Théo Lebrun	54202106c0	dt-bindings: i2c: nomadik: support 400kHz < clock-frequency <= 3.4MHz ... Hardware is not limited to 400kHz, its documentation does mention how to configure it for high-speed (a specific Speed-Mode enum value and a different bus rate clock divider register to be used).

Linus Torvalds	9f16d5e6f2	The biggest change here is eliminating the awful idea that KVM had, of ... essentially guessing which pfns are refcounted pages. The reason to do so was that KVM needs to map both non-refcounted pages (for example BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP VMAs that contain refcounted pages. However, the result was security issues in the past, and more recently the inability to map VM_IO and VM_PFNMAP memory that _is_ backed by struct page but is not refcounted. In particular this broke virtio-gpu blob resources (which directly map host graphics buffers into the guest as "vram" for the virtio-gpu device) with the amdgpu driver, because amdgpu allocates non-compound higher order pages and the tail pages could not be mapped into KVM. This requires adjusting all uses of struct page in the per-architecture code, to always work on the pfn whenever possible. The large series that did this, from David Stevens and Sean Christopherson, also cleaned up substantially the set of functions that provided arch code with the pfn for a host virtual addresses. The previous maze of twisty little passages, all different, is replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the non-__ versions of these two, and kvm_prefetch_pages) saving almost 200 lines of code. ARM: * Support for stage-1 permission indirection (FEAT_S1PIE) and permission overlays (FEAT_S1POE), including nested virt + the emulated page table walker * Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call was introduced in PSCIv1.3 as a mechanism to request hibernation, similar to the S4 state in ACPI * Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As part of it, introduce trivial initialization of the host's MPAM context so KVM can use the corresponding traps * PMU support under nested virtualization, honoring the guest hypervisor's trap configuration and event filtering when running a nested guest * Fixes to vgic ITS serialization where stale device/interrupt table entries are not zeroed when the mapping is invalidated by the VM * Avoid emulated MMIO completion if userspace has requested synchronous external abort injection * Various fixes and cleanups affecting pKVM, vCPU initialization, and selftests LoongArch: * Add iocsr and mmio bus simulation in kernel. * Add in-kernel interrupt controller emulation. * Add support for virtualization extensions to the eiointc irqchip. PPC: * Drop lingering and utterly obsolete references to PPC970 KVM, which was removed 10 years ago. * Fix incorrect documentation references to non-existing ioctls RISC-V: * Accelerate KVM RISC-V when running as a guest * Perf support to collect KVM guest statistics from host side s390: * New selftests: more ucontrol selftests and CPU model sanity checks * Support for the gen17 CPU model * List registers supported by KVM_GET/SET_ONE_REG in the documentation x86: * Cleanup KVM's handling of Accessed and Dirty bits to dedup code, improve documentation, harden against unexpected changes. Even if the hardware A/D tracking is disabled, it is possible to use the hardware-defined A/D bits to track if a PFN is Accessed and/or Dirty, and that removes a lot of special cases. * Elide TLB flushes when aging secondary PTEs, as has been done in x86's primary MMU for over 10 years. * Recover huge pages in-place in the TDP MMU when dirty page logging is toggled off, instead of zapping them and waiting until the page is re-accessed to create a huge mapping. This reduces vCPU jitter. * Batch TLB flushes when dirty page logging is toggled off. This reduces the time it takes to disable dirty logging by ~3x. * Remove the shrinker that was (poorly) attempting to reclaim shadow page tables in low-memory situations. * Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE. * Advertise CPUIDs for new instructions in Clearwater Forest * Quirk KVM's misguided behavior of initialized certain feature MSRs to their maximum supported feature set, which can result in KVM creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero value results in the vCPU having invalid state if userspace hides PDCM from the guest, which in turn can lead to save/restore failures. * Fix KVM's handling of non-canonical checks for vCPUs that support LA57 to better follow the "architecture", in quotes because the actual behavior is poorly documented. E.g. most MSR writes and descriptor table loads ignore CR4.LA57 and operate purely on whether the CPU supports LA57. * Bypass the register cache when querying CPL from kvm_sched_out(), as filling the cache from IRQ context is generally unsafe; harden the cache accessors to try to prevent similar issues from occuring in the future. The issue that triggered this change was already fixed in 6.12, but was still kinda latent. * Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM over-advertises SPEC_CTRL when trying to support cross-vendor VMs. * Minor cleanups * Switch hugepage recovery thread to use vhost_task. These kthreads can consume significant amounts of CPU time on behalf of a VM or in response to how the VM behaves (for example how it accesses its memory); therefore KVM tried to place the thread in the VM's cgroups and charge the CPU time consumed by that work to the VM's container. However the kthreads did not process SIGSTOP/SIGCONT, and therefore cgroups which had KVM instances inside could not complete freezing. Fix this by replacing the kthread with a PF_USER_WORKER thread, via the vhost_task abstraction. Another 100+ lines removed, with generally better behavior too like having these threads properly parented in the process tree. * Revert a workaround for an old CPU erratum (Nehalem/Westmere) that didn't really work; there was really nothing to work around anyway: the broken patch was meant to fix nested virtualization, but the PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the erratum. * Fix 6.12 regression where CONFIG_KVM will be built as a module even if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is 'y'. x86 selftests: * x86 selftests can now use AVX. Documentation: * Use rST internal links * Reorganize the introduction to the API document Generic: * Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock instead of RCU, so that running a vCPU on a different task doesn't encounter long due to having to wait for all CPUs become quiescent. In general both reads and writes are rare, but userspace that supports confidential computing is introducing the use of "helper" vCPUs that may jump from one host processor to another. Those will be very happy to trigger a synchronize_rcu(), and the effect on performance is quite the disaster. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmc9MRYUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroP00QgArxqxBIGLCW5t7bw7vtNq63QYRyh4 dTiDguLiYQJ+AXmnRu11R6aPC7HgMAvlFCCmH+GEce4WEgt26hxCmncJr/aJOSwS letCS7TrME16PeZvh25A1nhPBUw6mTF1qqzgcdHMrqXG8LuHoGcKYGSRVbkf3kfI 1ZoMq1r8ChXbVVmCx9DQ3gw1TVr5Dpjs2voLh8rDSE9Xpw0tVVabHu3/NhQEz/F+ t8/nRaqH777icCHIf9PCk5HnarHxLAOvhM2M0Yj09PuBcE5fFQxpxltw/qiKQqqW ep4oquojGl87kZnhlDaac2UNtK90Ws+WxxvCwUmbvGN0ZJVaQwf4FvTwig== =lWpE -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The biggest change here is eliminating the awful idea that KVM had of essentially guessing which pfns are refcounted pages.

