- *
- * The TILE-Gx mPIPE&tm; shim provides Ethernet connectivity, packet
- * classification, and packet load balancing services. The
- * gxio_mpipe_ API, declared in <gxio/mpipe.h>, allows applications to
- * allocate mPIPE IO channels, configure packet distribution
- * parameters, and send and receive Ethernet packets. The API is
- * designed to be a minimal wrapper around the mPIPE hardware, making
- * system calls only where necessary to preserve inter-process
- * protection guarantees.
- *
- * The APIs described below allow the programmer to allocate and
- * configure mPIPE resources. As described below, the mPIPE is a
- * single shared hardware device that provides partitionable resources
- * that are shared between all applications in the system. The
- * gxio_mpipe_ API allows userspace code to make resource request
- * calls to the hypervisor, which in turns keeps track of the
- * resources in use by all applications, maintains protection
- * guarantees, and resets resources upon application shutdown.
- *
- * We strongly recommend reading the mPIPE section of the IO Device
- * Guide (UG404) before working with this API. Most functions in the
- * gxio_mpipe_ API are directly analogous to hardware interfaces and
- * the documentation assumes that the reader understands those
- * hardware interfaces.
- *
- * @section mpipe__ingress mPIPE Ingress Hardware Resources
- *
- * The mPIPE ingress hardware provides extensive hardware offload for
- * tasks like packet header parsing, load balancing, and memory
- * management. This section provides a brief introduction to the
- * hardware components and the gxio_mpipe_ calls used to manage them;
- * see the IO Device Guide for a much more detailed description of the
- * mPIPE's capabilities.
- *
- * When a packet arrives at one of the mPIPE's Ethernet MACs, it is
- * assigned a channel number indicating which MAC received it. It
- * then proceeds through the following hardware pipeline:
- *
- * @subsection mpipe__classification Classification
- *
- * A set of classification processors run header parsing code on each
- * incoming packet, extracting information including the destination
- * MAC address, VLAN, Ethernet type, and five-tuple hash. Some of
- * this information is then used to choose which buffer stack will be
- * used to hold the packet, and which bucket will be used by the load
- * balancer to determine which application will receive the packet.
- *
- * The rules by which the buffer stack and bucket are chosen can be
- * configured via the @ref gxio_mpipe_classifier API. A given app can
- * specify multiple rules, each one specifying a bucket range, and a
- * set of buffer stacks, to be used for packets matching the rule.
- * Each rule can optionally specify a restricted set of channels,
- * VLANs, and/or dMACs, in which it is interested. By default, a
- * given rule starts out matching all channels associated with the
- * mPIPE context's set of open links; all VLANs; and all dMACs.
- * Subsequent restrictions can then be added.
- *
- * @subsection mpipe__load_balancing Load Balancing
- *
- * The mPIPE load balancer is responsible for choosing the NotifRing
- * to which the packet will be delivered. This decision is based on
- * the bucket number indicated by the classification program. In
- * general, the bucket number is based on some number of low bits of
- * the packet's flow hash (applications that aren't interested in flow
- * hashing use a single bucket). Each load balancer bucket keeps a
- * record of the NotifRing to which packets directed to that bucket
- * are currently being delivered. Based on the bucket's load
- * balancing mode (@ref gxio_mpipe_bucket_mode_t), the load balancer
- * either forwards the packet to the previously assigned NotifRing or
- * decides to choose a new NotifRing. If a new NotifRing is required,
- * the load balancer chooses the least loaded ring in the NotifGroup
- * associated with the bucket.
- *
- * The load balancer is a shared resource. Each application needs to
- * explicitly allocate NotifRings, NotifGroups, and buckets, using
- * gxio_mpipe_alloc_notif_rings(), gxio_mpipe_alloc_notif_groups(),
- * and gxio_mpipe_alloc_buckets(). Then the application needs to
- * configure them using gxio_mpipe_init_notif_ring() and
- * gxio_mpipe_init_notif_group_and_buckets().
- *
- * @subsection mpipe__buffers Buffer Selection and Packet Delivery
- *
- * Once the load balancer has chosen the destination NotifRing, the
- * mPIPE DMA engine pops at least one buffer off of the 'buffer stack'
- * chosen by the classification program and DMAs the packet data into
- * that buffer. Each buffer stack provides a hardware-accelerated
- * stack of data buffers with the same size. If the packet data is
- * larger than the buffers provided by the chosen buffer stack, the
- * mPIPE hardware pops off multiple buffers and chains the packet data
- * through a multi-buffer linked list. Once the packet data is
- * delivered to the buffer(s), the mPIPE hardware writes the
- * ::gxio_mpipe_idesc_t metadata object (calculated by the classifier)
- * into the NotifRing and increments the number of packets delivered
- * to that ring.
- *
- * Applications can push buffers onto a buffer stack by calling
- * gxio_mpipe_push_buffer() or by egressing a packet with the
- * ::gxio_mpipe_edesc_t::hwb bit set, indicating that the egressed
- * buffers should be returned to the stack.
- *
- * Applications can allocate and initialize buffer stacks with the
- * gxio_mpipe_alloc_buffer_stacks() and gxio_mpipe_init_buffer_stack()
- * APIs.
- *
- * The application must also register the memory pages that will hold
- * packets. This requires calling gxio_mpipe_register_page() for each
- * memory page that will hold packets allocated by the application for
- * a given buffer stack. Since each buffer stack is limited to 16
- * registered pages, it may be necessary to use huge pages, or even
- * extremely huge pages, to hold all the buffers.
- *
- * @subsection mpipe__iqueue NotifRings
- *
- * Each NotifRing is a region of shared memory, allocated by the
- * application, to which the mPIPE delivers packet descriptors
- * (::gxio_mpipe_idesc_t). The application can allocate them via
- * gxio_mpipe_alloc_notif_rings(). The application can then either
- * explicitly initialize them with gxio_mpipe_init_notif_ring() and
- * then read from them manually, or can make use of the convenience
- * wrappers provided by @ref gxio_mpipe_wrappers.
- *
- * @section mpipe__egress mPIPE Egress Hardware
- *
- * Applications use eDMA rings to queue packets for egress. The
- * application can allocate them via gxio_mpipe_alloc_edma_rings().
- * The application can then either explicitly initialize them with
- * gxio_mpipe_init_edma_ring() and then write to them manually, or
- * can make use of the convenience wrappers provided by
- * @ref gxio_mpipe_wrappers.
- *
- * @section gxio__shortcomings Plans for Future API Revisions
- *
- * The API defined here is only an initial version of the mPIPE API.
- * Future plans include:
- *
- * - Higher level wrapper functions to provide common initialization
- * patterns. This should help users start writing mPIPE programs
- * without having to learn the details of the hardware.
- *
- * - Support for reset and deallocation of resources, including
- * cleanup upon application shutdown.
- *
- * - Support for calling these APIs in the BME.
- *
- * - Support for IO interrupts.
- *
- * - Clearer definitions of thread safety guarantees.
- *
- * @section gxio__mpipe_examples Examples
- *
- * See the following mPIPE example programs for more information about
- * allocating mPIPE resources and using them in real applications:
- *
- * - @ref mpipe/ingress/app.c : Receiving packets.
- *
- * - @ref mpipe/forward/app.c : Forwarding packets.
- *
- * Note that there are several more examples.

