- Subject: RTEMS 19990528 is Available
May 28, 1999
This is to announce the availability of RTEMS-19990528. There have been a
variety of changes. The most far reaching are those made by OAR
addressing the minimum application size.
I am sure there are things I have forgotten to merge or otherwise include
in this snapshot. Please let me know if there is anything missing and I
will take care of it.
I am very sure the the Outstanding Issues section has items in it which
should be considered closed. If you can let me drop something off this
list, please tell me it is closed to your satisfaction.
================================================================
I am keeping this as a running list of major enhancements for a
release notice. :)
Major functional enhancements since 4.0.0 include:
+ Addition of libchip
+ Addition of remote debug server
+ Multiprocessing is now a configure time option
+ Build tree now uses automake for native tools
+ Smaller Application Executables!!!
+ XON/XOFF flow control support added
+ mpc821 support added
+ i960HA support added
+ Addition of the following BSPs:
- Technologic Systems TS-1325 (i386ex) BSP
- DY-4 DMV177 (PPC603e) BSP
- eth_comm (mpc860) BSP
- Motorola MVME167 (68040) BSP
- Vista SCORE603e (PPC603e) BSP
- Radstone ppcn_60x (PPC603e) BSP
+ Addition of file system infrastructure
- In-Memory Filesystem
- TFTP Client Filesystem
+ Network functionality
- select() supported for socket
- DHCP support added
- "tap" functionality added
- timeout on sockets supported
- numerous network device drivers
+ GNAT/RTEMS
- Ada "self" optimized
- Ada interrupt support
================================================================
Outstanding issues:
+ m68k BSPs should be checked for .gcc_exc section like dmv152
+ TFTP Filesystem handling of bootp server.
+ TFTP driver/Filesystem needs to account for old handling of minor number.
+ A stripped down version of the IMFS should be used by default.
This should only require adding a new FS table with minimal entries.
+ i960 cvme961 does not link cdtest
+ Are the HID registers specific to the PPC603e?
+ ftpd in tree but not built (is this still true?)
+ no untar documentation (I think I have this but have not merged it)
+ no lstat test
+ no lstat documentation
+ no confdefs.h documentation
+ size script
+ ts_386ex BSP may not build
+ no acknowledgement for ts_386ex BSP
+ GNAT patches need to be updated
+ Ada examples collection needs to be released.
Are these fixed like I think?
+ configure should detect that a CPU does not yet support rdbg
+ configure should detect that rpcgen is not present
================================================================

================================================================
Status information for 19990331 (changes since 19990302):
Testing: More rigorous than 19990210. Most targets build.
Some warnings removed. Tests run on simulator.
Tools:
+ egcs-1.1.2-rtems-diff-19990331
- limits.h handling (Ian)
Documentation:
+ I have a queue of stuff to merge.
Code:
+ XON/XOFF flow control support (Thomas Doerfler)
+ m68k/rtems.S would not assemble for m68000 targets (Joel)
+ unlimited objects patch so sp09 gets the proper
error when attempting rtems_port_delete(0) (Chris)
+ NE2000 driver patch to add byte wide interface support (Tony Ambardar)
+ shutdown TCP/IP stack routine added (Tony Ambardar)

new maximum file length (difference between IMFS and global max).
Report from Emmanuel (Jennifer).

(Rosimildo DaSilva <rdasilva at connecttel.com>)
+ SONIC driver modifications to use new driver name parsing scheme (Eric N)
+ SONIC driver modifications after port to SPARC target (Jiri)
+ SPARC optimized IP checksum header routine (Jiri)
+ Changed driver name parsing scheme (Eric N)
+ much work from Ralf moving RTEMS toward automake. The aclocal
directory is more populated in anticipation of having more
localized configure scripts in the tree. RTEMS is now installed
at the top level of the tool tree instead of under the rtems/
subdirectory. This is another step in more closely following GNU
conventions. It is needed to help us use automake and ease the eventual
split of RTEMS into CPU and board dependent libraries. Pieces of the
various patches touch nearly every file in build system. It is
possible that something broke but Ralf has made very attempt to
be cautious. All native tool build directories are now
automaked. (Ralf)

level configure.in (Ralf)

+ messages changed for disable inlines (Chris)
+ efi332 update (John S. Gwynne)
+ added ftpd server (Jake)
+ lib/Makefile.in did not install rdbg header files (Emmanuel/Joel)
+ rdbg exception processing used wrong constant (Joel)
+ rdbg/Makefile.in accidentally put source in the library (Joel/Emmanuel)
+ i386ex netowrk driver bug fix (Erik I)
+ i386 interrupt handling macros patched (Eric V/Ian)
+ fdopen/fcntl(F_GETFL,F_SETFL) fix (Joel/Jake)
+ IMFS memfile bug for files (Joel/Jake)
+ Added $(CPPFLAGS) to all gcc 2.8 style make-exe rules. (Joel/Ralf)
+ psx04 had test case for ENOSYS and the code is not implemented (Jennifer)
+ SONIC ISR incorrectly installed as RAW handler (Jiri/Joel)

+ insure that a file description was actually open. This
error was in a lot of the system calls. (Ian/Joel)
