| 2565 constructor execution isn't messed with, nor timeslicing nor | |
| 2566 priority inheritance. | |

| 2572 slow down nightly testing for simulator platforms too much. | |
| 2573 (perform_stressful_tasks): added writing of a bit pattern to the | |
| 2574 malloc()-ed spaces. Also reduced stack requirements for threads. | |

| 2669 Generally: thread->to_queue_head() moves a thread to the head of | |
| 2670 whatever queue it is on, if relevant. This is so that a thread | |
| 2671 can change priority and then put itself at the front of its new | |
| 2672 run queue instead of the end; otherwise it yields too, which may | |

| 3751 1998-10-09 Hugo Tyson <hmt@cygnus.co.uk> | |
| 3752 | |
| 3753 * src/common/thread.cxx: | |
| 3754 clear_timer() is a static which always affects the executing | |
| 3755 thread and none other. Removed the "foo->" from various | |
| 3756 "foo->clear_timer()" calls to make this less confusing. | |
| 3757 Ditto set_timer(). | |
| 3758 Changed a "clear_timer()" call to "timer.disable()" and added one | |
| 3759 so that they affect _this_ thread, the thread which is being | |
| 3760 kill()ed or reinitialize()d rather than the killer or the | |
| 3761 resuscitator. Otherwise the alarm list can still get a loop in | |
| 3762 it when a thread's killed when waiting with a timeout and | |
| 3763 restarted soon enough. | |
| 3764 | |
| 3765 1998-10-08 Hugo Tyson <hmt@cygnus.co.uk> | |
| 3766 | |
| 3767 In general, these changes are to support create/delete of uITRON | |
| 3768 objects; this requires that an object can be destroyed whilst | |
| 3769 there are threads waiting on it, and that they shall be awoken | |
| 3770 with a specific return code. | |
| 3771 | |
| 3772 * include/thread.hxx: | |
| 3773 Cyg_Thread::DESTRUCT added to wake reasons, to deal with an object | |
| 3774 being destroyed whilst a thread is waiting on it; it's handled in | |
| 3775 a manner very similar to release() and BREAK wake_reason. | |
| 3776 | |
| 3777 * src/common/thread.cxx: | |
| 3778 thread_entry(): threads now exit() if the entry_point returns. | |
| 3779 Cyg_Thread() constructors now initialize wake_reason to NONE. | |
| 3780 reinitialize() clears any pending timeout before calling | |
| 3781 constructors. | |
| 3782 counted_sleep( [timeout] ) now both deal with the wake reason in | |
| 3783 general, and with DESTRUCT in particular. | |
| 3784 exit() now clears any pending timeout. | |
| 3785 kill() now force_resumes the thread first. | |
| 3786 kill() now does not explicitly remove the thread from any queue | |
| 3787 it's on; wake() does that for you anyway. | |
| 3788 delay() clears the timer just in case and handles DESTRUCT | |
| 3789 properly. | |
| 3790 DESTRUCT added to various switches for completeness. | |
| 3791 | |
| 3792 The fixes to counted_sleep()[x2] and kill() are a bugfix for | |
| 3793 PR#17688. | |
| 3794 | |
| 3795 * include/flag.hxx: | |
| 3796 * src/sync/flag.cxx: | |
| 3797 Add an argument, defaulting to 0, to the constructor which sets | |
| 3798 the initial flag value. | |
| 3799 Add handing of DESTRUCT wake reason. | |
| 3800 Add a destructor which wakes all threads with DESTRUCT | |
| 3801 wake_reason. | |
| 3802 | |
| 3803 * include/mboxt2.inl: | |
| 3804 Add handing of DESTRUCT wake reason. | |
| 3805 Add a destructor which wakes all threads with DESTRUCT | |
| 3806 wake_reason. | |
| 3807 | |
| 3808 * src/sync/cnt_sem2.cxx: | |
| 3809 Add handing of DESTRUCT wake reason. | |
| 3810 Add a destructor which wakes all threads with DESTRUCT | |
| 3811 wake_reason. | |
| 3812 Correct typo in logic for queueing a waiting thread in | |
