+===============
+BPF ring buffer
+===============
+
+This document describes BPF ring buffer design, API, and implementation details.
+
+.. contents::
+ :local:
+ :depth: 2
+
+Motivation
+----------
+
+There are two distinctive motivators for this work, which are not satisfied by
+existing perf buffer, which prompted creation of a new ring buffer
+implementation.
+
+- more efficient memory utilization by sharing ring buffer across CPUs;
+- preserving ordering of events that happen sequentially in time, even across
+ multiple CPUs (e.g., fork/exec/exit events for a task).
+
+These two problems are independent, but perf buffer fails to satisfy both.
+Both are a result of a choice to have per-CPU perf ring buffer. Both can be
+also solved by having an MPSC implementation of ring buffer. The ordering
+problem could technically be solved for perf buffer with some in-kernel
+counting, but given the first one requires an MPSC buffer, the same solution
+would solve the second problem automatically.
+
+Semantics and APIs
+------------------
+
+Single ring buffer is presented to BPF programs as an instance of BPF map of
+type ``BPF_MAP_TYPE_RINGBUF``. Two other alternatives considered, but
+ultimately rejected.
+
+One way would be to, similar to ``BPF_MAP_TYPE_PERF_EVENT_ARRAY``, make
+``BPF_MAP_TYPE_RINGBUF`` could represent an array of ring buffers, but not
+enforce "same CPU only" rule. This would be more familiar interface compatible
+with existing perf buffer use in BPF, but would fail if application needed more
+advanced logic to lookup ring buffer by arbitrary key.
+``BPF_MAP_TYPE_HASH_OF_MAPS`` addresses this with current approach.
+Additionally, given the performance of BPF ringbuf, many use cases would just
+opt into a simple single ring buffer shared among all CPUs, for which current
+approach would be an overkill.
+
+Another approach could introduce a new concept, alongside BPF map, to represent
+generic "container" object, which doesn't necessarily have key/value interface
+with lookup/update/delete operations. This approach would add a lot of extra
+infrastructure that has to be built for observability and verifier support. It
+would also add another concept that BPF developers would have to familiarize
+themselves with, new syntax in libbpf, etc. But then would really provide no
+additional benefits over the approach of using a map. ``BPF_MAP_TYPE_RINGBUF``
+doesn't support lookup/update/delete operations, but so doesn't few other map
+types (e.g., queue and stack; array doesn't support delete, etc).
+
+The approach chosen has an advantage of re-using existing BPF map
+infrastructure (introspection APIs in kernel, libbpf support, etc), being
+familiar concept (no need to teach users a new type of object in BPF program),
+and utilizing existing tooling (bpftool). For common scenario of using a single
+ring buffer for all CPUs, it's as simple and straightforward, as would be with
+a dedicated "container" object. On the other hand, by being a map, it can be
+combined with ``ARRAY_OF_MAPS`` and ``HASH_OF_MAPS`` map-in-maps to implement
+a wide variety of topologies, from one ring buffer for each CPU (e.g., as
+a replacement for perf buffer use cases), to a complicated application
+hashing/sharding of ring buffers (e.g., having a small pool of ring buffers
+with hashed task's tgid being a look up key to preserve order, but reduce
+contention).
+
+Key and value sizes are enforced to be zero. ``max_entries`` is used to specify
+the size of ring buffer and has to be a power of 2 value.
+
+There are a bunch of similarities between perf buffer
+(``BPF_MAP_TYPE_PERF_EVENT_ARRAY``) and new BPF ring buffer semantics:
+
+- variable-length records;
+- if there is no more space left in ring buffer, reservation fails, no
+ blocking;
+- memory-mappable data area for user-space applications for ease of
+ consumption and high performance;
+- epoll notifications for new incoming data;
+- but still the ability to do busy polling for new data to achieve the
+ lowest latency, if necessary.
+
+BPF ringbuf provides two sets of APIs to BPF programs:
+
+- ``bpf_ringbuf_output()`` allows to *copy* data from one place to a ring
+ buffer, similarly to ``bpf_perf_event_output()``;
+- ``bpf_ringbuf_reserve()``/``bpf_ringbuf_commit()``/``bpf_ringbuf_discard()``
+ APIs split the whole process into two steps. First, a fixed amount of space
+ is reserved. If successful, a pointer to a data inside ring buffer data
+ area is returned, which BPF programs can use similarly to a data inside
+ array/hash maps. Once ready, this piece of memory is either committed or
+ discarded. Discard is similar to commit, but makes consumer ignore the
+ record.
+
+``bpf_ringbuf_output()`` has disadvantage of incurring extra memory copy,
+because record has to be prepared in some other place first. But it allows to
+submit records of the length that's not known to verifier beforehand. It also
+closely matches ``bpf_perf_event_output()``, so will simplify migration
+significantly.
+
+``bpf_ringbuf_reserve()`` avoids the extra copy of memory by providing a memory
+pointer directly to ring buffer memory. In a lot of cases records are larger
+than BPF stack space allows, so many programs have use extra per-CPU array as
+a temporary heap for preparing sample. bpf_ringbuf_reserve() avoid this needs
+completely. But in exchange, it only allows a known constant size of memory to
+be reserved, such that verifier can verify that BPF program can't access memory
+outside its reserved record space. bpf_ringbuf_output(), while slightly slower
+due to extra memory copy, covers some use cases that are not suitable for
+``bpf_ringbuf_reserve()``.
+
+The difference between commit and discard is very small. Discard just marks
