* Patch from Eric Norum <eric@cls.usask.ca> to add "attaching" argumentJoel Sherrill2000-08-022-3/+11
| | | | to driver attach routine.
* Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill2000-06-121-0/+3
| | | | | | | | | | | | | | | <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
* Merged from 4.5.0-beta3aJoel Sherrill2000-06-1218-110/+181

* Patch rtems-rc-4.5.0-13-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>.Joel Sherrill2000-04-139-0/+29
| | | | adds .cvsignore.
* Patch from Eric Norum <eric@cls.usask.ca> based on working withJoel Sherrill2000-02-113-1/+45
| | | | | | | | | | | | | | | | | | | | 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.
* Patches rtems-rc-20000204-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2000-02-082-5/+11
| | | | | | | | | | | | | | | | | 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)
* Patch from Eric Norum <eric@cls.usask.ca> to remove race conditionsJoel Sherrill2000-02-081-3/+9
| | | | when setting up receive buffer descriptors and when unmasking interrupts.
* Patches rtems-rc-20000118-7.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2000-02-031-2/+0
| | | | | | | | | | | | | | | | | 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.
* Patches rtems-rc-20000118-5.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2000-02-011-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | 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). To apply: patch -p1 <rtems-rc-20000118-5.diff cvs rm -f ./c/src/lib/libbsp/Makefile.in cvs rm -f ./c/src/lib/libbsp/shmdr/Makefile.in cvs rm -f ./c/src/lib/libcpu/Makefile.in cvs add ./c/src/lib/libbsp/Makefile.am cvs add ./c/src/lib/libbsp/shmdr/Makefile.am cvs add ./c/src/lib/libcpu/Makefile.am ./bootstrap

* Patches rtems-rc-20000118-3.diff and rtems-rc-20000118-4.diff fromJoel Sherrill2000-01-3116-521/+278
| | | | | | | | | | 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
* Patch from Eric Norum <eric@cls.usask.ca>:Joel Sherrill2000-01-211-28/+16
| | | | | | | | 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.
* Updated files missed in earlier batch from Eric Norum.Joel Sherrill2000-01-132-26/+18

* All m68k BSPs now build with new ELF style linkcmds.Joel Sherrill2000-01-132-8/+8
|
* New patch from Eric Norum plus some minor mods by Joel.Joel Sherrill2000-01-138-361/+310
|
* Made _clear_end a "PROVIDE."Joel Sherrill2000-01-131-1/+1
|
* Eric Norum <eric@cls.usask.ca> submitted linker script and bsp_specsJoel Sherrill2000-01-122-37/+68
| | | | | | | | 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.
* Patch rtems-rc-20000104-16.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2000-01-124-71/+99
| | | | that converts the libbsp/i386 subdirectory to full automake.
* Removed old hack of using Configuration Table entry ticks_per_timesliceJoel Sherrill2000-01-111-41/+37
| | | | | | | being set to 0 to indicate that there should be no Clock Tick. This was used by the Timing Tests to avoid clock tick overhead perturbing execution times. Now the Timing Tests simply leave the Clock Tick Driver out of the Device Driver Table.
* Fixed unterminated comment spotted by eagle eye Ralf CorsepiusJoel Sherrill2000-01-101-0/+1

* Patch rtems-rc-20000104-10.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2000-01-1011-55/+74
| | | | | | | | | | | | | | | | | that converts the m68k directory to automake. NOTE: This one is fully tested by building *all* bsps with ../../rtems-rc-20000104/configure \ --target=m68k-rtems \ --prefix=/tmp/rtems \ --enable-cxx \ --disable-posix \ --enable-rdbg \ --disable-networking \ --enable-maintainer-mode \ --enable-multiprocessing \ --disable-tests make
* patch from Eric Norum <eric@cls.usask.ca> as follows:Joel Sherrill2000-01-051-0/+124
| | | | | | | | | | | At the request of kjoutwater@west.raytheon.com I'm submitting the following patch. c/src/lib/libbsp/m68k/gen68360/console/console.c Allow console baud rate to be set by debugger/downloader. c/src/lib/libbsp/m68k/gen68360/startup/init68360.c Add support for generic 68360 with static RAM.

