For me the CIX Semi and Axis\n Communications ARTPEC-9 SoCs were the most interesting new drivers in\n this merge window.\n\n Core changes:\n\n - Handle per-direction skew control in the generic pin config\n\n - Drop the pointless subsystem boilerplate banner message during\n boot. Less noise in the console. It\u0027s available as debug message if\n someone really want it\n\n New drivers:\n\n - Samsung Exynos 8890 SoC support\n\n - Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.\n These guys literally live next door to me, ARTPEC spells out \"Axis\n Real-Time Picture Encoding Chip\" and is tailored for camera image\n streams and is something they have evolved for a quarter of a\n century\n\n - Mediatek MT6878 SoC support\n\n - Qualcomm Glymur PMIC support (mostly just compatible strings)\n\n - Qualcomm Kaanapali SoC TLMM support\n\n - Microchip pic64gx \"gpio2\" SoC support\n\n - Microchip Polarfire \"iomux0\" SoC support\n\n - CIX Semiconductors SKY1 SoC support\n\n - Rockchip RK3506 SoC support\n\n - Airhoa AN7583 chip support\n\n Improvements:\n\n - Improvements for ST Microelectronics STM32 handling of skew\n settings so input and output can have different skew settings\n\n -

This capability is critical for cloud\n environments, allowing hypervisors to be updated with minimal\n downtime for running virtual machines. LUO achieves this by\n preserving the state of selected resources, such as memory,\n devices and their dependencies, across the kernel transition.\n\n As a key feature, this series includes support for preserving\n memfd file descriptors, which allows critical in-memory data, such\n as guest RAM or any other large memory region, to be maintained in\n RAM across the kexec reboot.\n\n Mike Rappaport merits a mention here, for his extensive review and\n testing work.\n\n - \"kexec: reorganize kexec and kdump sysfs\" (Sourabh Jain)\n moves the kexec and kdump sysfs entries from /sys/kernel/ to\n /sys/kernel/kexec/ and adds back-compatibility symlinks which can\n hopefully be removed one day\n\n - \"kho: fixes for vmalloc restoration\" (Mike Rapoport)\n fixes a BUG which was being hit during KHO restoration of vmalloc()\n regions\n\n* tag \u0027mm-nonmm-stable-2025-12-06-11-14\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (139 commits)\n calibrate: update header inclusion\n Reinstate \"resource: avoid unnecessary lookups in find_next_iomem_res()\"\n vmcoreinfo: track and log recoverable hardware errors\n kho: fix restoring of contiguous ranges of order-0 pages\n kho: kho_restore_vmalloc: fix initialization of pages array\n MAINTAINERS: TPM DEVICE DRIVER: update the W-tag\n init: replace simple_strtoul with kstrtoul to improve lpj_setup\n KHO: fix boot failure due to kmemleak access to non-PRESENT pages\n Documentation/ABI: new kexec and kdump sysfs interface\n Documentation/ABI: mark old kexec sysfs deprecated\n kexec: move sysfs entries to /sys/kernel/kexec\n test_kho: always print restore status\n kho: free chunks using free_page() instead of kfree()\n selftests/liveupdate: add kexec test for multiple and empty sessions\n selftests/liveupdate: add simple kexec-based selftest for LUO\n selftests/liveupdate: add userspace API selftests\n docs: add documentation for memfd preservation via LUO\n mm: memfd_luo: allow preserving memfd\n liveupdate: luo_file: add private argument to store runtime state\n mm: shmem: export some functions to internal.h\n ...\n" }, { "commit": "09670b8c38b37bc2d6fc5d01fa7e02c38f7adf36", "tree": "3b1a816d8f2056ece2881b52fbc4bb717d1b1554", "parents": [ "cc3ee4ba57b76deefb52aee5f57a46dc07bda9f7", "c5108c58b991cb6cac78947ac3811321895190e2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 06 13:49:40 2025 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 06 13:49:40 2025 -0800" }, "message": "Merge tag \u0027trace-v6.19-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace\n\nPull tracing fixes from Steven Rostedt:\n\n - Fix accounting of stop_count in file release\n\n On opening the trace file, if \"pause-on-trace\" option is set, it will\n increment the stop_count.

