git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "Kthreads affinity follow either of 4 existing different patterns: 1) Per-CPU kthreads must stay affine to a single CPU and never execute relevant code on any other CPU. This is currently handled by smpboot code which takes care of CPU-hotplug operations. Affinity here is a correctness constraint. 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't run anywhere else. The affinity is set through kthread_bind_mask() and the subsystem takes care by itself to handle CPU-hotplug operations. Affinity here is assumed to be a correctness constraint. 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This is not a correctness constraint but merely a preference in terms of memory locality. kswapd and kcompactd both fall into this category. The affinity is set manually like for any other task and CPU-hotplug is supposed to be handled by the relevant subsystem so that the task is properly reaffined whenever a given CPU from the node comes up. Also care should be taken so that the node affinity doesn't cross isolated (nohz_full) cpumask boundaries. 4) Similar to the previous point except kthreads have a _preferred_ affinity different than a node. Both RCU boost kthreads and RCU exp kworkers fall into this category as they refer to "RCU nodes" from a distinctly distributed tree. Currently the preferred affinity patterns (3 and 4) have at least 4 identified users, with more or less success when it comes to handle CPU-hotplug operations and CPU isolation. Each of which do it in its own ad-hoc way. This is an infrastructure proposal to handle this with the following API changes: - kthread_create_on_node() automatically affines the created kthread to its target node unless it has been set as per-cpu or bound with kthread_bind[_mask]() before the first wake-up. - kthread_affine_preferred() is a new function that can be called right after kthread_create_on_node() to specify a preferred affinity different than the specified node. When the preferred affinity can't be applied because the possible targets are offline or isolated (nohz_full), the kthread is affine to the housekeeping CPUs (which means to all online CPUs most of the time or only the non-nohz_full CPUs when nohz_full= is set). kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been converted, along with a few old drivers. Summary of the changes: - Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu() - Introduce task_cpu_fallback_mask() that defines the default last resort affinity of a task to become nohz_full aware - Add some correctness check to ensure kthread_bind() is always called before the first kthread wake up. - Default affine kthread to its preferred node. - Convert kswapd / kcompactd and remove their halfway working ad-hoc affinity implementation - Implement kthreads preferred affinity - Unify kthread worker and kthread API's style - Convert RCU kthreads to the new API and remove the ad-hoc affinity implementation" * tag 'kthread-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: kthread: modify kernel-doc function name to match code rcu: Use kthread preferred affinity for RCU exp kworkers treewide: Introduce kthread_run_worker[_on_cpu]() kthread: Unify kthread_create_on_cpu() and kthread_create_worker_on_cpu() automatic format rcu: Use kthread preferred affinity for RCU boost kthread: Implement preferred affinity mm: Create/affine kswapd to its preferred node mm: Create/affine kcompactd to its preferred node kthread: Default affine kthread to its preferred NUMA node kthread: Make sure kthread hasn't started while binding it sched,arm64: Handle CPU isolation on last resort fallback rq selection arm64: Exclude nohz_full CPUs from 32bits el0 support lib: test_objpool: Use kthread_run_on_cpu() kallsyms: Use kthread_run_on_cpu() soc/qman: test: Use kthread_run_on_cpu() arm/bL_switcher: Use kthread_run_on_cpu()

