* Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill2000-06-131-95/+0
| | | | | | now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.
* Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill2000-06-121-0/+136
| | | | | | | | | | | | | | | <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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <corsepiu@faw.uni-ulm.de> which implements automake support for some score/cpu/<RTEMS_CPU> subdirectories and fixes a few minor configuration bugs. To apply: rm -rf c/src/exec/score/cpu/a29k/wrap rm -rf c/src/exec/score/cpu/hppa1.1/wrap rm -rf c/src/exec/score/cpu/i386/wrap rm -rf c/src/exec/score/cpu/mips64orion/wrap rm -rf c/src/exec/score/cpu/no_cpu/wrap patch -p1 < rtems-rc-19991123-rc-2.diff.gz Notes: * I don't see a possiblity to convert the powerpc subdirectory in its current layout to automake the time being. * Besides the fact that this subdirectory is not in single-tree building layout, the actual showstopper is the ifeq $(RTEMS_CPU_MODEL),mpc750) gmake-conditional in powerpc/Makefile.in, which automake (correctly) refuses to handle. * The problem is *not* specific to the powerpc. Other CPUs basically have similar problems (SH:sh7032 vs sh7045, SPARC: erc32.h in score/cpu/sparc), but have been lucky to get around real issues (cf. configuration files below score/cpu/sh/). * From a configuration focused POV this problem boils down to a file/subdirectory selection problem: ppc: 1 or others sh: 1 out of 2 sparc: 1 out of 1 Automake's means to implement such behavior is using conditionals to be evaluated at configuration-time. The old configuration scheme however used make-time conditionals. The SH port was lucky to get around this issue because it applies a selection from a limited set of possible selections, the powerpc however applies a selection from an unlimited set, based on data not being available at configuration time. * Currently I only see two general solutions: 1) make RTEMS_CPU_MODEL available at configuration time, ie. replace make-time configuration by configuration-time configuration 2) Perform the selection at build-time, i.e. always install all files, but use #ifdef #else #endif in source files. This is what the m68k has exploited at other locations inside of the source-tree. => This directory is the last one remaining not using automake below the whole exec/ hierarchy.

* This is another pass at making sure that nothing outside the BSPJoel Sherrill1999-11-051-0/+15
| | | | | | | | | | | | 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>.
* Removed targets and configurations that are no longer functionalJoel Sherrill1999-10-053-33/+0
| | | | | | | | | | | | | | and not likely to become so. Comments on each configuration are below. + Force CPU386 - This BSP was developed as part of the initial port of RTEMS to the i386. This board has been unavailable for a long time now. + GO32 - This BSP and some CPU code supported djgpp v1.x. This version is now quite old. No one has stepped forward to update the code to v2.x which may be technically impossible anyway. More importantly, go32 has been superceded by the pc386 BSP.

* Patch from Emmanuel Raguet <raguet@crf.canon.fr>:Joel Sherrill1999-02-181-1/+9
| | | | | | | You will find enclosed a patch which contains, for Intel PC386 target : - an Ethernet driver for DEC21140 device based boards. - a simple cache management with paging mechanism.
* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> to rename allJoel Sherrill1998-12-141-0/+282
| | | | | .s files to .S in conformance with GNU conventions. This is a minor step along the way to supporting automake.

This patch fixes the two problems mentionned above + it use vpath mechanism intead of copying the irq related files in the right directory. This avoid to compile them each time and is more homogenous with other Makefiles.

* Patch from Eric VALETTE <valette@crf.canon.fr>:Joel Sherrill1998-07-231-99/+0
| | | | | | | | | | | | | Here is a enhanced version of my previous patch. This patch enables to potentially share the new interrupt management code for all Intel targets (pc386, go32 and force386) bsp. Note : this patch is complete only for pc386. It still needs to be completed for go32 and force386. I carrefully checked that anything needed is in for force386 (only some function name changes for IDT manipulation and GDT segment manipulation). But anyway I will not be able to test any of theses targets...

* The word "RTEMS" almost completely removed from the core.Joel Sherrill1995-09-113-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
