1 2006-10-30 Jack Morgenstein <jackm@mellanox.co.il>
3 * src/cmd.c (ibv_cmd_query_qp): Unmarshall sq_draining instead of
6 * include/infiniband/kern-abi.h: Change en_sqd_async_notify member
7 of struct ibv_query_qp_resp to sq_draining.
9 2006-10-30 Roland Dreier <rdreier@cisco.com>
11 * src/init.c (find_drivers): Make find_drivers() take a const
12 directory name, and tweak how we strip trailing /s so that we
13 don't have to modify the directory name passed in. Constify
16 2006-10-25 Roland Dreier <rdreier@cisco.com>
18 * src/init.c (init_drivers): Remove assignment to dev->driver now
19 that it is gone for good.
21 * include/infiniband/verbs.h: Remove .driver member of struct
22 ibv_device, since it is never really used.
24 2006-10-17 Roland Dreier <rdreier@cisco.com>
26 * include/infiniband/arch.h: Update i386 and x86_64 memory barrier
27 macros to be more than compiler barriers, to guard against
28 out-of-order speculative reads.
30 * include/infiniband/arch.h: Add rmb() and wmb() macros in
31 addition to the full mb(), so that low-level drivers can ask for
32 weaker ordering if that's all that is needed.
34 2006-10-03 Roland Dreier <rdreier@cisco.com>
36 * src/cmd.c (ibv_cmd_get_context_v2, ibv_cmd_get_context)
37 (ibv_cmd_query_device, ibv_cmd_query_port, ibv_cmd_alloc_pd)
38 (ibv_cmd_reg_mr, ibv_cmd_create_cq_v2, ibv_cmd_create_cq)
39 (ibv_cmd_poll_cq, ibv_cmd_resize_cq, ibv_cmd_destroy_cq)
40 (ibv_cmd_create_srq, ibv_cmd_create_qp, ibv_cmd_post_send)
41 (ibv_cmd_post_recv, ibv_cmd_post_srq_recv, ibv_cmd_create_ah)
42 (ibv_cmd_destroy_qp): Annotate so that Valgrind knows responses
43 are defined after write() succeeds. The kernel writes into the
44 response structure directly, so without these, Valgrind thinks
45 that response structures are undefined memory. This is based on
46 patches and suggestions by Rainer Keller <keller@hlrs.de>, Jeff
47 Squyres <jsquyres@cisco.com> and Siqing Fan.
49 * src/ibverbs.h: Add wrapper for VALGRIND_MAKE_MEM_DEFINED so that
50 it can be used in .c files without worrying about whether Valgrind
51 is installed or enabled.
53 * configure.in: Add support for Valgrind annotation (enabled with
54 --with-valgrind option to configure).
56 * src/cmd.c (ibv_cmd_query_port, ibv_cmd_create_cq,
57 ibv_cmd_modify_qp): Set reserved fields to 0 to avoid future
58 problems and also to make Valgrind a little quieter.
60 * src/init.c (init_drivers): Set node_type and transport_type
61 values of device being created.
63 * include/infiniband/verbs.h: Add ibv_node_type enum value
64 IBV_NODE_RNIC, and add enum ibv_transport_type. Add node_type and
65 transport_type fields to struct ibv_device.
67 2006-09-12 Roland Dreier <rdreier@cisco.com>
69 * include/infiniband/verbs.h: Swap wr_id and next members of
70 struct ibv_send_wr and struct ibv_recv_wr. This allows wr_id to
71 be naturally aligned without padding on 32-bit platforms.
73 2006-08-23 Roland Dreier <rdreier@cisco.com>
75 * include/infiniband/driver.h: Add a definition of the macro
76 IBV_CMD_RESIZE_CQ_HAS_RESP_PARAMS so that low-level driver plugins
77 can detect the changed signature of ibv_cmd_resize_cq().
79 2006-08-23 Ralph Campbell <ralph.campbell@qlogic.com>
81 * src/cmd.c (ibv_cmd_resize_cq): Add resp and resp_size parameters
82 so that the low-level driver in the kernel can return
83 device-specific information from the resize CQ operation.
