046395d7ab181288d14737c1d0041e98328f473f	09-Apr-2014	Jens Axboe <axboe@fb.com>	Add exit_on_io_done option to the CPU IO engine The CPU IO engine is most often used to saturate the system, while running an IO load on it. As such, it's useful to have CPU engine threads exit automatically, when IO has completed. Add exit_on_io_done as a CPU IO engine option for that purpose.

a8075704d3392fede7bd7cfa394616fa0eed7ae0	13-Feb-2014	Daniel Gollub <daniel.gollub@t-online.de>	Introduce get_ioengine for external engines This makes life easier for plugins written in C++ since they do not need to deal with struct initilization issues with the ioengine_ops symbol. With g++ a non-static ioengine_ops in global scope like this: struct ioengine_ops ioengine = { .name = "null", .version = FIO_IOOPS_VERSION, .queue = fio_null_queue, .commit = fio_null_commit, }; Results in: cpp_null2.cc: At global scope: cpp_null2.cc:112:1: error: C99 designator ‘name’ outside aggregate initializer cpp_null2.cc:112:1: sorry, unimplemented: non-trivial designated initializers not supported cpp_null2.cc:112:1: sorry, unimplemented: non-trivial designated initializers not supported cpp_null2.cc:112:1: sorry, unimplemented: non-trivial designated initializers not supported cpp_null2.cc:112:1: sorry, unimplemented: non-trivial designated initializers not supported $ Example get_iongine() symbol usage: ---8<--- extern "C" { void get_ioengine(struct ioengine_ops *ioengine_ptr) { struct ioengine_ops ioengine; ioengine_ptr = (struct ioengine_ops ) malloc(sizeof(struct ioengine_ops)); ioengine = *ioengine_ptr; strcpy(ioengine->name, "cpp_null"); ioengine->version = FIO_IOOPS_VERSION; ioengine->queue = fio_null_queue; ioengine->commit = fio_null_commit; ioengine->getevents = fio_null_getevents; ioengine->event = fio_null_event; ioengine->init = fio_null_init; ioengine->cleanup = fio_null_cleanup; ioengine->open_file = fio_null_open; ioengine->flags = FIO_DISKLESSIO; } } --->8--- Signed-off-by: Daniel Gollub <d.gollub@telekom.de> Moved get_ioengine_t typedef to ioengine.h.

a05d62b28f18e37256f2698106169b1177708cc1	15-Mar-2012	Yufei Ren <renyufei83@gmail.com>	rdma engine graceful teardown For rdma ioengine's one side operation, RDMA_WRITE or RDMA_READ, server side gets a message from client side that the task is finished. In previous version, the server simply exit() in td_io_commit() which causes segmentation fault in thread mode or process hanging in process mode. This patch achieves graceful tear down by setting up `td->done` as UDP engine did. Signed-off-by: Jens Axboe <axboe@kernel.dk> /external/fio/ioengines.c
214ac7e009897f8f82ab9e21aff9bc86d33bb470	15-Mar-2012	Dan Ehrenberg <dehrenberg@google.com>	New offset_increment option This patch adds a new option to fio job files. It is described in the HOWTO as follows: offset_increment=int If this is provided, then the real offset becomes the offset + offset_increment * thread_number, where the thread number is a counter that starts at 0 and is incremented for each job. This option is useful if there are several jobs which are intended to operate on a file in parallel in disjoint segments, with even spacing between the starting points.

Rate limiting logic was using thread_data->cur_depth to decide the min_evts number to ask for during its "flush" prior to sleeping. td->cur_depth, however, does not properly track in-flight IOs submitted to the async engines. Added field to thread_data structure and use that, instead, to track IOs currently in flight.

de890a1e48d40238dac69f302708dde8719de240	09-Nov-2011	Steven Lang <tirea@google.com>	Private parameters for ioengines Here is the polished version of the engine private options patch. As discussed, the global section only ever tracks the private options for the globally defined ioengine. For command line parameters, the ioengine must be selected before any private options are used. (IE --ioengine=libaio --userspace_reap will work, but --userspace_reap --ioengine=libaio will not.) The userspace_reap option from libaio has been moved over to this new option method, usage should be identical to before. The net ioengine has been modified to use parameters, with hostname, port, protocol and listen defined as ioengine private parameters. The old style of hostname=host,port,protocol no longer works, so usage will need to be updated. (It will spit out an error that should be clear enough that it changed if this is tried.) Also, with the new way for specifying parameters, the net IO engine now allows data to flow in either direction on TCP connections, regardless of which end initiates the connection. There's also a new command line argument --enghelp which can be used to get help on ioengine private parameters, similar to --cmdhelp. With no argument, it lists all built-in ioengine. The argument is an ioengine name (Or path to .so) and optionally a comma followed by a command name, which behaves identically to --cmdhelp. For ioengine authorship, if options are supplied, both the options structure and the size of the storage needed must be supplied, and the storage must be large enough to hold a pointer to struct thread_data; that is because the options callback doesn't explicitly have a pointer to the thread data (Normally it relies on the fact that the options struct is the start of the thread data), so the offset 0 of the struct must point to the thread data, and is filled in automatically. (This also neatly provides a guarantee that offset 0 is reserved in the options data, so it can be safely used as a test of undefined.)
