<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

Gauthier <charles.gauthier@nrc.ca>. The power supply in their
VMEbus cage died so it was submitted at this point. It passes ttcp
which is a really good sign but they would like to do more testing
and cleanup once their hardware is functional again. Please
contact them if you are interested in using or fixing this driver.
As their comments indicate, the performance is actually quite good
even at this point as indicated by the ttcp results.
Please note that this is by no means a final version. The code is still
fairly ugly, and will require some further fixing. On the bright side, what
is attached works. I finally ran the test programs successfully with
optimized code and data cache enabled:
netdemos worked, but failed on the UDP transfer (runs out of buffers).
ttcp worked, with something like 1036 KB/sec Rx, 952 KB/sec Tx.
tftp worked

Bob Wisdon <bobwis@ascweb.co.uk> and Chris Johns <ccj@acm.org>
to resolve a random network lockup problem.
ckinit.c:
Occasional network lockups have been noted when the PIT has a higher
interrupt request level than the CPM. The SCC1 bit in the CISR is set
even though the SCC1 interrupt handler is not active. This blocks
interrupts from SCC1 (and all other CPM sources) and locks up the
system. It has not been determined whether the error is within the
68360 or in the RTEMS interrupt support assembler code. The solution,
for now, is to set both PIT and CPM interrupt request levels to the same
value (4).
network.c:
Set CPM transmitter buffer pointer (_tbptr) to beginning of frame
before restarting transmitter. Don't retire transmitter buffer
descriptors belonging to the restarted frame.

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)

that contains the automake files for libnetworking plus a couple of
minor fixes. [Now only one unused/unsupported Makefile.in remains
(./c/src/lib/libbsp/hppa1.1/pxfl/Makefile.in).]
To apply:
patch -p1 < rtems-rc-20000118-7.diff
/bin/sh rtems-rc-20000118-7.rm
/bin/sh rtems-rc-20000118-7.add
./bootstrap
Notes:
* I have tested this one by building all BSPs for m68k, powerpc, sh and
unix with toolchains built since last weekend.
* I did not touch libnetworking's directory layout.

that contains:
* The fix for the gen68360/network/Makefile.am
* automatically set permissions to 755 to scripts/buildall and
scripts-ada/buildall (I remembered a trick to achieve this :).
* automake support for libbsp/* and libcpu/* (Attn: This part will
finally break old-style configuration for all non-public cpus)
NOTES:
* This patch has only been tested for a random selection of BSPs (I
haven't rebuilt all toolchains yet).
* This patch is against rtem-cvs as of this morning (MET).

Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain:
* Modifications, (minor) corrections, cleanups to most existing
Makefile.ams
* Adds automake support to all remaining BSPs which have not yet been
converted to automake.
* Makefile.am for all remaining wrapup/Makefile.ams
|
|
that contains:
* cleanups to configuration files
* A reworked gccnewlib.spec.in: I have reformated it for enhanced
readability and added more rtems-base packages. It now should be free of
any installation conflicts (If there still remain some, they should be
regarded as bugs).
* A fix to the bin2boot RTEMS_BSP issue (make RTEMS_BSP="pc386 pc486"
now works).
* removes libbsp/bare/wrapup
* Further cleanups

Some excellent sleuthing by Bob Wisdom <bobwis@ascweb.co.uk> revealed
that an empty mbuf at the end of a packet chain would cause the `retire'
function to blow up. Moving the line of code which bumps the transmit
buffer descriptor pointer fixes the problem. Some additional cleanup of
the sendpacket function was also completed.

for the gen68360 that let it work with ELF and C++ exceptions. This
was used as the basis for changes to EVERY m68k bsp_specs and linkcmds.
Before this modification is over, the layout of the starting stack,
heap, and workspace will likely be modified for every m68k BSP. Then
they will all be very similar.

that converts the libbsp/i386 subdirectory to full automake.
|

that fixes the following problems:
1. Removing bogus ';' in some configure.in (cosmetical fix)
2. Moves GAS_CODE16 checks to libbsp/i386/*/configure.in (essential fix)
#2 was responsible for the gcc/binutils-2.9.5 choking while building for
the pc386.

execution times. Now the Timing Tests simply leave the Clock Tick
Driver out of the Device Driver Table.