Improved efficiencies for userspace memory allocators are expected. - The series "memcg: tracepoint for flushing stats" from JP Kobryn uses tracepoints to provide increased visibility into memcg stats flushing activity. - The series "zram: IDLE flag handling fixes" from Sergey Senozhatsky fixes a zram buglet which potentially affected performance. - The series "mm: add more kernel parameters to control mTHP" from Maíra Canal enhances our ability to control/configuremultisize THP from the kernel boot command line. - The series "kasan: few improvements on kunit tests" from Sabyrzhan Tasbolatov has a couple of fixups for the KASAN KUnit tests. - The series "mm/list_lru: Split list_lru lock into per-cgroup scope" from Kairui Song optimizes list_lru memory utilization when lockdep is enabled. * tag 'mm-stable-2024-11-18-19-27' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (215 commits) cma: enforce non-zero pageblock_order during cma_init_reserved_mem() mm/kfence: add a new kunit test test_use_after_free_read_nofault() zram: fix NULL pointer in comp_algorithm_show() memcg/hugetlb: add hugeTLB counters to memcg vmstat: call fold_vm_zone_numa_events() before show per zone NUMA event mm: mmap_lock: check trace_mmap_lock_$type_enabled() instead of regcount zram: ZRAM_DEF_COMP should depend on ZRAM MAINTAINERS/MEMORY MANAGEMENT: add document files for mm Docs/mm/damon: recommend academic papers to read and/or cite mm: define general function pXd_init() kmemleak: iommu/iova: fix transient kmemleak false positive mm/list_lru: simplify the list_lru walk callback function mm/list_lru: split the lock to per-cgroup scope mm/list_lru: simplify reparenting and initial allocation mm/list_lru: code clean up for reparenting mm/list_lru: don't export list_lru_add mm/list_lru: don't pass unnecessary key parameters kasan: add kunit tests for kmalloc_track_caller, kmalloc_node_track_caller kasan: change kasan_atomics kunit test as KUNIT_CASE_SLOW kasan: use EXPORT_SYMBOL_IF_KUNIT to export symbols ...	2024-11-23 09:58:07 -08:00

