* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-04-194-4/+4
| | | | | | | | | | | | | | 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
* Towards automake XI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-194-12/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-02-181-6/+1
| | | | | | | | | | | | | This patch removes generation of targopts.h from leaf.cfg and generates it in location at score/include/rtems/score instead. To achieve this: * all rules in other Makefile.ins which have accessed targopts.h have been removed. * c/Makefile.in has been modified to generate the directories before doing anything else. I.e. to ensure the directories exist before any preinstall rule fires (This part is a bit kludgy, but it seems to work. Please check if the interaction with libhwapi still works).
* Patch from Jiri Gaisler <jgais@ce.chalmers.se>:Joel Sherrill1999-01-192-2/+4
| | | | | | | | getting the spurious trap handling to work required a couple more fixes - I have attached a patch against rtems-4.0.0 with the necessary changes. I also added functionality so that the address of the trapped instruction is reported and in case of a data access error, the data address is also reported.

DEBUG_puts() seems to be the only user of ERC32_Restore_interrupt() anyway ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | external interrupt priorities were not being honored. Here is some of his original report: using rtems/erc32, I have a problem with interrupt priority when interrupts occure simultaneously. Erc32 has an interrupt force register where interrupts can be generated. If more than one interrupt is generated, the interrupt handlers are scheduled in the wrong order, i.e. with the lowest priority first. I have attched a program that generates three interrupts, 0x11, 0x12 and 0x13. Interrupt 0x13 should be handled first, but is actually handled last. Below is the output from sis: sis> go resuming at 0x02000000 RAM size: 4096 K, ROM size: 2048 K Watchdog disabled Waitstates = RAM read: 0, RAM write: 0, ROM read: 0, ROM write: 0 Power-down mode enabled infinite UART baudrate External interrupt received with vector 0x11 External interrupt received with vector 0x12 External interrupt received with vector 0x13 I have verified that sis generates the interrupts in the correct order, i.e. 0x13 first, then 0x12 and then 0x11. So the problem seems to be in the rtems interrupt handler. Do you use the PIL field in the %psr register to mask lower priority interrupts or are all external interrupts considered to have the same priority ..? Here is a description of the fix: it turned out that lower priority interrupts were not at all masked off during interrupt handling. I made the following fix to cpu_asm.s: ... fix is in the code ... There might be a simpler way of doing this, but this works...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working with different shells and relative/absolute paths. What I did is relatively simple in principle: Instead of setting RTEMS_ROOT in configure.in and then let configure substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile set RTEMS_ROOT from each Makefile's @top_srcdir@ value. The difference is subtile, but with enormous side effects: - If RTEMS_ROOT is set in configure, then the same single value will be propagated to all Makefiles. This breaks using relative paths, as the relative path to the root of the source tree is used inside of all subdirectory Makefiles. - Now each Makefile.in sets RTEMS_ROOT = @top_srcdir@. top_srcdir is computed individually by configure for each single Makefile.in, hereby receiving the correct value, no matter if relative or absolute paths are used. To get this working, I needed to remove setting RTEMS_ROOT from target.cfg.in, because this overrides the value of RTEMS_ROOT from each individual Makefile. Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all "include $(RTEMS_CUSTOM)" directives with"include $(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this, but I think, to have one variable less is clearer and easier to understand than having several variables refering to the next one. I enclose a small patch to this mail, which - fixes the config.h problem (to finally clearify misunderstands) - removes assignment/subsitution of RTEMS_ROOT from configure.in - contains a workaround for the application Makefile's RTEMS_ROOT problem (reported by Eric) - removes some unused lines from the toplevel Makefile.in - removes assignment of RTEMS_ROOT from make/target.cfg.in

It is turned on is the bsp enables it and it is not explicitly disabled via the configure option --disable-tcpip. As many warnings as possible were removed locally after the code was merged. Only the gen68360 and mvme136 bsps were compiled this way. The ka9q port and network driver were submitted by Eric Norum (eric@skatter.USask.Ca). The network demo programs are not included in the tree at this point.

* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-011-0/+74
| | | | | | | | | | | | | | | | | | | | GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots. These will be resolved.