- * Classifier Program *
- ******************************************************************/
-
-/*
- *
- * Functions for loading or configuring the mPIPE classifier program.
- *
- * The mPIPE classification processors all run a special "classifier"
- * program which, for each incoming packet, parses the packet headers,
- * encodes some packet metadata in the "idesc", and either drops the
- * packet, or picks a notif ring to handle the packet, and a buffer
- * stack to contain the packet, usually based on the channel, VLAN,
- * dMAC, flow hash, and packet size, under the guidance of the "rules"
- * API described below.
- *
- * @section gxio_mpipe_classifier_default Default Classifier
- *
- * The MDE provides a simple "default" classifier program. It is
- * shipped as source in "$TILERA_ROOT/src/sys/mpipe/classifier.c",
- * which serves as its official documentation. It is shipped as a
- * binary program in "$TILERA_ROOT/tile/boot/classifier", which is
- * automatically included in bootroms created by "tile-monitor", and
- * is automatically loaded by the hypervisor at boot time.
- *
- * The L2 analysis handles LLC packets, SNAP packets, and "VLAN
- * wrappers" (keeping the outer VLAN).
- *
- * The L3 analysis handles IPv4 and IPv6, dropping packets with bad
- * IPv4 header checksums, requesting computation of a TCP/UDP checksum
- * if appropriate, and hashing the dest and src IP addresses, plus the
- * ports for TCP/UDP packets, into the flow hash. No special analysis
- * is done for "fragmented" packets or "tunneling" protocols. Thus,
- * the first fragment of a fragmented TCP/UDP packet is hashed using
- * src/dest IP address and ports and all subsequent fragments are only
- * hashed according to src/dest IP address.
- *
- * The L3 analysis handles other packets too, hashing the dMAC
- * smac into a flow hash.
- *
- * The channel, VLAN, and dMAC used to pick a "rule" (see the
- * "rules" APIs below), which in turn is used to pick a buffer stack
- * (based on the packet size) and a bucket (based on the flow hash).
- *
- * To receive traffic matching a particular (channel/VLAN/dMAC
- * pattern, an application should allocate its own buffer stacks and
- * load balancer buckets, and map traffic to those stacks and buckets,
- * as decribed by the "rules" API below.
- *
- * Various packet metadata is encoded in the idesc. The flow hash is
- * four bytes at 0x0C. The VLAN is two bytes at 0x10. The ethtype is
- * two bytes at 0x12. The l3 start is one byte at 0x14. The l4 start
- * is one byte at 0x15 for IPv4 and IPv6 packets, and otherwise zero.
- * The protocol is one byte at 0x16 for IPv4 and IPv6 packets, and
- * otherwise zero.
- *
- * @section gxio_mpipe_classifier_custom Custom Classifiers.
- *
- * A custom classifier may be created using "tile-mpipe-cc" with a
- * customized version of the default classifier sources.
- *
- * The custom classifier may be included in bootroms using the
- * "--classifier" option to "tile-monitor", or loaded dynamically
- * using gxio_mpipe_classifier_load_from_file().
- *
- * Be aware that "extreme" customizations may break the assumptions of

- * returns success when the state object has been initialized and the
- * hardware configured to deliver packets to the specified ring
- * buffer. Similarly, gxio_mpipe_equeue_init() takes a
- * ::gxio_mpipe_equeue_t state object, a ring number from
- * gxio_mpipe_alloc_edma_rings(), and a shared memory buffer.
- *
- * @section gxio_mpipe_iqueue Working with Ingress Queues
- *
- * Once initialized, the gxio_mpipe_iqueue_t API provides two flows
- * for getting the ::gxio_mpipe_idesc_t packet descriptor associated
- * with incoming packets. The simplest is to call
- * gxio_mpipe_iqueue_get() or gxio_mpipe_iqueue_try_get(). These
- * functions copy the oldest packet descriptor out of the NotifRing and
- * into a descriptor provided by the caller. They also immediately
- * inform the hardware that a descriptor has been processed.
- *
- * For applications with stringent performance requirements, higher
- * efficiency can be achieved by avoiding the packet descriptor copy
- * and processing multiple descriptors at once. The
- * gxio_mpipe_iqueue_peek() and gxio_mpipe_iqueue_try_peek() functions
- * allow such optimizations. These functions provide a pointer to the
- * next valid ingress descriptor in the NotifRing's shared memory ring
- * buffer, and a count of how many contiguous descriptors are ready to
- * be processed. The application can then process any number of those
- * descriptors in place, calling gxio_mpipe_iqueue_consume() to inform
- * the hardware after each one has been processed.
- *
- * @section gxio_mpipe_equeue Working with Egress Queues
- *
- * Similarly, the egress queue API provides a high-performance
- * interface plus a simple wrapper for use in posting
- * ::gxio_mpipe_edesc_t egress packet descriptors. The simple
- * version, gxio_mpipe_equeue_put(), allows the programmer to wait for
- * an eDMA ring slot to become available and write a single descriptor
- * into the ring.
- *
- * Alternatively, you can reserve slots in the eDMA ring using
- * gxio_mpipe_equeue_reserve() or gxio_mpipe_equeue_try_reserve(), and
- * then fill in each slot using gxio_mpipe_equeue_put_at(). This
- * capability can be used to amortize the cost of reserving slots
- * across several packets. It also allows gather operations to be
- * performed on a shared equeue, by ensuring that the edescs for all
- * the fragments are all contiguous in the eDMA ring.
- *
- * The gxio_mpipe_equeue_reserve() and gxio_mpipe_equeue_try_reserve()
- * functions return a 63-bit "completion slot", which is actually a
- * sequence number, the low bits of which indicate the ring buffer
- * index and the high bits the number of times the application has
- * gone around the egress ring buffer. The extra bits allow an
- * application to check for egress completion by calling
- * gxio_mpipe_equeue_is_complete() to see whether a particular 'slot'
- * number has finished. Given the maximum packet rates of the Gx
- * processor, the 63-bit slot number will never wrap.
- *
- * In practice, most applications use the ::gxio_mpipe_edesc_t::hwb
- * bit to indicate that the buffers containing egress packet data
- * should be pushed onto a buffer stack when egress is complete. Such
- * applications generally do not need to know when an egress operation
- * completes (since there is no need to free a buffer post-egress),
- * and thus can use the optimized gxio_mpipe_equeue_reserve_fast() or
- * gxio_mpipe_equeue_try_reserve_fast() functions, which return a 24
- * bit "slot", instead of a 63-bit "completion slot".
- *
- * Once a slot has been "reserved", it MUST be filled. If the
- * application reserves a slot and then decides that it does not
- * actually need it, it can set the ::gxio_mpipe_edesc_t::ns (no send)
- * bit on the descriptor passed to gxio_mpipe_equeue_put_at() to
- * indicate that no data should be sent. This technique can also be
- * used to drop an incoming packet, instead of forwarding it, since
- * any buffer will still be pushed onto the buffer stack when the
- * egress descriptor is processed.