| 3813 Cyg_Counting_Semaphore2::wait( cyg_tick_count abs_timeout ). | |
| 3814 This is a bugfix for PR#17687. | |

| 4219 requiring a bit of poking around for the variable block allocator. | |
| 4220 | |
| 4221 This is required for the C library realloc() implementation. Strictly | |
| 4222 this only uses the variable block allocator, but the API can only be | |
| 4223 enhanced by also updating the template. As a result, this also meant | |
| 4224 doing it for the fixed block allocator. | |

| 4295 tests/thread0.cxx, tests/thread1.cxx, tests/thread2.cxx: | |
| 4296 Change entry points from main() to cyg_start(), and remove return | |
| 4297 codes - while main returned an int, cyg_start() returns void. It has | |
| 4298 no meaning anyway - what could you do with the code? | |
| 4299 | |
| 4300 * src/test/tsttracc.c, src/test/tsttrace.cxx: | |
| 4301 Also change trace calls (CYG_REPORT_...) to reflect that it is a | |
| 4302 function called cyg_start with no args returning void, rather than | |
| 4303 what it was for main(argc, argv) | |
| 4304 | |
| 4305 Fri Aug 28 09:24:41 1998 Jesper Skov <jskov@cygnus.co.uk> | |
| 4306 | |
| 4307 * src/debug/generic-stub.c: Moved strcpy/strlen from hal-stub to | |
| 4308 generic-stub. Cleaned up a bit to avoid compiler warnings. | |
| 4309 | |
| 4310 Thu Aug 27 19:22:51 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 4311 | |
| 4312 * tests/kphilo.c (Philosopher): | |
| 4313 * tests/philo.cxx (Philosopher): | |
| 4314 * src/test/philo.cxx (Philosopher): | |
| 4315 * src/test/kphilo.c (Philosopher): | |
| 4316 * src/common/kapi.cxx: | |
| 4317 Change CYG_RELEASE_DEBUG to CYGPKG_INFRA_DEBUG. | |
| 4318 These changes are self-contained, so they can go in right now. | |
| 4319 | |
| 4320 Thu Aug 27 15:20:31 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 4321 | |
| 4322 * include/mvarimpl.inl (free): | |
| 4323 Remove a couple of warning due to pointer comparison without casts | |
| 4324 in coallesce(sic.) code. | |
| 4325 | |
| 4326 1998-08-26 Nick Garnett <nickg@cygnus.co.uk> | |
| 4327 | |
| 4328 * include/kapidata.h: | |
| 4329 Added saved_context to cyg_hardwarethread structure to track | |
| 4330 GDB support in rest of kernel. | |
| 4331 | |
| 4332 1998-08-25 Nick Garnett <nickg@cygnus.co.uk> | |
| 4333 | |
| 4334 * include/pkgconf/kernel.h: | |
| 4335 Added CYGIMP_KERNEL_THREAD_GDB_SUPPORT to configure for GDB | |
| 4336 interactions with the kernel. | |
| 4337 | |
| 4338 * src/debug/dbg-threads-api.h: | |
| 4339 * src/debug/dbg_gdb.cxx: | |
| 4340 Added these files to repository to support GDB interactions | |
| 4341 with the kernel. Note that dbg-threads-api.h is a copy of a | |
| 4342 file in devo/libstub. Any changes there must be merged in here | |
| 4343 too. | |
| 4344 | |
| 4345 * src/PKGconf.mak: | |
| 4346 Added debug/dbg_gdb.cxx to COMPILE list. | |
| 4347 | |
| 4348 * include/thread.inl: | |
| 4349 * include/thread.hxx: | |
| 4350 Added support for GDB, specifically for thread-aware debugging. | |
| 4351 | |
| 4352 * include/intr.hxx: | |
| 4353 * src/intr/intr.cxx: | |
| 4354 Added an extra argument to interrupt_end(): a pointer to | |
| 4355 the saved register state. This is optionally used to provide | |
| 4356 a more interesting saved register state for GDB. | |
| 4357 | |
| 4358 Tue Aug 25 02:36:26 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4359 | |
| 4360 * include/generic-stub.h: | |
| 4361 Add void to empty prototype argument lists to silence compiler | |
| 4362 warnings | |
| 4363 | |
| 4364 Fri Aug 21 18:46:34 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 4365 | |
| 4366 * src/common/clock.cxx (enable): | |