* Patch from Eric Norum <eric@cls.usask.ca>:Joel Sherrill2000-01-033-1/+5
| | | | | | | | | | | | | 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.
* Updated times.Joel Sherrill2000-01-032-150/+150

* Patch rtems-rc-19991203-10.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-12-211-1/+1
| | | | | | | | | | 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. To apply: patch -p1 < rtems-rc-19991203-10.diff
* Patch from Eric Norum <eric@cls.usask.ca> to change to gen68360 clock handling.Joel Sherrill1999-12-131-30/+56
| | | | | | | | | 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
* Patch rtems-rc-19991123-rc-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-11-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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)

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-07-2610-10/+10
| | | | | | | | | | | | | | | | | | | | | A bug in acpolish made it into rtems-rc-19990709-0.diff, which unfortunately affects all Makefile.ins: * The maintainer mode conditional was erroniously applied to the dependencies of "Makefile". In case you already checked in rtems-rc-19990709-0.diff to CVS you have to check in all Makefile.ins again after applying the patch below :). Please apply the patch below as follows: patch -p1 < rtems-rc-19990709-1.diff tools/update/rtems-polish.sh -ac Note: There is no need to rerun your tests if you have used --enable-maintainer-mode to configure RTEMS, because this patch converts all Makefile.ins to the same settings as used for --enable-maintainer-mode.
* This is part of a major patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-07-2610-199/+214