- * Link Management *
- ******************************************************************/
-
-/*
- *
- * Functions for manipulating and sensing the state and configuration
- * of physical network links.
- *
- * @section gxio_mpipe_link_perm Link Permissions
- *
- * Opening a link (with gxio_mpipe_link_open()) requests a set of link
- * permissions, which control what may be done with the link, and potentially
- * what permissions may be granted to other processes.
- *
- * Data permission allows the process to receive packets from the link by
- * specifying the link's channel number in mPIPE packet distribution rules,
- * and to send packets to the link by using the link's channel number as
- * the target for an eDMA ring.
- *
- * Stats permission allows the process to retrieve link attributes (such as
- * the speeds it is capable of running at, or whether it is currently up), and
- * to read and write certain statistics-related registers in the link's MAC.
- *
- * Control permission allows the process to retrieve and modify link attributes
- * (so that it may, for example, bring the link up and take it down), and
- * read and write many registers in the link's MAC and PHY.
- *
- * Any permission may be requested as shared, which allows other processes
- * to also request shared permission, or exclusive, which prevents other
- * processes from requesting it. In keeping with GXIO's typical usage in
- * an embedded environment, the defaults for all permissions are shared.
- *
- * Permissions are granted on a first-come, first-served basis, so if two
- * applications request an exclusive permission on the same link, the one
- * to run first will win. Note, however, that some system components, like
- * the kernel Ethernet driver, may get an opportunity to open links before
- * any applications run.
- *
- * @section gxio_mpipe_link_names Link Names
- *
- * Link names are of the form gbe<em>number</em> (for Gigabit Ethernet),
- * xgbe<em>number</em> (for 10 Gigabit Ethernet), loop<em>number</em> (for
- * internal mPIPE loopback), or ilk<em>number</em>/<em>channel</em>
- * (for Interlaken links); for instance, gbe0, xgbe1, loop3, and
- * ilk0/12 are all possible link names. The correspondence between
- * the link name and an mPIPE instance number or mPIPE channel number is
- * system-dependent; all links will not exist on all systems, and the set
- * of numbers used for a particular link type may not start at zero and may
- * not be contiguous. Use gxio_mpipe_link_enumerate() to retrieve the set of
- * links which exist on a system, and always use gxio_mpipe_link_instance()
- * to determine which mPIPE controls a particular link.
- *
- * Note that in some cases, links may share hardware, such as PHYs, or

- * opened at a time. This is especially common with xgbe and gbe ports,
- * since each xgbe port uses 4 SERDES lanes, each of which may also be
- * configured as one gbe port.
- *
- * @section gxio_mpipe_link_states Link States
- *
- * The mPIPE link management model revolves around three different states,
- * which are maintained for each link:
- *
- * 1. The <em>current</em> link state: is the link up now, and if so, at
- * what speed?
- *
- * 2. The <em>desired</em> link state: what do we want the link state to be?
- * The system is always working to make this state the current state;
- * thus, if the desired state is up, and the link is down, we'll be
- * constantly trying to bring it up, automatically.
- *
- * 3. The <em>possible</em> link state: what speeds are valid for this
- * particular link? Or, in other words, what are the capabilities of
- * the link hardware?
- *
- * These link states are not, strictly speaking, related to application
- * state; they may be manipulated at any time, whether or not the link
- * is currently being used for data transfer. However, for convenience,
- * gxio_mpipe_link_open() and gxio_mpipe_link_close() (or application exit)
- * can affect the link state. These implicit link management operations
- * may be modified or disabled by the use of link open flags.
- *
- * From an application, you can use gxio_mpipe_link_get_attr()
- * and gxio_mpipe_link_set_attr() to manipulate the link states.
- * gxio_mpipe_link_get_attr() with ::GXIO_MPIPE_LINK_POSSIBLE_STATE
- * gets you the possible link state. gxio_mpipe_link_get_attr() with
- * ::GXIO_MPIPE_LINK_CURRENT_STATE gets you the current link state.
- * Finally, gxio_mpipe_link_set_attr() and gxio_mpipe_link_get_attr()
- * with ::GXIO_MPIPE_LINK_DESIRED_STATE allow you to modify or retrieve
- * the desired link state.
- *
- * If you want to manage a link from a part of your application which isn't
- * involved in packet processing, you can use the ::GXIO_MPIPE_LINK_NO_DATA
- * flags on a gxio_mpipe_link_open() call. This opens the link, but does
- * not request data permission, so it does not conflict with any exclusive
- * permissions which may be held by other processes. You can then can use
- * gxio_mpipe_link_get_attr() and gxio_mpipe_link_set_attr() on this link
- * object to bring up or take down the link.
- *
- * Some links support link state bits which support various loopback
- * modes. ::GXIO_MPIPE_LINK_LOOP_MAC tests datapaths within the Tile
- * Processor itself; ::GXIO_MPIPE_LINK_LOOP_PHY tests the datapath between
- * the Tile Processor and the external physical layer interface chip; and
- * ::GXIO_MPIPE_LINK_LOOP_EXT tests the entire network datapath with the
- * aid of an external loopback connector. In addition to enabling hardware
- * testing, such configuration can be useful for software testing, as well.
- *
- * When LOOP_MAC or LOOP_PHY is enabled, packets transmitted on a channel
- * will be received by that channel, instead of being emitted on the
- * physical link, and packets received on the physical link will be ignored.
- * Other than that, all standard GXIO operations work as you might expect.
- * Note that loopback operation requires that the link be brought up using
- * one or more of the GXIO_MPIPE_LINK_SPEED_xxx link state bits.
- *
- * Those familiar with previous versions of the MDE on TILEPro hardware
- * will notice significant similarities between the NetIO link management
- * model and the mPIPE link management model. However, the NetIO model
- * was developed in stages, and some of its features -- for instance,
- * the default setting of certain flags -- were shaped by the need to be
- * compatible with previous versions of NetIO. Since the features provided
- * by the mPIPE hardware and the mPIPE GXIO library are significantly
- * different than those provided by NetIO, in some cases, we have made
- * different choices in the mPIPE link management API. Thus, please read
- * this documentation carefully before assuming that mPIPE link management
- * operations are exactly equivalent to their NetIO counterparts.

