| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .. a major configuration cleanup ... major enhancement of automake support. ... and it contains a *major* breakthough: Automake support for libchip and libmisc *LEAF* directories. To implement this I have used several nasty tricks * The basical trick is to wrap an old Makefile.in's contents into a Makefile.am and still continue to use (i.e include) the old *.cfg files. * Replaced each INSTALL_IF_CHANGE and INSTALL_VARIANT with make dependencies * Add a gnu-make ifdef AUTOMAKE to main.cfg to avoid conflicts between automake and RTEMS make rules * Replaced each install:: and preinstall:: rule with make dependencies * Replaced SUB_DIRS with SUBDIRS in all Makefile.ins (Automake convention) * Removed each manually added autoconf substitution which automake performs automatically. This is not yet full automake support, because using the temporary installation directory, preinstallation in general and building variants are in contradiction to automake's basic working principles ... ... the new Makefile.ams work still somewhat clumsy ... nevertheless they work (quite well). WARNING: At first glance this patch is small, but * it affects the whole configuration system. * it opens the road to introducing automake to all Makefile.ins currently not being under automake control. JOEL> Does this remove or add any files? Both, all Makefile.ins below libchip and libmisc get replaced with Makefile.ams.

* Patch from "John M. Mills" <jmills@tga.com> with subsequent cleanup fromJoel Sherrill1999-11-1810-651/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ralf Corsepius <corsepiu@faw.uni-ulm.de> that adds initial Hitachi SH-2 support to RTEMS. Ralf's comments are: Changes: ------ 1. SH-Port: * Many files renamed. * CONSOLE_DEVNAME and MHZ defines removed from libcpu. * console.c moved to libbsp/sh/shared, build in libbsp/sh/<BSP>/console applying VPATH. * CONSOLE_DEVNAME made BSP-specific, replacement is defined in bsp.h * MHZ define replaced with HZ (extendent resolution) in custom/*.cfg * -DHZ=HZ used in bspstart.c, only * Makefile variable HZ used in bsp-dependent directories only. 2. SH1-Port * clock-driver rewritten to provide better resolution for odd CPU frequencies. This driver is only partially tested on hardware, ie. sightly experimental, but I don't expect severe problems with it. * Polling SCI-driver added. This driver is experimental and completly untested yet. Therefore it is not yet used for the console (/dev/console is still pointing to /dev/null, cf. gensh1/bsp.h). * minor changes to the timer driver * SH1 specific delay()/CPU_delay() now is implemented as a function 3. SH2-Port * Merged * IMO, the code is still in its infancy. Therefore I have interspersed comments (FIXME) it for items which I think John should look after. * sci and console drivers partially rewritten and extended (John, I hope you don't mind). * Copyright notices are not yet adapted
* Added routine to remove an object from the namespace. It just clearsJennifer Averett1999-11-181-0/+17
| | | | | | | | | its name in the name_table. This was required by the POSIX semaphore and message queue managers which support a concept of open, close, and unlink. The object becomes "invisible" to further opens following an unlink but all open sessions remain active until they are closed. This requires that the removal of an object ID be separate from the removal of its name.

* Moved task_variable pointer to basic shared part of TCB instead ofJoel Sherrill1999-11-161-0/+15
| | | | | | | RTEMS API extension to avoid problems when the extension is freed. Eventually the task variable switch extension should become part of the core context switch and the Ada tcb self implemented in terms of it.

* Only check for System V IPC if multiprocessing is enabled. The unixJoel Sherrill1999-11-163-2/+15
| | | | | | | | port only uses System V IPC for shared memory and semaphores to communicate between nodes in a multiprocessor configuration. If you disable multiprocessing, then this code should be unused. Thus systems like Cygwin which are POSIX but do not support System V IPC should not work.

* This patch adds the basic framework for the ITRON 3.0 API implementationJoel Sherrill1999-11-096-23/+64

* This is another pass at making sure that nothing outside the BSPJoel Sherrill1999-11-0514-3/+235
| | | | | | | | | | | | unnecessarily uses any variables defined by the BSP. On this sweep, use of BSP_Configuration and Cpu_table was eliminated. A significant part of this modification was the addition of macros to access fields in the RTEMS configuration structures. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
* The files in libcpu should not be directly dependent on any BSP. InJoel Sherrill1999-11-042-2/+8
| | | | | | | | | | | particular, using bsp.h, or getting information from the BSP which should properly be obtained from RTEMS is forbidden. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>. The changes primarily eliminated the need to include bsp.h and peeking at BSP_Configuration. The use of Cpu_table in each BSP needs to be eliminated.