85 2006-07-26 Roland Dreier <rdreier@cisco.com>
87 * src/verbs.c (ibv_reg_mr, ibv_dereg_mr): Add calls to
88 ibv_dontfork_range() and ibv_dofork_range() for memory regions
89 registered by library consumers.
91 * include/infiniband/verbs.h: Add declaration of ibv_fork_init().
93 * include/infiniband/driver.h: Add declarations of
94 ibv_dontfork_range() and ibv_dofork_range().
96 * src/memory.c: Rewrite to use a red-black tree instead of a
97 linked list. Change from doing mlock()/munlock() to
98 madvise(..., MADV_DONTFORK) and madvise(..., MADV_DOFORK), and
99 change the name of the entry points to ibv_dontfork_range() and
100 ibv_dofork_range(). Add ibv_fork_init() for applications to
101 request fork-safe behavior.
103 * src/ibverbs.h: Kill off unused declarations.
105 * src/init.c (ibverbs_init): Get rid of call to ibv_init_mem_map().
107 * include/infiniband/verbs.h: Add addr and length field to struct
108 ibv_mr so that memory regions can be madvised(). This changes the
109 ABI, since the layout of struct ibv_mr is changed.
111 2006-07-04 Roland Dreier <rdreier@cisco.com>
113 * include/infiniband/arch.h: Fix typo in sparc mb()
114 implementation: the asm should just be empty -- the "sync"
115 instruction was mistakenly cut and pasted from the ppc version.
117 2006-06-07 Sean Hefty <sean.hefty@intel.com>
119 * src/verbs.c include/infiniband/verbs.h: Add new routines:
120 ibv_init_ah_from_wc() and ibv_create_ah_from_wc() to simplify UD QP
123 * src/marshall.c include/infiniband/marshall.h: Expose
124 ibv_copy_ah_attr_from_kern to retrieve ibv_ah_attr from kernel for
127 2006-06-01 Roland Dreier <rdreier@cisco.com>
129 * src/device.c (ibv_get_device_list): Actually return a
130 NULL-terminated array as the documentation promises.
132 2006-05-31 Roland Dreier <rdreier@cisco.com>
134 * src/init.c (find_drivers): Fix memory leak: the result of
135 asprintf() needs to be freed when we're done with it.
137 * examples/asyncwatch.c (event_name_str): Print human-readable
138 form of IBV_EVENT_CLIENT_REREGISTER.
140 2006-05-31 Leonid Arsh <leonida@voltaire.com>
142 * include/infiniband/verbs.h: Add IBV_EVENT_CLIENT_REREGISTER.
144 2006-05-22 Roland Dreier <rdreier@cisco.com>
146 * examples/devinfo.c (print_hca_cap): Read board_id attribute from
147 sysfs using ibv_read_sysfs_file() instead of libsysfs.
149 * src/cmd.c, src/marshall.c, src/sysfs.c: Include <string.h>,
150 since it is no longer implicitly included via <sysfs/libsysfs.h>.
152 * include/infiniband/driver.h, include/infiniband/verbs.h,
153 src/device.c, src/init.c, src/verbs.c: Remove dependency on
154 libsysfs by implementing what is required directly on top of
155 filesystem operations.
157 * include/infiniband/driver.h, src/init.c: Change name of driver
158 entry point to ibv_driver_init(), and update prototype to remove
161 * src/marshall.c, include/infiniband/marshall.h,
162 include/infiniband/sa.h: Remove deprecated ib_xxx symbols.
164 * Makefile.am: Bump SONAME to 2, since libibverbs 1.1 will be
165 ABI-incompatible with libibverbs 1.0.
167 * Create libibverbs 1.1 branch and bump version number to 1.1-pre1.
169 2006-05-22 Michael S. Tsirkin <mst@mellanox.co.il>
171 * include/infiniband/verbs.h: Remove trailing commas from
172 enumerators to quiet warnings from obsolete compilers.
174 2006-05-02 Roland Dreier <rdreier@cisco.com>
176 * Release version 1.0.3.
178 2006-05-01 Roland Dreier <rdreier@cisco.com>
180 * include/infiniband/arch.h: Only SPARC V9 ISA supports membar.