-/*
- *
- * An API for allocating, configuring, and manipulating TRIO hardware
- * resources
- */
-
-/*
- *
- * The TILE-Gx TRIO shim provides connections to external devices via
- * PCIe or other transaction IO standards. The gxio_trio_ API,
- * declared in <gxio/trio.h>, allows applications to allocate and
- * configure TRIO IO resources like DMA command rings, memory map
- * windows, and device interrupts. The following sections introduce
- * the various components of the API. We strongly recommend reading
- * the TRIO section of the IO Device Guide (UG404) before working with
- * this API.
- *
- * @section trio__ingress TRIO Ingress Hardware Resources
- *
- * The TRIO ingress hardware is responsible for examining incoming
- * PCIe or StreamIO packets and choosing a processing mechanism based
- * on the packets' bus address. The gxio_trio_ API can be used to
- * configure different handlers for different ranges of bus address
- * space. The user can configure "mapped memory" and "scatter queue"
- * regions to match incoming packets within 4kB-aligned ranges of bus
- * addresses. Each range specifies a different set of mapping
- * parameters to be applied when handling the ingress packet. The
- * following sections describe how to work with MapMem and scatter
- * queue regions.
- *
- * @subsection trio__mapmem TRIO MapMem Regions
- *
- * TRIO mapped memory (or MapMem) regions allow the user to map
- * incoming read and write requests directly to the application's
- * memory space. MapMem regions are allocated via
- * gxio_trio_alloc_memory_maps(). Given an integer MapMem number,
- * applications can use gxio_trio_init_memory_map() to specify the
- * range of bus addresses that will match the region and the range of
- * virtual addresses to which those packets will be applied.
- *
- * As with many other gxio APIs, the programmer must be sure to
- * register memory pages that will be used with MapMem regions. Pages
- * can be registered with TRIO by allocating an ASID (address space
- * identifier) and then using gxio_trio_register_page() to register up to
- * 16 pages with the hardware. The initialization functions for
- * resources that require registered memory (MapMem, scatter queues,
- * push DMA, and pull DMA) then take an 'asid' parameter in order to
- * configure which set of registered pages is used by each resource.
- *
- * @subsection trio__scatter_queue TRIO Scatter Queues
- *
- * The TRIO shim's scatter queue regions allow users to dynamically
- * map buffers from a large address space into a small range of bus
- * addresses. This is particularly helpful for PCIe endpoint devices,
- * where the host generally limits the size of BARs to tens of
- * megabytes.
- *
- * Each scatter queue consists of a memory map region, a queue of
- * tile-side buffer VAs to be mapped to that region, and a bus-mapped
- * "doorbell" register that the remote endpoint can write to trigger a
- * dequeue of the current buffer VA, thus swapping in a new buffer.
- * The VAs pushed onto a scatter queue must be 4kB aligned, so
- * applications may need to use higher-level protocols to inform
- * remote entities that they should apply some additional, sub-4kB
- * offset when reading or writing the scatter queue region. For more
- * information, see the IO Device Guide (UG404).
- *
- * @section trio__egress TRIO Egress Hardware Resources
- *
- * The TRIO shim supports two mechanisms for egress packet generation:
- * programmed IO (PIO) and push/pull DMA. PIO allows applications to
- * create MMIO mappings for PCIe or StreamIO address space, such that
- * the application can generate word-sized read or write transactions
- * by issuing load or store instructions. Push and pull DMA are tuned
- * for larger transactions; they use specialized hardware engines to
- * transfer large blocks of data at line rate.
- *
- * @subsection trio__pio TRIO Programmed IO
- *
- * Programmed IO allows applications to create MMIO mappings for PCIe
- * or StreamIO address space. The hardware PIO regions support access
- * to PCIe configuration, IO, and memory space, but the gxio_trio API
- * only supports memory space accesses. PIO regions are allocated
- * with gxio_trio_alloc_pio_regions() and initialized via
- * gxio_trio_init_pio_region(). Once a region is bound to a range of
- * bus address via the initialization function, the application can
- * use gxio_trio_map_pio_region() to create MMIO mappings from its VA
- * space onto the range of bus addresses supported by the PIO region.
- *
- * @subsection trio_dma TRIO Push and Pull DMA
- *
- * The TRIO push and pull DMA engines allow users to copy blocks of
- * data between application memory and the bus. Push DMA generates
- * write packets that copy from application memory to the bus and pull
- * DMA generates read packets that copy from the bus into application
- * memory. The DMA engines are managed via an API that is very
- * similar to the mPIPE eDMA interface. For a detailed explanation of
- * the eDMA queue API, see @ref gxio_mpipe_wrappers.
- *
- * Push and pull DMA queues are allocated via
- * gxio_trio_alloc_push_dma_ring() / gxio_trio_alloc_pull_dma_ring().
- * Once allocated, users generally use a ::gxio_trio_dma_queue_t
- * object to manage the queue, providing easy wrappers for reserving
- * command slots in the DMA command ring, filling those slots, and
- * waiting for commands to complete. DMA queues can be initialized
- * via gxio_trio_init_push_dma_queue() or
- * gxio_trio_init_pull_dma_queue().
- *
- * See @ref trio/push_dma/app.c for an example of how to use push DMA.
- *
- * @section trio_shortcomings Plans for Future API Revisions
- *
- * The simulation framework is incomplete. Future features include:
- *
- * - Support for reset and deallocation of resources.
- *
- * - Support for pull DMA.
- *
- * - Support for interrupt regions and user-space interrupt delivery.
- *
- * - Support for getting BAR mappings and reserving regions of BAR
- * address space.

