| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Mega patch merge to change the format of the object IDs to loosen the dependency between the SCORE and the various APIs. There was considerable work to simplify the object name management and it appears that the name_table field is no longer needed. This patch also includes the addition of the internal mutex which is currently only used to protect some types of allocation and deallocation. This significantly can reduce context switch latency under certain circumstances. In particular, some heap/region operations were O(n) and had dispatching disabled. This should help enormously. With this merge, the patch is not as clean as it should be. In particular, the documentation has not been modified to reflect the new object ID layout, the IDs in the test screens are not updated, and _Objects_Get_information needs to be a real routine not inlined. As part of this patch a lot of MP code for thread/proxy blocking was made conditional and cleaned up. * include/Makefile.am, include/rtems/score/coremsg.h, include/rtems/score/coremutex.h, include/rtems/score/coresem.h, include/rtems/score/object.h, include/rtems/score/threadq.h, inline/rtems/score/object.inl, inline/rtems/score/thread.inl, macros/rtems/score/object.inl, src/Makefile.am, src/coremsg.c, src/coremutex.c, src/coresem.c, src/mpci.c, src/objectcomparenameraw.c, src/objectextendinformation.c, src/objectinitializeinformation.c, src/objectnametoid.c, src/thread.c, src/threadclose.c, src/threadget.c, src/threadq.c, src/threadqextractwithproxy.c: Modified as part of above. * include/rtems/score/apimutex.h, src/objectgetnoprotection.c: New files.

| | | | | * macros/rtems/score/thread..inl: Implemented missing routines for new libc reentrancy support.
* 2002-05-15 Chris Johns <ccj@acm.org>Joel Sherrill2002-05-151-0/+9
| | | | | | | | | * include/rtems/score/thread.h, inline/rtems/score/thread.inl, src/threaddispatch.c, src/threadinitialize.c: Move the C library re-enterrant support directly into the thread dispatch code. RTEMS needs libc and so requiring libc to use a user extension with its overhead is not the best solution. This patch lowers the overhead to 2 pointer moves.
* 2002-05-03 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-05-141-0/+5
| | | | | * include/Makefile.am: Work-around to autoconf-2.53 adding PACKAGE_* to autoheaders - sed out *PACKAGE* from cpuopts-tmp.h.
* 2001-05-14 Till Straumann <strauman@slac.stanford.edu>Joel Sherrill2002-05-141-0/+21
| | | | | | | | | | | | | | | | | | | | | * src/threaddispatch.c, src/threadhandler.c: Per PR211 fix saving/restoring floating point context. The fpsave and fprestore routines are only used in a executing context which _is_ fp and hence has the FPU enabled. The current behavior required the FPU always to be on which is very dangerous if lazy context switching is used. [Joel Note: Some ports explicitly enabled the FPU in the FP save and restore routines to avoid this.] The patch also makes sure (on powerpc only) that the FPU is disabled for integer tasks. Note that this is crucial if deferred fp context switching is used. Otherwise, fp context corruption may go undetected! Also note that even tasks which merely push/pop FP registers to/from the stack without modifying them still MUST be FP tasks - otherwise (if lazy FP context switching is used), FP register corruption (of other, FP, tasks may occur)! Furthermore, (on PPC) by default, lazy FP context save/restore is _disabled_.

| | | | * src/objectcomparenamestring.c: Fix typos.
* 2001-04-26 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2002-04-261-0/+10
| | | | | | | | | | * include/rtems/score/object.h, inline/rtems/score/object.inl, src/objectcomparenamestring.c: Address PR81 that reworked POSIX message queues to add a descriptor separate from the underlying message queue. This allows non-blocking to follow the "open" not the underlying queue. As part of debugging this it became clear that _Objects_Compare_name_string was broken and a simple version using strncmp() was substituted.
* 2002-04-18 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-04-181-0/+4
| | | | * include/rtems/system.h: Remove targopts.h.
* 2002-04-17 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-04-171-0/+5
| | | | | * include/rtems/system.h: Add the sparc to the target supporting multlibs.