which does the following:
* some cleanups, fixes, addtions to the libbsp automake transition
patches
* The missing Automake transistion patches all libcpu/<cpu>/<variant>/*
previously not yet been converted to automake (libcpu/powerpc,
libcpu/hppa1.1, libcpu/mips64orion, libcpu/sparc)
=> With this patch, libcpu/*/* is under full automake control.
NOTES:
* This patch is tested by building for random set of bsps affected by
this patch, but not tested for all BSPs.
* The parts of this patch related to libcpu/powerpc fix many small bugs
inside of those Makefiles.
* Have a look into libcpu/powerpc/mpc6xx/, which is in rather bad shape,
IMO. Obviously most subdirectories seem to be build but are not included
into libcpu.a by wrapup/Makefile. Addtionally, no actual BSP uses this
cpu-variant subdirectory. Furthermore libcpu/powerpc/mpc6xx has a
different directory layout than all other powerpc/<variant>/
directories.
Joel's note: I agree but the issue is that there is a conflict between
including timer or clock in libcpu/XXX/wrapup/Makefile.* and letting
a BSP specifically decide to pick it up. There is no clear solution
to this at the moment.

In another attempt to get C++ exceptions working on the gen68360 target
I tried building for the m68k-elf target. All the tools built and
installed properly as did all of RTEMS. No applications would run,
though -- not even hello.exe!
It turns out the problem was in the linker script. The alignment was in
the wrong place.
Here's a patch. Exceptions still don't work, but at least I can get
some things working with the ELF format now.

which fixes a couple of bugs in RTEMS's old style Makefile.ins, which
apparently were introduced by moving the start directories and not
having adapted the Makefile.ins.

I got tired of having strange clock rates (e.g. #define
CONFIGURE_MICROSECONDS_PER_TICK 52489) and drifting times-of-day with
the gen68360 BSP so I changed the way the programmable-interval clock
interrupt works. The new version will have some jitter in the intervals
between individual calls to the rtems_clock_tick routine, but the
long-term average will match the CONFIGURE_MICROSECONDS_PER_TICK

Renamed file shmsupp/intr.c in some BSPs to shmsupp/cause_intr.c to
avoid conflict with rtems/src/intr.c (Classic API Interrupt Manager).

which (among other things) converted the mptests to automake.
SUB_DIRS was used instead of SUBDIRS in some Makefile.ins
(apparently a leftover from moving the start* directories)
Addtional major bugs:
* psxtests/include was empty (incomplete psxtests changes).
* bogus handling of *.scn in itrontests (screens/sptests vs.
screens/itrontests installation dirs)
In addition I have added a few more changes (I couldn't resist)
* automake support for itrontests
* OPERATION_COUNT support in tmitrontests/
* automake support for tmitrontests
* automake suppport for mptests
* Some (minor) corrections to several configure.in/Makefile.ams
=> c/src/tests/ is completly under automake control, now.
=> we could start to sort out the structural issues with c/src/tests
(tests/support, stubdr, tools, get "make dist" working)

small fixes for Makefile.ins/configure.ins below c/src/lib."

.. a major configuration cleanup
... major enhancement of automake support.
... and it contains a *major* breakthough:
Automake support for libchip and libmisc *LEAF* directories.
To implement this I have used several nasty tricks
* The basical trick is to wrap an old Makefile.in's contents into a
Makefile.am and still continue to use (i.e include) the old
*.cfg files.
* Replaced each INSTALL_IF_CHANGE and INSTALL_VARIANT with make
dependencies
* Add a gnu-make ifdef AUTOMAKE to main.cfg to avoid conflicts between
automake and RTEMS make rules
* Replaced each install:: and preinstall:: rule with make dependencies
* Replaced SUB_DIRS with SUBDIRS in all Makefile.ins (Automake
convention)
* Removed each manually added autoconf substitution which automake
performs automatically.
This is not yet full automake support, because using the temporary
installation directory, preinstallation in general and building variants
are in contradiction to automake's basic working principles ...
... the new Makefile.ams work still somewhat clumsy
... nevertheless they work (quite well).
WARNING:
At first glance this patch is small, but
* it affects the whole configuration system.
* it opens the road to introducing automake to all Makefile.ins
currently not being under automake control.
JOEL> Does this remove or add any files?
Both, all Makefile.ins below libchip and libmisc get replaced with
Makefile.ams.