-/** A queue of packets.
- *
- * This structure partially defines a queue of packets waiting to be
- * processed. The queue as a whole is written to by an interrupt handler and

- * interrupt handler. The other part of the queue state, the read offset, is
- * kept in user space, not in hypervisor space, so it is in a separate data
- * structure.
- *
- * The read offset (__packet_receive_read in the user part of the queue
- * structure) points to the next packet to be read. When the read offset is
- * equal to the write offset, the queue is empty; therefore the queue must
- * contain one more slot than the required maximum queue size.
- *
- * Here's an example of all 3 state variables and what they mean. All
- * pointers move left to right.

-/** A queue of buffers.
- *
- * This structure partially defines a queue of empty buffers which have been
- * obtained via requests to the IPP. (The elements of the queue are packet
- * handles, which are transformed into a full netio_pkt_t when the buffer is
- * retrieved.) The queue as a whole is written to by an interrupt handler and
- * read by non-interrupt code; this data structure is what's touched by the
- * interrupt handler. The other parts of the queue state, the read offset and
- * requested write offset, are kept in user space, not in hypervisor space, so
- * they are in a separate data structure.
- *
- * The read offset (__buffer_read in the user part of the queue structure)
- * points to the next buffer to be read. When the read offset is equal to the
- * write offset, the queue is empty; therefore the queue must contain one more
- * slot than the required maximum queue size.
- *
- * The requested write offset (__buffer_requested_write in the user part of
- * the queue structure) points to the slot which will hold the next buffer we
- * request from the IPP, once we get around to sending such a request. When
- * the requested write offset is equal to the write offset, no requests for
- * new buffers are outstanding; when the requested write offset is one greater
- * than the read offset, no more requests may be sent.
- *
- * Note that, unlike the packet_queue, the buffer_queue places incoming
- * buffers at decreasing addresses. This makes the check for "is it time to
- * wrap the buffer pointer" cheaper in the assembly code which receives new
- * buffers, and means that the value which defines the queue size,
- * __last_buffer, is different than in the packet queue. Also, the offset
- * used in the packet_queue is already scaled by the size of a packet; here we
- * use unscaled slot indices for the offsets. (These differences are
- * historical, and in the future it's possible that the packet_queue will look
- * more like this queue.)
- *
- * @code
- * Here's an example of all 4 state variables and what they mean. Remember:
- * all pointers move right to left.

- * 0 1 2 3 4 5 6 7 8 9

- *
- * This queue has 10 slots, and thus can hold 9 buffers (_last_buffer = 9).
- * The read pointer is at 2, and the write pointer is at 6; thus, there are
- * valid, unread buffers in slots 2, 1, 0, 9, 8, and 7. The requested write
- * pointer is at 4; thus, requests have been made to the IPP for buffers which
- * will be placed in slots 6 and 5 when they arrive. Finally, the remaining

-/** Dispatch the next interrupt from the client downcall mechanism.

- * The hypervisor uses downcalls to notify the client of asynchronous

- * messages). Some are regular interrupts which initially occur in
- * the hypervisor, and are normally handled directly by the client;
- * when these occur in a client's interrupt critical section, they must
- * be delivered through the downcall mechanism.
- *
- * A downcall is initially delivered to the client as an INTCTRL_CL
- * interrupt, where CL is the client's PL. Upon entry to the INTCTRL_CL
- * vector, the client must immediately invoke the hv_downcall_dispatch
- * service. This service will not return; instead it will cause one of
- * the client's actual downcall-handling interrupt vectors to be entered.
- * The EX_CONTEXT registers in the client will be set so that when the
- * client irets, it will return to the code which was interrupted by the
- * INTCTRL_CL interrupt.
- *
- * Under some circumstances, the firing of INTCTRL_CL can race with
- * the lowering of a device interrupt. In such a case, the
- * hv_downcall_dispatch service may issue an iret instruction instead
- * of entering one of the client's actual downcall-handling interrupt
- * vectors. This will return execution to the location that was
- * interrupted by INTCTRL_CL.
- *
- * Any saving of registers should be done by the actual handling
- * vectors; no registers should be changed by the INTCTRL_CL handler.
- * In particular, the client should not use a jal instruction to invoke
- * the hv_downcall_dispatch service, as that would overwrite the client's
- * lr register. Note that the hv_downcall_dispatch service may overwrite
- * one or more of the client's system save registers.
- *
- * The client must not modify the INTCTRL_CL_STATUS SPR. The hypervisor
- * will set this register to cause a downcall to happen, and will clear
- * it when no further downcalls are pending.
- *
- * When a downcall vector is entered, the INTCTRL_CL interrupt will be
- * masked. When the client is done processing a downcall, and is ready
- * to accept another, it must unmask this interrupt; if more downcalls
- * are pending, this will cause the INTCTRL_CL vector to be reentered.
- * Currently the following interrupt vectors can be entered through a
- * downcall:
- *
- * INT_MESSAGE_RCV_DWNCL (hypervisor message available)
- * INT_DEV_INTR_DWNCL (device interrupt)