181 So just use generic memory barrier for older sparc archs.
183 2006-04-11 Roland Dreier <rdreier@cisco.com>
185 * src/sysfs.c (ibv_read_sysfs_file): Fix memory leak if open fails.
187 * src/device.c (ibv_get_device_guid), src/verbs.c (ibv_query_gid,
188 ibv_query_pkey), src/init.c (init_drivers, check_abi_version): Use
189 libibverbs functions instead of libsysfs functions to get to sysfs.
191 * src/sysfs.c (ibv_get_sysfs_path, ibv_read_sysfs_file): Add some
192 simple functions for accessing sysfs without using libsysfs.
194 * include/infiniband/sa-kern-abi.h: Deprecate struct
195 ib_kern_path_rec name; struct ibv_kern_path_rec is now preferred.
197 * include/infiniband/sa.h: Deprecate struct ib_sa_XXX names;
198 struct ibv_sa_XXX is now preferred.
200 * src/marshall.c, include/infiniband/marshall.h: Deprecate
201 ib_copy_XXX() names; ibv_copy_XXX() is preferred. Add stub
202 wrappers with the old names so old binaries still work.
204 2006-04-11 Hoang-Nam Nguyen <HNGUYEN@de.ibm.com>
206 * src/verbs.c (ibv_rate_to_mult, mult_to_ibv_rate): Add new
207 functions to convert between IB rate enums and multiples of the
208 base 2.5 Gb/sec rate.
210 2006-04-11 Roland Dreier <rdreier@cisco.com>
212 * include/infiniband/verbs.h: Add __attribute_const macro to
213 portably mark functions as __attribute__((const))
215 2006-03-28 Roland Dreier <rdreier@cisco.com>
217 * src/init.c (load_driver): Print warning if dlopen() of a driver
220 2006-03-22 Dotan Barak <dotanb@mellanox.co.il>
222 * examples/asyncwatch.c: Print asynchronous event name as well as
225 2006-03-22 Roland Dreier <rdreier@cisco.com>
227 * include/infiniband/verbs.h (ibv_req_notify_cq): Document
230 2006-03-16 Roland Dreier <rdreier@cisco.com>
232 * src/cmd.c, src/device.c, src/memory.c, src/verbs.c: Add include
233 of <stdlib.h> to get a declaration of free() and avoid compile
236 2006-03-14 Roland Dreier <rdreier@cisco.com>
238 * Release version 1.0.2.
240 * Makefile.am (EXTRA_DIST): Remove debian/ directory from
241 tarballs, since Debian policy is that upstream tarballs should not
244 2006-03-13 Roland Dreier <rdreier@cisco.com>
246 * Release version 1.0.1.
248 * src/init.c (check_abi_version), src/verbs.c (ibv_query_gid,
249 ibv_query_pkey): Use sysfs_open_attribute() and
250 sysfs_read_attribute() instead of the deprecated function
251 sysfs_read_attribute_value(), which is no longer present in
252 libsysfs2 (which is already in Debian and Ubuntu).
254 * Release version 1.0.
256 2006-03-06 Roland Dreier <rdreier@cisco.com>
258 * include/infiniband/verbs.h: Add enum ibv_rate to define encoding
259 of static_rate field (based on a patch from Jack Morgenstein
260 <jackm@mellanox.co.il>).
262 2006-03-06 Ralph Campbell <ralphc@pathscale.com>
264 * src/init.c (find_drivers): Fix minor memory leak: call
265 globfree() to free memory allocated by glob().
267 2006-02-23 Dotan Barak <dotanb@mellanox.co.il>
269 * src/cmd.c (ibv_cmd_create_srq): Add support for kernel ABI
270 version 6 (take SRQ capacity from kernel response to create SRQ).
272 2006-02-16 Roland Dreier <rdreier@cisco.com>
274 * Release version 1.0-rc7.
276 * src/cmd.c (ibv_cmd_create_qp): Add support for kernel ABI
277 version 5 (properly aligned struct ibv_create_qp_resp).