The PCI core changes have an ack from Bjorn, the crypto/ccp/\n changes have an ack from Tom, and the iommu/amd/ changes have an ack\n from Joerg.\n\n PCIe link encryption is made possible by the soup of acronyms\n mentioned in the shortlog below. Link Integrity and Data Encryption\n (IDE) is a protocol for installing keys in the transmitter and\n receiver at each end of a link. That protocol is transported over Data\n Object Exchange (DOE) mailboxes using PCI configuration requests.\n\n The aspect that makes this a \"platform firmware service\" is that the\n key provisioning and protocol is coordinated through a Trusted\n Execution Envrionment (TEE) Security Manager (TSM). That is either\n firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor\n software (Intel TDX Connect / ARM CCA) running in a protected CPU\n mode.\n\n Now, the only reason to ask a TSM to run this protocol and install the\n keys rather than have a Linux driver do the same is so that later, a\n confidential VM can ask the TSM directly \"can you certify this\n device?\".\n\n That precludes host Linux from provisioning its own keys, because host\n Linux is outside the trust domain for the VM. It also turns out that\n all architectures, save for one, do not publish a mechanism for an OS\n to establish keys in the root port. So \"TSM-established link\n encryption\" is the only cross-architecture path for this capability\n for the foreseeable future.\n\n This unblocks the other arch implementations to follow in v6.20/v7.0,\n once they clear some other dependencies, and it unblocks the next\n phase of work to implement the end-to-end flow of confidential device\n assignment. The PCIe specification calls this end-to-end flow Trusted\n Execution Environment (TEE) Device Interface Security Protocol\n (TDISP).\n\n In the meantime, Linux gets a link encryption facility which has\n practical benefits along the same lines as memory encryption. It\n authenticates devices via certificates and may protect against\n interposer attacks trying to capture clear-text PCIe traffic.\n\n Summary:\n\n - Introduce the PCI/TSM core for the coordination of device\n authentication, link encryption and establishment (IDE), and later\n management of the device security operational states (TDISP).\n Notify the new TSM core layer of PCI device arrival and departure\n\n - Add a low level TSM driver for the link encryption establishment\n capabilities of the AMD SEV-TIO architecture\n\n - Add a library of helpers TSM drivers to use for IDE establishment\n and the DOE transport\n\n - Add skeleton support for \u0027bind\u0027 and \u0027guest_request\u0027 operations in\n support of TDISP\"\n\n* tag \u0027tsm-for-6.19\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm: (23 commits)\n crypto/ccp: Fix CONFIG_PCI\u003dn build\n virt: Fix Kconfig warning when selecting TSM without VIRT_DRIVERS\n crypto/ccp: Implement SEV-TIO PCIe IDE (phase1)\n iommu/amd: Report SEV-TIO support\n psp-sev: Assign numbers to all status codes and add new\n ccp: Make snp_reclaim_pages and __sev_do_cmd_locked public\n PCI/TSM: Add \u0027dsm\u0027 and \u0027bound\u0027 attributes for dependent functions\n PCI/TSM: Add pci_tsm_guest_req() for managing TDIs\n PCI/TSM: Add pci_tsm_bind() helper for instantiating TDIs\n PCI/IDE: Initialize an ID for all IDE streams\n PCI/IDE: Add Address Association Register setup for downstream MMIO\n resource: Introduce resource_assigned() for discerning active resources\n PCI/TSM: Drop stub for pci_tsm_doe_transfer()\n drivers/virt: Drop VIRT_DRIVERS build dependency\n PCI/TSM: Report active IDE streams\n PCI/IDE: Report available IDE streams\n PCI/IDE: Add IDE establishment helpers\n PCI: Establish document for PCI host bridge sysfs attributes\n PCI: Add PCIe Device 3 Extended Capability enumeration\n PCI/TSM: Establish Secure Sessions and Link Encryption\n ...\n" }, { "commit": "fbff94967958e46f7404b2dfbcf3b19e96aaaae2", "tree": "86d19e02807120c3b37f31495d9572e85ebd162f", "parents": [ "973ec55764d0f0e25d495392477056d6a0be4660", "5bcc5786a0cfa9249ccbe539833040a6285d0de3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 06 10:00:49 2025 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 06 10:00:49 2025 -0800" }, "message": "Merge tag \u0027linux-watchdog-6.19-rc1\u0027 of git://www.linux-watchdog.org/linux-watchdog\n\nPull watchdog updates from Wim Van Sebroeck:\n\n -

