He has been active reviewing Rust code in the mailing list, and he already is a formal reviewer of the Rust PHY library and the two PHY drivers. In addition, he is also part of several upstream Rust teams: compiler-contributors team (contributors to the Rust compiler on a regular basis), libs-contributors (contributors to the Rust standard library on a regular basis), crate-maintainers (maintainers of official Rust crates), the binary size working group and the Rust for Linux ping group. His expertise with the language will be very useful to have around in the future if Rust keeps growing within the kernel, thus add him to the `RUST` entry as a reviewer.

For example, Xilinx Alveo V70 AI Accelerator devices. https://www.xilinx.com/applications/data-center/v70.html The QDMA subsystem is used in conjunction with the PCI Express IP block to provide high performance data transfer between host memory and the card's DMA subsystem. +-------+ +-------+ +-----------+ PCIe | | | | | | Tx/Rx | | | | AXI | | <=======> | PCIE | <===> | QDMA | <====>| User Logic| | | | | | | +-------+ +-------+ +-----------+ The primary mechanism to transfer data using the QDMA is for the QDMA engine to operate on instructions (descriptors) provided by the host operating system. Using the descriptors, the QDMA can move data in both the Host to Card (H2C) direction, or the Card to Host (C2H) direction. The QDMA provides a per-queue basis option whether DMA traffic goes to an AXI4 memory map (MM) interface or to an AXI4-Stream interface.

This can impact receiver's ability to capture signals accurately. Hence, as signal compensation is achieved through appropriate lane equalization, apply lane equalization settings at both transmitter and receiver which results in an increase in the PCIe signal strength. While at it, modify the pcie-tegra194 driver to make use of the common GEN3_EQ_CONTROL_OFF definitions in pcie-designware.h.