279 2006-02-15 Roland Dreier <rdreier@cisco.com>
281 * src/cmd.c (ibv_cmd_create_qp): Allow userspace device-specific
282 driver to pass in a response buffer, so that the low-level driver
283 in the kernel can pass back device-specific information. This
284 changes the userspace driver API, since the signature of
285 ibv_cmd_create_qp() is changed.
287 2006-02-14 Roland Dreier <rdreier@cisco.com>
289 * Release version 1.0-rc6.
291 2006-02-13 Dotan Barak <dotanb@mellanox.co.il>
293 * examples/devinfo.c (print_hca_cap): Print board_id from sysfs,
296 2006-02-13 Roland Dreier <rdreier@cisco.com>
298 * examples/asyncwatch.c, examples/device_list.c,
299 examples/devinfo.c: Remove cpu_to_be64()/be64_to_cpu() and use
300 htonll()/ntohll() from <infiniband/arch.h>.
302 2006-02-13 Dotan Barak <dotanb@mellanox.co.il>
304 * src/cmd.c (ibv_cmd_query_qp, ibv_cmd_query_srq),
305 include/infiniband/driver.h: Add driver interface for calling
306 query QP and query SRQ kernel commands.
308 * include/infiniband/kern-abi.h: Add kernel ABI for query QP and
311 * src/verbs.c (ibv_query_qp, ibv_query_srq),
312 include/infiniband/verbs.h: Add query QP and query SRQ library
313 APIs. This changes the provider ABI, since new fields are added
314 to struct ibv_context_ops; source compatibility with provider
315 libraries is preserved, but binaries will have to be recompiled.
316 Neither source nor binary compatibility with consumers of
317 libibverbs is affected.
319 2006-02-01 Roland Dreier <rdreier@cisco.com>
321 * examples/rc_pingpong.c, examples/uc_pingpong.c,
322 examples/ud_pingpong.c, examples/srq_pingpong.c: Fix bug in
323 searching for device by name when there's more than one device.
325 2006-01-31 Roland Dreier <rdreier@cisco.com>
327 * include/infiniband/verbs.h, include/infiniband/driver.h: Remove
328 useless "extern" from function declarations.
330 2006-01-26 Roland Dreier <rdreier@cisco.com>
332 * include/infiniband/driver.h, src/cmd.c (ibv_cmd_resize_cq): Add
333 driver interface for calling resize CQ kernel command.
335 * include/infiniband/kern-abi.h: Add resize CQ kernel ABI.
337 * include/infiniband/verbs.h, src/verbs.c (ibv_resize_cq): Add
338 resize CQ library API. This changes the provider ABI, since a new
339 field is added to struct ibv_context_ops; source compatibility
340 with provider libraries is preserved, but binaries will have to be
341 recompiled. Neither source nor binary compatibility with
342 consumers of libibverbs is affected.
344 2006-01-25 Roland Dreier <rdreier@cisco.com>
346 * examples/pingpong.c, examples/pingpong.h,
347 examples/rc_pingpong.c, examples/uc_pingpong.c,
348 examples/srq_pingpong.c: Move pp_get_local_lid() to pingpong.c to
349 reduce code duplication.
351 2006-01-22 Roland Dreier <rdreier@cisco.com>
353 * Release version 1.0-rc5.
355 2006-01-22 Dotan Barak <dotanb@mellanox.co.il>
357 * examples/devinfo.c (main): Make ibv_devinfo list all IB devices
358 by default, rather than the first device only.
360 2006-01-20 Roland Dreier <rdreier@cisco.com>
362 * examples/rc_pingpong.c, examples/uc_pingpong.c,
363 examples/srq_pingpong.c: Add "-m/--mtu=" option to set path MTU.