+a record as discarded, and such records are supposed to be ignored by consumer
+code. Discard is useful for some advanced use-cases, such as ensuring
+all-or-nothing multi-record submission, or emulating temporary
+``malloc()``/``free()`` within single BPF program invocation.
+
+Each reserved record is tracked by verifier through existing
+reference-tracking logic, similar to socket ref-tracking. It is thus
+impossible to reserve a record, but forget to submit (or discard) it.
+
+``bpf_ringbuf_query()`` helper allows to query various properties of ring
+buffer. Currently 4 are supported:
+
+- ``BPF_RB_AVAIL_DATA`` returns amount of unconsumed data in ring buffer;
+- ``BPF_RB_RING_SIZE`` returns the size of ring buffer;
+- ``BPF_RB_CONS_POS``/``BPF_RB_PROD_POS`` returns current logical possition
+ of consumer/producer, respectively.
+
+Returned values are momentarily snapshots of ring buffer state and could be
+off by the time helper returns, so this should be used only for
+debugging/reporting reasons or for implementing various heuristics, that take
+into account highly-changeable nature of some of those characteristics.
+
+One such heuristic might involve more fine-grained control over poll/epoll
+notifications about new data availability in ring buffer. Together with
+``BPF_RB_NO_WAKEUP``/``BPF_RB_FORCE_WAKEUP`` flags for output/commit/discard
+helpers, it allows BPF program a high degree of control and, e.g., more
+efficient batched notifications. Default self-balancing strategy, though,
+should be adequate for most applications and will work reliable and efficiently
+already.
+
+Design and Implementation
+-------------------------
+
+This reserve/commit schema allows a natural way for multiple producers, either
+on different CPUs or even on the same CPU/in the same BPF program, to reserve
+independent records and work with them without blocking other producers. This
+means that if BPF program was interruped by another BPF program sharing the
+same ring buffer, they will both get a record reserved (provided there is
+enough space left) and can work with it and submit it independently. This
+applies to NMI context as well, except that due to using a spinlock during
+reservation, in NMI context, ``bpf_ringbuf_reserve()`` might fail to get
+a lock, in which case reservation will fail even if ring buffer is not full.
+
+The ring buffer itself internally is implemented as a power-of-2 sized
+circular buffer, with two logical and ever-increasing counters (which might
+wrap around on 32-bit architectures, that's not a problem):
+
+- consumer counter shows up to which logical position consumer consumed the
+ data;
+- producer counter denotes amount of data reserved by all producers.
+
+Each time a record is reserved, producer that "owns" the record will
+successfully advance producer counter. At that point, data is still not yet
+ready to be consumed, though. Each record has 8 byte header, which contains the
+length of reserved record, as well as two extra bits: busy bit to denote that
+record is still being worked on, and discard bit, which might be set at commit
+time if record is discarded. In the latter case, consumer is supposed to skip
+the record and move on to the next one. Record header also encodes record's
+relative offset from the beginning of ring buffer data area (in pages). This
+allows ``bpf_ringbuf_commit()``/``bpf_ringbuf_discard()`` to accept only the
+pointer to the record itself, without requiring also the pointer to ring buffer
+itself. Ring buffer memory location will be restored from record metadata
+header. This significantly simplifies verifier, as well as improving API
+usability.
+
+Producer counter increments are serialized under spinlock, so there is
+a strict ordering between reservations. Commits, on the other hand, are
+completely lockless and independent. All records become available to consumer
+in the order of reservations, but only after all previous records where
+already committed. It is thus possible for slow producers to temporarily hold
+off submitted records, that were reserved later.
+
+Reservation/commit/consumer protocol is verified by litmus tests in
+Documentation/litmus_tests/bpf-rb/_.
+
+One interesting implementation bit, that significantly simplifies (and thus
+speeds up as well) implementation of both producers and consumers is how data
+area is mapped twice contiguously back-to-back in the virtual memory. This
+allows to not take any special measures for samples that have to wrap around
+at the end of the circular buffer data area, because the next page after the
+last data page would be first data page again, and thus the sample will still
+appear completely contiguous in virtual memory. See comment and a simple ASCII
+diagram showing this visually in ``bpf_ringbuf_area_alloc()``.
+
+Another feature that distinguishes BPF ringbuf from perf ring buffer is
+a self-pacing notifications of new data being availability.
+``bpf_ringbuf_commit()`` implementation will send a notification of new record
+being available after commit only if consumer has already caught up right up to
+the record being committed. If not, consumer still has to catch up and thus
+will see new data anyways without needing an extra poll notification.
+Benchmarks (see tools/testing/selftests/bpf/benchs/bench_ringbuf.c_) show that
+this allows to achieve a very high throughput without having to resort to
+tricks like "notify only every Nth sample", which are necessary with perf
+buffer. For extreme cases, when BPF program wants more manual control of
+notifications, commit/discard/output helpers accept ``BPF_RB_NO_WAKEUP`` and
+``BPF_RB_FORCE_WAKEUP`` flags, which give full control over notifications of
+data availability, but require extra caution and diligence in using this API.

