|
* Mega patch merge to change the format of the object IDs to
|
| 35 |
|
|
loosen the dependency between the SCORE and the various APIs.
|
| 36 |
|
|
There was considerable work to simplify the object name management
|
| 37 |
|
|
and it appears that the name_table field is no longer needed.
|
| 38 |
|
|
This patch also includes the addition of the internal mutex
|
| 39 |
|
|
which is currently only used to protect some types of allocation
|
| 40 |
|
|
and deallocation. This significantly can reduce context
|
| 41 |
|
|
switch latency under certain circumstances. In particular,
|
| 42 |
|
|
some heap/region operations were O(n) and had dispatching
|
| 43 |
|
|
disabled. This should help enormously. With this merge,
|
| 44 |
|
|
the patch is not as clean as it should be. In particular,
|
| 45 |
|
|
the documentation has not been modified to reflect the new object
|
| 46 |
|
|
ID layout, the IDs in the test screens are not updated, and
|
| 47 |
|
|
_Objects_Get_information needs to be a real routine not inlined.
|
| 48 |
|
|
As part of this patch a lot of MP code for thread/proxy blocking
|
| 49 |
|
|
was made conditional and cleaned up.

* include/rtems/score/thread.h, inline/rtems/score/thread.inl,

src/threaddispatch.c, src/threadinitialize.c:
|
| 72 |
|
|
Move the C library re-enterrant support directly into
|
| 73 |
|
|
the thread dispatch code. RTEMS needs libc and so requiring
|
| 74 |
|
|
libc to use a user extension with its overhead is not the best
|
| 75 |
|
|
solution. This patch lowers the overhead to 2 pointer moves.

|
|
|
| 84 |
|
|
* src/threaddispatch.c, src/threadhandler.c: Per PR211 fix
|
| 85 |
|
|
saving/restoring floating point context. The fpsave and fprestore
|
| 86 |
|
|
routines are only used in a executing context which _is_ fp and hence
|
| 87 |
|
|
has the FPU enabled. The current behavior required the FPU always to
|
| 88 |
|
|
be on which is very dangerous if lazy context switching is used.
|
| 89 |
|
|
[Joel Note: Some ports explicitly enabled the FPU in the FP save and
|
| 90 |
|
|
restore routines to avoid this.]
|
| 91 |
|
|
|
| 92 |
|
|
The patch also makes sure (on powerpc only) that the FPU is disabled
|
| 93 |
|
|
for integer tasks. Note that this is crucial if deferred fp context
|
| 94 |
|
|
switching is used. Otherwise, fp context corruption may go undetected!
|
| 95 |
|
|
Also note that even tasks which merely push/pop FP registers to/from
|
| 96 |
|
|
the stack without modifying them still MUST be FP tasks - otherwise
|
| 97 |
|
|
(if lazy FP context switching is used), FP register corruption (of
|
| 98 |
|
|
other, FP, tasks may occur)!
|
| 99 |
|
|
|
| 100 |
|
|
Furthermore, (on PPC) by default, lazy FP context save/restore
|
| 101 |
|
|
is _disabled_.

|
|
* include/rtems/score/object.h, inline/rtems/score/object.inl,
|
| 110 |
|
|
src/objectcomparenamestring.c: Address PR81 that
|
| 111 |
|
|
reworked POSIX message queues to add a descriptor separate from
|
| 112 |
|
|
the underlying message queue. This allows non-blocking to follow
|
| 113 |
|
|
the "open" not the underlying queue. As part of debugging this
|
| 114 |
|
|
it became clear that _Objects_Compare_name_string was broken
|
| 115 |
|
|
and a simple version using strncmp() was substituted.

|
|
* src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c,
|
| 294 |
|
|
inline/rtems/score/coremutex.inl: The per thread field resource_count
|
| 295 |
|
|
should only be manipulated when a mutex is priority ceiling or
|
| 296 |
|
|
priority inherit. This was reported by Chris Johns
|
| 297 |
|
|
who also noticed that the use of switches for all disciplines
|
| 298 |
|
|
generated less efficient code than using explicit tests for the one
|
| 299 |
|
|
or two cases we were really interested in. Further review of his
|
| 300 |
|
|
modifications made it apparent that the "isa" methods to test mutex
|
| 301 |
|
|
discipline were not being used so this modification was swept into
|
| 302 |
|
|
the code as well.