Finally, here they are: the "big-patch" patches - merged into one big patch (~1.5MB). Sorry for the delay, but testing took much more time than I had expected - esp. reworking the acpolish script triggered many more tiny issues than I had expected (cf. below). At least, now you've got something to spend your weekend with :-. WARNINGS: * I've gone a little (??) further than I had announced before. * Several directories have been moved. * Several files have been added and removed * I have tested it with many BSPs/CPUs and a variety of permutiations of configuration flags, but not with all. * Most parts of the patch are automatically generated, however there are many tiny manual modifications. APPLYING THE PATCH: ./autogen -c mkdir tools mv c/src/exec/score/tools tools/cpu mv c/build-tools tools/build mv c/update-tools tools/update patch -p1 -E < rtems-rc-19990709-0.diff ./autogen If the patch doesn't apply to rtems-cvs, I would suggest that you should try to apply it brute-force and then to run tools/update/rtems-polish.sh -ac -am afterwards. A recursive diff between rtems-19990709 + patch and rtems-cvs + patch then should report only a few dozen significant changes to configuration files which need to be merged manually (IIRC, I did not change any source files). *** Attention: There are files to be removed, moved, copied and added in/to CVS! NEWS/CHANGES: 1. Configuration takes place in 3 stages: 1. per host (toplevel configure script), 2. per target (c/configure), 3. per bsp c/src/configure automatically triggered from ./configure and c/Makefile.am. 2. Building of subdirectory c/ takes place in c/$(target_alias) for cross-targets in c/ for native targets 3. Building of subdirectory c/src takes place in c/${target_alias}/<bsp> for cross-targets, c/<bsp> for native targets 4. c/build-tools moved to tools/build 5. c/src/exec/score/cpu/tools moved to tools/cpu (=cpu-tools split out) 6. c/update-tools moved to tools/update 7. New subdirectory c/src/make, handles files from make/ on a per BSP basis 8. Maintainer mode support: Ie. if configuring with --enable-maintainer-mode disabled (the default), then tracking of many dependencies will be disabled in Makefiles. Esp. many dependencies for auto* generated files will be switched off in Makefiles. Ie. if not using "--enable-maintainer-mode" many auto* generated files will not be updated automatically, i.e. normal users should not be required to have auto* tools anymore (untested). 9. Independent configuration scripts for / (toplevel), tools/build, tools/cpu, tools/update, c/, c/src/, c/src/exec, c/src/lib, c/src/tests, c/src/make 10. Automake support for all directories above and besides c/src 11. "preinstall" now is implemented as depth-first recursive make target 12. host compiled tools (exception bsp-tools) are accessed in location in the build tree instead of inside the build-tree when building RTEMS. 13. RTEMS_ROOT and PROJECT_ROOT now point to directories inside the build-tree - many tiny changes as consequence from this. 14. --with-cross-host support removed (offically announced obsolete by cygnus) 15. Changing the order of building libraries below c/src/lib/ 16. Former toplevel configure script broken into aclocal/*.m4 macros 17. Newlib now detected by configure macros, RTEMS_HAS_NEWLIB removed from *cfg. 18. sptables.h now generated by autoconf 19. Rules for "mkinstalldirs temporary installation tree" moved from c/Makefile to subdirectories. 20. Cpu-tools do not get installed. 21. FIX: Use ACLOCAL_AMFLAGS instead of ACLOCAL = -I ... in Makefile.ams which are in directories with own configure scripts. 22. Hardcoding BSP names into libbsp/.../tools to avoid RTEMS_BSP get overridden from the environment. 22. FIX: Handling of MP_PIECES in various Makefiles 23. FIX: Removing "::" rules from some Makefile.ins 24. FIX: File permission chaos: (-m 444 and -m 555 vs. -m 644 and -m 755) - Now all include files use -m 644. 25. Removed many gnumake-conditionals in Makefile.ins - Partially replaced with automake-conditional, partially replaced with conditionalized Makefile variables (... _yes_V) 26. Massively reworked acpolish: acpolish now parses Makefile.ins and interprets parts of the Makefile.ins. 27. FIX: Some $(wildcard $(srcdir)/*.h) macros removed / replaced with explicit lists of files in Makefile.ins. 28. FIX: Replacing MKLIB with RANLIB in Makefile.ins 29. HACK: Add preinstallation for pc386 specific $(PROJECT_RELEASE)/BootImgs directory ... many more details, I can't recall KNOWN BUGS: 1. make [debug|profile]_install do not do what they are promissing. "make [debug|profile] install" does what "make [debug|profile]_install" has been doing. Proposal: remove [debug|profile]_install 2. Dependencies between temporary installation tree and source tree are not yet handled correctly. 3. Dependencies between temporary installation tree and source tree are handled ineffencently (Using INSTALL_CHANGE instead of make dependencies) 4. RTEMS_ROOT, PROJECT_ROOT, top_builddir, RTEMS_TOPdir now are redundant. 5. The new configure scripts still are in their infancy. They contain redundant checks and might still contain bugs, too. 6. RTEMS autoconf Makefile.ins use a mixture of configuration information gathered in c/$(target_alias)/<bsp>/make and of information collected from their configure scripts. 7. make dist is not fully functional 8. Subdirectory host-/build-/target- configure options (--target, --host, --build) do not conform to Cygnus/GNU conventions. 9. Some RTEMS autoconf Makefile.in's makefile targets are not supported in automake Makefile.ams/ins (e.g. get, clobber). 10. Some automake standard targets are not propagated from toplevel and c/Makefile.am to autoconf subdirectories (eg. make dist). 11. rpcgen generated files are not part of the source-tree (Automake conventions favor supplying generated files inside the source-tree, however there is no support for rpcgen generated files in automake, cf. yacc/lex support in automake). 12. RTEMS_HAS_RDBG handling is flaky. make/*.cfg use RTEMS_HAS_RDBG per CPU, while librdb's sources can only be built per BSP. Raises the more general question whether librdbg located correctly in the source-tree. 13. All make/*cfg files are configured per cpu, currently there is no location to store per-bsp configuration information --> bsp.cfg, per aconfig.h? 14. "make install" without having run "make all" beforehand does not work. 15. handling of --enable-multiprocessing seems to be broken in make/custom/* 16. Makefile.ins still exploit many gmake features. 17. File permisson chaos on libraries (no explict -m for libraries/rels/etc). 18. mcp750 Makefiles are broken (Note: I *do* mean buggy - I am not talking about "not-conforming to conventions", here :-). 19. Dependencies between configure scripts are not handled, eg. aborting "make RTEMS_BSP=<bsp>" can leave the build-tree in an unusable state. 