2025-01-21Merge tag 'ftrace-v6.14' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Have fprobes built on top of function graph infrastructure The fprobe logic is an optimized kprobe that uses ftrace to attach to functions when a probe is needed at the start or end of the function. The fprobe and kretprobe logic implements a similar method as the function graph tracer to trace the end of the function. That is to hijack the return address and jump to a trampoline to do the trace when the function exits. To do this, a shadow stack needs to be created to store the original return address. Fprobes and function graph do this slightly differently. Fprobes (and kretprobes) has slots per callsite that are reserved to save the return address. This is fine when just a few points are traced. But users of fprobes, such as BPF programs, are starting to add many more locations, and this method does not scale. The function graph tracer was created to trace all functions in the kernel. In order to do this, when function graph tracing is started, every task gets its own shadow stack to hold the return address that is going to be traced. The function graph tracer has been updated to allow multiple users to use its infrastructure. Now have fprobes be one of those users. This will also allow for the fprobe and kretprobe methods to trace the return address to become obsolete. With new technologies like CFI that need to know about these methods of hijacking the return address, going toward a solution that has only one method of doing this will make the kernel less complex. - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Remove disabling of interrupts in the function graph tracer When function graph tracer was first introduced, it could race with interrupts and NMIs. To prevent that race, it would disable interrupts and not trace NMIs. But the code has changed to allow NMIs and also interrupts. This change was done a long time ago, but the disabling of interrupts was never removed. Remove the disabling of interrupts in the function graph tracer is it is not needed. This greatly improves its performance. - Allow the :mod: command to enable tracing module functions on the kernel command line. The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Because enabling function tracing can be done very early at boot up (before scheduling is enabled), the commands that can be done when function tracing is started is limited. Having the ":mod:" command to trace module functions as they are loaded is very useful. Update the kernel command line function filtering to allow it. * tag 'ftrace-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) ftrace: Implement :mod: cache filtering on kernel command line tracing: Adopt __free() and guard() for trace_fprobe.c bpf: Use ftrace_get_symaddr() for kprobe_multi probes ftrace: Add ftrace_get_symaddr to convert fentry_ip to symaddr Documentation: probes: Update fprobe on function-graph tracer selftests/ftrace: Add a test case for repeating register/unregister fprobe selftests: ftrace: Remove obsolate maxactive syntax check tracing/fprobe: Remove nr_maxactive from fprobe fprobe: Add fprobe_header encoding feature fprobe: Rewrite fprobe on function-graph tracer s390/tracing: Enable HAVE_FTRACE_GRAPH_FUNC ftrace: Add CONFIG_HAVE_FTRACE_GRAPH_FUNC bpf: Enable kprobe_multi feature if CONFIG_FPROBE is enabled tracing/fprobe: Enable fprobe events with CONFIG_DYNAMIC_FTRACE_WITH_ARGS tracing: Add ftrace_fill_perf_regs() for perf event tracing: Add ftrace_partial_regs() for converting ftrace_regs to pt_regs fprobe: Use ftrace_regs in fprobe exit handler fprobe: Use ftrace_regs in fprobe entry handler fgraph: Pass ftrace_regs to retfunc fgraph: Replace fgraph_ret_regs with ftrace_regs ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull interrupt subsystem updates from Thomas Gleixner: - Consolidate the machine_kexec_mask_interrupts() by providing a generic implementation and replacing the copy & pasta orgy in the relevant architectures. - Prevent unconditional operations on interrupt chips during kexec shutdown, which can trigger warnings in certain cases when the underlying interrupt has been shut down before. - Make the enforcement of interrupt handling in interrupt context unconditionally available, so that it actually works for non x86 related interrupt chips. The earlier enablement for ARM GIC chips set the required chip flag, but did not notice that the check was hidden behind a config switch which is not selected by ARM[64]. - Decrapify the handling of deferred interrupt affinity setting. Some interrupt chips require that affinity changes are made from the context of handling an interrupt to avoid certain race conditions. For x86 this was the default, but with interrupt remapping this requirement was lifted and a flag was introduced which tells the core code that affinity changes can be done in any context. Unrestricted affinity changes are the default for the majority of interrupt chips. RISCV has the requirement to add the deferred mode to one of it's interrupt controllers, but with the original implementation this would require to add the any context flag to all other RISC-V interrupt chips. That's backwards, so reverse the logic and require that chips, which need the deferred mode have to be marked accordingly. That avoids chasing the 'sane' chips and marking them. - Add multi-node support to the Loongarch AVEC interrupt controller driver. - The usual tiny cleanups, fixes and improvements all over the place. * tag 'irq-core-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/generic_chip: Export irq_gc_mask_disable_and_ack_set() genirq/timings: Add kernel-doc for a function parameter genirq: Remove IRQ_MOVE_PCNTXT and related code x86/apic: Convert to IRQCHIP_MOVE_DEFERRED genirq: Provide IRQCHIP_MOVE_DEFERRED hexagon: Remove GENERIC_PENDING_IRQ leftover ARC: Remove GENERIC_PENDING_IRQ genirq: Remove handle_enforce_irqctx() wrapper genirq: Make handle_enforce_irqctx() unconditionally available irqchip/loongarch-avec: Add multi-nodes topology support irqchip/ts4800: Replace seq_printf() by seq_puts() irqchip/ti-sci-inta : Add module build support irqchip/ti-sci-intr: Add module build support irqchip/irq-brcmstb-l2: Replace brcmstb_l2_mask_and_ack() by generic function irqchip: keystone: Use syscon_regmap_lookup_by_phandle_args genirq/kexec: Prevent redundant IRQ masking by checking state before shutdown kexec: Consolidate machine_kexec_mask_interrupts() implementation genirq: Reuse irq_thread_fn() for forced thread case genirq: Move irq_thread_fn() further up in the code
2025-01-21KVM: arm64: Flush hyp bss section after initialization of variables in bssLokesh Vutla
To determine CPU features during initialization, the nVHE hypervisor utilizes sanitized values of the host's CPU features registers. These values, stored in u64 idaa64*_el1_sys_val variables are updated by the kvm_hyp_init_symbols() function at EL1. To ensure EL2 visibility with the MMU off, the data cache needs to be flushed after these updates. However, individually flushing each variable using kvm_flush_dcache_to_poc() is inefficient. These cpu feature variables would be part of the bss section of the hypervisor. Hence, flush the entire bss section of hypervisor once the initialization is complete.

