* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-04-199-9/+9
| | | | | | | | | | | | | | 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 Sherrill1999-03-199-30/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Towards automake X patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-191-0/+5
| | | | | | | | | | | | | | | | | | | This one once again changes the scheme to preinstall bsp_specs. It moves generating PROJECT_ROOT/lib/bsp_specs to libbsp/<cpu>/<bsp>/wrapup/Makefile.in. I.e. it decentralizes generation of bsp_specs to a bsp-dependent directory, because preinstalling bsp_specs in a centralized Makefile like it has been done until now does not harmonize well with spliting the toplevel configure script in cpu and bsp-dependent configure scripts and automake. First apply the patch (rtems-rc-19990318-0.diff) below, then run the reorg-bsp_specs.sh script. IMO, this one is comparatively harmless and eases automake support significantly.

* Updated Ethernet driver from Erik Ivanenko <erik.ivanenko@utoronto.ca>.Joel Sherrill1999-03-011-66/+112
| | | | | | | | | | | | | | | | | | | | | | | | | Comments follow: Please find attached, the updated network driver. I have verified that it is working as expected, by timestamping the error messages generated from the ISR. If you've taken a look inside, the network driver has a reset thread in addition to the RX and TX threads. It is possible to avoid the additional reset thread by allowing the TX driver to time out and then checking status bits set by the ISR. However, this approach demands that a transmission is necessary for the NIC to be reset. Due to Eric V's ISR handling, I suppose that the reset routine could be called from the "ISR" itself, due to the 8259 interrupt mode, and that the interrupt is acknowledged prior to running the "ISR". (Providing that no NIC interrupts are generated during reset -- I worry about re-entrancy. ) This would be a minor improvement, but you know, I don't want to make this driver my lifes work. ---------------------------------------------------------------------- ----------------------------------------------------------------------

| | | | | | | | | | | Comments follow: Here is the contents of the network directory of the i386ex BSP. The reset function has been recently added, and tested through a command line interface. A reset event to the reset thread to reset the NIC. This is done when the ISR detects that the NIC is in an invalid state. It has not been tested "in real life" since the board has not seen an invalid state since the reset function was implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | moves pieces of the pc386 bsp up to a shared level for all i386 BSPs and modifies the i386ex BSP to use those shared pieces. Serial remote debugging is included for both targets. Erik's notes: There are several workarounds in it: 1) #define NEXT_GAS is hardcoded in pc386/start/start.s 2) #define NEXT_GAS is hardcoded in i386ex/start/start.s 3) #define NEW_GAS is hardcoded in pc386/start16.s 4) #undef __assert and redeclare _assert hardcoded in console.c for both pc386 and i386ex due to my egcs1.1b ~ newlib problem. Should have modified t-rtems.cfg ( no time ) I've tested pc386 with both video and serial consoles and GDB remote. All work fine, except that GDB acts weird. ( re: other posting) I hope this will work for you. It took quite some time to locate the autoconf error. The remainder was just grunt work. Unfortunately, I think I've unwound the removal of the IBMPCInitVideo stuff. Sorry. I REALLY can't spend more time... I've been at this conversion to 4.0 locally and updating the release since Sept. 8th, and have yet to compile my network driver.... This is as much as I can do right now. I look forward to the next patch to really test i368ex. I did make sure that the sample tests worked for pc386.

| | | | | | | | | | | | | | | | Please find attached a start.s that includes a cli prior to the hlt instruction. This ensures that external interrupts cannot restart the system after returning to the startup code. ( According to the hlt docs, they will! ) Also find a new timer.c. ( I forgot to update the countdowm value in the timer when I changed the PSCLK frequency in start.s) . This improves timer accuracy. The raw_idt_notify messages are no longer infinite, I tested sp11 and sp05, both which were bad, and I have seen the message print once in one test. I think it's ok if it prints out once. In fact, I don't think you can effectively stop it!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Please find attached the two files that have been changed relative to 980921 . The changes here are in the handling of the counter-timer used as the basis for the rtems executive clock. For the most part, these are housekeeping changes. The PSCLK frequency change in start.s... was a part of several bug-fixes. The fix improves executive clock and timer accuracy. changes : start.s -- All timers are disabled by the initialization routine -- PSCLK ( used by clock and timers ) frequency changed to 1MHz The clock_initialize routine now assumes that the PSCLK frequency is exactly 1 MHz. ckinit.c Clock_isr -- removed division by 1000. Now use 'static' variable -- clock_intial_isr_value -- to reset Clock_isrs variable. clock_initialize -- moved counter timer initialization here. Values used to configure the timer are totally dependent on BSP_configuration.microseconds_per_tick ( and the PSCLK assumption). Initializes clock_initial_isr_value used by th Clock_isr to reset Clock_isrs. clock_on -- no longer configures the timer, just enables it. Since altering the number of sections in the BSP, I decided to give it a good "once over" . The clock handling is now cleaner.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Moved -qnolinkcmds option so arguments passed on the command line areJoel Sherrill1997-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | interpreted at the right point per Eric Norum's discovery: The problem with the my previous `fix' for adding linker commands was with the ordering of the options to the linker. For example, to make a larger heap size, the application Makefile would CFLAGS_LD = -Wl,--defsym -Wl,HeapSize=0x40000 The command passed to the linker would be : m68k-rtems-ld .... -T xxx/linkcmds .... --defsym HeapSize=0x40000 ..... This doesn't work because the script in linkcmds inserts a default value for HeapSize if HeapSize is not defined by the time the linker looks at the linkcmds script. The solution seems to be to move the -T linkcmds%s in the bsp_specs file out of the link specfication and into the lib specification -- a little unorthodox, perhaps, but it seems to work!