20. "make clean" does not delete <build-tree>/<bsp>. This is intentional for now, because rerunning "make" after "make clean" requires an explicit "make preinstall" afterwards now. This should be done automatically, but doesn't work in this case for now. To work around this problem <build-tree>/<bsp> is kept during "make clean" for now (HACK). TODO: 1. split out host-compiled bsp-tools 2. Use Cygnus/GNU standards for cross-compiling target-subdir (CC=CC_FOR_TARGET .. configure --host=${target_alias} --build=`config.guess'}), to be added to toplevel configure script after splitting out bsp-tools. 3. Exploit per cpu support directory (c/src/<cpu>)- Splitting out per-cpu libraries - Are there any? 4. Further automake support 5. Converting subdirectories into standalone / self-contained subdirectories (Esp. moving their headers to the same common root as their sources, eg. mv lib/include/rtems++ lib/librtems++/include/rtems++) - This is the main obstacle which prevents moving further towards automake. 6. Propagating values from *.cfg into Makefiles instead of propagating them at make time via Makefile-fragments (i.e. try to avoid using *.cfg). 7. Testing on cygwin host (I *do* expect cygwin specific problems). 8. The ARCH in o-$(ARCH)-$(VARIANT) build-subdirectories is not needed anymore. GENERAL ISSUES: 1. Temporary installation tree -- Ian and I seem to disagree basically. Though I think that I understand his argumentation, I do not share it. IMO, his way of using the buildtree is mis-using the build-tree, relying on an inofficial feature of RTEMS's current implementation, which doesn't even work correctly in the current build-tree, though it attempts hard to do so. From my very POV, it unnecessarily complicates the structures of the source- and build-trees. It is not supported by automake (No automatic generation for the necessary rules) and complicates the transition to automake significantly (Generating the rules with an enhanced version of acpolish could be possible). As Ian correctly pointed out, here a management decision is needed - though I don't see the need to draw this decision in short terms. 2. preinstallation generally is a sure means to spoil the structure of the source tree, IMHO (No ranting intended, I am completly serious about this one). eg. through tree dependencies. The worst problem related to this I have found in the meantime is bsp_specs. bsp_specs is part of libbsp, ie. there is *no* way to build *any* part of the source tree *without* having a BSP *preinstalled*. Note: This issue is related to issue 1., but is not identical - The difference is the change of the order make rules have to be triggered. While preinstallation triggers rules spread all over the source tree before a "make all" can be run, a temporary installation tree could also be installed by post "make all" hooks (all-local:, to be run after make all in a directory is completed) if the directories' dependencies would be a tree, 3. Stuctural dependencies between subdirectories. 4. Depth of the source tree (Prevents multilibbing and introduces many unnecessary configure scripts). 5. per cpu vs. per bsp configuration (There are no real per-cpu parts yets :-). 6. automake does not support $makefiles in AC_OUTPUT. Unlike before, we now should try to avoid RTEMS_CHECK_MAKEFILE and to hard-code as much paths to Makefiles as possible. 7. General redesign of the source tree 8. Main installation point - Changing it to ${prefix}/${target_alias}. ? Besides item 8. (which is a must, IMHO), as far as I see most of them can not be solved soon and will remain issues in the mid- to long-term :-. REMARKS: * You (as the maintainer) should always use --enable-maintainer-mode when building RTEMS to ensure that maintainer mode generated files (esp. those in c/src/make) will be updated when make/* files have changed. * Use @RTEMS_BSP@ in Makefile.ins and Makefile.ams below c/src/, $(RTEMS_BSP) or ${RTEMS_BSP} will be overridden from environment variables when using make RTEMS_BSP="....". * c/src/make is a temporary cludge until configuration issues are solved. At the moment it is configured per bsp, but contains per-target/cpu info only. Its main purpose now is to circumvent modifying make/*.cfg files, because I consider make/* to be frozen for backward compatibilty. * This patch should only affect configuration files. At least I do not remember having touched any source files. * To build the bare bsp you now need to mention it in --enable-rtemsbsp. Example: building gensh1 and sh1/bare simultaneously: ../rtems-rc-19990709-1/configure --target=sh-rtems \ --enable-rtemsbsp="bare gensh1" \ --prefix=/tmp/rtems \ --enable-bare-cpu-cflags='-DMHZ=20 -m1 -DCPU_CONSOLE_DEVNAME=\"/dev/null\"' \ --enable-bare-cpu-model=sh7032 \ --enable-maintainer-mode \ --enable-cxx make make install * The next steps in development would be to split out bsp-tools and then to change to Cygnus/GNU canonicalization conventions for building the c/ subdirectory afterwards (i.e. many standard AC_*.m4 macros could be used instead of customized versions) FINAL REMARK: The issues mentioned in the lists above sound much worser than the situation actually is. Most of them are not specific to this patch, but are also valid for the snapshot. I just wrote down what I came across when working on the patch over the last few weeks. I wouldn't be too surprised if you don't like the patch at the current point in development. I am willing to discuss details and problems, I also have no problem if you would post-pone applying this patch to times after 4.1, but rejecting it as a whole for all times would be a false management decision, IMHO. Therefore I would suggest that you, if your time constaints allow it, should at least play a little while with this patch to understand what is going on and before drawing a decision on how to handle this proposal. I know this patch is neither perfect nor complete, but I consider it to be a major breakthrough. Don't be anxious because of the size of the patch, the core of the patch is rather small, the size is mainly the side effect of some systematic cleanups inside the Makefiles (result of acpolish). Feel free to ask if you encounter problems, if you don't understand something or if you meet bugs - I am far from being perfect and am prepared to answer them.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> that splitsJoel Sherrill1999-07-021-1/+1
| | | | | | boot_card() and main() into separate files to ease configuration of other packages. This was a big step in the way to build TCL, ncurses, and zlib for RTEMS.
* Added dummy gnatinstallhandler code for all BSPs. This lets Ada programsJoel Sherrill1999-06-241-1/+1

* Switched from picking up the .rel for each subdirectory in theJoel Sherrill1999-05-271-1/+1

* After discussion with Eric Norum <eric@skatter.usask.ca>,Joel Sherrill1999-04-191-2/+1

| | | | | | | | | | | | | | 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
* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> to preinstallJoel Sherrill1999-04-061-2/+0

| | | | | | | I'd like to make the following change which adds the m360 structure information to the debugging symbols in the final executable. This makes it much easier to use the debugger to look at the elements of the m360 structure.