From the initial cover letter: : : "Here's another batch of NV-related patches, this time bringing in most : of the timer support for EL2 as well as nested guests. : : The code is pretty convoluted for a bunch of reasons: : : - FEAT_NV2 breaks the timer semantics by redirecting HW controls to : memory, meaning that a guest could setup a timer and never see it : firing until the next exit : : - We go try hard to reflect the timer state in memory, but that's not : great. : : - With FEAT_ECV, we can finally correctly emulate the virtual timer, : but this emulation is pretty costly : : - As a way to make things suck less, we handle timer reads as early as : possible, and only defer writes to the normal trap handling : : - Finally, some implementations are badly broken, and require some : hand-holding, irrespective of NV support. So we try and reuse the NV : infrastructure to make them usable. This could be further optimised, : but I'm running out of patience for this sort of HW. : : [...]" : .

2025-01-14KVM: arm64: nv: Apply RESx settings to sysreg reset valuesMarc Zyngier
While we have sanitisation in place for the guest sysregs, we lack that sanitisation out of reset. So some of the fields could be evaluated and not reflect their RESx status, which sounds like a very bad idea. Apply the RESx masks to the the sysreg file in two situations: - when going via a reset of the sysregs - after having computed the RESx masks Having this separate reset phase from the actual reset handling is a bit grotty, but we need to apply this after the ID registers are final.

2025-01-14KVM: arm64: nv: Always evaluate HCR_EL2 using sanitising accessorsMarc Zyngier
A lot of the NV code depends on HCR_EL2.{E2H,TGE}, and we assume in places that at least HCR_EL2.E2H is invariant for a given guest. However, we make a point in *not* using the sanitising accessor that would enforce this, and are at the mercy of the guest doing stupid things. Clearly, that's not good. Rework the HCR_EL2 accessors to use __vcpu_sys_reg() instead, guaranteeing that the RESx settings get applied, specially when HCR_EL2.E2H is evaluated. This results in fewer accessors overall. Huge thanks to Joey who spent a long time tracking this bug down.

2025-01-12KVM: arm64: Support trace filtering for guestsJames Clark
For nVHE, switch the filter value in and out if the Coresight driver asks for it. This will support filters for guests when sinks other than TRBE are used. For VHE, just write the filter directly to TRFCR_EL1 where trace can be used even with TRBE sinks.

2025-01-12KVM: arm64: coresight: Give TRBE enabled state to KVMJames Clark
Currently in nVHE, KVM has to check if TRBE is enabled on every guest switch even if it was never used. Because it's a debug feature and is more likely to not be used than used, give KVM the TRBE buffer status to allow a much simpler and faster do-nothing path in the hyp. Protected mode now disables trace regardless of TRBE (because trfcr_while_in_guest is always 0), which was not previously done. However, it continues to flush whenever the buffer is enabled regardless of the filter status. This avoids the hypothetical case of a host that had disabled the filter but not flushed which would arise if only doing the flush when the filter was enabled.

2025-01-12arm64/sysreg/tools: Move TRFCR definitions to sysregJames Clark
Convert TRFCR to automatic generation. Add separate definitions for ELx and EL2 as TRFCR_EL1 doesn't have CX. This also mirrors the previous definition so no code change is required. Also add TRFCR_EL12 which will start to be used in a later commit. Unfortunately, to avoid breaking the Perf build with duplicate definition errors, the tools copy of the sysreg.h header needs to be updated at the same time rather than the usual second commit. This is because the generated version of sysreg (arch/arm64/include/generated/asm/sysreg-defs.h), is currently shared and tools/ does not have its own copy.