-/**
- *
- * Error codes and struct definitions for the IO RPC library.
- *
- * The hypervisor's IO RPC component provides a convenient way for
- * driver authors to proxy system calls between user space, linux, and
- * the hypervisor driver. The core of the system is a set of Python
- * files that take ".idl" files as input and generates the following
- * source code:
- *
- * - _rpc_call() routines for use in userspace IO libraries. These
- * routines take an argument list specified in the .idl file, pack the
- * arguments in to a buffer, and read or write that buffer via the
- * Linux iorpc driver.
- *
- * - dispatch_read() and dispatch_write() routines that hypervisor
- * drivers can use to implement most of their dev_pread() and
- * dev_pwrite() methods. These routines decode the incoming parameter
- * blob, permission check and translate parameters where appropriate,
- * and then invoke a callback routine for whichever RPC call has
- * arrived. The driver simply implements the set of callback
- * routines.
- *
- * The IO RPC system also includes the Linux 'iorpc' driver, which
- * proxies calls between the userspace library and the hypervisor
- * driver. The Linux driver is almost entirely device agnostic; it
- * watches for special flags indicating cases where a memory buffer
- * address might need to be translated, etc. As a result, driver
- * writers can avoid many of the problem cases related to registering
- * hardware resources like memory pages or interrupts. However, the
- * drivers must be careful to obey the conventions documented below in
- * order to work properly with the generic Linux iorpc driver.
- *
- * @section iorpc_domains Service Domains
- *
- * All iorpc-based drivers must support a notion of service domains.
- * A service domain is basically an application context - state
- * indicating resources that are allocated to that particular app
- * which it may access and (perhaps) other applications may not
- * access. Drivers can support any number of service domains they
- * choose. In some cases the design is limited by a number of service
- * domains supported by the IO hardware; in other cases the service
- * domains are a purely software concept and the driver chooses a
- * maximum number of domains based on how much state memory it is
- * willing to preallocate.
- *
- * For example, the mPIPE driver only supports as many service domains
- * as are supported by the mPIPE hardware. This limitation is
- * required because the hardware implements its own MMIO protection
- * scheme to allow large MMIO mappings while still protecting small
- * register ranges within the page that should only be accessed by the
- * hypervisor.
- *
- * In contrast, drivers with no hardware service domain limitations
- * (for instance the TRIO shim) can implement an arbitrary number of
- * service domains. In these cases, each service domain is limited to
- * a carefully restricted set of legal MMIO addresses if necessary to
- * keep one application from corrupting another application's state.
- *
- * @section iorpc_conventions System Call Conventions
- *
- * The driver's open routine is responsible for allocating a new
- * service domain for each hv_dev_open() call. By convention, the
- * return value from open() should be the service domain number on
- * success, or GXIO_ERR_NO_SVC_DOM if no more service domains are
- * available.
- *
- * The implementations of hv_dev_pread() and hv_dev_pwrite() are
- * responsible for validating the devhdl value passed up by the
- * client. Since the device handle returned by hv_dev_open() should
- * embed the positive service domain number, drivers should make sure
- * that DRV_HDL2BITS(devhdl) is a legal service domain. If the client
- * passes an illegal service domain number, the routine should return
- * GXIO_ERR_INVAL_SVC_DOM. Once the service domain number has been
- * validated, the driver can copy to/from the client buffer and call
- * the dispatch_read() or dispatch_write() methods created by the RPC
- * generator.
- *
- * The hv_dev_close() implementation should reset all service domain
- * state and put the service domain back on a free list for
- * reallocation by a future application. In most cases, this will
- * require executing a hardware reset or drain flow and denying any
- * MMIO regions that were created for the service domain.
- *
- * @section iorpc_data Special Data Types
- *
- * The .idl file syntax allows the creation of syscalls with special
- * parameters that require permission checks or translations as part
- * of the system call path. Because of limitations in the code
- * generator, APIs are generally limited to just one of these special
- * parameters per system call, and they are sometimes required to be
- * the first or last parameter to the call. Special parameters
- * include:
- *
- * @subsection iorpc_mem_buffer MEM_BUFFER
- *
- * The MEM_BUFFER() datatype allows user space to "register" memory
- * buffers with a device. Registering memory accomplishes two tasks:
- * Linux keeps track of all buffers that might be modified by a
- * hardware device, and the hardware device drivers bind registered
- * buffers to particular hardware resources like ingress NotifRings.
- * The MEM_BUFFER() idl syntax can take extra flags like ALIGN_64KB,
- * ALIGN_SELF_SIZE, and FLAGS indicating that memory buffers must have
- * certain alignment or that the user should be able to pass a "memory
- * flags" word specifying attributes like nt_hint or IO cache pinning.
- * The parser will accept multiple MEM_BUFFER() flags.
- *
- * Implementations must obey the following conventions when
- * registering memory buffers via the iorpc flow. These rules are a
- * result of the Linux driver implementation, which needs to keep
- * track of how many times a particular page has been registered with
- * the hardware so that it can release the page when all those
- * registrations are cleared.
- *
- * - Memory registrations that refer to a resource which has already
- * been bound must return GXIO_ERR_ALREADY_INIT. Thus, it is an
- * error to register memory twice without resetting (i.e. closing) the
- * resource in between. This convention keeps the Linux driver from
- * having to track which particular devices a page is bound to.
- *
- * - At present, a memory registration is only cleared when the
- * service domain is reset. In this case, the Linux driver simply
- * closes the HV device file handle and then decrements the reference
- * counts of all pages that were previously registered with the
- * device.
- *
- * - In the future, we may add a mechanism for unregistering memory.
- * One possible implementation would require that the user specify
- * which buffer is currently registered. The HV would then verify
- * that that page was actually the one currently mapped and return
- * success or failure to Linux, which would then only decrement the
- * page reference count if the addresses were mapped. Another scheme
- * might allow Linux to pass a token to the HV to be returned when the
- * resource is unmapped.
- *
- * @subsection iorpc_interrupt INTERRUPT
- *
- * The INTERRUPT .idl datatype allows the client to bind hardware
- * interrupts to a particular combination of IPI parameters - CPU, IPI
- * PL, and event bit number. This data is passed via a special
- * datatype so that the Linux driver can validate the CPU and PL and
- * the HV generic iorpc code can translate client CPUs to real CPUs.
- *
- * @subsection iorpc_pollfd_setup POLLFD_SETUP
- *
- * The POLLFD_SETUP .idl datatype allows the client to set up hardware
- * interrupt bindings which are received by Linux but which are made
- * visible to user processes as state transitions on a file descriptor;
- * this allows user processes to use Linux primitives, such as poll(), to
- * await particular hardware events. This data is passed via a special
- * datatype so that the Linux driver may recognize the pollable file
- * descriptor and translate it to a set of interrupt target information,
- * and so that the HV generic iorpc code can translate client CPUs to real
- * CPUs.
- *
- * @subsection iorpc_pollfd POLLFD
- *
- * The POLLFD .idl datatype allows manipulation of hardware interrupt
- * bindings set up via the POLLFD_SETUP datatype; common operations are
- * resetting the state of the requested interrupt events, and unbinding any
- * bound interrupts. This data is passed via a special datatype so that
- * the Linux driver may recognize the pollable file descriptor and
- * translate it to an interrupt identifier previously supplied by the
- * hypervisor as the result of an earlier pollfd_setup operation.
- *
- * @subsection iorpc_blob BLOB
- *
- * The BLOB .idl datatype allows the client to write an arbitrary
- * length string of bytes up to the hypervisor driver. This can be
- * useful for passing up large, arbitrarily structured data like
- * classifier programs. The iorpc stack takes care of validating the
- * buffer VA and CPA as the data passes up to the hypervisor. Unlike
- * MEM_BUFFER(), the buffer is not registered - Linux does not bump
- * page refcounts and the HV driver should not reuse the buffer once
- * the system call is complete.
- *
- * @section iorpc_translation Translating User Space Calls
- *
- * The ::iorpc_offset structure describes the formatting of the offset
- * that is passed to pread() or pwrite() as part of the generated RPC code.
- * When the user calls up to Linux, the rpc code fills in all the fields of
- * the offset, including a 16-bit opcode, a 16 bit format indicator, and 32
- * bits of user-specified "sub-offset". The opcode indicates which syscall
- * is being requested. The format indicates whether there is a "prefix
- * struct" at the start of the memory buffer passed to pwrite(), and if so
- * what data is in that prefix struct. These prefix structs are used to
- * implement special datatypes like MEM_BUFFER() and INTERRUPT - we arrange
- * to put data that needs translation and permission checks at the start of
- * the buffer so that the Linux driver and generic portions of the HV iorpc
- * code can easily access the data. The 32 bits of user-specified
- * "sub-offset" are most useful for pread() calls where the user needs to
- * also pass in a few bits indicating which register to read, etc.
- *
- * The Linux iorpc driver watches for system calls that contain prefix
- * structs so that it can translate parameters and bump reference
- * counts as appropriate. It does not (currently) have any knowledge
- * of the per-device opcodes - it doesn't care what operation you're
- * doing to mPIPE, so long as it can do all the generic book-keeping.
- * The hv/iorpc.h header file defines all of the generic encoding bits
- * needed to translate iorpc calls without knowing which particular
- * opcode is being issued.
- *
- * @section iorpc_globals Global iorpc Calls
- *
- * Implementing mmap() required adding some special iorpc syscalls
- * that are only called by the Linux driver, never by userspace.
- * These include get_mmio_base() and check_mmio_offset(). These
- * routines are described in globals.idl and must be included in every
- * iorpc driver. By providing these routines in every driver, Linux's
- * mmap implementation can easily get the PTE bits it needs and
- * validate the PA offset without needing to know the per-device
- * opcodes to perform those tasks.
- *
- * @section iorpc_kernel Supporting gxio APIs in the Kernel
- *
- * The iorpc code generator also supports generation of kernel code
- * implementing the gxio APIs. This capability is currently used by
- * the mPIPE network driver, and will likely be used by the TRIO root
- * complex and endpoint drivers and perhaps an in-kernel crypto
- * driver. Each driver that wants to instantiate iorpc calls in the
- * kernel needs to generate a kernel version of the generate rpc code
- * and (probably) copy any related gxio source files into the kernel.
- * The mPIPE driver provides a good example of this pattern.