| 4367 Make the maths work right if we only just set up the clock | |
| 4368 thingy. Unsigned has a lot to answer for; when the next scheduled | |
| 4369 tick was all correct, the delta was -1, which correctly rounds to | |
| 4370 zero in the division. But it isn't -1 it's 18446744073709551615 | |
| 4371 which gave a shift of 15 in the the uITRON test programs. | |
| 4372 | |
| 4373 Fri Aug 21 11:40:50 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 4374 | |
| 4375 * include/mboxt2.inl (put): | |
| 4376 * include/mempolt2.inl (alloc): | |
| 4377 Tidy Nick's changes (1998-07-27) for set_timer() semantics a bit, | |
| 4378 make it a bit more efficient and smaller code. | |
| 4379 | |
| 4380 Thu Aug 20 17:37:35 BST 1998 Chris Provenzano <proven@cygnus.com> | |
| 4381 | |
| 4382 * include/mvarimpl.inl, include/pkgconf/kernel.h: | |
| 4383 Added memory coallecsing to the variable size memory allocator. | |
| 4384 This option is enabled my default. | |
| 4385 | |
| 4386 * tests/stdlib/malloc2.c: Only print 50 messages, not 500. | |
| 4387 | |
| 4388 1998-08-20 Nick Garnett <nickg@cygnus.co.uk> | |
| 4389 | |
| 4390 * include/pkgconf/kernel.h: | |
| 4391 Moved definition of CYG_KERNEL_USE_INIT_PRIORITY from here | |
| 4392 to hal.h. | |
| 4393 | |
| 4394 * include/thread.hxx: | |
| 4395 Changed argument to cyg_thread_entry() to CYG_ADDRWORD from | |
| 4396 CYG_ADDRESS. | |
| 4397 | |
| 4398 * include/ktypes.h: | |
| 4399 Moved constructor priority ordering stuff out to infra/cyg_type.h. | |
| 4400 | |
| 4401 * include/kapi.h: | |
| 4402 * src/common/kapi.cxx: | |
| 4403 Added name and priority parameters to cyg_thread_create() and | |
| 4404 swapped stack size and base parameters. These changes are | |
| 4405 currently protected by DAY_OF_CHAOS ifdefs and are therefore | |
| 4406 inactive. | |
| 4407 | |
| 4408 Wed Aug 19 19:06:16 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4409 | |
| 4410 * tests/bin_sem1.cxx, tests/bin_sem2.cxx, tests/cnt_sem1.cxx, | |
| 4411 tests/flag1.cxx, tests/mbox1.cxx, tests/memfix2.cxx, | |
| 4412 tests/memvar2.cxx, tests/sync2.cxx, tests/sync3.cxx, | |
| 4413 tests/thread2.cxx, tests/release.cxx, tests/kill.cxx: | |
| 4414 Reorder inclusion of thread.inl to silence warnings | |
| 4415 | |
| 4416 Wed Aug 19 18:48:03 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4417 | |
| 4418 * include/kernel.hxx: | |
| 4419 Reorder inclusion of thread.inl to silence warnings | |
| 4420 | |
| 4421 Wed Aug 19 18:21:31 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4422 | |
| 4423 * src/common/kapi.cxx, src/sync/flag.cxx: | |
| 4424 Reorder inclusion of thread.inl to silence warnings | |
| 4425 | |
| 4426 * src/sync/bin_sem.cxx, src/sync/cnt_sem.cxx, src/sync/cnt_sem2.cxx, | |
| 4427 src/sync/mbox.cxx: | |
| 4428 Add inclusion of thread.inl to silence warnings | |
| 4429 | |
| 4430 * src/common/memset.c: | |
| 4431 Make pointer arithmetic be on char *, not void * to silence warnings | |
| 4432 | |
| 4433 * include/diag.h, src/trace/diag.c: | |
| 4434 Make diag_init take void parameter, and give diag_printf explicit | |
| 4435 parameters in prototypes to silence warnings | |
| 4436 | |
| 4437 1998-08-19 Nick Garnett <nickg@cygnus.co.uk> | |
| 4438 | |
| 4439 * include/pkgconf/kernel.h: | |
| 4440 * src/common/thread.cxx: | |
| 4441 Added ifdef for CYGIMP_IDLE_THREAD_YIELD to support single | |
| 4442 priority configurations. | |
| 4443 | |
| 4444 Tue Aug 18 16:56:38 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4445 | |
| 4446 * include/thread.hxx, include/thread.inl: | |
| 4447 To silence compiler warnings, move register_exception inline definition | |