364 (Based on a patch from Ralph Campbell <ralphc@pathscale.com>)
366 * examples/pingpong.c, examples/pingpong.h: Create generic
367 pingpong files so that we can start factoring out common code from
368 the pingpong examples. Start with functions to convert MTU to an
371 2006-01-17 Ralph Campbell <ralphc@pathscale.com>
373 * examples/rc_pingpong.c (main), examples/srq_pingpong.c (main),
374 examples/uc_pingpong.c (main), examples/ud_pingpong.c (main): Fix
375 race when using CQ events by arming CQ before allowing remote side
378 2006-01-06 Roland Dreier <rdreier@cisco.com>
380 * examples/srq_pingpong.c (main): Fix SRQ example to avoid
381 problems with many QPs and events. Based on a patch from Dotan
382 Barak (who also found the problem).
384 2006-01-06 Ralph Campbell <ralphc@pathscale.com>
386 * examples/rc_pingpong.c (main), examples/srq_pingpong.c (main),
387 examples/uc_pingpong.c (main), examples/ud_pingpong.c (main): Fix
388 test of return value of ibv_poll_cq().
390 2006-01-04 Dotan Barak <dotanb@mellanox.co.il>
392 * include/infiniband/verbs.h: Fix mask names in description of
395 2006-01-04 Michael S. Tsirkin <mst@mellanox.co.il>
397 * src/init.c (ibverbs_init): Fix ibverbs_init for multiple adapters.
398 Noted by Christoph Raisch.
400 2005-12-15 Roland Dreier <rdreier@cisco.com>
402 * include/infiniband/verbs.h: Document that devices must be opened
403 before calling ibv_free_device_list().
405 * src/verbs.c (ibv_create_srq): Not all provider libraries will
406 support SRQs, so check if the create_srq method is defined before
407 calling it. (Based on a patch from Shirley Ma <xma@us.ibm.com>)
409 2005-11-11 Roland Dreier <roland@cisco.com>
411 * examples/asyncwatch.c, examples/rc_pingpong.c,
412 examples/srq_pingpong.c, examples/uc_pingpong.c,
413 examples/ud_pingpong.c, examples/device_list.c,
414 examples/devinfo.c: Update examples to match new API.
416 * include/infiniband/verbs.h, src/device.c, src/init.c,
417 src/ibverbs.h: Change from dlist-based ibv_get_devices() API to
418 simpler ibv_get_device_list() and ibv_free_device_list() API.
420 2005-11-10 Sean Hefty <sean.hefty@intel.com>
422 * include/infiniband/sa-kern-abi.h: New include file to contain
423 definitions of SA structures passed between userspace and kernel.
425 * include/infiniband/sa.h: New include file for definitions of
426 SA structures used by multiple libraries.
428 * include/infiniband/marshall.h src/marshall.c: New files to define
429 routines used to exchange data with kernel modules.
431 * include/infiniband/kern-abi.h: Added data structures used to exchange
432 QP attribute with kernel modules.
434 2005-11-09 Michael S. Tsirkin <mst@mellanox.co.il>
436 * src/device.c (ibv_get_devices): Make function reentrant by using
437 a mutex to make sure we initialize the device list at most once.
439 2005-11-08 Roland Dreier <roland@cisco.com>
441 * src/cmd.c (ibv_cmd_create_qp): Add handling for new create QP
442 interface, which has the kernel return QP capabilities.
444 * src/cmd.c (ibv_cmd_modify_srq): Split off handling of modify SRQ
445 for ABI versions 3 and older, which passed max_sge as part of command.
447 2005-10-30 Roland Dreier <roland@cisco.com>
449 * examples/srq_pingpong.c (pp_init_ctx): Create CQ with rx_depth +
450 num_qp entries, instead of just rx_depth + 1 entries, because
451 there can be one send completion pending for each QP.
453 2005-10-25 Roland Dreier <roland@cisco.com>
455 * Release version 1.0-rc4.
457 * examples/uc_pingpong.c (pp_connect_ctx): Fix QP attribute masks
458 used to modify QP to RTR and RTS -- we should not be setting
459 RDMA/atomic attributes for UC QPs. Now that the mthca kernel
460 driver bug is fixed, the error is exposed here.
462 * examples/rc_pingpong.c, examples/srq_pingpong.c,
463 examples/uc_pingpong.c, examples/ud_pingpong.c: Keep track of
464 whether send and/or receive is pending. This avoids failures when
465 the remote side receives data and posts a send very quickly, and
466 the local side completes the receive before the previous send.
467 With the old code, this could result in posting a send before the
468 previous send completed, and therefore overrun the send queue.