- * The @ref netio_input_register() function uses this structure to define
- * how an application tile will communicate with an IPP.
- *
- *
- * Future updates to NetIO may add new members to this structure,
- * which can affect the success of the registration operation. Thus,
- * if dynamically initializing the structure, applications are urged to
- * zero it out first, for example:
- *
- * @code
- * netio_input_config_t config;
- * memset(&config, 0, sizeof (config));
- * config.flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE;
- * config.num_receive_packets = NETIO_MAX_RECEIVE_PKTS;
- * config.queue_id = 0;
- * .
- * .
- * .
- * @endcode
- *
- * since that guarantees that any unused structure members, including
- * members which did not exist when the application was first developed,
- * will not have unexpected values.
- *
- * If statically initializing the structure, we strongly recommend use of
- * C99-style named initializers, for example:
- *
- * @code
- * netio_input_config_t config = {
- * .flags = NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE,
- * .num_receive_packets = NETIO_MAX_RECEIVE_PKTS,
- * .queue_id = 0,
- * },
- * @endcode
- *
- * instead of the old-style structure initialization:
- *
- * @code
- * // Bad example! Currently equivalent to the above, but don't do this.
- * netio_input_config_t config = {
- * NETIO_RECV | NETIO_XMIT_CSUM | NETIO_TAG_NONE, NETIO_MAX_RECEIVE_PKTS, 0
- * },
- * @endcode
- *
- * since the C99 style requires no changes to the code if elements of the
- * config structure are rearranged. (It also makes the initialization much
- * easier to understand.)
- *
- * Except for items which address a particular tile's transmit or receive
- * characteristics, such as the ::NETIO_RECV flag, applications are advised
- * to specify the same set of configuration data on all registrations.
- * This prevents differing results if multiple tiles happen to do their
- * registration operations in a different order on different invocations of
- * the application. This is particularly important for things like link
- * management flags, and buffer size and homing specifications.
- *
- * Unless the ::NETIO_FIXED_BUFFER_VA flag is specified in flags, the NetIO
- * buffer pool is automatically created and mapped into the application's
- * virtual address space at an address chosen by the operating system,
- * using the common memory (cmem) facility in the Tilera Multicore
- * Components library. The cmem facility allows multiple processes to gain
- * access to shared memory which is mapped into each process at an
- * identical virtual address. In order for this to work, the processes
- * must have a common ancestor, which must create the common memory using
- * tmc_cmem_init().
- *
- * In programs using the iLib process creation API, or in programs which use
- * only one process (which include programs using the pthreads library),
- * tmc_cmem_init() is called automatically. All other applications
- * must call it explicitly, before any child processes which might call
- * netio_input_register() are created.

