This is the list of outstanding problems in this release.
+ The m68000 support is not quite complete yet. The missing piece
inside the executive proper is support for the software interrupt
stack. Also, the m68k family has become quite large and an
understanding of the compatibility of the peripherals on the various
members of the 683xx family would allow someone to designate some
of the drivers submitted for the gen68302 BSP as useful on other
+ The only i960 family member tested is the CA. No support for the
floating point support found in other family members is present.
This also implies that RTEMS may "think" of something as generic
across the i960 family when in fact it is specific to the CA.
+ The __read() system call in all of the BSPs using single
character input/output needs to be smarter. The following
issues need to be addressed:
+ echoing of characters on input
+ CR/NL echoing
+ UNIX port notes:
+ Some of the tests run correctly when run interactively but
the screen and output do not match when the output is
redirected to a file.
+ sometimes a stray SIGALRM is reported as spfatal completes.
+ multiple BSPs need to be merged into a single source one.
+ CPU code appears to not set the interrupt level correctly
when doing a context initialization and sigsetjmp should be used.
+ General cleanup and reorganization to enhance portability.
+ Currently the routines which need to make access to the
native library (not newlib) are spread across a number of
directories. There should be a "unix_XYZ" wrapper for every
one of these routines so there is only 1 directory which directly
references the "real" native library.
+ Some of the tests may execute correctly and not produce the exact
ordering of lines in the screen file. This appears to be a combination
of a number of factors including buffering, processor speed, IO
device overhead, and clock interrupt rate.
+ The compiler configuration files (c/make/gcc-XYZ.cfg) are largely
the same when the different targets have the same CPU. It would
be desirable to have a gcc-CPU.cfg or gcc-CPU_MODEL.cfg (e.g.
gcc-m68k.cfg or gcc-m68020.cfg) and have the file gcc-TARGET.cfg
include this and possibly override default settings.
+ The clock device drivers should really avoid doing the division
by 1000 in the clock tick ISR to convert microseconds into
milliseconds. This only applies to clock drivers which generate
an ISR each millisecond and only call rtems_clock_tick every
so many ISRs.
+ The MP code for the Message Manager copies the message buffer
in and out of the MPCI packet at at least two unecessary times:
+ as part of some send requests
+ on a non-successful receive response