470 2005-10-23 Roland Dreier <roland@cisco.com>
472 * src/cmd.c (ibv_cmd_get_context_v2): Correct silly mistake in
473 computation of size of buffer for old ABI command: we need to use
474 sizeof *cmd instead of sizeof cmd, since cmd is a pointer.
476 2005-10-21 Roland Dreier <roland@cisco.com>
478 * src/cmd.c (ibv_cmd_post_send, ibv_cmd_post_recv,
479 ibv_cmd_post_srq_recv): Correct value that we check write() return
480 value against so that we check against the size we actually try to
481 write, instead of just sizeof cmd.
483 2005-10-19 Roland Dreier <roland@cisco.com>
485 * src/cmd.c (ibv_cmd_req_notify_cq): Correct how we pass
486 solicited_only flag into the kernel.
488 2005-10-13 Roland Dreier <roland@cisco.com>
490 * include/infiniband/driver.h, src/cmd.c, src/libibverbs.map: Add
491 command functions for calling new kernel commands.
493 * include/infiniband/verbs.h: Add qp_type to struct ibv_qp so that
494 we know when we're posting a send on a UD QP, and add kernel
495 handle member to struct ibv_ah so we can handle drivers that do
496 create AH and destroy AH operations in the kernel.
498 * include/infiniband/kern-abi.h: Add new command structures for
499 poll CQ, request notification for CQ, post send, post receive,
500 post SRQ receive, create AH and destroy AH commands. These will
501 be used by the PathScale userspace driver.
503 2005-10-12 Roland Dreier <roland@cisco.com>
505 * examples/srq_pingpong.c (main): Zero out unused entries in
506 my_dest array to avoid string overflows when we send to the other
509 2005-10-09 Roland Dreier <roland@cisco.com>
511 * examples/devinfo.c (print_hca_cap): Only print max_mr_size and
512 page_size_cap if verbose is set.
514 2005-10-05 Roland Dreier <roland@cisco.com>
516 * src/cmd.c (ibv_cmd_modify_srq): Add function for marshalling
519 2005-09-29 Roland Dreier <roland@cisco.com>
521 * examples/devinfo.c (print_hca_cap): Get rid of formatting of
522 firmware version in what should be device-independent code.
524 * include/infiniband/driver.h, include/infiniband/verbs.h,
525 src/cmd.c (ibv_cmd_query_device): Change firmware version in
526 struct ibv_device_attr to be a string formatted by device-specific
529 2005-09-25 Roland Dreier <roland@cisco.com>
531 * examples/rc_pingpong.c, examples/srq_pingpong.c,
532 examples/uc_pingpong.c, examples/ud_pingpong.c: Update to match
533 new completion channel and CQ creation API.
535 * include/infiniband/driver.h, include/infiniband/verbs.h,
536 src/device.c, src/ibverbs.h, src/verbs.c, src/cmd.c: Add notion of
537 "completion channel" that allows consumers to dynamically create
538 and destroy file descriptors for retrieving completion events.
539 Completion channels are handled natively with kernel ABI version 3
540 and simulated with backwards compatibility implementations for ABI
543 * include/infiniband/kern-abi.h: Update to match kernel ABI

548 * src/device.c (ibv_get_device_guid): Use htonll() instead of
549 relying on pointer aliasing (which seems to break for some gcc
552 * include/infiniband/arch.h: Add htonll() and ntohll() functions.

556 * include/infiniband/kern-abi.h, include/infiniband/verbs.h,
557 src/cmd.c, src/device.c, src/verbs.c, examples/asyncwatch.c:
558 Update to handle new kernel ABI for avoiding stale completion
559 events. This is completely analogous to the previous asynchronous

565 src/cmd.c, src/device.c, src/ibverbs.h, src/init.c, src/verbs.c,
566 examples/asyncwatch.c: Update to handle new kernel ABI for
567 avoiding stale asynchronous events. When a CQ, QP or SRQ is
568 destroyed, the kernel reports the number of events it has given to
569 userspace, and we wait until we've handled the same number of
572 This does introduce a library API change: consumers are now
573 required to call ibv_put_async_event() to release every
574 asynchronous event that they retrieve via ibv_get_async_event().