- /** Registration characteristics.
-
- This value determines several characteristics of the registration;
- flags for different types of behavior are ORed together to make the
- final flag value. Generally applications should specify exactly
- one flag from each of the following categories:
-
- - Whether the application will be receiving packets on this queue
- (::NETIO_RECV or ::NETIO_NO_RECV).
-
- - Whether the application will be transmitting packets on this queue,
- and if so, whether it will request egress checksum calculation
- (::NETIO_XMIT, ::NETIO_XMIT_CSUM, or ::NETIO_NO_XMIT). It is
- legal to call netio_get_buffer() without one of the XMIT flags,
- as long as ::NETIO_RECV is specified; in this case, the retrieved
- buffers must be passed to another tile for transmission.
-
- - Whether the application expects any vendor-specific tags in
- its packets' L2 headers (::NETIO_TAG_NONE, ::NETIO_TAG_BRCM,
- or ::NETIO_TAG_MRVL). This must match the configuration of the
- target IPP.
-
- To accommodate applications written to previous versions of the NetIO
- interface, none of the flags above are currently required; if omitted,
- NetIO behaves more or less as if ::NETIO_RECV | ::NETIO_XMIT_CSUM |
- ::NETIO_TAG_NONE were used. However, explicit specification of
- the relevant flags allows NetIO to do a better job of resource
- allocation, allows earlier detection of certain configuration errors,
- and may enable advanced features or higher performance in the future,
- so their use is strongly recommended.
-
- Note that specifying ::NETIO_NO_RECV along with ::NETIO_NO_XMIT
- is a special case, intended primarily for use by programs which
- retrieve network statistics or do link management operations.
- When these flags are both specified, the resulting queue may not
- be used with NetIO routines other than netio_get(), netio_set(),
- and netio_input_unregister(). See @ref link for more information

- This array specifies the relative amount of buffering to place

- indexed by the NUMA node, and the values in the array are
- proportional to the amount of buffer space to allocate on that
- node.
-
- If memory striping is enabled in the Hypervisor, then there is
- only one logical NUMA node (node 0). In that case, NetIO will by
- default ignore the suggested buffer node weights, and buffers
- will be striped across the physical memory controllers. See
- UG209 System Programmer's Guide for a description of the
- hypervisor option that controls memory striping.
-
- If memory striping is disabled, then there are up to four NUMA
- nodes, corresponding to the four DDRAM controllers in the TILE
- processor architecture. See UG100 Tile Processor Architecture
- Overview for a diagram showing the location of each of the DDRAM
- controllers relative to the tile array.
-
- For instance, if memory striping is disabled, the following
- configuration strucure:
-
- @code
- netio_input_config_t config = {
- .
- .
- .
- .total_buffer_size = 4 * 16 * 1024 * 1024;
- .buffer_node_weights = { 1, 0, 1, 0 },
- },
- @endcode
-
- would result in 32 MB of buffers being placed on controller 0, and
- 32 MB on controller 2. (Since buffers are allocated in units of
- 16 MB, some sets of weights will not be able to be matched exactly.)
-
- For the weights to be effective, @ref total_buffer_size must be
- nonzero. If @ref total_buffer_size is zero, causing the default
- 32 MB of buffer space to be used, then any specified weights will
- be ignored, and buffers will positioned as they were in previous
- versions of NetIO:
-
- - For xgbe/0 and gbe/0, 16 MB of buffers will be placed on controller 1,
- and the other 16 MB will be placed on controller 2.
-
- - For xgbe/1 and gbe/1, 16 MB of buffers will be placed on controller 2,
- and the other 16 MB will be placed on controller 3.
-
- If @ref total_buffer_size is nonzero, but all weights are zero,
- then all buffer space will be allocated on Linux NUMA node zero.
-
- By default, the specified buffer placement is treated as a hint;
- if sufficient free memory is not available on the specified
- controllers, the buffers will be allocated elsewhere. However,
- if the ::NETIO_STRICT_HOMING flag is specified in @ref flags, then a
- failure to allocate buffer space exactly as requested will cause the
- registration operation to fail with an error of ::NETIO_CANNOT_HOME.
-
- Note that maximal network performance cannot be achieved with
- only one memory controller.

- * It does not use the stack, but since it might be re-interrupted by

- * Support routines for atomic operations. Each function takes:
- *
- * r0: address to manipulate
- * r1: pointer to atomic lock guarding this operation (for ATOMIC_LOCK_REG)
- * r2: new value to write, or for cmpxchg/add_unless, value to compare against
- * r3: (cmpxchg/xchg_add_unless) new value to write or add;
- * (atomic64 ops) high word of value to write
- * r4/r5: (cmpxchg64/add_unless64) new value to write or add
- *
- * The 32-bit routines return a "struct __get_user" so that the futex code
- * has an opportunity to return -EFAULT to the user if needed.
- * The 64-bit routines just return a "long long" with the value,
- * since they are only used from kernel space and don't expect to fault.
- * Support for 16-bit ops is included in the framework but we don't provide any.
- *
- * Note that the caller is advised to issue a suitable L1 or L2
- * prefetch on the address being manipulated to avoid extra stalls.
- * In addition, the hot path is on two icache lines, and we start with
- * a jump to the second line to make sure they are both in cache so
- * that we never stall waiting on icache fill while holding the lock.
- * (This doesn't work out with most 64-bit ops, since they consume
- * too many bundles, so may take an extra i-cache stall.)
- *
- * These routines set the INTERRUPT_CRITICAL_SECTION bit, just
- * like sys_cmpxchg(), so that NMIs like PERF_COUNT will not interrupt
- * the code, just page faults.
- *
- * If the load or store faults in a way that can be directly fixed in
- * the do_page_fault_ics() handler (e.g. a vmalloc reference) we fix it
- * directly, return to the instruction that faulted, and retry it.
- *
- * If the load or store faults in a way that potentially requires us
- * to release the atomic lock, then retry (e.g. a migrating PTE), we
- * reset the PC in do_page_fault_ics() to the "tns" instruction so
- * that on return we will reacquire the lock and restart the op. We
- * are somewhat overloading the exception_table_entry notion by doing
- * this, since those entries are not normally used for migrating PTEs.
- *
- * If the main page fault handler discovers a bad address, it will see
- * the PC pointing to the "tns" instruction (due to the earlier
- * exception_table_entry processing in do_page_fault_ics), and
- * re-reset the PC to the fault handler, atomic_bad_address(), which
- * effectively takes over from the atomic op and can either return a
- * bad "struct __get_user" (for user addresses) or can just panic (for
- * bad kernel addresses).
- *
- * Note that if the value we would store is the same as what we
- * loaded, we bypass the store. Other platforms with true atomics can
- * make the guarantee that a non-atomic __clear_bit(), for example,
- * can safely race with an atomic test_and_set_bit(); this example is
- * from bit_spinlock.h in slub_lock() / slub_unlock(). We can't do
- * that on Tile since the "atomic" op is really just a
- * read/modify/write, and can race with the non-atomic
- * read/modify/write. However, if we can short-circuit the write when
- * it is not needed, in the atomic case, we avoid the race.
