eal: clean up export of socket id variable Theres no need to export this variable. Its set and queried from an API call that doesn't exist in the hot path. Instead just export the rte_socket_id symbol and make the variable private to protect it from type changes.

This function allows DPDK to become more like an ordinary library, where the library context itself can be initialized and cleaned up by the application. The rte_exit() and rte_panic() functions must be considered, particularly if they should call rte_eal_cleanup() to release any resources or not. This patch adds the cleanup to rte_exit(), but does not clean up on rte_panic().

devargs: introduce insert function Some buses will operate either in whitelist or blacklist mode. This mode is currently passed down by the rte_eal_devargs_add function with the devtype argument. When inserting devices using the hotplug API, the implicit assumption is that this device is being whitelisted, meaning that it is explicitly requested by the application to be used. This can conflict with the initial bus configuration. While the rte_eal_devargs_add API is being deprecated soon, it cannot be modified at the moment to accommodate this situation. As such, this new experimental API offers a bare interface for inserting rte_devargs without directly manipulating the global rte_devargs list. This new function expects a fully-formed rte_devargs, previously parsed and allocated. It does not check whether the new rte_devargs is compatible with current bus configuration, but will replace any eventual existing one for the same device, allowing the hotplug operation to proceed. i.e. a previously blacklisted device can be redefined as being whitelisted.

Its DEVTYPE parameter is currently only used to specify scan policies, and those will evolve in the next release. This evolution should rationalize the rte_devargs API. As such, the proposed API here is not the most convenient, but is taylored to follow the current design and integrate easily with its main use within rte_eal_hotplug_* functions.

eal: add shared indexed file-backed array rte_fbarray is a simple indexed array stored in shared memory via mapping files into memory. Rationale for its existence is the following: since we are going to map memory page-by-page, there could be quite a lot of memory segments to keep track of (for smaller page sizes, page count can easily reach thousands). We can't really make page lists truly dynamic and infinitely expandable, because that involves reallocating memory (which is a big no-no in multiprocess). What we can do instead is have a maximum capacity as something really, really large, and decide at allocation time how big the array is going to be. We map the entire file into memory, which makes it possible to use fbarray as shared memory, provided the structure itself is allocated in shared memory. Per-fbarray locking is also used to avoid index data races (but not contents data races - that is up to user application to synchronize). In addition, in understanding that we will frequently need to scan this array for free space and iterating over array linearly can become slow, rte_fbarray provides facilities to index array's usage. The following use cases are covered: - find next free/used slot (useful either for adding new elements to fbarray, or walking the list) - find starting index for next N free/used slots (useful for when we want to allocate chunk of VA-contiguous memory composed of several pages) - find how many contiguous free/used slots there are, starting from specified index (useful for when we want to figure out how many pages we have until next hole in allocated memory, to speed up some bulk operations where we would otherwise have to walk the array and add pages one by one) This is accomplished by storing a usage mask in-memory, right after the data section of the array, and using some bit-level magic to figure out the info we need.

eal: register log type and pick level from args Dynamic log types are registered on RTE_INIT() step. This allows one to set log levels by EAL options on application launch. However, this does not allow to manage log types if they are created during runtime. EAL does not store log levels and types passed from the command line. Thus, they cannot be picked later. This is an obvious flaw since it would be better to be able to pick levels for dynamic types registered for runtime-determined facilities such as NIC ports. This patch provides a mechanism to store log levels passed from EAL options and adds an API to register log types and pick levels from the internal storage.

