* Corrected and added sections to link cleanly under i386-rtemself.Joel Sherrill1998-05-041-35/+44
|
* Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1998-04-152-29/+0
| | | | | | | | | | | | code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
* Transitioned to shared bsp_libc_init() and cleaned up comments.Joel Sherrill1998-04-152-45/+20
|
* Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1998-04-151-13/+0
| | | | | | to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.
* Stack checker extension now accounted for in confdefs.hJoel Sherrill1998-04-141-8/+0
|
* Now accounts for region used by RTEMS malloc and extension usedJoel Sherrill1998-04-141-14/+0
| | | | by newlib.
* Moved bsp_postdriver_hook() to a shared file and made it a commonJoel Sherrill1998-03-302-28/+3
| | | | component.
* Added BSP specific start since it had become VERY complex to attemptJoel Sherrill1998-03-213-1/+325
| | | | to share the start code across i386 BSPs.
* Switch to using a shared main() for all of the embedded BSPsJoel Sherrill1998-03-212-16/+2
| | | | | | | | based on the GNU tools. This usually involved correcting the type of bsp_start(), bsp_cleanup(), adjusting the start code to call the right start routine (the shared boot_card()), and then removing code from bsp_start() which was performed in the new boot_card()/main() path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Removed CONFIG_DIR and PROJECT_HOME directories.Joel Sherrill1998-01-208-8/+8

* 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!

* Switched all bsps which had an implementation of sbrk.c which onlyJoel Sherrill1997-04-151-1/+1

* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-018-0/+372
| | | | | | | | | | | | | | | | | | | | 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.

* The word "RTEMS" almost completely removed from the core.Joel Sherrill1995-09-114-65/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Configuration Table Template file added and all tests modified to use this. All gvar.h and conftbl.h files removed from test directories. Configuration parameter maximum_devices added. Core semaphore and mutex handlers added and RTEMS API Semaphore Manager updated to reflect this. Initialization sequence changed to invoke API specific initialization routines. Initialization tasks table now owned by RTEMS Tasks Manager. Added user extension for post-switch. Utilized user extensions to implement API specific functionality like signal dispatching. Added extensions to the System Initialization Thread so that an API can register a function to be invoked while the system is being initialized. These are largely equivalent to the pre-driver and post-driver hooks. Added the Modules file oar-go32_p5, modified oar-go32, and modified the file make/custom/go32.cfg to look at an environment varable which determines what CPU model is being used. All BSPs updated to reflect named devices and clock driver's IOCTL used by the Shared Memory Driver. Also merged clock isr into main file and removed ckisr.c where possible. Updated spsize to reflect new and moved variables. Makefiles for the executive source and include files updated to show break down of files into Core, RTEMS API, and Neither. Header and inline files installed into subdirectory based on whether logically in the Core or a part of the RTEMS API.