* 2002-04-16 Chris Johns <ccj@acm.org>Joel Sherrill2002-04-161-0/+7
| | | | | | | * src/threadinitialize.c: Per PR181, clear the array of user extension pointers. This lets user extensions that have hooked the switch handler know if a task has been processed by the user extension before. If a user extension is created after a task is started it may not know it.
* 2002-04-12 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-04-121-0/+4
| | | | * include/rtems/system.h: Add i386 to multilib-able targets.
* 2001-04-11 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2002-04-111-0/+8
| | | | | | | * macros/rtems/score/userext.inl: Now works after merging patch for functionality requested in PR174. * inline/rtems/score/userext.inl: Added a comment explaining the order in which routines appear since it is not the obvious order.
* 2002-04-08 Chris Johns <ccj@acm.org>Joel Sherrill2002-04-091-0/+6
| | | | | | * Per PR141 and PR174, make task switch extension its own list and fix all odd problems introduced by providing macro version. * inline/rtems/score/userext.inl: Fix.
* 2001-04-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2002-04-081-0/+4
| | | | * macros/rtems/score/object.inl: Corrected arguments.
* 2001-04-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2002-04-081-0/+6
| | | | | | * macros/rtems/score/userext.inl: Updated to reflect modifications to inline version from PR142. * inline/rtems/score/userext.inl: Cleanup as side-effect of above.
* 2002-04-08 Chris Johns <ccj@acm.org>Joel Sherrill2002-04-081-0/+8
| | | | | | | | * Per PR142, make task switch extension its own list. * include/rtems/score/userext.h: Reflect above by adding User_extensions_Switch_control and adding it to User_extenions_Control. * inline/rtems/score/userext.inl: Allocate all memory in one chunk to minimize overhead. Address processing dedicated switch chain.

| | | | * include/rtems/score/watchdog.h: Added WATCHDOG_MAXIMUM_INTERVAL.
* 2002-01-19 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-01-201-0/+5
| | | | | * include/rtems/system.h: Fix typo in yesterday's change: RTEMS_MULTILIBS.
* 2001-01-18 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2002-01-181-0/+7
| | | | | | | * include/rtems/system.h: Only include cpuopts.h when building a multilib configuration. Some ports still need targopts.h but this small modification lets those ports work non-multilib while fixing being fixed for multilib.
* 2002-01-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2002-01-041-0/+6
| | | | | | * include/rtems/seterr.h: Add do {..} while (0) in defines. Rename set_errno_and_return_minus_one into rtems_set_errno_and_return_minus_one.
* 2001-12-19 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2001-12-201-0/+6
| | | | | | * inline/rtems/score/object.inl, macros/rtems/score/object.inl: Add add casts to Objects_Id in _Objects_Build_ids to avoid implicit typecasts from enum to int16 on bit16 targets (here: h8300).
* 2001-12-19 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2001-12-191-0/+4
| | | | * src/Makefile.am: Add multilib support.
* 2001-11-28 Joel Sherrill <joel@OARcorp.com>,Joel Sherrill2001-11-281-0/+9
| | | | | | | | | This was tracked as PR91. * include/rtems/score/isr.h, inline/rtems/score/isr.inl, macros/rtems/score/isr.inl: Modified to allow any port to provide its own implementation of the macro _ISR_Is_in_progress. If the port overrides this macro, it must provide a non-inlined function implementation.
* 2001-11-20 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-11-201-0/+8
| | | | | | | | * src/threadhandler.c: When __USE__MAIN__ is defined by the toolset, invoke the global constructors via __main. Reported as tested by Alexandra Kossovsky <sasha@oktet.ru> and Victor V. Vengerov <vvv@oktet.ru> in conjunction with a new set of tool RPMs (gcc2.95.3newlib1.9.0-3). This was tracked as GNATS PR tools/84.