Bonzini:\n \"ARM:\n\n - Support for userspace handling of synchronous external aborts\n (SEAs), allowing the VMM to potentially handle the abort in a\n non-fatal manner\n\n - Large rework of the VGIC\u0027s list register handling with the goal of\n supporting more active/pending IRQs than available list registers\n in hardware. In addition, the VGIC now supports EOImode\u003d\u003d1 style\n deactivations for IRQs which may occur on a separate vCPU than the\n one that acked the IRQ\n\n - Support for FEAT_XNX (user / privileged execute permissions) and\n FEAT_HAF (hardware update to the Access Flag) in the software page\n table walkers and shadow MMU\n\n - Allow page table destruction to reschedule, fixing long\n need_resched latencies observed when destroying a large VM\n\n - Minor fixes to KVM and selftests\n\n Loongarch:\n\n - Get VM PMU capability from HW GCFG register\n\n - Add AVEC basic support\n\n - Use 64-bit register definition for EIOINTC\n\n - Add KVM timer test cases for tools/selftests\n\n RISC/V:\n\n - SBI message passing (MPXY) support for KVM guest\n\n - Give a new, more specific error subcode for the case when in-kernel\n AIA virtualization fails to allocate IMSIC VS-file\n\n - Support KVM_DIRTY_LOG_INITIALLY_SET, enabling dirty log gradually\n in small chunks\n\n - Fix guest page fault within HLV* instructions\n\n - Flush VS-stage TLB after VCPU migration for Andes cores\n\n s390:\n\n - Always allocate ESCA (Extended System Control Area), instead of\n starting with the basic SCA and converting to ESCA with the\n addition of the 65th vCPU. The price is increased number of exits\n (and worse performance) on z10 and earlier processor; ESCA was\n introduced by z114/z196 in 2010\n\n - VIRT_XFER_TO_GUEST_WORK support\n\n - Operation exception forwarding support\n\n - Cleanups\n\n x86:\n\n - Skip the costly \"zap all SPTEs\" on an MMIO generation wrap if MMIO\n SPTE caching is disabled, as there can\u0027t be any relevant SPTEs to\n zap\n\n - Relocate a misplaced export\n\n - Fix an async #PF bug where KVM would clear the completion queue\n when the guest transitioned in and out of paging mode, e.g. when\n handling an SMI and then returning to paged mode via RSM\n\n - Leave KVM\u0027s user-return notifier registered even when disabling\n virtualization, as long as kvm.ko is loaded. On reboot/shutdown,\n keeping the notifier registered is ok; the kernel does not use the\n MSRs and the callback will run cleanly and restore host MSRs if the\n CPU manages to return to userspace before the system goes down\n\n - Use the checked version of {get,put}_user()\n\n - Fix a long-lurking bug where KVM\u0027s lack of catch-up logic for\n periodic APIC timers can result in a hard lockup in the host\n\n - Revert the periodic kvmclock sync logic now that KVM doesn\u0027t use a\n clocksource that\u0027s subject to NTP corrections\n\n - Clean up KVM\u0027s handling of MMIO Stale Data and L1TF, and bury the\n latter behind CONFIG_CPU_MITIGATIONS\n\n - Context switch XCR0, XSS, and PKRU outside of the entry/exit fast\n path; the only reason they were handled in the fast path was to\n paper of a bug in the core #MC code, and that has long since been\n fixed\n\n - Add emulator support for AVX MOV instructions, to play nice with\n emulated devices whose guest drivers like to access PCI BARs with\n large multi-byte instructions\n\n x86 (AMD):\n\n - Fix a few missing \"VMCB dirty\" bugs\n\n - Fix the worst of KVM\u0027s lack of EFER.LMSLE emulation\n\n - Add AVIC support for addressing 4k vCPUs in x2AVIC mode\n\n - Fix incorrect handling of selective CR0 writes when checking\n intercepts during emulation of L2 instructions\n\n - Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]\n on VMRUN and #VMEXIT\n\n - Fix a bug where KVM corrupt the guest code stream when re-injecting\n a soft interrupt if the guest patched the underlying code after the\n VM-Exit, e.g. when Linux patches code with a temporary INT3\n\n - Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits\n