* Patches rtems-rc-20000118-3.diff and rtems-rc-20000118-4.diff fromJoel Sherrill2000-01-3113-213/+165
| | | | | | | | | | Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain: * Modifications, (minor) corrections, cleanups to most existing Makefile.ams * Adds automake support to all remaining BSPs which have not yet been converted to automake. * Makefile.am for all remaining wrapup/Makefile.ams
* Added after report from Quality Quorum <qqi@world.std.com> thatJoel Sherrill2000-01-271-0/+5

| | | | | | | | | | | | | | | | | | | | I'd like to propose a change to RTEMS task variables that I think would make them more useful. I think that it is early enough in their existence to still make changes to their API. 1) Change type from `int' to `void *'. 2) Add extra argument to task_variable_add -- if non-NULL, a pointer to a `destructor' function to be called when the task exits. This function would be called with that task's value of the task variable as its argument. In many cases, the `dtor' function could be `free'. rtems_status_code rtems_task_variable_add ( rtems_id tid, void **ptr, void (*dtor)(void *)); rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr); This would be all we'd need to cleanly and efficiently support C++ per-thread exception information without dragging in all that POSIX API stuff.

* POSIX message queues now include complete functionality includingJoel Sherrill2000-01-135-89/+154
| | | | | | | | | | | | | | | | blocking sends when the queue is full. The SuperCore was enhanced to support blocking on send. The existing POSIX API was debugged and numerous test cases were added to psxmsgq01 by Jennifer Averett. SuperCore enhancements and resulting modifications to other APIs were done by Joel. There is one significant point of interpretation for the POSIX API. What happens to threads already blocked on a message queue when the mode of that same message queue is changed from blocking to non-blocking? We decided to unblock all waiting tasks with an EAGAIN error just as if a non-blocking version of the same operation had returned unsatisfied. This case is not discussed in the POSIX standard and other implementations may have chosen differently.

* Added support for simple binary semaphores in addition to the highJoel Sherrill2000-01-057-63/+77
| | | | | | | | | | | | power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <eric@cls.usask.ca> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority.

Modifications had been made to the score/cpu/powerpc directory after the snapshot this was based on. In particular, the mpc750 and other_cpu directories had been renamed to new_exception_processing and old_exception_processing. After this patch was applied, modifications were made to account for this.

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.

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

* Only check for System V IPC if multiprocessing is enabled. The unixJoel Sherrill1999-11-162-1/+11
| | | | | | | | 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 Sherrill1999-11-094-23/+57

* This is another pass at making sure that nothing outside the BSPJoel Sherrill1999-11-0512-2/+167
| | | | | | | | | | | | 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.