Linus Torvalds	06afb0f361	tracing updates for v6.13: ... - Addition of faultable tracepoints There's a tracepoint attached to both a system call entry and exit. This location is known to allow page faults. The tracepoints are called under an rcu_read_lock() which does not allow faults that can sleep. This limits the ability of tracepoint handlers to page fault in user space system call parameters. Now these tracepoints have been made "faultable", allowing the callbacks to fault in user space parameters and record them. Note, only the infrastructure has been implemented. The consumers (perf, ftrace, BPF) now need to have their code modified to allow faults. - Fix up of BPF code for the tracepoint faultable logic - Update tracepoints to use the new static branch API - Remove trace_*_rcuidle() variants and the SRCU protection they used - Remove unused TRACE_EVENT_FL_FILTERED logic - Replace strncpy() with strscpy() and memcpy() - Use replace per_cpu_ptr(smp_processor_id()) with this_cpu_ptr() - Fix perf events to not duplicate samples when tracing is enabled - Replace atomic64_add_return(1, counter) with atomic64_inc_return(counter) - Make stack trace buffer 4K instead of PAGE_SIZE - Remove TRACE_FLAG_IRQS_NOSUPPORT flag as it was never used - Get the true return address for function tracer when function graph tracer is also running. When function_graph trace is running along with function tracer, the parent function of the function tracer sometimes is "return_to_handler", which is the function graph trampoline to record the exit of the function. Use existing logic that calls into the fgraph infrastructure to find the real return address. - Remove (un)regfunc pointers out of tracepoint structure - Added last minute bug fix for setting pending modules in stack function filter. echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter Would cause a kernel NULL dereference. - Minor clean ups -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZz6dehQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qlQsAP9aB0XGUV3UykvjZuKK84VDZ26a2hZH X2JDYsNA4luuPAEAz/BG2rnslfMZ04WTMAl8h1eh10lxcuHG0wQMHVBXIwI= =lzb5 -----END PGP SIGNATURE----- Merge tag 'trace-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Addition of faultable tracepoints There's a tracepoint attached to both a system call entry and exit.

Linus Torvalds	341d041daa	iommufd 6.13 merge window pull ... Several new features and uAPI for iommufd: - IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing memory for an iommu mapping. To date VFIO/iommufd have used VMA's and pin_user_pages(), this now allows using memfds and memfd_pin_folios(). Notably this creates a pure folio path from the memfd to the iommu page table where memory is never broken down to PAGE_SIZE. - IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between two processes. Combined with the above this allows iommufd to support a VMM re-start using exec() where something like qemu would exec() a new version of itself and fd pass the memfds/iommufd/etc to the new process. The memfd allows DMA access to the memory to continue while the new process is getting setup, and the CHANGE_PROCESS updates all the accounting. - Support for fault reporting to userspace on non-PRI HW, such as ARM stall-mode embedded devices. - IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed virtual iommu. This will be used by VMMs to access hardware features that are contained with in a VM. The first use is to inform the kernel of the virtual SID to physical SID mapping when issuing SID based invalidation on ARM. Further uses will tie HW features that are directly accessed by the VM, such as invalidation queue assignment and others. - IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual device to physical device within a VIOMMU. Minimially this is used to translate VM issued cache invalidation commands from virtual to physical device IDs. - Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work with the VIOMMU - ARM SMMuv3 support for nested translation. Using the VIOMMU and VDEVICE the driver can model this HW's behavior for nested translation. This includes a shared branch from Will. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZzzKKwAKCRCFwuHvBreF YaCMAQDOQAgw87eUYKnY7vFodlsTUA2E8uSxDmk6nPWySd0NKwD/flOP85MdEs9O Ot+RoL4/J3IyNH+eg5kN68odmx4mAw8= =ec8x -----END PGP SIGNATURE----- Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd updates from Jason Gunthorpe: "Several new features and uAPI for iommufd: - IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing memory for an iommu mapping.