to userspace, and extend KVM \"support\" to all policy bits that\n don\u0027t require any actual support from KVM\n\n x86 (Intel):\n\n - Use the root role from kvm_mmu_page to construct EPTPs instead of\n the current vCPU state, partly as worthwhile cleanup, but mostly to\n pave the way for tracking per-root TLB flushes, and elide EPT\n flushes on pCPU migration if the root is clean from a previous\n flush\n\n - Add a few missing nested consistency checks\n\n - Rip out support for doing \"early\" consistency checks via hardware\n as the functionality hasn\u0027t been used in years and is no longer\n useful in general; replace it with an off-by-default module param\n to WARN if hardware fails a check that KVM does not perform\n\n - Fix a currently-benign bug where KVM would drop the guest\u0027s\n SPEC_CTRL[63:32] on VM-Enter\n\n - Misc cleanups\n\n - Overhaul the TDX code to address systemic races where KVM (acting\n on behalf of userspace) could inadvertantly trigger lock contention\n in the TDX-Module; KVM was either working around these in weird,\n ugly ways, or was simply oblivious to them (though even Yan\u0027s\n devilish selftests could only break individual VMs, not the host\n kernel)\n\n - Fix a bug where KVM could corrupt a vCPU\u0027s cpu_list when freeing a\n TDX vCPU, if creating said vCPU failed partway through\n\n - Fix a few sparse warnings (bad annotation, 0 !\u003d NULL)\n\n - Use struct_size() to simplify copying TDX capabilities to userspace\n\n - Fix a bug where TDX would effectively corrupt user-return MSR\n values if the TDX Module rejects VP.ENTER and thus doesn\u0027t clobber\n host MSRs as expected\n\n Selftests:\n\n - Fix a math goof in mmu_stress_test when running on a single-CPU\n system/VM\n\n - Forcefully override ARCH from x86_64 to x86 to play nice with\n specifying ARCH\u003dx86_64 on the command line\n\n - Extend a bunch of nested VMX to validate nested SVM as well\n\n - Add support for LA57 in the core VM_MODE_xxx macro, and add a test\n to verify KVM can save/restore nested VMX state when L1 is using\n 5-level paging, but L2 is not\n\n - Clean up the guest paging code in anticipation of sharing the core\n logic for nested EPT and nested NPT\n\n guest_memfd:\n\n - Add NUMA mempolicy support for guest_memfd, and clean up a variety\n of rough edges in guest_memfd along the way\n\n - Define a CLASS to automatically handle get+put when grabbing a\n guest_memfd from a memslot to make it harder to leak references\n\n - Enhance KVM selftests to make it easer to develop and debug\n selftests like those added for guest_memfd NUMA support, e.g. where\n test and/or KVM bugs often result in hard-to-debug SIGBUS errors\n\n - Misc cleanups\n\n Generic:\n\n - Use the recently-added WQ_PERCPU when creating the per-CPU\n workqueue for irqfd cleanup\n\n - Fix a goof in the dirty ring documentation\n\n - Fix choice of target for directed yield across different calls to\n kvm_vcpu_on_spin(); the function was always starting from the first\n vCPU instead of continuing the round-robin search\"\n\n* tag \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/virt/kvm/kvm: (260 commits)\n KVM: arm64: at: Update AF on software walk only if VM has FEAT_HAFDBS\n KVM: arm64: at: Use correct HA bit in TCR_EL2 when regime is EL2\n KVM: arm64: Document KVM_PGTABLE_PROT_{UX,PX}\n KVM: arm64: Fix spelling mistake \"Unexpeced\" -\u003e \"Unexpected\"\n KVM: arm64: Add break to default case in kvm_pgtable_stage2_pte_prot()\n KVM: arm64: Add endian casting to kvm_swap_s[12]_desc()\n KVM: arm64: Fix compilation when CONFIG_ARM64_USE_LSE_ATOMICS\u003dn\n KVM: arm64: selftests: Add test for AT emulation\n KVM: arm64: nv: Expose hardware access flag management to NV guests\n KVM: arm64: nv: Implement HW access flag management in stage-2 SW PTW\n KVM: arm64: Implement HW access flag management in stage-1 SW PTW\n KVM: arm64: Propagate PTW errors up to AT emulation\n KVM: arm64: Add helper for swapping guest descriptor\n KVM: arm64: nv: Use pgtable definitions in stage-2 walk\n KVM: arm64: Handle endianness in read helper for emulated PTW\n KVM: arm64: nv: Stop passing vCPU through void ptr in S2 PTW\n KVM: arm64: Call helper for reading descriptors directly\n KVM: arm64: nv: Advertise support for FEAT_XNX\n KVM: arm64: Teach ptdump about FEAT_XNX permissions\n KVM: s390: Use generic VIRT_XFER_TO_GUEST_WORK functions\n ...