-* Socionext AVE ethernet controller
-
-This describes the devicetree bindings for AVE ethernet controller
-implemented on Socionext UniPhier SoCs.
-
-Required properties:

-* Texas Instruments - dp83867 Giga bit ethernet phy
-
-Required properties:
- - reg - The ID number for the phy, usually a small integer
- - ti,rx-internal-delay - RGMII Receive Clock Delay - see dt-bindings/net/ti-dp83867.h
- for applicable values. Required only if interface type is
- PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_RXID
- - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
- for applicable values. Required only if interface type is
- PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID
-
-Note: If the interface type is PHY_INTERFACE_MODE_RGMII the TX/RX clock delays
- will be left at their default values, as set by the PHY's pin strapping.
- The default strapping will use a delay of 2.00 ns. Thus
- PHY_INTERFACE_MODE_RGMII, by default, does not behave as RGMII with no
- internal delay, but as PHY_INTERFACE_MODE_RGMII_ID. The device tree
- should use "rgmii-id" if internal delays are desired as this may be
- changed in future to cause "rgmii" mode to disable delays.
-
-Optional property:
- - ti,min-output-impedance - MAC Interface Impedance control to set
- the programmable output impedance to
- minimum value (35 ohms).
- - ti,max-output-impedance - MAC Interface Impedance control to set
- the programmable output impedance to
- maximum value (70 ohms).
- - ti,dp83867-rxctrl-strap-quirk - This denotes the fact that the
- board has RX_DV/RX_CTRL pin strapped in
- mode 1 or 2. To ensure PHY operation,
- there are specific actions that
- software needs to take when this pin is
- strapped in these modes. See data manual
- for details.
- - ti,clk-output-sel - Muxing option for CLK_OUT pin. See dt-bindings/net/ti-dp83867.h
- for applicable values. The CLK_OUT pin can also
- be disabled by this property. When omitted, the
- PHY's default will be left as is.
- - ti,sgmii-ref-clock-output-enable - This denotes which
- SGMII configuration is used (4 or 6-wire modes).
- Some MACs work with differential SGMII clock.
- See data manual for details.
-
- - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
- for applicable values (deprecated)
-
- -tx-fifo-depth - As defined in the ethernet-controller.yaml. Values for

- -rx-fifo-depth - As defined in the ethernet-controller.yaml. Values for
- the depth can be found in dt-bindings/net/ti-dp83867.h
-
-Note: ti,min-output-impedance and ti,max-output-impedance are mutually

+ The DP83867 device is a robust, low power, fully featured Physical Layer
+ transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX
+ and 1000BASE-T Ethernet protocols.
+
+ The DP83867 is designed for easy implementation of 10/100/1000 Mbps Ethernet
+ LANs. It interfaces directly to twisted pair media via an external
+ transformer. This device interfaces directly to the MAC layer through the
+ IEEE 802.3 Standard Media Independent Interface (MII), the IEEE 802.3 Gigabit
+ Media Independent Interface (GMII) or Reduced GMII (RGMII).

+title: The TI AM654x/J721E Common Platform Time Sync (CPTS) module Device Tree Bindings
+
+maintainers:

+ - Sekhar Nori <nsekhar@ti.com>
+
+description: |+
+ The TI AM654x/J721E CPTS module is used to facilitate host control of time
+ sync operations.
+ Main features of CPTS module are
+ - selection of multiple external clock sources
+ - Software control of time sync events via interrupt or polling
+ - 64-bit timestamp mode in ns with PPM and nudge adjustment.
+ - hardware timestamp push inputs (HWx_TS_PUSH)
+ - timestamp counter compare output (TS_COMP)
+ - timestamp counter bit output (TS_SYNC)
+ - periodic Generator function outputs (TS_GENFx)
+ - Ethernet Enhanced Scheduled Traffic Operations (CPTS_ESTFn) (TSN)
+ - external hardware timestamp push inputs (HWx_TS_PUSH) timestamping
+
+ Depending on integration it enables compliance with the IEEE 1588-2008
+ standard for a precision clock synchronization protocol, Ethernet Enhanced
+ Scheduled Traffic Operations (CPTS_ESTFn) and PCIe Subsystem Precision Time
+ Measurement (PTM).
+
+ TI AM654x/J721E SoCs has several similar CPTS modules integrated into the
+ different parts of the system which could be synchronized with each other
+ - Main CPTS
+ - MCU CPSW CPTS with IEEE 1588-2008 support
+ - PCIe subsystem CPTS for PTM support
+
+ Depending on CPTS module integration and when CPTS is integral part of
+ another module (MCU CPSW for example) "compatible" and "reg" can
+ be omitted - parent module is fully responsible for CPTS enabling and
+ configuration.