Linus Torvalds	fcc79e1714	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 Drivers ------- - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic, Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the IRQs and queues to NAPI IDs, allowing busy polling and better introspection. - Ethernet high-speed NICs: - nVidia/Mellanox: - mlx5: - a large refactor to implement support for cross E-Switch scheduling - refactor H/W conter management to let it scale better - H/W GRO cleanups - Intel (100G, ice):: - adds support for ethtool reset - implement support for per TX queue H/W shaping - AMD/Solarflare: - implement per device queue stats support - Broadcom (bnxt): - improve wildcard l4proto on IPv4/IPv6 ntuple rules - Marvell Octeon: - Adds representor support for each Resource Virtualization Unit (RVU) device. - Hisilicon: - adds support for the BMC Gigabit Ethernet - IBM (EMAC): - driver cleanup and modernization - Cisco (VIC): - raise the queues number limit to 256 - Ethernet virtual: - Google vNIC: - implements page pool support - macsec: - inherit lower device's features and TSO limits when offloading - virtio_net: - enable premapped mode by default - support for XDP socket(AF_XDP) zerocopy TX - wireguard: - set the TSO max size to be GSO_MAX_SIZE, to aggregate larger packets. - Ethernet NICs embedded and virtual: - Broadcom ASP: - enable software timestamping - Freescale: - add enetc4 PF driver - MediaTek: Airoha SoC: - implement BQL support - RealTek r8169: - enable TSO by default on r8168/r8125 - implement extended ethtool stats - Renesas AVB: - enable TX checksum offload - Synopsys (stmmac): - support header splitting for vlan tagged packets - move common code for DWMAC4 and DWXGMAC into a separate FPE module. - Add the dwmac driver support for T-HEAD TH1520 SoC - Synopsys (xpcs): - driver refactor and cleanup - TI: - icssg_prueth: add VLAN offload support - Xilinx emaclite: - adds clock support - Ethernet switches: - Microchip: - implement support for the lan969x Ethernet switch family - add LAN9646 switch support to KSZ DSA driver - Ethernet PHYs: - Marvel: 88q2x: enable auto negotiation - Microchip: add support for LAN865X Rev B1 and LAN867X Rev C1/C2 - PTP: - Add support for the Amazon virtual clock device - Add PtP driver for s390 clocks - WiFi: - mac80211 - EHT 1024 aggregation size for transmissions - new operation to indicate that a new interface is to be added - support radio separation of multi-band devices - move wireless extension spy implementation to libiw - Broadcom: - brcmfmac: optional LPO clock support - Microchip: - add support for Atmel WILC3000 - Qualcomm (ath12k): - firmware coredump collection support - add debugfs support for a multitude of statistics - Qualcomm (ath5k): - Arcadyan ARV45XX AR2417 & Gigaset SX76[23] AR241[34]A support - Realtek: - rtw88: 8821au and 8812au USB adapters support - rtw89: add thermal protection - rtw89: fine tune BT-coexsitence to improve user experience - rtw89: firmware secure boot for WiFi 6 chip - Bluetooth - add Qualcomm WCN785x support for ids Foxconn 0xe0fc/0xe0f3 and 0x13d3:0x3623 - add Realtek RTL8852BE support for id Foxconn 0xe123 - add MediaTek MT7920 support for wireless module ids - btintel_pcie: add handshake between driver and firmware - btintel_pcie: add recovery mechanism - btnxpuart: add GPIO support to power save feature Signed-off-by: Paolo Abeni <pabeni@redhat.com> -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEEg1AjqC77wbdLX2LbKSR5jcyPE6QFAmc8sukSHHBhYmVuaUBy ZWRoYXQuY29tAAoJECkkeY3MjxOkLEYQAIMM6Qjh0bh3Byr3gOS1xZzXG+APLjP4 9Jr0p3i+X53i90jvVqzeVO5FTc95MVHSKZ3kvPkDMXSLUaEJxocNHCI5Dzl/2/qL wWdpUB6/ou+jKB4Bn6Z8OvVODT7qrr0tVa9M2/fuKWrIsOU/ntIhG8EhnGddk5U/ vKPSf5PUIb81uNRnF58VusY3wrT1dEoh9VfJYxL+ST+inPxjEAMy6Y+lmlsjGaSX jrS+Pp9KYiUwl3Qt0AQs+cG4OHkJdjbnChrfosWwpkiyddO8klVq06+wX/TiSzfF b9VZtBfy/GZs3lkE1mQkcILdtX5pP3YHQdpsuxFfVI0JHVszx2ck7WdoRux/8F0v kKZsYcO7bH9I1wMFP66Ff9hIbdEQaeucK+KdDkXyPNMfP91Vzmfjii8IBxOC36Ie BbOeFUrXyTxxJ2u0vf/X9JtIq8bcrkNrSd1n1jlGPMqG3FVzsY95+Oi4qfsyeUbl lS1PlVTqPMPFdX54HnxM3y2rJjhd7iXhkvmtuXNjRFThXlOiK3maAPWlM1aZ3b8u Vjs4JFUsW0tleZG+RzANjsGjXbf7AiPUGLZt+acem0K+fcjG4i5aGIAJrxwa/ORx eG74IZRt5cOI371W7gNLGHjwnuge8tFPgOWcRP2eozNm7jvMYALBejYS7eWUTvaf THcvVM+bupEZ =GzPr -----END PGP SIGNATURE----- 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.