\n" }, { "commit": "399ead3a6d76cbdd29a716660db5c84a314dab70", "tree": "21fabb627af50846eebd0aed52da7d65953b6221", "parents": [ "07025b51c1149951d64804c73014499bb3564dca", "a3209bb94b36351f11e0d9e72ac44e5dd777a069" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Dec 05 16:30:56 2025 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Dec 05 16:30:56 2025 -0800" }, "message": "Merge tag \u0027uml-for-linux-6.19-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/uml/linux\n\nPull UML updates from Johannes Berg:\n \"Apart from the usual small churn, we have\n\n -

A reference is grabbed and not released, but it\u0027s not actually\n _stored_ anywhere.\n\n That works, but it\u0027s hard to follow and verify; among other things, we\n have no way to tell _which_ of the increments is intended to be an\n unpaired one. Worse, on removal we need to decide whether the\n reference had already been dropped, which can be non-trivial if that\n removal is on umount and we need to figure out if this dentry is\n pinned due to e.g. unlink() not done. Usually that is handled by using\n kill_litter_super() as -\u003ekill_sb(), but there are open-coded special\n cases of the same (consider e.g. /proc/self).\n\n Things get simpler if we introduce a new dentry flag\n (DCACHE_PERSISTENT) marking those \"leaked\" dentries. Having it set\n claims responsibility for +1 in refcount.\n\n The end result this series is aiming for:\n\n - get these unbalanced dget() and dput() replaced with new primitives\n that would, in addition to adjusting refcount, set and clear\n persistency flag.\n\n - instead of having kill_litter_super() mess with removing the\n remaining \"leaked\" references (e.g. for all tmpfs files that hadn\u0027t\n been removed prior to umount), have the regular\n shrink_dcache_for_umount() strip DCACHE_PERSISTENT of all dentries,\n dropping the corresponding reference if it had been set. After that\n kill_litter_super() becomes an equivalent of kill_anon_super().\n\n Doing that in a single step is not feasible - it would affect too many\n places in too many filesystems. It has to be split into a series.\n\n This work has really started early in 2024; quite a few preliminary\n pieces have already gone into mainline.

This reduce memory allocation/free of temporary\n working memory\n - Cleanup code using __free()\n - Replace strcpy() with memcpy() in __trace_probe_log_err()\"\n\n* tag \u0027probes-v6.19\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:\n tracing: fprobe: use ftrace if CONFIG_DYNAMIC_FTRACE_WITH_ARGS\n lib/test_fprobe: add testcase for mixed fprobe\n tracing: fprobe: optimization for entry only case\n tracing: fprobe: Fix to init fprobe_ip_table earlier\n tracing: fprobe: Remove unused local variable\n tracing: probes: Replace strcpy() with memcpy() in __trace_probe_log_err()\n tracing: fprobe: fix suspicious rcu usage in fprobe_entry\n tracing: uprobe: eprobes: Allocate traceprobe_parse_context per probe\n tracing: uprobes: Cleanup __trace_uprobe_create() with __free()\n tracing: eprobe: Cleanup eprobe event using __free()\n tracing: probes: Use __free() for trace_probe_log\n tracing: fprobe: use rhltable for fprobe_ip_table\n" }, { "commit": "2e8c1c6a5043999d867d0dcf38be96903c99601a", "tree": "77e2beba634b1bb62e11d6262ddc9352f2d3946c", "parents": [ "2ba59045fba395c076a4880012583fdac25c6d7f", "d3042cbe84a060b4df764eb6c5300bbe20d125ca" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Dec 05 10:53:43 2025 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Dec 05 10:53:43 2025 -0800" }, "message": "Merge tag \u0027ktest-v6.19\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest\n\nPull ktest fix from Steven Rostedt:\n\n - Fix incorrect variable in error message in config-bisect.pl\n\n If the old config file fails to get copied as the last good or bad\n config file, then it fails the program and prints an error message.\n\n But the variable used to print what the old config\u0027s name was\n incorrect.