| | | | | | | | | | | | | | | | | | | | Implement a new scheduler class sched_ext (SCX), which allows scheduling policies to be implemented as BPF programs to achieve the following: 1. Ease of experimentation and exploration: Enabling rapid iteration of new scheduling policies. 2. Customization: Building application-specific schedulers which implement policies that are not applicable to general-purpose schedulers. 3. Rapid scheduler deployments: Non-disruptive swap outs of scheduling policies in production environments. sched_ext leverages BPF’s struct_ops feature to define a structure which exports function callbacks and flags to BPF programs that wish to implement scheduling policies. The struct_ops structure exported by sched_ext is struct sched_ext_ops, and is conceptually similar to struct sched_class. The role of sched_ext is to map the complex sched_class callbacks to the more simple and ergonomic struct sched_ext_ops callbacks. For more detailed discussion on the motivations and overview, please refer to the cover letter. Later patches will also add several example schedulers and documentation. This patch implements the minimum core framework to enable implementation of BPF schedulers. Subsequent patches will gradually add functionalities including safety guarantee mechanisms, nohz and cgroup support. include/linux/sched/ext.h defines struct sched_ext_ops. With the comment on top, each operation should be self-explanatory. The followings are worth noting: - Both "sched_ext" and its shorthand "scx" are used. If the identifier already has "sched" in it, "ext" is used; otherwise, "scx". - In sched_ext_ops, only .name is mandatory. Every operation is optional and if omitted a simple but functional default behavior is provided. - A new policy constant SCHED_EXT is added and a task can select sched_ext by invoking sched_setscheduler(2) with the new policy constant. However, if the BPF scheduler is not loaded, SCHED_EXT is the same as SCHED_NORMAL and the task is scheduled by CFS. When the BPF scheduler is loaded, all tasks which have the SCHED_EXT policy are switched to sched_ext. - To bridge the workflow imbalance between the scheduler core and sched_ext_ops callbacks, sched_ext uses simple FIFOs called dispatch queues (dsq's). By default, there is one global dsq (SCX_DSQ_GLOBAL), and one local per-CPU dsq (SCX_DSQ_LOCAL). SCX_DSQ_GLOBAL is provided for convenience and need not be used by a scheduler that doesn't require it. SCX_DSQ_LOCAL is the per-CPU FIFO that sched_ext pulls from when putting the next task on the CPU. The BPF scheduler can manage an arbitrary number of dsq's using scx_bpf_create_dsq() and scx_bpf_destroy_dsq(). - sched_ext guarantees system integrity no matter what the BPF scheduler does. To enable this, each task's ownership is tracked through p->scx.ops_state and all tasks are put on scx_tasks list. The disable path can always recover and revert all tasks back to CFS. See p->scx.ops_state and scx_tasks. - A task is not tied to its rq while enqueued. This decouples CPU selection from queueing and allows sharing a scheduling queue across an arbitrary subset of CPUs. This adds some complexities as a task may need to be bounced between rq's right before it starts executing. See dispatch_to_local_dsq() and move_task_to_local_dsq(). - One complication that arises from the above weak association between task and rq is that synchronizing with dequeue() gets complicated as dequeue() may happen anytime while the task is enqueued and the dispatch path might need to release the rq lock to transfer the task. Solving this requires a bit of complexity. See the logic around p->scx.sticky_cpu and p->scx.ops_qseq. - Both enable and disable paths are a bit complicated. The enable path switches all tasks without blocking to avoid issues which can arise from partially switched states (e.g. the switching task itself being starved). The disable path can't trust the BPF scheduler at all, so it also has to guarantee forward progress without blocking. See scx_ops_enable() and scx_ops_disable_workfn(). - When sched_ext is disabled, static_branches are used to shut down the entry points from hot paths. v7: - scx_ops_bypass() was incorrectly and unnecessarily trying to grab scx_ops_enable_mutex which can lead to deadlocks in the disable path. Fixed. - Fixed TASK_DEAD handling bug in scx_ops_enable() path which could lead to use-after-free. - Consolidated per-cpu variable usages and other cleanups. v6: - SCX_NR_ONLINE_OPS replaced with SCX_OPI_*_BEGIN/END so that multiple groups can be expressed. Later CPU hotplug operations are put into their own group. - SCX_OPS_DISABLING state is replaced with the new bypass mechanism which allows temporarily putting the system into simple FIFO scheduling mode bypassing the BPF scheduler. In addition to the shut down path, this will also be used to isolate the BPF scheduler across PM events. Enabling and disabling the bypass mode requires iterating all runnable tasks. rq->scx.runnable_list addition is moved from the later watchdog patch. - ops.prep_enable() is replaced with ops.init_task() and ops.enable/disable() are now called whenever the task enters and leaves sched_ext instead of when the task becomes schedulable on sched_ext and stops being so. A new operation - ops.exit_task() - is called when the task stops being schedulable on sched_ext. - scx_bpf_dispatch() can now be called from ops.select_cpu() too. This removes the need for communicating local dispatch decision made by ops.select_cpu() to ops.enqueue() via per-task storage. SCX_KF_SELECT_CPU is added to support the change. - SCX_TASK_ENQ_LOCAL which told the BPF scheudler that scx_select_cpu_dfl() wants the task to be dispatched to the local DSQ was removed. Instead, scx_bpf_select_cpu_dfl() now dispatches directly if it finds a suitable idle CPU. If such behavior is not desired, users can use scx_bpf_select_cpu_dfl() which returns the verdict in a bool out param. - scx_select_cpu_dfl() was mishandling WAKE_SYNC and could end up queueing many tasks on a local DSQ which makes tasks to execute in order while other CPUs stay idle which made some hackbench numbers really bad. Fixed. - The current state of sched_ext can now be monitored through files under /sys/sched_ext instead of /sys/kernel/debug/sched/ext. This is to enable monitoring on kernels which don't enable debugfs. - sched_ext wasn't telling BPF that ops.dispatch()'s @prev argument may be NULL and a BPF scheduler which derefs the pointer without checking could crash the kernel. Tell BPF. This is currently a bit ugly. A better way to annotate this is expected in the future. - scx_exit_info updated to carry pointers to message buffers instead of embedding them directly. This decouples buffer sizes from API so that they can be changed without breaking compatibility. - exit_code added to scx_exit_info. This is used to indicate different exit conditions on non-error exits and will be used to handle e.g. CPU hotplugs. - The patch "sched_ext: Allow BPF schedulers to switch all eligible tasks into sched_ext" is folded in and the interface is changed so that partial switching is indicated with a new ops flag %SCX_OPS_SWITCH_PARTIAL. This makes scx_bpf_switch_all() unnecessasry and in turn SCX_KF_INIT. ops.init() is now called with SCX_KF_SLEEPABLE. - Code reorganized so that only the parts necessary to integrate with the rest of the kernel are in the header files. - Changes to reflect the BPF and other kernel changes including the addition of bpf_sched_ext_ops.cfi_stubs. v5: - To accommodate 32bit configs, p->scx.ops_state is now atomic_long_t instead of atomic64_t and scx_dsp_buf_ent.qseq which uses load_acquire/store_release is now unsigned long instead of u64. - Fix the bug where bpf_scx_btf_struct_access() was allowing write access to arbitrary fields. - Distinguish kfuncs which can be called from any sched_ext ops and from anywhere. e.g. scx_bpf_pick_idle_cpu() can now be called only from sched_ext ops. - Rename "type" to "kind" in scx_exit_info to make it easier to use on languages in which "type" is a reserved keyword. - Since cff9b2332ab7 ("kernel/sched: Modify initial boot task idle setup"), PF_IDLE is not set on idle tasks which haven't been online yet which made scx_task_iter_next_filtered() include those idle tasks in iterations leading to oopses. Update scx_task_iter_next_filtered() to directly test p->sched_class against idle_sched_class instead of using is_idle_task() which tests PF_IDLE. - Other updates to match upstream changes such as adding const to set_cpumask() param and renaming check_preempt_curr() to wakeup_preempt(). v4: - SCHED_CHANGE_BLOCK replaced with the previous sched_deq_and_put_task()/sched_enq_and_set_tsak() pair. This is because upstream is adaopting a different generic cleanup mechanism. Once that lands, the code will be adapted accordingly. - task_on_scx() used to test whether a task should be switched into SCX, which is confusing. Renamed to task_should_scx(). task_on_scx() now tests whether a task is currently on SCX. - scx_has_idle_cpus is barely used anymore and replaced with direct check on the idle cpumask. - SCX_PICK_IDLE_CORE added and scx_pick_idle_cpu() improved to prefer fully idle cores. - ops.enable() now sees up-to-date p->scx.weight value. - ttwu_queue path is disabled for tasks on SCX to avoid confusing BPF schedulers expecting ->select_cpu() call. - Use cpu_smt_mask() instead of topology_sibling_cpumask() like the rest of the scheduler. v3: - ops.set_weight() added to allow BPF schedulers to track weight changes without polling p->scx.weight. - move_task_to_local_dsq() was losing SCX-specific enq_flags when enqueueing the task on the target dsq because it goes through activate_task() which loses the upper 32bit of the flags. Carry the flags through rq->scx.extra_enq_flags. - scx_bpf_dispatch(), scx_bpf_pick_idle_cpu(), scx_bpf_task_running() and scx_bpf_task_cpu() now use the new KF_RCU instead of KF_TRUSTED_ARGS to make it easier for BPF schedulers to call them. - The kfunc helper access control mechanism implemented through sched_ext_entity.kf_mask is improved. Now SCX_CALL_OP*() is always used when invoking scx_ops operations. v2: - balance_scx_on_up() is dropped. Instead, on UP, balance_scx() is called from put_prev_taks_scx() and pick_next_task_scx() as necessary. To determine whether balance_scx() should be called from put_prev_task_scx(), SCX_TASK_DEQD_FOR_SLEEP flag is added. See the comment in put_prev_task_scx() for details. - sched_deq_and_put_task() / sched_enq_and_set_task() sequences replaced with SCHED_CHANGE_BLOCK(). - Unused all_dsqs list removed. This was a left-over from previous iterations. - p->scx.kf_mask is added to track and enforce which kfunc helpers are allowed. Also, init/exit sequences are updated to make some kfuncs always safe to call regardless of the current BPF scheduler state. Combined, this should make all the kfuncs safe. - BPF now supports sleepable struct_ops operations. Hacky workaround removed and operations and kfunc helpers are tagged appropriately. - BPF now supports bitmask / cpumask helpers. scx_bpf_get_idle_cpumask() and friends are added so that BPF schedulers can use the idle masks with the generic helpers. This replaces the hacky kfunc helpers added by a separate patch in V1. - CONFIG_SCHED_CLASS_EXT can no longer be enabled if SCHED_CORE is enabled. This restriction will be removed by a later patch which adds core-sched support. - Add MAINTAINERS entries and other misc changes.

