* include/Makefile.am: Updated to reflect files merged into newlib.
This resulted in some definitions moving to other files and thus
some secondary effects in RTEMS source code.
* include/unistd.h: Removed. Now use newlib's.
* include/rtems/posix/mqueue.h: Add include of <signal.h>.
* include/rtems/posix/threadsup.h: Add include of <sys/signal.h>
* src/execv.c: Corrected prototype to agree with newlib.
* src/execve.c: Corrected prototype to agree with newlib.
* src/execvp.c: Corrected prototype to agree with newlib.
* src/psignal.c: Rewrote reference to <siginfo.h> in comment since
that file no longer exists.
* src/pthreadkill.c: Added include of <signal.h>.
* src/sigaction.c: Added include of <signal.h>.
* src/sigtimedwait.c: Rewrote reference to <siginfo.h> in comment since
that file no longer exists.
*
* inline/rtems/posix/timer.inl, include/rtems/posix/timer.h,
inline/rtems/posix/Makefile.am, src/ptimer1.c: Redid the
style of src/ptimer1.c. Continued effort to make the
POSIX Timer implementation match that of other managers.
Added data structures required to use SuperCore Object Handler.
a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.
where alarm() did not correctly account for the watchdog start_time
and stop_time fields being based on ticks not seconds. This resulted
in alarm() returning a bogus number of seconds remaining.
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860
that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)
blocking sends when the queue is full. The SuperCore was enhanced
to support blocking on send. The existing POSIX API was debugged
and numerous test cases were added to psxmsgq01 by Jennifer Averett.
SuperCore enhancements and resulting modifications to other APIs
were done by Joel.
There is one significant point of interpretation for the POSIX API.
What happens to threads already blocked on a message queue when the
mode of that same message queue is changed from blocking to non-blocking?
We decided to unblock all waiting tasks with an EAGAIN error just
as if a non-blocking version of the same operation had returned
unsatisfied. This case is not discussed in the POSIX standard and
other implementations may have chosen differently.
power binary/mutex style semaphores already supported by RTEMS. This
was done at the request of Eric Norum <eric@cls.usask.ca> in support
of his effort to port EPICS to RTEMS. This change consisted of
changing the nesting_allowed boolean into a lock_nesting_behavior
enumerated value as well as allowing the core mutex object to optionally
support ensuring that the holder of a binary semaphore released it.
Finally, a more subtle enhancement was to allow the non-holder to release
a priority inheritance/ceiling mutex and still allow the holding task
to return to its original priority.