2001-08-30 Joel Sherrill
|
| 305 |
|
|
|
| 306 |
|
|
* src/coremutexseize.c: Add missing code for proper handling
|
| 307 |
|
|
of nesting acquisitions. This only impacts building with
|
| 308 |
|
|
inlines disabled on the source with the "fast mutex" optimizations.
|
| 309 |
|
|
This was post the 4.5 branch and did not impact released versions.

| 312 |
|
|
|
| 313 |
|
|
* src/coremutexsurrender.c: Use holder thread not executing
|
| 314 |
|
|
thread because even though they may and often are the same
|
| 315 |
|
|
it is not guaranteed unless the proper attribute is set.

|
| 318 |
|
|
|
| 319 |
|
|
* include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new
|
| 320 |
|
|
return status to account for blocking sends. Otherwise, the
|
| 321 |
|
|
caller will think that the returned message status will have
|
| 322 |
|
|
the ultimate results of the operation. If the send times out,
|
| 323 |
|
|
the final status will be in the return_code of the thread.

|
|
* include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl,
|
| 328 |
|
|
src/coremsgsubmit.c: Unblocking message queue operations should
|
| 329 |
|
|
NOT use _Thread_Executing for return status since it is permissible
|
| 330 |
|
|
to invoke message send operations from an ISR. This was reported
|
| 331 |
|
|
by Suvrat Gupta .

inline/rtems/score/Makefile.am, macros/rtems/score/Makefile.am
|

eliminate warning.

warning removal patch. :(

|
| 367 |
|
|
now that it is dynamically allocated.
|
| 368 |

|
2000-12-19 Joel Sherrill
|
| 370 |
|
|
|
| 371 |
|
|
* src/isr.c: Allocate the _ISR_Vector_table all the time not just when
|
| 372 |
|
|
we are allocating an interrupt stack.

| 373 |
|

2000-12-13 Joel Sherrill
|
| 375 |
|
|
|
| 376 |
|
|
* include/rtems/score/isr.h, src/isr.c: Allocate it from the
|
| 377 |
|
|
workspace rather than explicitly declaring it. This allows
|
| 378 |
|
|
the size to be a non-constant from the perspective of score/cpu.
|
| 379 |

|
2000-12-01 Joel Sherrill
|
| 381 |
|
|
|
| 382 |
|
|
* macros/rtems/score/coresem.inl: Removed comments since convention
|
| 383 |
|
|
calls for comments to be in inline versin.
|
| 384 |
|
|
* macros/rtems/score/object.inl (Objects_Get_local_object): Fixed
|
| 385 |
|
|
style to use _ prefix on variable names and use parentheses.
|
| 386 |
|
|
* macros/rtems/score/object.inl (_Objects_Namespace_remove): Added.
|
| 387 |

|
|
|
| 390 |
|
|
* General effort to make things compile with macros not inlines
|
| 391 |
|
|
* inline/rtems/score/coremutex.inl: Added comment indicating
|
| 392 |
|
|
for macros there is another copy of
|
| 393 |
|
|
_CORE_mutex_Seize_interrupt_trylock() in src/coremutexseize.c.
|
| 394 |
|
|
* src/coremutexseize.c: Added body of
|
| 395 |
|
|
_CORE_mutex_Seize_interrupt_trylock() for macro case.
|
| 396 |
|
|
* macros/rtems/score/coremutex.inl: Added prototype for
|
| 397 |
|
|
_CORE_mutex_Seize_interrupt_trylock() since there is a real
|
| 398 |
|
|
body when macros are enabled.
|
| 399 |
|
|
* macros/rtems/score/coresem.inl: Added macro implementation of
|
| 400 |
|
|
_CORE_semaphore_Seize_isr_disable.
|
| 401 |
|
|
* macros/score/Makefile.am: Fixed typos.
|
| 402 |
|
|
* rtems/score/address.inl: Correct macro implementation of
|
| 403 |
|
|
_Addresses_Is_aligned() so it would compile.
|
| 404 |
|
|
* macros/rtems/score/coremsg.inl: Added closing parentheses.

2000-11-28 Chris Johns
|
| 407 |
|
|
|
| 408 |
|
|
* src/heapallocate.c: Do not allow the size to overflow when
|
| 409 |
|
|
adjusting it. A test allocated a stack of -1 (~0). This
|
| 410 |
|
|
actually resulted in a stack being allocated but with a
|
| 411 |
|
|
size of 0xb. The allocator did not test the size to see if
|
| 412 |
|
|
it rolled through 0 and so allowed the allocation to happen, the
|
| 413 |
|
|
thread to get created. The task crashed as you would expect.

|
2000-11-02 Joel Sherrill
|
| 416 |
|
|
|
| 417 |
|
|
* include/rtems/system.h: Use proper conditional (RTEMS_POSIX_API)
|
| 418 |
|
|
so prototypes for POSIX_MP_NOT_IMPLEMENTED(), POSIX_NOT_IMPLEMENTED(),
|
| 419 |
|
|
POSIX_BOTTOM_REACHED() are actually included.
|
| 420 |

|
2000-11-02 Joel Sherrill
|
| 422 |
|
|
|
| 423 |
|
|
* include/rtems/system.h: Add prototypes for POSIX_MP_NOT_IMPLEMENTED(),

|
|
POSIX_NOT_IMPLEMENTED(), POSIX_BOTTOM_REACHED() removed from newlib.

|
* rtems/system.h: Switched a29k and hppa1.1 to using cpuopts.h not
|
| 435 |
|

|
|
* Many files: Moved posix/include/rtems/posix/seterr.h to

| 450 |
|