It is similar to existing 'no_caller_saved_registers' attribute in GCC/LLVM with a provision for backward compatibility. It allows compilers generate more efficient BPF code assuming the verifier or JITs will inline or partially inline a helper/kfunc with such attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast, bpf_get_smp_processor_id are the first set of such helpers. - Harden and extend ELF build ID parsing logic. When called from sleepable context the relevants parts of ELF file will be read to find and fetch .note.gnu.build-id information. Also harden the logic to avoid TOCTOU, overflow, out-of-bounds problems. - Improvements and fixes for sched-ext: - Allow passing BPF iterators as kfunc arguments - Make the pointer returned from iter_next method trusted - Fix x86 JIT convergence issue due to growing/shrinking conditional jumps in variable length encoding - BPF_LSM related: - Introduce few VFS kfuncs and consolidate them in fs/bpf_fs_kfuncs.c - Enforce correct range of return values from certain LSM hooks - Disallow attaching to other LSM hooks - Prerequisite work for upcoming Qdisc in BPF: - Allow kptrs in program provided structs - Support for gen_epilogue in verifier_ops - Important fixes: - Fix uprobe multi pid filter check - Fix bpf_strtol and bpf_strtoul helpers - Track equal scalars history on per-instruction level - Fix tailcall hierarchy on x86 and arm64 - Fix signed division overflow to prevent INT_MIN/-1 trap on x86 - Fix get kernel stack in BPF progs attached to tracepoint:syscall - Selftests: - Add uprobe bench/stress tool - Generate file dependencies to drastically improve re-build time - Match JIT-ed and BPF asm with __xlated/__jited keywords - Convert older tests to test_progs framework - Add support for RISC-V - Few fixes when BPF programs are compiled with GCC-BPF backend (support for GCC-BPF in BPF CI is ongoing in parallel) - Add traffic monitor - Enable cross compile and musl libc * tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (260 commits) btf: require pahole 1.21+ for DEBUG_INFO_BTF with default DWARF version btf: move pahole check in scripts/link-vmlinux.sh to lib/Kconfig.debug btf: remove redundant CONFIG_BPF test in scripts/link-vmlinux.sh bpf: Call the missed kfree() when there is no special field in btf bpf: Call the missed btf_record_free() when map creation fails selftests/bpf: Add a test case to write mtu result into .rodata selftests/bpf: Add a test case to write strtol result into .rodata selftests/bpf: Rename ARG_PTR_TO_LONG test description selftests/bpf: Fix ARG_PTR_TO_LONG {half-,}uninitialized test bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error bpf: Improve check_raw_mode_ok test for MEM_UNINIT-tagged types bpf: Fix helper writes to read-only maps bpf: Remove truncation test in bpf_strtol and bpf_strtoul helpers bpf: Fix bpf_strtol and bpf_strtoul helpers for 32bit selftests/bpf: Add tests for sdiv/smod overflow cases bpf: Fix a sdiv overflow issue libbpf: Add bpf_object__token_fd accessor docs/bpf: Add missing BPF program types to docs docs/bpf: Add constant values for linkages bpf: Use fake pt_regs when doing bpf syscall tracepoint tracing ...