Linus Torvalds	9c39d5ab45	soc: devicetree updates for 6.13 ... This release adds the devicetree files for an impressive number of new SoC variants, though as expected these are all related to others we already support: - The microchip sam9x7 devicetree is now added, after the device driver and platform code has already made it in. This is likely the last ARMv5 (!) platform to ever get added, updating the 20+ year old at91/sam9 platform wtih DDR3 memory and gigabit ethernet. - On the Apple platform, there are now devicetree files for a number of A-series SoCs in addition to the M-series ones, these are used primarily in phones and tablets, but are closely related to the already supported chips. - Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older Samsung Galaxy phones. - Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops. - Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet chips, still using the older ARMv8.0 cores from RK3328/RK3399 but with a newer process and other improvements from the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just lower-cost versions of their normal counterparts. - TI J742S2 is a feature-reduced version of the J784s4 industrial/automotive SoC, with fewer CPU cores. - Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM (Cortex-A53) core, at this point support is only added for running on the RISC-V side on the LicheeRV Nano board. A total of 92 new .dts files describing individual machines is added, which must be a new record. The majority of these is for the newly added chips above, notably all the Apple phones and tablets. The other new machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.

So I expect you will get a part of this tree also via the iio pull request for 6.13-rc1 (tag pwm/duty_offset-for-6.13-rc1). Otherwise it's the usual collection of fixes, cleanups and dt doc updates.

Linus Torvalds	8f7c8b88bd	sched_ext: Change for v6.13 ... - Improve the default select_cpu() implementation making it topology aware and handle WAKE_SYNC better. - set_arg_maybe_null() was used to inform the verifier which ops args could be NULL in a rather hackish way. Use the new __nullable CFI stub tags instead. - On Sapphire Rapids multi-socket systems, a BPF scheduler, by hammering on the same queue across sockets, could live-lock the system to the point where the system couldn't make reasonable forward progress. This could lead to soft-lockup triggered resets or stalling out bypass mode switch and thus BPF scheduler ejection for tens of minutes if not hours. After trying a number of mitigations, the following set worked reliably: - Injecting artificial cpu_relax() loops in two places while sched_ext is trying to turn on the bypass mode. - Triggering scheduler ejection when soft-lockup detection is imminent (a quarter of threshold left). While not the prettiest, the impact both in terms of code complexity and overhead is minimal. - A common complaint on the API is the overuse of the word "dispatch" and the confusion around "consume". This is due to how the dispatch queues became more generic over time. Rename the affected kfuncs for clarity. Thanks to BPF's compatibility features, this change can be made in a way that's both forward and backward compatible.

Linus Torvalds	bf9aa14fc5	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.

Linus Torvalds	5c2b050848	A set of updates for the interrupt subsystem: ... - Tree wide: * Make nr_irqs static to the core code and provide accessor functions to remove existing and prevent future aliasing problems with local variables or function arguments of the same name. - Core code: * Prevent freeing an interrupt in the devres code which is not managed by devres in the first place. * Use seq_put_decimal_ull_width() for decimal values output in /proc/interrupts which increases performance significantly as it avoids parsing the format strings over and over. * Optimize raising the timer and hrtimer soft interrupts by using the 'set bit only' variants instead of the combined version which checks whether ksoftirqd should be woken up. The latter is a pointless exercise as both soft interrupts are raised in the context of the timer interrupt and therefore never wake up ksoftirqd. * Delegate timer/hrtimer soft interrupt processing to a dedicated thread on RT. Timer and hrtimer soft interrupts are always processed in ksoftirqd on RT enabled kernels. This can lead to high latencies when other soft interrupts are delegated to ksoftirqd as well. The separate thread allows to run them seperately under a RT scheduling policy to reduce the latency overhead. - Drivers: * New drivers or extensions of existing drivers to support Renesas RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt chips * Support for multi-cluster GICs on MIPS.

