The basic idea is they count "things that are in + * progress" - in flight bios, some other thread that's doing something else - + * anything you might want to wait on. + * + * The refcount may be manipulated with closure_get() and closure_put(). + * closure_put() is where many of the interesting things happen, when it causes + * the refcount to go to 0. + * + * Closures can be used to wait on things both synchronously and asynchronously, + * and synchronous and asynchronous use can be mixed without restriction. To + * wait synchronously, use closure_sync() - you will sleep until your closure's + * refcount hits 1. + * + * To wait asynchronously, use + * continue_at(cl, next_function, workqueue); + * + * passing it, as you might expect, the function to run when nothing is pending + * and the workqueue to run that function out of. + * + * continue_at() also, critically, requires a 'return' immediately following the + * location where this macro is referenced, to return to the calling function. + * There's good reason for this. + * + * To use safely closures asynchronously, they must always have a refcount while + * they are running owned by the thread that is running them. Otherwise, suppose + * you submit some bios and wish to have a function run when they all complete: + * + * foo_endio(struct bio *bio) + * { + * closure_put(cl); + * } + * + * closure_init(cl); + * + * do_stuff(); + * closure_get(cl); + * bio1->bi_endio = foo_endio; + * bio_submit(bio1); + * + * do_more_stuff(); + * closure_get(cl); + * bio2->bi_endio = foo_endio; + * bio_submit(bio2); + * + * continue_at(cl, complete_some_read, system_wq); + * + * If closure's refcount started at 0, complete_some_read() could run before the + * second bio was submitted - which is almost always not what you want! More + * importantly, it wouldn't be possible to say whether the original thread or + * complete_some_read()'s thread owned the closure - and whatever state it was + * associated with! + * + * So, closure_init() initializes a closure's refcount to 1 - and when a + * closure_fn is run, the refcount will be reset to 1 first. + * + * Then, the rule is - if you got the refcount with closure_get(), release it + * with closure_put() (i.e, in a bio->bi_endio function). If you have a refcount + * on a closure because you called closure_init() or you were run out of a + * closure - _always_ use continue_at(). Doing so consistently will help + * eliminate an entire class of particularly pernicious races. + * + * Lastly, you might have a wait list dedicated to a specific event, and have no + * need for specifying the condition - you just want to wait until someone runs + * closure_wake_up() on the appropriate wait list. In that case, just use + * closure_wait(). It will return either true or false, depending on whether the + * closure was already on a wait list or not - a closure can only be on one wait + * list at a time. + * + * Parents: + * + * closure_init() takes two arguments - it takes the closure to initialize, and + * a (possibly null) parent. + * + * If parent is non null, the new closure will have a refcount for its lifetime; + * a closure is considered to be "finished" when its refcount hits 0 and the + * function to run is null. Hence + * + * continue_at(cl, NULL, NULL); + * + * returns up the (spaghetti) stack of closures, precisely like normal return + * returns up the C stack. continue_at() with non null fn is better thought of + * as doing a tail call. + * + * All this implies that a closure should typically be embedded in a particular + * struct (which its refcount will normally control the lifetime of), and that + * struct can very much be thought of as a stack frame. + */ + +struct closure; +struct closure_syncer; +typedef void (closure_fn) (struct closure *); +extern struct dentry *bcache_debug; + +struct closure_waitlist { + struct llist_head list; +}; + +enum closure_state { + /* + * CLOSURE_WAITING: Set iff the closure is on a waitlist.

+ +/* + * CpuCP Primary Queue Packets + * + * During normal operation, the host's kernel driver needs to send various + * messages to CpuCP, usually either to SET some value into a H/W periphery or + * to GET the current value of some H/W periphery. For example, SET the + * frequency of MME/TPC and GET the value of the thermal sensor. + * + * These messages can be initiated either by the User application or by the + * host's driver itself, e.g. power management code. In either case, the + * communication from the host's driver to CpuCP will *always* be in + * synchronous mode, meaning that the host will send a single message and poll + * until the message was acknowledged and the results are ready (if results are + * needed). + * + * This means that only a single message can be sent at a time and the host's + * driver must wait for its result before sending the next message. Having said + * that, because these are control messages which are sent in a relatively low + * frequency, this limitation seems acceptable. It's important to note that + * in case of multiple devices, messages to different devices *can* be sent + * at the same time. + * + * The message, inputs/outputs (if relevant) and fence object will be located + * on the device DDR at an address that will be determined by the host's driver. + * During device initialization phase, the host will pass to CpuCP that address. + * Most of the message types will contain inputs/outputs inside the message + * itself. The common part of each message will contain the opcode of the + * message (its type) and a field representing a fence object. + * + * When the host's driver wishes to send a message to CPU CP, it will write the + * message contents to the device DDR, clear the fence object and then write to + * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU. + * + * Upon receiving the interrupt (#121), CpuCP will read the message from the + * DDR. In case the message is a SET operation, CpuCP will first perform the + * operation and then write to the fence object on the device DDR. In case the + * message is a GET operation, CpuCP will first fill the results section on the + * device DDR and then write to the fence object. If an error occurred, CpuCP + * will fill the rc field with the right error code. + * + * In the meantime, the host's driver will poll on the fence object. Once the + * host sees that the fence object is signaled, it will read the results from + * the device DDR (if relevant) and resume the code execution in the host's + * driver. + * + * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8 + * so the value being put by the host's driver matches the value read by CpuCP + * + * Non-QMAN packets should be limited to values 1 through (2^8 - 1) + * + * Detailed description: + * + * CPUCP_PACKET_DISABLE_PCI_ACCESS - + * After receiving this packet the embedded CPU must NOT issue PCI + * transactions (read/write) towards the Host CPU.