Akinobu Mita seems to be actively maintaining it, so, let's add the file under FAULT INJECTION SUPPORT section.

XZ Embedded, the upstream project, switched from public domain to the BSD Zero Clause License (0BSD). Now matching SPDX license identifiers can be added. Documentation was revised. Fix syntax errors in kernel-doc comments in <linux/xz.h>. The xz_dec API docs from <linux/xz.h> are now included in Documentation/staging/xz.rst. The new ARM64 and RISC-V filters can be used for kernel decompression if CONFIG_EFI_ZBOOT=y. The filters can be used by Squashfs too. (Userspace Squashfs-tools already had the ARM64 filter support committed but it was reverted due to backdoor fears. I try to get ARM64 and RISC-V filter support added to Squashfs-tools somewhat soon.) Account for the default threading change made in the xz command line tool version 5.6.0. Tweak kernel compression options for archs that support XZ compressed kernel. This patch (of 16): I have been the maintainer of the upstream project since I submitted the code to Linux in 2010 but I forgot to add myself to MAINTAINERS.

This provides fundamental VMA operations whose API is defined in mm/vma.h, while stubbing out superfluous functionality. This exists as a proof-of-concept, with the test implementation functional and sufficient to allow userland compilation of vma.c, but containing only cursory tests to demonstrate basic functionality.