* 2001-11-07 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-11-071-0/+8
| | | | | | | | | Reported by Todor.Todorov@barco.com and tracked as PR36. * include/rtems/score/object.h: Added prototype for _Objects_Get_by_index(). * src/objectget.c, src/objectgetisr.c: Corrected procedure for getting index from Id so it is correct and optimal for both single and multiprocessor configurations.
* 2001-10-22 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-10-221-0/+5
| | | | | * src/threadhandler.c: Use __USE_INIT_FINI__ since USE_INIT_FINI pollutes the application namespace.
* 2001-10-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-10-171-0/+4
| | | | * .cvsignore: Add stamp-h.in.
* 2001-10-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-10-171-0/+4
| | | | * include/Makefile.am: Fixed path to cpuopts-tmp.h.

| | | | | | | * include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='. * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
* 2001-09-27 Eric Norum <eric.norum@usask.ca>Joel Sherrill2001-09-271-0/+14
| | | | | | | * src/threadhandler.c: Now process C++ global constructors (_init) as part of the first task execution not in BSP space. This depends on the toolset defining USE_INIT_FINI so you have to have the right toolset version.
* 2001-08-30 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-08-301-0/+13
| | | | | | | | | | | | | * src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c, inline/rtems/score/coremutex.inl: The per thread field resource_count should only be manipulated when a mutex is priority ceiling or priority inherit. This was reported by Chris Johns <ccj@acm.org> who also noticed that the use of switches for all disciplines generated less efficient code than using explicit tests for the one or two cases we were really interested in. Further review of his modifications made it apparent that the "isa" methods to test mutex discipline were not being used so this modification was swept into the code as well.
* 2001-08-30 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-08-301-0/+7
| | | | | | | * src/coremutexseize.c: Add missing code for proper handling of nesting acquisitions. This only impacts building with inlines disabled on the source with the "fast mutex" optimizations. This was post the 4.5 branch and did not impact released versions.
* 2001-08-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-08-161-0/+6
| | | | | | * src/coremutexsurrender.c: Use holder thread not executing thread because even though they may and often are the same it is not guaranteed unless the proper attribute is set.
* 2001-08-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-08-161-0/+8
| | | | | | | | * include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new return status to account for blocking sends. Otherwise, the caller will think that the returned message status will have the ultimate results of the operation. If the send times out, the final status will be in the return_code of the thread.
* 2001-08-09 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-08-091-0/+8
| | | | | | | | * include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl, src/coremsgsubmit.c: Unblocking message queue operations should NOT use _Thread_Executing for return status since it is permissible to invoke message send operations from an ISR. This was reported by Suvrat Gupta <suvrat@utstar.com>.
* 2000-05-25 Sergei Organov <osv@javad.ru>Joel Sherrill2001-05-251-0/+6
| | | | | | * macros/rtems/score/coresem.inl, inline/rtems/score/coresem.inl: Cut and paste problem incorrectly enabled interrupts twice with the first time being too early.
* 2001-05-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2001-05-091-0/+5
| | | | | * include/rtems/score/.cvsignore: Add stamp-h, cpuopts.h, cpuopts.h.in, cpuopts-tmp.h.
* 2001-02-03 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2001-02-051-0/+6
| | | | | | * include/rtems/Makefile.am, include/rtems/score/Makefile.am, inline/rtems/score/Makefile.am, macros/rtems/score/Makefile.am Apply include_*HEADERS instead of H_FILES.
* 2001-01-29 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-01-291-0/+5
| | | | | * src/objectextendinformation.c: Added include of string.h to eliminate warning.
* 2001-01-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-01-081-0/+5
| | | | | * src/threadinitialize.c: Fix my bad hack of Ralf's fp_area warning removal patch. :(
* 2001-01-08 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2001-01-081-0/+4
| | | | * src/threadinitialize.c: Removed warning.
* 2001-01-03 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-01-031-0/+5
| | | | * rtems/score/cpu.h: Added _CPU_Initialize_vectors().
* 2000-12-19 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2000-12-191-0/+5
| | | | | * src/isr.c: Allocate the _ISR_Vector_table all the time not just when we are allocating an interrupt stack.