Core code: - Prevent freeing an interrupt in the devres code which is not managed by devres in the first place. - Use seq_put_decimal_ull_width() for decimal values output in /proc/interrupts which increases performance significantly as it avoids parsing the format strings over and over. - Optimize raising the timer and hrtimer soft interrupts by using the 'set bit only' variants instead of the combined version which checks whether ksoftirqd should be woken up. The latter is a pointless exercise as both soft interrupts are raised in the context of the timer interrupt and therefore never wake up ksoftirqd. - Delegate timer/hrtimer soft interrupt processing to a dedicated thread on RT. Timer and hrtimer soft interrupts are always processed in ksoftirqd on RT enabled kernels. This can lead to high latencies when other soft interrupts are delegated to ksoftirqd as well. The separate thread allows to run them seperately under a RT scheduling policy to reduce the latency overhead. Drivers: - New drivers or extensions of existing drivers to support Renesas RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt chips - Support for multi-cluster GICs on MIPS.

Linus Torvalds	8cdf2d1903	RCU pull request for v6.13 ... SRCU: - Introduction of the new SRCU-lite flavour with a new pair of srcu_read_[un]lock_lite() APIs. In practice the read side using this flavour becomes lighter by removing a full memory barrier on LOCK and a full memory barrier on UNLOCK. This comes at the expense of a higher latency write side with two (in the best case of a snaphot of unused read-sides) or more RCU grace periods on the update side which now assumes by itself the whole full ordering guarantee against the LOCK/UNLOCK counters on both indexes, along with the accesses performed inside. Uretprobes is a known potential user. Note this doesn't replace the default normal flavour of SRCU which still behaves the same as usual. - Add testing of SRCU-lite through rcutorture and rcuscale - Various cleanups on the way. FIXES: - Allow short-circuiting RCU-TASKS-RUDE grace periods on architectures that have sane noinstr boundaries forbidding tracing on low-level idle and kernel entry code. RCU-TASKS is enough on such configurations because it involves an RCU grace period that waits for all idle tasks to either schedule out voluntarily or enter into RCU unwatched noinstr code. - Allow and test start_poll_synchronize_rcu() with IRQs disabled. - Mention rcuog kthreads in relevant documentation and Kconfig help - Various fixes and consolidations RCUTORTURE: - Add --no-affinity on tools to leave the affinity setting of guests up to the user. - Add guest_os_delay parameter to rcuscale for better warm-up control. - Fix and improve some rcuscale error handling. - Various cleanups and fixes STALL: - Remove dead code - Stop dumping tasks if a stalled grace period eventually ended midway as that only produces confusing output. - Optimize detection of stalling CPUs and avoid useless node locking otherwise. NOCB: - Fix rcu_barrier() hang due to a race against callbacks deoffloading. This is not yet used, except by rcutorture, and waits for its promised cpusets interface. - Remove leftover function declaration -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEd76+gtGM8MbftQlOhSRUR1COjHcFAmc6gP0ACgkQhSRUR1CO jHcHfw/5AWg5wiapwJtLO9KNdtELflTTbT/NhhqwYVReHnOSvtPNwWgo984T3jYJ xikE4Ccn5Nu4zJVbTOtmwJ/RP6WWP1I28LgoTCdcz9BB9b+CRLogV/dR5r5uZbhD +jqXRAzDhEifR0pcfSK28MkXoh+puXMg4C78f7xtT1Oe3Gr67RLf6xvE59gHJrDg QrPStdwhOn2bhmbKcflw1bHYqpypL09P2WHuRLmsJJUMUGIHTohK05lJOkD3hV9g HTxOecNmeF/r8NyN8l/ERJgKmwDukIG02xih8UMEtqDEl04IxZFHbCfB6yyIsKDT fTFxnRCHnm/PxIKRA5ENvyg/6uArMJ0xuSTZRG4K5v0nx7okR8gbCPmwiwn1m5w3 +/oppjCmG/gRgyiOytuEGKfaN9q/oJqQgeS7j8WruWj9V68FYUKr6COfQByw0xOc H6ftaLGeFHgHxk3nua2wFrfMtQhucYAMGAlVK82yd7Q1EFW47kzleO8w/HSvfrBt trX+9HZ77GVVmREJMstnIWRr5mbPtUf8yRZdA5bBrlEYz0A/ToNaFACid0fsaMC2 Dbo9Q+wDqL2wwOpjZy+MA3k1IVyDdUTuOQmPt57LmFTxUNZ+AQQlJcrhrUqWVvdM Nne2EHdqCHADKd7g3i17HtvpTsapz+Qakpzx8UsPqNtfo1DSd5A= =MWrw -----END PGP SIGNATURE----- Merge tag 'rcu.release.v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux Pull RCU updates from Frederic Weisbecker: "SRCU: - Introduction of the new SRCU-lite flavour with a new pair of srcu_read_[un]lock_lite() APIs.