| 4448 from the .hxx to the .inl. Also move attach_stack to before the | |
| 4449 constructor where it is invoked from. | |
| 4450 | |
| 4451 1998-08-18 Nick Garnett <nickg@cygnus.co.uk> | |
| 4452 | |
| 4453 * include/pkgconf/kernel.h: | |
| 4454 Moved all HAL specific config options out to a HAL config file. | |
| 4455 | |
| 4456 * include/kapi.h: | |
| 4457 * src/common/kapi.cxx: | |
| 4458 Added cyg_scheduler_lock() and cyg_scheduler_unlock() to provide | |
| 4459 user access to the scheduler lock. | |
| 4460 | |
| 4461 Mon Aug 17 21:39:20 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4462 | |
| 4463 * include/kapi.h: | |
| 4464 Insert "void" to empty parameter lists to silence warnings | |
| 4465 | |
| 4466 Fri Aug 14 18:10:20 1998 Hugo Tyson <hmt@masala.cygnus.co.uk> | |
| 4467 | |
| 4468 * src/common/thread.cxx (exit): | |
| 4469 Set the state explicitly to EXITED rather than or'ing | |
| 4470 it in; should be safe cos it's what kill does in the normal case. | |
| 4471 Needed to avoid suspend sort of states persisting after death. | |
| 4472 One character changes are always aesthetically pleasing. | |
| 4473 | |
| 4474 Fri Aug 14 17:28:01 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 4475 | |
| 4476 * include/pkgconf/kernel.h: | |
| 4477 Add config options as below: | |
| 4478 | |
| 4479 * src/common/thread.cxx: | |
| 4480 Add asserts of CYGNUM_KERNEL_MAX_COUNTED_WAKE_COUNT_ASSERT | |
| 4481 and CYGNUM_KERNEL_MAX_SUSPEND_COUNT_ASSERT if they are defined. | |
| 4482 Also lazily tidied format of func hdrs as per code review et al. | |
| 4483 | |
| 4484 1998-08-14 Nick Garnett <nickg@cygnus.co.uk> | |
| 4485 | |
| 4486 * include/kapidata.h: | |
| 4487 Added support for thread names and thread housekeeping list. | |
| 4488 | |
| 4489 * src/common/delete.cxx: | |
| 4490 Added include for cyg_type.h. | |
| 4491 | |
| 4492 * include/pkgconf/kernel.h: | |
| 4493 Added CYGIMP_THREAD_NAME and CYGIMP_THREAD_LIST options. | |
| 4494 | |
| 4495 * include/thread.inl: | |
| 4496 * include/thread.hxx: | |
| 4497 Added support for thread names and thread housekeeping list. | |
| 4498 | |
| 4499 * src/common/thread.cxx: | |
| 4500 Added support for thread names and thread housekeeping list. | |
| 4501 Fixed ordering bug in Cyg_Thread::delay(). | |
| 4502 | |
| 4503 Thu Aug 13 15:33:48 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4504 | |
| 4505 * include/ktypes.h: | |
| 4506 Remove inlined new and delete as they aren't strictly permitted and | |
| 4507 they prevent a valid new and delete being defined anywhere else! | |
| 4508 | |
| 4509 * src/common/delete.cxx, src/PKGconf.mak: | |
| 4510 Add delete.cxx to provide default delete operation for when a C | |
| 4511 library isn't present | |
| 4512 | |
| 4513 1998-07-28 Nick Garnett <nickg@cygnus.co.uk> | |
| 4514 | |
| 4515 * include/thread.hxx, include/sched.hxx, include/mlqueue.hxx, | |
| 4516 include/lottery.hxx, include/bitmap.hxx, src/common/thread.cxx, | |
| 4517 src/sched/sched.cxx, src/sched/mlqueue.cxx, src/sched/lottery.cxx, | |
| 4518 src/sched/bitmap.cxx: | |
| 4519 Added an alternative constructor to Cyg_Thread which takes | |
| 4520 arguments in new order, and includes a scheduling parameters | |
| 4521 argument. Propagated effects of this through Cyg_SchedThread | |
| 4522 and Cyg_SchedThread_Implementation. This mostly takes the form | |
| 4523 of passing the scheduling parameters through to the constructors. | |
| 4524 | |
| 4525 1998-07-27 Nick Garnett <nickg@cygnus.co.uk> | |
| 4526 | |
| 4527 * src/sync/flag.cxx, src/sync/cnt_sem2.cxx, include/mempoolt.inl, | |
