| | | | | | | | | | <valette@crf.canon.fr> to add a port of the GoAhead web server (httpd) to the RTEMS build tree. They have successfully used this BSP on i386/pc386 and PowerPC/mcp750. Mark and Joel spoke with Nick Berliner <nickb@goahead.com> on 26 Oct 1999 about this port and got verbal approval to include it in RTEMS distributions.
* Patch from Eric Norum <eric@cls.usask.ca> to address the following problemJoel Sherrill1999-10-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | report from Philip A. Prindeville <philipp@zembu.com>: I was working on a device driver for a certain ethernet chipset that occassionally wraps in its buffer, and causes a resulting mbuf chain with only a few dozen bytes in the first mbuf of the chain. I wouldn't have thought this would be a problem, until I ran some stress tests that flooded the ethernet receiver with packets and started to get panics here: 250 251 if (m->m_pkthdr.len < sizeof(struct ip)) 252 goto tooshort; 253 254 #ifdef DIAGNOSTIC 255 if (m->m_len < sizeof(struct ip)) 256 panic("ipintr mbuf too short"); 257 #endif 258 259 if (m->m_len < sizeof (struct ip) && 260 (m = m_pullup(m, sizeof (struct ip))) == 0) { 261 ipstat.ips_toosmall++; 262 return; 263 } 264 ip = mtod(m, struct ip *); and the panic was at line 256. But if I #undef'd DIAGNOSTICS, then the m_pullup() at line 260 does the right thing and the packet ends up being processed just fine. So I started wondering, (a) why was the test checking for something that apparently wasn't a fatal condition but rather one that is subsequently recovered from a couple of lines later and (b) why panic as a diagnostic "aid" from a recoverable condition rather than just (say) log a message to the console? All of this seems overly severe for no reason that is readily apparent to me.

* Modified to avoid conflicts on definitions of malloc. newlib 1.8.2Joel Sherrill1999-10-063-3/+3
| | | | | | | | now prototypes the malloc family in stdlib.h. This causes conflicts with the way the network stack overrides the definitions of malloc. As best I (being Joel) can tell, commenting stdlib.h out keeps the files compiling and referencing the desired malloc/free but results in more warnings.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-10-041-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch below actuallly consists of two patches: 1) moving librpc to c/src/librpc similar to what has been done to librtems++ 2) reworked configure scripts, many safety and dependency checks added to aclocal/*.m4 macros + configuration fixes. To apply: mkdir c/src/librpc mkdir c/src/librpc/src cp c/src/lib/librpc/*.c c/src/librpc/src cp c/src/lib/librpc/Makefile.in c/src/librpc/src mkdir c/src/librpc/include mkdir c/src/librpc/include/rpc cp c/src/lib/include/rpc/* c/src/librpc/include/rpc patch -p1 < ../rtems-rc-19990820-7.diff rm -rf c/src/lib/librpc rm -rf c/src/lib/include/rpc ./autogen The additional checks in aclocal/*m4 macros add rather restrictive, sometimes unnecessarily restrictive constraints on the sequence of how macros can be used in a configure.in script. Adding them has let my problems with some more complicated configuration options vanish. Apparently some macros had not been in the required order . ---- Now I still get some linking errors for some cpus and bsps, esp when linking cdtest, but also at other locations: e.g. this happens for mips64orion/p4600: # make[5]: Entering directory `/lfs/poseidon/users/rtems/src/multi/build/mips64orion-rtems/c/p4600/tests/samples/hello' /opt/rtems/bin/mips64orion-rtems-gcc --pipe -B../../../../../../p4600/lib/ -specs bsp_specs -qrtems -DP4000 -DCPU_R4000 -DP3_DIAG -D_R4000 -D__mips=3 -mcpu=4600 -G0 -I../../../../../../p4600/lib/include/networking -g -Wall -ansi -fasm -O4 -fomit-frame-pointer -o o-p4600/hello.exe o-p4600/init.o ../../../../../../p4600/lib/no-dpmem.rel ../../../../../../p4600/lib/no-event.rel ../../../../../../p4600/lib/no-msg.rel ../../../../../../p4600/lib/no-mp.rel ../../../../../../p4600/lib/no-part.rel ../../../../../../p4600/lib/no-signal.rel ../../../../../../p4600/lib/no-timer.rel ../../../../../../p4600/lib/no-rtmon.rel /opt/rtems/mips64orion-rtems/lib/libc.a(dtoa.o): In function `_dtoa_r': /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol collect2: ld returned 1 exit status # mips64orion-rtems-gcc -v Reading specs from /opt/rtems/lib/gcc-lib/mips64orion-rtems/2.95.1/specs gcc version 2.95.1 19990816 (release) # mips64orion-rtems-ld -v GNU ld version 2.9.5 (with BFD 2.9.5)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main topic is replacing the hard-coded values for HAS_MP and HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks (This is the patch I had mentioned before earlier this week). CHANGES * HAS_MP removed from custom/*.cfg, replaced with configuration time autoconf check * HAS_RDBG removed from custom/*.cfg, replaced with configuration-time autoconf check * NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp values (i.e. HAS_MP, HAS_RDBG), gets installed as $(prefix)/<bsp>/make/bsp.cfg * NEW: default.cfg includes bsp.cfg - this change is backward compatible. * IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory Makefile.ins * HACK: a bug in acpolish mis-handles addtions to makefile variables which are enclosed in gmake conditionals: c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in * Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of unneeded subdirectories in various configure.in files. * Several minor changes in Makefile.ins and configure.ins, wrt. to the order of including *.cfg and defining Makefile variables APPLYING THE PATCH: patch -p1 < rtems-rc-19990709-4.diff ./autogen

| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to move RTEMS more to automake/autoconf and GNU compliance. 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 Eric Norum <eric@cls.usask.ca>:Joel Sherrill1999-07-121-20/+15
| | | | | | | | | | | | | | I get the following warning when compiling the latest snapshot. I had a quick look at the source -- it certainly looks to me like this is a real bug. ../../../../src/rtems-19990709/c/src/lib/libc/mount.c:97: warning: `options' might be used uninitialized in this function Also, I changed the TFTP test program and TFTP driver to reflect the changes in the way paths are passed to the TFTP driver. The TFTP driver now needs a proper `dotted-decimal' hostname as the second component of the path name.

* Patch from Ian Lance Taylor <ian@airs.com>:Joel Sherrill1999-06-114-2/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The select function is not particularly efficient when dealing with a large number of sockets. The application has to build a big set of bits and pass it in. RTEMS has to look through all those bits and see what is ready. Then the application has to look through all the bits again. On the other hand, when using RTEMS, the select function is needed exactly when you have a large number of sockets, because that is when it becomes prohibitive to use a separate thread for each socket. I think it would make more sense for RTEMS to support callback functions which could be invoked when there is data available to read from a socket, or when there is space available to write to a socket. Accordingly, I implemented them. This patch adds two new SOL_SOCKET options to setsockopt and getsockopt: SO_SNDWAKEUP and SO_RCVWAKEUP. They take arguments of type struct sockwakeup: struct sockwakeup { void (*sw_pfn) __P((struct socket *, caddr_t)); caddr_t sw_arg; }; They are used to add or remove a function which will be called when something happens for the socket. Getting a callback doesn't imply that a read or write will succeed, but it does imply that it is worth trying. This adds functionality to RTEMS which is somewhat like interrupt driven socket I/O on Unix. After the patch to RTEMS, I have appended a patch to netdemos-19990407/select/test.c to test the new functionality and demonstrate one way it might be used. To run the new test instead of the select test, change doSocket to call echoServer2 instead of echoServer.

It was introduced when I did some cleanup on the sleep/wakeup handling in rtems_glue.c.

* Towards automake XI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-1911-33/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
