead code from lps0_device_attach() (Gergo Koteles) - Start to invoke Microsoft Function 9 (Turn On Display) of the Low- Power S0 Idle (LPS0) _DSM in the suspend-to-idle resume flow on systems with ACPI LPS0 support to address a functional issue on Lenovo Yoga Slim 7i Aura (15ILL9), where system fans and keyboard backlights fail to resume after suspend (Jakob Riemenschneider) - Add sysfs attribute cid for exposing _CID lists under ACPI device objects (Rafael Wysocki) - Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs interface code (Sumeet Pawnikar) - Use acpi_get_local_u64_address() in the code implementing ACPI support for PCI to evaluate _ADR instead of evaluating that object directly (Andy Shevchenko) - Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak serial IRQs on that system (Ai Chao) - Fix handling of _OSC errors in acpi_run_osc() to avoid failures on systems where _OSC error bits are set even though the _OSC return buffer contains acknowledged feature bits (Rafael Wysocki) - Clean up and rearrange \_SB._OSC handling for general platform features and USB4 features to avoid code duplication and unnecessary memory management overhead (Rafael Wysocki) - Make the ACPI core device enumeration code handle PNP0C01 and PNP0C02 ("system resource") device objects directly instead of letting the legacy PNP system driver handle them to avoid device enumeration issues on systems where PNP0C02 is present in the _CID list under ACPI device objects with a _HID matching a proper device driver in Linux (Rafael Wysocki) -
