This one is an enhancement to acpolish.
It replaces some Makefile variables by others variable in Makefile.ins
(tries to use unique name for some variables). It therefore eases
parsing Makefile.ins for further automatic Makefile.in conversions in
future.
To apply:
cd <rtems-source-tree>
sh <path-to>/rtems-rc-19990407-8.sh
./autogen

This patch is the most scary of all proposals I've been mailing to you
this week until now.
It consists of 3 parts:
1. a patch
2. a perl script (acpolish)
3. a shell script wrapper to invoke the perl-script.
The perl-script reads in each Makefile.in and modifies them
("polishes/beautifies" them :-).
These modifications are not easy to describe:
Basically, it hard-codes some automake Makefile-variables and rules into
RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts
some settings/variables to configure scripts' requirements (Yes,
plural).
E.g. it adds the automake standard variables $top_builddir and $subdir,
adds dependency rules for automatic re-generation of Makefiles from
Makefile.in, adds support variables for relative paths to multiple
configure scripts etc.
The patch is a one-line patch to enable the support of the new features
added by acpolish.
The shell script is a wrapper which pokes around inside of the source
tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins.
acpolish is designed to be able to run several times on the same
Makefile.in and may once become a more general tool to convert RTEMS
Makefile.in to automake. Therefore, I'd like to keep it inside of source
tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it
doesn't make sense to export it outside of RTEMS.
To apply this:
cd <source-tree>
patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff
tar xzvf <path-to>/rtems-rc-polish.tar.gz
./rtems-polish.sh
./autogen
Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if
you decide to put it in an alternative place, please modify
rtems-polish.sh to reflect this change.
Later:
cvs rm make/rtems.cfg (It isn't used anymore)
cvs add contrib
cvs add contrib/acpolish
cvs commit
I've tested this intensively, but naturally I can't exclude bugs.
Ralf.
PS.: Most probably, this is the last "Towards automake" patch. The next
one probably will be a real automake patch.

Here are patches that bring 980911 back to what I think is a correct
version of raw IDT management as well as a correct initialisation
of video console and rtems managed interrupts.

Here is a brief description of the attached patch :
1) There was a bug in the code for the COM2 serial line driver. Aleksey
gave me a fix that fixes the driver code itself. I would like to thank
him again publicly,
2) I introduced constants in the serial driver code because I had a hard
time reading the meanning of hexadecimal values in the NS data book :)
3)You can now mix printk and printf on serial line (tested on COM2).
There is a #ifdef PRINTK_ON_SERIAL in console.c that enables to have
printk on console while printf on serial line,
4) Removed call to displayCpuInfo because anyway if was at the wrong
place for serial line console (too early). It can anyway be called at
application level,
5) The original printk was unable to display negative integer values
and was also recursive. It now works corectly,
All the modifications have been tested here on the COM2 port from
a PC running RTEMS to a PC running linux,
NB : there is still a bug on PC386 serial line : exit does not flush the
remaining output queue. As this is not a bug in the driver itself but
somewhere in PC386 initialization/termios relationship it will be part
of another patch.
NB2 : As Emmanuel excerced the exception hanlder code, while porting the
SMC driver to the new BSD stack, we found a bug in the exception
handler : it shall not delete the current thread in case we are running
at interrupt level. This will be part of another patch...

It fixes netboot build problem, KA9Q configuration
for pc386, some compiler wardning, it also removed some stuff
ifdef'ed with '#if 0'.

inline with the new IRQ structure.