| 4528 include/mempolt2.inl, include/mboxt2.inl, include/mboxt.inl: | |
| 4529 Modified code in API calls that take a timeout to allow for a | |
| 4530 timeout in the past. | |
| 4531 NOTE: The timeouts have for now been left as relative delays, they | |
| 4532 should be converted to absolute timeouts. | |
| 4533 | |
| 4534 * src/common/thread.cxx: | |
| 4535 Modified code in counted_sleep to allow for a timeout in the past. | |
| 4536 Added handling of EXIT wake_reason in delay(). | |
| 4537 | |
| 4538 1998-07-24 Nick Garnett <nickg@cygnus.co.uk> | |
| 4539 | |
| 4540 * include/thread.inl: | |
| 4541 Reordered code in Cyg_Thread::set_timer() to init the timer after | |
| 4542 wake_reason has been assigned. | |
| 4543 | |
| 4544 * include/clock.inl: | |
| 4545 Removed Cyg_Alarm::enable(). | |
| 4546 | |
| 4547 * src/sync/mutex.cxx (Cyg_Condition_Variable::wait): | |
| 4548 Modified order of code in timed version of wait to allow for a | |
| 4549 timout in the past. | |
| 4550 | |
| 4551 * src/sync/cnt_sem.cxx (Cyg_Counting_Semaphore::wait): | |
| 4552 Modified order of code in timed version of wait to allow for a | |
| 4553 timout in the past. Also modified timeout to be absolute rather | |
| 4554 than relative. | |
| 4555 | |
| 4556 * src/common/thread.cxx (Cyg_Thread::wake): | |
| 4557 Added test for whether a thread is actually asleep before waking | |
| 4558 it. Allows us to apply wake() to awake threads without damage. | |
| 4559 | |
| 4560 * src/common/clock.cxx: | |
| 4561 Added code to Cyg_Counter::add_alarm() to deal with alarms | |
| 4562 that trigger now or in the past. | |
| 4563 Moved Cyg_Alarm::enable() here. Added code to do the right thing | |
| 4564 when reenabling previously disabled interval alarms. | |
| 4565 | |
| 4566 1998-07-23 Nick Garnett <nickg@cygnus.co.uk> | |
| 4567 | |
| 4568 * src/debug/stubrom.c: Added header comments. | |
| 4569 | |
| 4570 Thu Mar 26 18:25:36 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4571 | |
| 4572 * src/test/philo.cxx: | |
| 4573 Rename CYG_DEBUG ifdef to CYG_RELEASE_DEBUG | |
| 4574 | |
| 4575 Wed Mar 25 23:23:39 GMT 1998 Chris Provenzano <proven@cygnus.com> | |
| 4576 | |
| 4577 * configure.in: Fix so non_arch.h is updated even if | |
| 4578 config.cache does exists. | |
| 4579 | |
| 4580 * include/kapi.h, include/kapidata.h, include/kernel.hxx | |
| 4581 * include/mboxt.inl, include/sched.hxx: | |
| 4582 #include <eccconf/kernel.h> instead of include <eccconf/kernel.h> | |
| 4583 | |
| 4584 * include/eccconf/kernel.h: Added. This was old devo/config.h | |
| 4585 | |
| 4586 * src/Makefile.am : Set CYG_CONFIGURATION to "<eccconf/kernel.h>" | |
| 4587 | |
| 4588 * src/test/Makefile.am : Build .gdbinit from gdbinit.in | |
| 4589 and tree from tree.in | |
| 4590 | |
| 4591 Wed Mar 25 18:24:48 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 4592 | |
| 4593 * src/Makefile.am, src/common/memcpy.c, src/common/memset.c: | |
| 4594 Move memcpy and memset functions from C library into kernel to | |
| 4595 satisfy the requirements of gcc - namely it must be available at | |
| 4596 at all time. Changed memcpy and memset to sit more cleanly in the | |
| 4597 kernel, and lose all dependencies on the C library | |
| 4598 * src/Makefile.in: regenerated | |
| 4599 | |
| 4600 Fri Mar 13 18:36:42 GMT 1998 Chris Provenzano <proven@cygnus.com> | |

| 4608 Add support for the mn103000 | |
| 4609 | |
| 4610 Thu Mar 12 11:38:28 GMT 1998 David Moore <dsm@cygnus.co.uk> | |
| 4611 | |
| 4612 * src/Makefile.am: | |
| 4613 Removed flag to leave comments in generated linker script. | |
| 4614 | |
| 4615 Thu Mar 12 10:55:20 GMT 1998 David Moore <dsm@cygnus.co.uk> | |
| 4616 | |