eal: add channel for multi-process communication Previouly, there are three channels for multi-process (i.e., primary/secondary) communication. 1. Config-file based channel, in which, the primary process writes info into a pre-defined config file, and the secondary process reads the info out. 2. vfio submodule has its own channel based on unix socket for the secondary process to get container fd and group fd from the primary process. 3. pdump submodule also has its own channel based on unix socket for packet dump. It'd be good to have a generic communication channel for multi-process communication to accommodate the requirements including: a. Secondary wants to send info to primary, for example, secondary would like to send request (about some specific vdev to primary). b. Sending info at any time, instead of just initialization time. c. Share FDs with the other side, for vdev like vhost, related FDs (memory region, kick) should be shared. d. A send message request needs the other side to response immediately. This patch proposes to create a communication channel, based on datagram unix socket, for above requirements. Each process will block on a unix socket waiting for messages from the peers. Three new APIs are added: 1. rte_eal_mp_action_register() is used to register an action, indexed by a string, when a component at receiver side would like to response the messages from the peer processe. 2. rte_eal_mp_action_unregister() is used to unregister the action if the calling component does not want to response the messages. 3. rte_eal_mp_sendmsg() is used to send a message, and returns immediately. If there are n secondary processes, the primary process will send n messages.

eal: add synchronous multi-process communication We need the synchronous way for multi-process communication, i.e., blockingly waiting for reply message when we send a request to the peer process. We add two APIs rte_eal_mp_request() and rte_eal_mp_reply() for such use case. By invoking rte_eal_mp_request(), a request message is sent out, and then it waits there for a reply message. The caller can specify the timeout. And the response messages will be collected and returned so that the caller can decide how to translate them. The API rte_eal_mp_reply() is always called by an mp action handler. Here we add another parameter for rte_eal_mp_t so that the action handler knows which peer address to reply. sender-process receiver-process ---------------------- ---------------- thread-n |_rte_eal_mp_request() ----------> mp-thread |_timedwait() |_process_msg() |_action() |_rte_eal_mp_reply() mp_thread <---------------------| |_process_msg() |_signal(send_thread) thread-m <----------| |_collect-reply * A secondary process is only allowed to talk to the primary process. * If there are multiple secondary processes for the primary process, it will send request to peer1, collect response from peer1; then send request to peer2, collect response from peer2, and so on. * When thread-n is sending request, thread-m of that process can send request at the same time. * For pair <action_name, peer>, we guarantee that only one such request is on the fly.

eal: add IPC asynchronous request This API is similar to the blocking API that is already present, but reply will be received in a separate callback by the caller (callback specified at the time of request, rather than registering for it in advance). Under the hood, we create a separate thread to deal with replies to asynchronous requests, that will just wait to be notified by the main thread, or woken up on a timer.

service: return integer service id from register This commit reworks the service register function to accept an extra parameter. The parameter is a uint32_t *, which when provided will be set to the integer service_id that the newly registered service is represented by. This is useful for services that wish to validate settings at a later point in time - they need to know their own service id. This commit updates the eventdev sw pmd, as well as unit tests to use the new register API.

service: add component runstate This commit adds a new flag that the component (or "backend") can use to indicate readyness. The service function callback will not be called until the component sets itself as ready. The use-case behind adding this feature is eg: a service that requires configuration before it can start. Any service that emulates an ethdev will have rte_eth_dev_configure() called, and only after that the service will know how many queues/etc to allocate. Once that configuration is complete, the service marks itself as ready using rte_service_component_runstate_set(). This feature request results from prototyping services, and requiring a flag in each service to note "internal" readyness. Instead that logic is now lifted to the service library. The unit tests have been updated to test the component runstate. Signed-off-by: Harry van Haaren <harry.van.haaren@intel.com> Acked-by: Pavan Nikhilesh <pbhagavatula@caviumnetworks.com>

service: add function to run on app lcore This commit adds a new function which allows an application lcore (aka; *not* a dedicated service-lcore) to run a service. This function is required to allow applications to gradually port functionality to using services, while still being able to run ordinary application functions. This requirement became clear when a patch to the existing eventdev/pipeline sample app was modified to use a service-core for scheduling - and that same core should be capable of running the "worker()" function from the application too. This patch refactors the existing running code into a smaller "service_run" function, which can be called by the dedicated service-core loop, and the newly added function.
